The formulation of a complete diet consisting of elephant grass (Pennisetum purpureum) and complete feed can provide a more balanced supply of nutrients to meet the nutritional requirements of sheep. The complete feed is composed of various feed ingredients serving as sources of energy, protein, minerals, and feed supplements, including coffee husk, corn, rice bran, palm oil, copra meal, soybean meal, distillers dried grains with solubles (DDGS), CaCO&#8323-, dicalcium phosphate (DCP), salt, premix, FML, and molasses. Supplementation with turmeric (Curcuma longa) essential oil (EO) has the potential to influence microbial activity and rumen fermentation processes, thereby improving nutrient utilization. This study aimed to evaluate the effects of turmeric EO supplementation in the complete diet on nutrient intake and digestibility in local sheep. Ten local sheep were allocated according to a Randomized Block Design (RBD) with two treatments and five replications. The treatments consisted of a complete diet without turmeric EO supplementation (T0) and a complete diet supplemented with turmeric EO (T1). The parameters observed included dry matter (DM), organic matter (OM), crude protein (CP), and crude fiber (CF) intake, as well as the coefficients of digestibility of dry matter (DMD), organic matter (OMD), crude protein (CPD), and crude fiber (CFD). Data were analyzed using analysis of variance based on the RBD. The results showed that turmeric EO supplementation increased DM, OM, CP, and CF intake, with mean DM, OM, CP, and CF intakes in P0 of 635.70, 564.36, 91.98, and 185.77 g/head/day, respectively, compared with 681.22, 585.19, 96.62, and 194.16 g/head/day, respectively, in T1. The coefficients of DMD, OMD, CPD, and CFD in P0 were 52.94, 62.29, 93.75, and 84.19%, respectively, whereas those in T1 were 46.01, 56.25, 91.72, and 82.28%, respectively. Turmeric EO supplementation increased nutrient intake but did not result in a descriptive increase in nutrient digestibility coefficients. Statistical analysis was conducted to determine the effects of turmeric EO supplementation on nutrient intake and digestibility in local sheep Keywords: essential oil, complete feed, digestibility, intake, sheep Share Link | Plain Format | Corresponding Author (Anintya Noor Sasmita)

On Sheep Productivity Isthi Khabibah, Kusmartono, and Mashudi Faculty of Animal Science and Technology, Brawijaya University, Malang 65145, Indonesia Abstract This study aimed to evaluate the effect of substituting elephant grass (Pennisetum purpureum) as a fiber source with ground corn cobs (Zea mays L.). The variables observed were nutrient intake, nutrient digestibility, weight gain (WG), Feed Conversion Ratio (FCR), and Income Over Feed Cost (IOFC) in local sheep. The study used a Randomized Block Design (RBD) with 4 treatments and 5 blocks based on initial body weight, resulting in a total of 20 male sheep. The treatments administered were P0 (40% K + 60% RG), P1 (40% K + 50% RG + 10% TJG), P2 (40% K + 45% RG + 15% TJG), and P3 (40% K + 40% RG + 20% TJG). The ration consisted of 60% forage and 40% concentrate on a dry matter basis, with a 3% intake. The results showed that the average daily weight gain (PBB) reached 174.66 g/sheep/day, with a feed conversion ratio (FCR) of 4.34. This value indicates that approximately 4.34 kg of feed is required to produce 1 kg of weight gain. The average IOFC was Rp707,018 per head, while the average digestibility was 55.87%. Feed intake, based on the presented data, averaged 53.25%, particularly when 10% ground corn cobs were substituted for a portion of elephant grass.

