Evaluation of Bio-composite Mycotoxin Binder Based on Rice Husk Biochar, Zeolite, and Saccharomyces cerevisiae on Maize as Poultry Feed Ingredient Nofi Isnaini1, Yuli Frita Nuningtyas2, Feri Eko Hermanto2, and Muhammad Halim Natsir2* Please Just Try to Submit This Sample Abstract You Can Edit It Again Later Abstract Mycotoxins in maize are a major concern in poultry nutrition, as they reduce nutrient quality and pose risks to animal health. This study aimed to evaluate the potential of a bio-composite composed of rice husk biochar, zeolite, and Saccharomyces cerevisiae yeast in suppressing mycotoxin presence in maize. The experimental treatments consisted of a control without binder (P0) and three bio-composite formulations with different ratios of rice husk biochar, zeolite, and S. cerevisiae: 1:1:1 (P2), 1:2:2 (P3), and 2:1:1 (P4). Each treatment was replicated four times, with 200 g of maize per replicate, mixed with 1% binder, and incubated in sealed containers for five days. The observed parameters included moisture content measured using a digital moisture tester and mycotoxin indication assessed under UV fluorescence. Data were analyzed descriptively to illustrate trends during incubation. Preliminary results are expected to demonstrate the effectiveness of the bio-composite in reducing mycotoxin indication, thereby supporting the development of safer and more sustainable poultry feed.

The yogurt was made using skim milk powder and the lactic acid bacteria strains Lactobacillus bulgaricus and Streptococcus thermophilus as the main ingredients. The synbiotic yogurt was made using different concentrations of pomegranate peel extract at T0 (control), T1 (0.5%), T2 (1%), and T3 (1.5%). Synbiotic yogurt is susceptible to physical damage, which will have an impact on the decline in its physical and sensory characteristics. Physical characteristic tests include the pH, syneresis and water holding capacity. Sensory analysis was conducted on 30 panelists using a 5-point Likert scale with test parameters including aroma, taste, color and total acceptance. The results revealed significant differences (P<0.05) in the pH, syneresis and sensory aroma values of synbiotic yogurt. The addition of pomegranate peel extract to yogurt resulted in an average pH between 4.07-4.30, syneresis between 34.80-44.38% and aroma value of 3.77-4.12. In terms of sensory quality, yogurt with the addition of pomegranate peel extract was almost identical to the control, except for T2 due to its strong sour aroma. In conclusion, synbiotic yogurt with 0.5% pomegranate peel extract was the best of all the treatments. Thus, the pomegranate peel extract formulated into yogurt can be considered as a functional ingredient to improve the physical and sensory characteristics of yogurt.

Study on Different Management Practices on Quality and Quantity of Milk Produced by Dairy Farmers Dr. Sunil Manikrao Gaikwad and Dr. Balaji Kisan Ghule Deptt. of Dairy Science, Sanjeevanee Mahavidyalaya (College), Chapoli Tq. Chakur Dist. Latur (MS) INDIA Abstract Adulteration in milk has been a cause of concern for both the Government and the Dairy Industry. The Indian Council of Medical Research has reported that ^milk adulterants have hazardous health effects. The detergent in milk can cause food poisoning and other gastrointestinal complications. Its high alkaline level can also damage body tissue and destroy proteins. Other synthetic components can cause impairments, heart problems, cancer or even death. While the immediate effect of drinking milk adulterated with urea, caustic soda and formalin is gastroenteritis, the long-term effects are far more serious. Milk is most commonly diluted with water - this not only reduces its nutritional value, but contaminated water can also cause additional health problems. The other adulterants used are mainly detergent, foreign fat, starch, sodium hydroxide (caustic soda), sugar, urea, pond water, salt, maltodextrin, sodium carbonate, formalin, and ammonium sulphate. Investigators guided dairy farmers regarding the good management practices to be adopted. Milk samples before the guidance and after the guidance has been analyzed for physico- chemical parameters. Interview of each dairy farmers has been taken before and after the guidance to find out whether farmer got advantage of this guidelines or not. From the present investigation it has been concluded that dairy farmers were doing false practices while producing milk. They got importance of not adulterating milk and knowledge of producing milk with high quality.