BIOCONVERSION OF BROKEN RICE AND SOYBEAN MEAL USING BACILLUS SUBTILIS THROUGH SOLID-STATE FERMENTATION TO IMPROVE STARCH AND PROTEIN UTILIZATION Febtoni Valentino Rosi (a*), Heli Tistiana (b), and Eko Widodo (b) Faculty of Animal Science and Technology, Universitas Brawijaya Abstract Improvement of feed ingredient quality through microbial fermentation may enhance nutrient utilization by modifying carbohydrate and protein fractions. Bacillus subtilis is a microorganism for solid-state fermentation due to its ability to produce enzymes, particularly amylases and proteases. This study aimed to evaluate the effect of fermentation duration using Bacillus subtilis on starch conversion, soluble sugar production, and protein solubilization in a substrate containing broken rice and soybean meal. The substrate consisted of broken rice and soybean meal at a ratio of 5:3 and was fermented for 24, 48, and 72 hours. The experiment used a completely randomized design with three fermentation-duration treatments and six replications. The variables were starch, soluble sugar, and soluble protein contents. The results showed that fermentation duration affected starch conversion, soluble sugar production, and soluble protein. After 24, 48, and 72 hours of fermentation, starch content decreased from 56.00% to 54.69%, 52.88%, and 51.82%, respectively. Soluble sugar increased from 0.85% to 1.52%, 2.28%, and 2.13%, while soluble protein increased from 4.50% to 6.23%, 7.84%, and 8.39%, respectively. The highest soluble sugar concentration was happen after 48 hours, whereas soluble protein continued to increase until 72 hours. The decline in starch accompanied by increased soluble sugar indicated carbohydrate conversion, while increased soluble protein indicated protein solubilization during fermentation. Based on the overall responses of starch conversion, soluble sugar production, and protein solubilization, the 48-hour fermentation treatment provided the most favorable result among the measured variables and was considered the optimal fermentation duration under the conditions of this study.

Their coelomic fluid contains a variety of cellular and humoral components that may have important biological activities. The present study investigated a fluorescent compound isolated from the coelomic fluid of the earthworm Perionyx excavatus and examined its effects on mammalian fibroblast cells.Coelomic fluid was collected from Perionyx excavatus, processed with methanol, and subjected to thin layer chromatography. A distinct greenish yellow fluorescent band was observed under ultraviolet illumination and recovered for subsequent biological evaluation. The cellular effects of the isolated fluorescent fraction were investigated using fibroblast cell proliferation observations, BrdU labeling, and an MTT cell viability assay.The study showed concentration dependent differences in cellular responses. Greater apparent cell proliferation was observed at 2 ug compared with higher concentrations, whereas reduced cellular viability was observed at 30 and 40 ug in the BrdU based observations. In the MTT assay, approximately 90 percent cell viability was reported at 8 ug, indicating relatively low cytotoxicity at this concentration. A scratch wound assay was also performed to examine cellular migration under the tested conditions. The fluorescent fraction did not produce an apparent improvement in wound closure compared with the control after 36 hours.These findings indicate that the fluorescent fraction obtained from Perionyx excavatus coelomic fluid exhibits concentration dependent cellular effects and warrants further biochemical and molecular characterization. Future studies could combine conventional microscopy with artificial intelligence assisted bioimage analysis to objectively quantify fluorescence intensity and wound closure kinetics, thereby improving detailed characterization of the biological activity of earthworm derived fluorescent compounds.

New Hope, Mojokerto, East Java, Indonesia 61382 Abstract This study evaluated the physical quality, nutrient composition, and fiber fractions of fermented rice straw and rice straw-based fermented total mixed rations (TMR). Rice straw fermentation was evaluated using a factorial completely randomized design comprising 12 treatment combinations and three replicates per combination. Treatments combined four yeast starter levels of 0%, 2%, 4%, and 6% with three energy sources, namely rice bran, wheat pollard, and molasses, each added at 5%, followed by fermentation for 28 days. TMR containing previously fermented rice straw was evaluated using four treatments with rice straw inclusion levels of 30%, 40%, 50%, and 60%, each with four replicates. Physical quality and nutrient composition of fermented TMR were evaluated using four treatments containing 20%, 30%, 40%, and 50% concentrate on a dry matter basis, each with four replicates, 4% starter, and 21 days of fermentation. Fiber evaluation included these four TMR formulations and an untreated rice straw control, with four replicates per treatment. Fermented rice straw containing 4% starter and 5% pollard had the highest observed crude protein content of 11.76%. In TMR containing previously fermented rice straw, nutrient and fiber contents differed significantly among treatments (P < 0.01), whereas physical quality did not (P > 0.05). In the 21-day fermented TMR, the treatment containing 50% concentrate had the highest dry matter, organic matter, and crude protein contents of 75.12%, 85.11%, and 11.96%, respectively. The lowest observed neutral detergent fiber, acid detergent fiber, and cellulose contents were 67.32%, 29.51%, and 8.95% in treatments containing 50%, 20%, and 40% concentrate, respectively. Hemicellulose did not differ significantly, and lignin was not reduced relative to untreated rice straw.

Heavy Metal Contamination and Dietary Health Risk of Telescopium telescopium from Hinatuan, Surigao del Sur, Philippines Raffy C. Otaza (a), John Paul B. Sabino (a), Michael M. Panamogan (a), Joey Olivar (a), Jaynos R. Cortes (a)* (a) Department of Fisheries Sciences, College of Fisheries and Aquatic Sciences, North Eastern Mindanao State University - Lianga Campus, Lianga, Surigao del Sur, Philippines Abstract Heavy metal contamination in edible mangrove associated gastropods may represent an important dietary exposure pathway for coastal communities. This study determined concentrations of lead (Pb), arsenic (As), cadmium (Cd), and mercury (Hg) in the edible soft tissues of Telescopium telescopium collected from Barangay Tiwi and Barangay Sto. Nino, Hinatuan, Surigao del Sur, Philippines, and evaluated potential dietary health risks associated with metal exposure. Pb and As were below the analytical reporting limits of 0.10 mg/kg and 0.05 mg/kg, respectively, whereas Cd and Hg were quantified. Mean Cd concentration was higher in Tiwi at 0.0744 plus or minus 0.0028 mg/kg than in Sto. Nino at 0.0314 plus or minus 0.0046 mg/kg. Mercury showed the opposite pattern, with higher concentrations in Sto. Nino at 0.0455 plus or minus 0.0163 mg/kg than in Tiwi at 0.0228 plus or minus 0.0058 mg/kg. Estimated daily intake, health based guidance value comparisons, target hazard quotient, and hazard index were calculated for children and adults using barangay level quantified concentrations. Cumulative hazard index values were 0.214 and 0.145 for children and adults, respectively, in Tiwi, compared with 0.344 and 0.233 in Sto. Nino. All values were below the screening benchmark of 1. Mercury was the dominant contributor to cumulative hazard, accounting for 75.2 percent of child hazard index in Tiwi and 93.6 percent in Sto. Nino. Deterministic consumption risk scenario modelling estimated that the hazard index would reach 1 at 99.1 and 197.9 g/day for children and adults in Tiwi, and 61.6 and 123.2 g/day, respectively, in Sto. Nino. These findings indicate higher modeled non carcinogenic hazard in Sto. Nino under the specified exposure assumptions and highlight the value of site specific monitoring and consumption risk assessment for edible mangrove gastropods in local coastal communities.

Closing the Nutrient Loop: Black Soldier Fly Larvae as Sustainable Feed for Poultry Production Nur Maulida Wahyuni , Binti Ma^rifah, Teysar Adi Sarjana, Rina Muryani, Hanna Dzawish Shihah, Edjeng Suprijatna, Bambang Sulistiyanto, Cahya Setya Utama, Sugiharto Sugiharto Department of Animal Science, Faculty of Animal and Agricultural Sciences, Universitas Diponegoro, Semarang 50275, Central Java, Indonesia Abstract This review aims to evaluate the potential of black soldier fly larvae (BSFL Hermetia illucens) as a sustainable feed resource that closes the nutrient loop in poultry production by converting organic residues into feed ingredients. A narrative synthesis of 32 peer reviewed sources shows that BSFL contain 35-60% crude protein on a dry matter basis, with a lysine and methionine-rich amino acid profile competitive with soybean meal. The lipid fraction (15-45% of dry matter) is dominated by lauric acid, which is associated with antimicrobial and gut health benefits. Both fractions vary markedly with rearing substrate. BSFL are supplied to poultry as fresh larvae, full fat meal, defatted meal (55-65% protein), or extracted oil, including a saponified calcium salt form with improved oxidative stability. At moderate inclusion levels, these products maintain or improve growth and feed efficiency in broilers, sustain egg production and yolk colour in laying hens, and enhance egg quality and lipid metabolism in quail. Wider adoption depends on substrate standardisation, harmonised ingredient specifications, context-specific economic assessment, and further quail specific research. BSFL therefore serve as both a feed resource and a waste-treatment technology within a circular poultry bioeconomy.