Optimization of Eggshell Calcium Use for Improving the Physical Quality of Whey Protein Isolate-Based Edible Films Herly Evanuarini*, Agus Susilo, Premy Puspitawati Rahayu Animal Product Technology Department, Faculty of Animal Science, Universitas Brawijaya, Malang, Indonesia Abstract Edible films based on biopolymers are increasingly popular as environmentally friendly and functional food packaging alternatives. One approach to improving the physical properties of edible films is by incorporating calcium derived from eggshell waste. This study aims to develop and characterize edible films made from whey protein isolate (WPI) with the addition of eggshell calcium at various concentrations. The study employed a completely randomized experimental design with four treatments: the addition of eggshell calcium at 0%, 0.5%, 1.0%, and 1.5% (w/v) of the total volume of the film-forming solution, with five replicates per treatment. Characterization included measurements of thickness, water solubility, transparency, degree of swelling, moisture content, and color parameters (L*, a*, b*). ANOVA results showed that the addition of eggshell calcium had a highly significant effect (p<0.01) on solubility, thickness, transparency, degree of swelling, moisture content, and L* value in the edible film. As calcium concentration increases, film thickness and transparency values increase, accompanied by decreases in solubility and moisture content, as well as significant changes in swelling degree and color parameters. The optimal percentage is at the 1.0%-1.5% level, where the film exhibits structural stability, good transparency, and increased resistance to water solubility. The research results indicate that eggshell calcium can be utilized as a functional additive to improve the physical properties of WPI-based edible films, while also adding value to agroindustrial waste.

Acacia Honey as a Co-Substrate in Kefir Fermentation: Effects on Physicochemical Quality Firman Jaya a, Lilik Eka Radiati a, Kirana Mayang Sari b a Department of Animal Products Technology, Faculty of Animal Science, Universitas Brawijaya b Faculty of Animal Science, Universitas Brawijaya Abstract Pairing kefir with locally sourced honey may enhance product quality and support sustainable, value-added dairy innovations. The objective this study was to determine how graded Acacia honey inclusion modulates the physicochemical profile of cow^s milk kefir. Kefir was produced by inoculating cow^s milk with kefir grains (5% w/v). Acacia honey was incorporated at 0, 5, 10, 15, and 20% (v/v) and fermented for 24 h at 27-28 C, followed by refrigerated holding before evaluation. Honey addition reshaped the physicochemical profile in a dose-dependent manner. Moderate inclusion (5-10%) yielded the most favorable balance: acidification progressed as expected for kefir, while texture improved as reflected by higher viscosity. At higher levels (15-20%), the benefits plateaued or declined, indicating a trade-off between intensified acidification and texture retention. Across the inclusion range, compositional shifts were consistent with fermentation activity and dilution effects on macronutrients. Acacia honey at moderate levels optimizes the physicochemical quality of cow^s milk kefir, supporting a smooth texture and controlled acidification while maintaining practical nutrient profiles. These findings highlight a feasible route for developing locally sourced, functional dairy beverages.

Non-Destructive Assessment of Raw Milk Quality Using Computer Vision and Artificial Intelligence Ahmad Khoirul Umam (a*), Lilik Eka Radiati (a), Tri Eko Susilorini (a), and Fitri Utaminingrum (b) a) Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia b) Faculty of Computer Science, Universitas Brawijaya, Malang 65145, Indonesia Abstract This study applies computer vision and artificial intelligence (AI) to rapidly assess the quality of raw cow milk. Milk quality strongly influences processing performance and market value, with higher-grade milk commanding premium prices. To ensure consistent standards, 1008 images of raw cow milk samples were collected under controlled lighting and divided into three categories (1) good quality with normal appearance, (2) non-defective but with abnormal opacity or thickness, and (3) defective samples containing clots, sediment, or discoloration. Texture as visual biomarkers were extracted. After pre-processing and augmentation, texture features were computed using the Gray Level Co-occurrence Matrix (GLCM) with pixel distances (1, 2, 3, 4) and orientations (0, 45, 90, 135). Extracted features included contrast, correlation, homogeneity, dissimilarity, and energy. To reduce computational complexity, only the most relevant features were selected. Classification was carried out using a Decision Tree model, with the best performance at distance 3 and angle 0, yielding an accuracy of 81.68 %. Paired t-test analysis confirmed that differences across parameter variations were not statistically significant. Confusion matrix analysis further validated reliable classification across all groups. These results demonstrate the feasibility of combining GLCM-based feature extraction with Decision Tree models for non-destructive, real-time milk quality evaluation.