E-mail: hemasnidhal[at]gmail.com 2Faculty of Animal Science and Technology, Universitas Brawijaya, Malang 65145, Indonesia. Abstract Derived from agro-industrial processing, apple pomace serves as an excellent resource of dietary fiber and biologically active compounds is a promising functional substance for food applications. Its incorporation into chicken sausage may improve physicochemical properties while adding value to apple-processing residues. The impact of apple pomace flour on physicochemical parameters, color, and texture of full-fat chicken sausage was examined in this study. A completely randomized design was employed, comprising four treatments with six replicates, in which apple pomace flour was added at 0, 3, 6, and 9% of chicken meat weight. The parameters measured were pH, cooking loss, water-holding capacity (WHC), fat content, moisture content, color, and texture. Apple pomace flour addition affected physicochemical properties, particularly water retention, cooking loss, and WHC. The results indicated that it increased pH and WHC and improved color and texture, whereas cooking loss, moisture content, and fat content decreased. Increasing the level of apple pomace flour affects the product^s texture and color. These outcomes are related to the water-absorption capacity of the ingredient of the fiber matrix, which can interact chemically with water and meat proteins within the sausage matrix. Overall, apple pomace flour shows potential as a high-quality functionality ingredient and offers sustainable alternatives for utilizing fruit by-products in processed meat products applications.

A completely randomized design (CRD) was conducted with four pumpkin puree supplementation levels [0% (P0), 3% (P1), 5% (P2), and 7% (P3) w/w] across four replications. Evaluated parameters included proximate composition, titratable acidity, pH, viscosity, syneresis, CIELAB color coordinates (L(asterisk)a(asterisk)b(asterisk)), beta-carotene, total dietary fiber (TDF), crude fiber, antioxidant activity, total lactic acid bacteria (LAB) counts, and sensory attributes. Optimal formulation was identified using Multiple-Attribute Decision Making (MADM) and Principal Component Analysis (PCA). Addition of pumpkin puree significantly increased (p < 0.01) pH, viscosity, color values, antioxidant activity, beta-carotene content, total dietary fiber, crude fiber, and sensory scores for taste and aroma. It also significantly influenced (p < 0.05) total acidity and texture scores. Proximate parameters (protein, fat, and moisture content), syneresis, and total viable LAB counts were not significantly altered (p > 0.05). Treatment P3 (7% pumpkin puree) yielded the highest hedonic scores for color and texture. Fortification with 7% pumpkin puree (P3) significantly enhances the functional, bioactive, and textural properties of cow-milk yogurt while retaining essential probiotic viability and core nutritional composition.

Porang (Amorphophallus muelleri) Flour as a Natural Stabilizer in Goat Milk Gelato: Effects on Melting Resistance, Fat and Protein Content, and Sensory Acceptance Felia Almira Marva Putri (a), Aris Sri Widati (b), Premy Puspitawati Rahayu (b), Lilik Eka Radiati (b) a) Graduate Student, Department of Animal Product Technology, Faculty of Animal Science, Universitas Brawijaya, Malang, Indonesia b) Lecturer, Department of Animal Product Technology, Faculty of Animal Science, Universitas Brawijaya, Malang, Indonesia Abstract Goat milk gelato adds value to goat milk and masks its characteristic odour, but the low-fat content and low overrun of gelato make it melt quickly. Porang (Amorphophallus muelleri) flour is rich in glucomannan, a highly water-binding hydrocolloid that could serve as a natural alternative to synthetic stabilizers such as CMC. This study evaluated the effect of porang flour on the melting resistance, fat and protein content, and sensory acceptance of goat milk gelato. A completely randomized design was applied with five levels of porang flour (0, 0.2, 0.4, 0.6, and 0.8% of mix weight) and four replicate batches. Melting resistance was measured as the time required for 10 g of gelato to melt completely at room temperature, fat content by Soxhlet extraction, protein content by formol titration, and acceptance by a 7-point hedonic test with 25 untrained panelists. Data were analysed by ANOVA followed by Duncan^s multiple range test. Porang flour significantly increased melting time (P<0.01) in a dose-dependent manner, from 9.01 min/10 g in the control to 30.38 min/10 g at 0.8%. Fat content was also significantly affected (P<0.01): gelato containing 0.4-0.8% porang flour (8.55-9.47%) had higher fat content than the control (6.54%), possibly because the more stable emulsion kept more fat within the product. Protein content was not significantly affected (2.89-3.88%- P>0.05), and all treatments met the Indonesian National Standard minimum requirements for fat (5.0%) and protein (2.7%). Porang flour decreased texture acceptance (P<0.01- from 6.12 to 5.08) and colour acceptance (P<0.05- 6.03 in the control vs. 5.53-5.78), whereas aroma and taste scores were not significantly affected (P>0.05). Porang flour effectively slows the melting of goat milk gelato, but its inclusion level should balance melting resistance against texture acceptance.

Effect of Potato Peel Flour Addition on the Physicochemical Properties of Beef Patties Maria Apriliana Ade Karlina1, Herly Evanuarini2*, Nurul Isnaini2, Agus Susilo2, Sri Wahjuningsih2, Irida Novianti2, and Premy Puspitawati Rahayu2 1Student at Faculty of Animal Science and Technology, Universitas Brawijaya, Malang E-mail: mariakarlin20[at]gmail.com 2Lecture at Faculty of Animal Science and Technology, Universitas Brawijaya, Malang Abstract Beef patties are processed meat products whose physicochemical characteristics can be influenced by the incorporation of functional ingredients. Potato peel has the potential to be utilized as a food ingredient due to its functional components. This study aimed to investigate the effect of potato peel flour addition on the physicochemical characteristics of beef patties and to determine the level of addition that produced the most desirable characteristics. The study employed a laboratory experimental method using a Completely Randomized Design (CRD) consisting of four treatments and five replications. Potato peel flour was incorporated at levels of 0%, 2%, 4%, and 6% based on the weight of the formulation. The observed parameters included moisture content, fat content, water-holding capacity (WHC), cooking loss, pH, texture, and color characteristics, including L*, a*, and b* values. The results showed that increasing the level of potato peel flour addition decreased the moisture content, fat content, cooking loss, and pH, while increasing the WHC of beef patties. The addition of potato peel flour also affected the color and texture characteristics of the beef patties. The addition of 2% potato peel flour produced the most desirable physicochemical characteristics based on the parameters evaluated. Potato peel flour has potential as an ingredient in beef patty formulations and as an alternative for valorizing potato processing by-products into value-added food products.

Characteristics and Functions of Pectin as a Stabilizer in Dairy Products: A Review Hilya Hanifah1, Rahmalia Azmi1, Dayang Wintadiningrat1, Premy Puspitawati Rahayu1*, Mulia Winirsya Apriliyani1, Angelica Denta Pradiesta Putri1, Ius Paring Panggih Tirta1, and Fauziyah Nisa Syifa1 1Faculty of Animal Science and Technology, Universitas Brawijaya, Malang 65141, Indonesia *)Corresponding author: premypuspita[at]ub.ac.id Abstract Pectin is a plant-derived polysaccharide widely used as a functional ingredient in food products due to its ability to modify texture, water retention, and colloidal stability. In dairy products, pectin is increasingly being studied as a natural stabilizer, particularly in fermented products that are prone to increased syneresis and decreased viscosity. This review discusses the characteristics of pectin and its relationship to its stabilizing function in various processed dairy products. Pectin^s ability to act as a stabilizer is influenced by several factors, including the source of pectin, degree of esterification, molecular weight, concentration, processing conditions, and the characteristics of the milk matrix. The interaction of pectin with milk proteins, particularly casein, plays a role in forming and maintaining the structure of the milk system, thereby influencing syneresis and viscosity. Various studies have shown that the use of pectin can improve the physical characteristics and stability of dairy products, but the resulting response depends on the type and concentration of pectin as well as the product characteristics. Therefore, an understanding of pectin^s characteristics and its interaction mechanisms within the milk matrix is important for determining its use as a stabilizer in processed dairy products.