This study aimed to evaluate the effectiveness of enterocin as a bio-preservative in pasteurized milk at concentrations of 15 until 500 microgram/milligram by monitoring total plate count, pH, and microbial dominance during seven days of storage at 4 until 5 degrees celsius. Results indicated that the control group experienced a significant increase in pathogenic colonies (up to 1180 CFU/ml), whereas no pathogenic growth was detected in any of the enterocin-treated groups. Interestingly, microbial growth observed in the treated groups was dominated by lactic acid bacteria, which function as protective microflora. The pH of milk remained stable within the range of 6.55 until 7.07, without any sensory changes or coagulation. These findings demonstrate that enterocin not only acts as an antimicrobial agent against pathogens but also promotes beneficial LAB colonization. In conclusion, enterocin shows promising potential as a natural preservative in the pasteurized milk industry, enhancing both product safety and functional value.

Microbial Shifts in Bovine Milk Across Mastitis Severity Grades: Implications for Early Detection and Udder Health Sustainability in Tropical Dairy Systems Puguh Surjowardojo, Tri Eko Susilorini, Poespitasari Hazanah Ndaru, Rifa^i Department of Animal Science, Universitas Brawijaya, Malang, Indonesia Abstract Subclinical mastitis remains a major barrier to sustainable milk production in tropical smallholder systems due to its asymptomatic nature and microbial complexity. This study aimed to characterize the milk microbiota across progressive mastitis scores (healthy, subclinical scores 1-3) using full-length 16S rRNA sequencing via Oxford Nanopore Technology. Heatmap visualization of the top 50 most abundant taxa revealed distinct microbial patterns associated with disease severity. Streptococcus parauberis, Ralstonia pickettii, and Streptococcus agalactiae showed increasing abundance with higher mastitis scores, indicating their potential role in disease progression. Conversely, beneficial or commensal taxa such as Epilithonimonas vandammei and Lactococcus garvieae were more prevalent in healthy samples but decreased sharply as inflammation progressed. These microbial shifts underscore a dysbiotic transition in the milk microbiome associated with mastitis, providing insights into early biomarker discovery. Understanding microbial dynamics in milk offers a promising approach to enhancing mastitis diagnostics and supporting udder health management strategies, particularly in tropical dairy production systems striving for resilience and sustainability.

Impact of Good Dairy Farming Practices (GDFP) on Smallholder Dairy Farm Performance Tri Eko Susilorini(a), Muhammad Ilham Ramadhan(a), Rabbir Akbar Sanjaya(a) and Rini Dwi Wahyuni(a)* (a)Faculty of Animal Science, Universitas Brawijaya, Malang Indonesia *rinidwi_w[at]ub.ac.id Abstract This study examines the impact of Good Dairy Farming Practices (GDFP) on mastitis incidence, milk yield, milk quality, and economic outcomes for smallholder dairy farmers in Indonesia. Despite the known benefits of GDFP, its adoption remains inconsistent among small-scale operations, leading to preventable losses in productivity and income. The research aims to quantify the relationship between GDFP compliance, udder health, milk yield, and profitability across different farm scales to inform targeted interventions. A mixed-methods approach was employed, combining surveys, milk quality testing, and interviews with 59 dairy farms in Wagir Subdistrict, Malang, East Java. Farms were categorized by herd size: small (1-3 cows), medium (4-6 cows), and large (>6 cows). Data collection includes production records, milk quality testing (somatic cell counts and California Mastitis Test), and farmer interviews. Milk samples were analyzed for somatic cell counts (SCC) using Breed methods, while mastitis prevalence was assessed via the California Mastitis Test. Farmer income data were derived from production records and cooperative pricing schemes. Results demonstrated significant production differences: large farms achieved highest daily yields (66.67 liters), followed by medium (49.40 liters) and small farms (20.08 liters). GDFP implementation showed strong correlation with productivity, with large farms scoring highest (3.78/4.00) and demonstrating lowest mastitis incidence (24.3%) and SCC levels (241,000 cells/mL) versus 476,500 cells/mL in medium-scale operations. Medium farms paradoxically showed highest mastitis rates (33.8%) despite moderate GDFP adoption (3.64/4.00), suggesting management gaps in herd density control. Small farms had lower mastitis (27%) but poorest yields and GDFP implementation (3.56/4.00), reflecting limited herd size and resource constraints. Economically, GDFP-adherent farms earned 3.4 times more daily income (IDR 681,922) than smallholders, underscoring the financial viability of standardized practices. These findings highlight the critical role of GDFP in enhancing dairy farm sustainability, particularly through improved milking hygiene and animal health management. The study recommends cooperative-led training programs and subsidized inputs to bridge adoption gaps among smallholders.