YOLOv11 Configuration with a GhostConv Efficiency Module for Sex Detection of Broiler Day-Old Chicks Based on Wing Feather Images Rika Sulistia1, Azzahroh Septariana Widayanti1, Mochamad Tono1,2, and Muhammad Halim Natsir1 Faculty of Animal Science and Technology, Universitas Brawijaya Abstract Abstract. Sex determination of broiler day-old chicks (DOC) is an essential step in commercial hatcheries. Feather sexing is non-invasive, but its accuracy depends on operator consistency. This study applied the Ghost Convolution (GhostConv) efficiency module to YOLOv11-n for DOC sex detection based on wing feather images and tested whether the lighter model could match the performance of the baseline. The dataset consisted of 4,374 wing images of Ross 308 and Cobb 500 DOC split at a 70/20/10 ratio, and the training set was augmented to 12,240 images. The baseline and GhostConv configurations were each trained from scratch five times with different seeds and evaluated on 438 test images. GhostConv reduced the number of parameters by 11.8% (from 2.590 M to 2.284 M) and the model size by 10.9% (from 5.22 MB to 4.65 MB). The mean mAP@0.5 of GhostConv was 95.21% compared with 95.66% for the baseline, with F1-scores of 92.25% and 92.23%, respectively. Welch^s t-test showed no significant difference in any detection metric (p > 0.05). GhostConv produced a lighter model with performance equivalent to the baseline, making it suitable for further development of DOC sex detection on mobile devices.

Physicochemical Properties of Gelatin Edible Film and Functional Cheese Slice Enriched with Yellow Pumpkin (Cucurbita moschata) Extract Dela Dafista, Putri Selvia Nurfebriana, Tri Mey Wulansari, Abdul Manab Universitas Brawijaya Abstract Yellow pumpkin (Cucurbita moschata) is a good source of the natural antioxidant pigment beta-carotene and has previously been incorporated into gelatin-based active edible film and functional cheese slice, in which its effect on antimicrobial activity, water vapor permeability, mechanical and optical strength, and the casein proteome has been reported. The present study evaluated physicochemical properties of the same pumpkin-extract system that have not previously been reported, namely the color profile (lightness L*, redness a*, yellowness b*), water activity (Aw), and moisture content of the gelatin edible film, together with the protein content and free oil of the functional cheese slice enriched with pumpkin extract. A completely randomized design (CRD) with four levels of pumpkin extract (P0 = 0%, P1 = 5%, P2 = 10%, P3 = 15%) and three replications was applied separately to the edible film (v/v addition) and the functional cheese slice (w/w addition). The addition of pumpkin extract had a highly significant effect (P<0.01) on the yellowness (b*) of the edible film, which increased from 3.45 in P0 to 6.55 in P3, but no significant effect (P>0.05) on lightness (L*, 90.18-90.71) or redness (a*, 0.46-0.66). Water activity (0.53-0.57) and moisture content (8.36-8.77%) of the film were not significantly affected (P>0.05) by the treatments. Likewise, the protein content (12.50-14.66%) and free oil (68.90-69.91%) of the functional cheese slice were not significantly affected (P>0.05) by pumpkin extract level. These results indicate that pumpkin extract enhances the natural yellow color of the edible film in a dose-dependent manner without altering its water-related stability, and that its incorporation into functional cheese slice does not compromise the protein content or oil-holding capacity of the product.

Abstract Sex determination remains a practical challenge for breeders of Kampung Unggul Balitbangtan (KUB) Chickens. This study examined egg morphometric parameters and phenotypic characteristics of day-old chicks (DOC) as indicators of embryo sex, which was determined via CHD1 gene based molecular sex determination, and documented post-hatch growth performance. A total of 75 KUB hatching eggs were incubated- 74 of these were fertile and 69 were sexed via CHD1 based PCR amplification analysed by microchip electrophoresis. Egg morphometric measurements, such as mass, length, width, volume, surface area and Egg Shape Index (ESI), were taken before incubation. Nineteen healthy DOC were monitored post-hatching. Egg length was the only morphometric parameter significantly associated with embryo sex. Eggs containing male embryos were longer than those containing female embryos (P=0.039- Cohen^s d=0.945). Male DOC tended to be heavier (d=0.503), whilst yellow beak and leg colour showed a consistent trend towards the male sex (72.7 per cent). Differences in post-hatch body weight showed distinct values by Week 7. These findings provide information on the morphometric indicators of eggs and DOCs of native chicken. It can be used to develop practical, low cost and non-invasive sex prediction indicators in the future for native chicken breeding operations.

E-mail: rinileke[at]yahoo.com 2 Faculty of Mathematics and Natural Sciences, Sam Ratulangi University, Manado, Indonesia. Email: ratna siahaan[at]unsrat.ac.id Abstract This study evaluated the effects of graded dietary clove essential oil (CEO) supplementation on egg quality in laying hens. Clove essential oil derived from Syzygium aromaticum was evaluated as a natural phytogenic feed additive with potential to improve physical and internal egg quality. A total of 25 observations were assigned to five dietary treatments with five replicates per treatment: P0, basal diet without CEO- P1, 0.15% CEO- P2, 0.30% CEO- P3, 0.45% CEO- and P4, 0.60% CEO. Egg weight, yolk weight, yolk color, albumen height, albumen width, shell thickness, and Haugh unit were evaluated. Data were analyzed using one-way analysis of variance followed by Tukey^s HSD test at a significance level of 5%. Dietary CEO supplementation significantly affected egg weight, yolk color, albumen height, and albumen width (P < 0.05), whereas yolk weight and shell thickness were not significantly affected (P > 0.05). Egg weight increased from 59.15 g in P0 to 64.00 g in P4, while albumen height increased from 7.27 to 8.58 mm. Haugh unit values ranged from 85.05 to 91.66, with the highest numerical value observed at 0.60% CEO supplementation. These findings indicate that graded dietary clove essential oil supplementation may influence selected physical and internal egg-quality characteristics in laying hens.

Abstract Birth weight and morphometric measurements are important indicators of early growth and may support performance evaluation and selection in Silangit buffalo. This study aimed to evaluate birth weight and morphometric characteristics of Silangit buffalo calves in North Sumatra and to determine the effects of maternal parity, calf sex, and sire. The traits evaluated were body weight (BW), chest girth (CG), body length (BL), withers height (WH), and hip height (HH). Maternal parity was classified as 1, 2, 3, and 5 or higher, while six sires (CAESAR, S-0025, S-0166, S-0167, S-0168, and S-0169) were evaluated. Data were analyzed using a linear model and expressed as least square means (LSMeans) with standard errors (SE), with significance declared at P < 0.05. Maternal parity significantly affected BW and CG, but not BL, WH, or HH. Birth weight increased from 30.76 +/- 1.05 kg in first parity dams to 32.20 +/- 1.07 kg in second parity and 36.66 +/- 1.60 kg in third parity, while calves from dams with parity 5 or higher averaged 35.15 +/- 1.95 kg. Chest girth showed a similar pattern, increasing from 70.70 +/- 1.45 cm in first parity to 77.16 +/- 2.20 cm in third parity. Calf sex and sire had no significant effects on any evaluated trait (P > 0.05). These findings indicate that maternal parity is an important source of variation in neonatal body size and should be considered in early growth evaluation and breeding programs for Silangit buffalo in North Sumatra.

Abstract This study aimed to evaluate the effect of oocyte collection method on the diameter and morphological grade of oocytes obtained from the ovaries of adult local goats processed at a slaughterhouse. Ovaries were divided into two treatment groups, namely aspiration and aspiration followed by slicing, and processed at the Bioscience Laboratory, Universitas Brawijaya. We evaluated 159 viable oocytes: 122 from 45 ovaries in the aspiration group and 37 from 17 ovaries in the aspiration-followed-by-slicing group. We analysed oocyte diameter and recovery rate using the Mann Whitney U test, and oocyte grade using the Chi-square test. Oocyte diameter was significantly larger in the aspiration group than in the aspiration followed by slicing group. Oocyte grade distribution differed significantly between the two methods, with aspiration followed by slicing producing a higher proportion of grade A and a lower proportion of grade C oocytes. However, the proportion of good-quality oocytes (grade A and B) and the recovery rate per ovary did not differ significantly between methods. These findings indicate that adding a slicing step after aspiration changes oocyte grade composition without improving the overall oocyte yield or the proportion of usable oocytes.

The study used an observational field study involving 55 recipient cows divided into two groups based on inseminator: Inseminator 1 (n = 29) and Inseminator 2 (n = 26). Inseminator 1 was 41 years old with 8 years of experience, while Inseminator 2 was 38 years old with 15 years of experience. Both inseminators held certificates and practice licenses from the East Java Provincial Livestock Service. AI success was evaluated based on the Non-Return Rate (NRR-1 and NRR-2) and Conception Rate (CR). Data were analyzed descriptively and using the chi-square test and Fisher^s exact test. The results showed that Inseminator 1 achieved NRR-1, NRR-2, and CR values of 79.31%, 55.17%, and 24.14%, respectively, while Inseminator 2 achieved values of 84.62%, 46.15%, and 34.62%, respectively. Although descriptive differences were observed in AI success between the two inseminators, statistical analysis showed that these differences were not significant (p > 0.05).

Effects of Hatching Egg Storage Duration at Room Temperature on Embryonic Characteristics of Japanese Quails Citra Galih Sriwahyuningrum1, Faizal Andri1, Aulia Puspita Anugra Yekti1, Hanief Eko Sulistyo1, and Nurul Isnaini1,* 1Faculty of Animal Science and Technology, Universitas Brawijaya, Malang 65145, Indonesia *Corresponding author: nurulisna[at]ub.ac.id Abstract The quality of hatching eggs prior to incubation plays a crucial role in embryonic development in Japanese quails. However, in small-scale production systems, quail eggs are often stored at room temperature before incubation, which may adversely affect subsequent embryonic development. This study evaluated the effects of hatching egg storage duration at room temperature on embryonic characteristics of Japanese quails. The study was conducted using an experimental design with two egg storage treatments: 0 and 7 days, with five replicates per treatment. Eggs were stored at room temperature (26-27 degree Celsius) before incubation. Embryonic characteristics were evaluated on day 9 of incubation by measuring embryo weight, length, and width, heart rate, eye length and width, and leg, wing, and tail lengths. Data were analyzed using an independent-samples t-test to compare the means between the two egg storage treatments. The results showed that storing eggs for 7 days significantly reduced embryo weight and length compared with eggs incubated immediately after collection, whereas embryo width was not significantly affected. Heart rate, eye length and width, and leg, wing, and tail lengths did not differ significantly between treatments. In conclusion, storing Japanese quail hatching eggs at room temperature for 7 days adversely affected embryonic development, particularly embryo weight and length. These findings indicate that minimizing the storage duration of hatching eggs before incubation is important for maintaining optimal embryonic growth.

Genome-Wide Association Studies of Carcass and Meat-Related Traits in Cattle: A Systematic Review Wari Wari (a), Irida Novianti (a*), Veronica Margareta Ani Nurgiartiningsih (a), and Cynthia D.K. Bottema (b) a) Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia *i_novianti[at]ub.ac.id b) Davies Livestock Research Centre, School of Animal & Veterinary Sciences, Adelaide University, Roseworthy Campus, Roseworthy, South Australia 5371, Australia Abstract Carcass and meat-related traits in cattle are complex quantitative phenotypes influenced by numerous genetic variants involved in muscle development, carcass composition, fat deposition, and meat quality. Genome-wide association studies (GWAS) have been widely applied to identify genomic regions underlying these traits- however, reported associations vary across breeds, populations, phenotype definitions, genotyping platforms, and analytical approaches. The aim of this systematic literature review was to synthesize GWAS findings on carcass and meat-related traits in cattle to identify recurrent genomic regions, candidate genes, and biological mechanisms associated with variation in meat production phenotypes. Relevant studies were evaluated for population characteristics, phenotypes, genotyping approaches, statistical methods, significant genomic regions, and reported candidate genes. Based on the current evidence set, 20 studies published between 2011 and 2026 were reviewed, covering Bos indicus, Bos taurus, tropical composite, Hanwoo, Angus, and Piemontese cattle, as well as cross-population and meta-analytic studies. Investigated phenotypes included muscle and meat yield, carcass composition, individual meat cuts, and meat quality traits. Across studies, BTA2, BTA6, BTA7, BTA12, BTA14, and BTA20 were among the most recurrent chromosomes associated with meat-related phenotypes. Frequently reported candidate genes included LCORL, NCAPG, PLAG1, XKR4, LAP3, FAM184B, LYN, MSTN, CAST, DGAT1, and FABP4. Collectively, the findings indicate a largely polygenic architecture involving biological processes related to muscle development, skeletal growth, lipid metabolism, adipogenesis, focal adhesion, and extracellular matrix-receptor interactions. These findings highlight recurrent genomic regions and candidate genes that may support functional validation and genomic selection for improved meat production in cattle.