Abstract This study aimed to investigate the effects of seasonal change and parity on milk production and milk composition of Taiwan Holstein Cows. The 171 complete lactation records from 68 Holstein cows, with parity 1, 2, 3, and more than 4 were used in this experiment. Data were grouped into different lactation periods and seasonal CC, CH, HH, and HC (C: Cool, H: Hot). The cool season is from November to April, while the hot season is from May to October. Traits evaluated were 305-2X-ME, daily milk yield (MY), fat %, protein %, lactose %, total solid %, somatic cell count (SCC), and somatic cell score (SCS). Results showed that season was not significantly associated with 305-2X-ME, lactose %, SCC, and SCS. However, the season had a significant effect (P<0.01) on daily milk yield, protein %, total solid% and tend to be associated (P<0.1) with fat%. The highest milk yield was observed at CH, CC for fat%, lactose% and total solid%, while HH was for protein%. In this study, parity did not significantly affect 305-2X-ME, lactose%, and total solid%. However, it showed significant affect (P< 0.01) in daily milk yield, (P<0.05) in protein and SCC.

Microclimatic Assessment of Etawah Crossbreed Goat in Trenggalek Regency, Indonesia: Insights from the Temperature Humidity Index and Heat Tolerance Coefficient Zia ul Rahman Fithron1*, Tri Eko Susilorini1, Kuswati1, and Barlian Henryranu Prasetio2 1 Department of Animal Production, Faculty of Animal Science, Universitas Brawijaya Malang, Indonesia 2 Department of Informatics Engineering, Faculty of Computer Science, Universitas Brawijaya Malang, Indonesia Abstract Heat stress is a critical challenge for goat production in tropical environments, affecting animal welfare and productivity. Etawah Crossbreed goat, widely raised in Indonesia, require evaluation of their adaptability to local microclimatic conditions. This study assessed thermal comfort in crossbreed goat using the TemperatureHumidity Index (THI) and Heat Tolerance Coefficient (HTC). Ambient temperature and relative humidity were recorded three times daily for 30 consecutive days during the dry season. Rectal temperature, respiration rate, and heart rate were simultaneously measured to calculate HTC and assess physiological responses. The average air temperature was 28.6 SD 1.2 C with relative humidity of 78.4 SD 3.1%. THI values ranged from 77.2 to 82.5, averaging 79.8 SD 1.4, indicating moderate to high heat stress. The mean HTC was 1.98 SD 0.09, reflecting moderate adaptability. Both respiration rate and heart rate increased significantly at midday when THI exceeded the comfort threshold, confirming physiological strain under heat load. Etawah crossbreed goats demonstrate adaptive capacity to tropical heat, yet prolonged exposure to elevated THI may compromise welfare and productivity. Combining THI with HTC and physiological indicators provides a practical framework for monitoring heat stress and guiding adaptive management in smallholder systems.

Improving Dairy Production in Indonesia: Comparative Lessons from India and the United States Firmansyah Tri Saputra, Puguh Surjowardojo, Tri Eko Susilorini, Muchamad Muchlas, Aswah Ridhowi, Rifai Universitas Brawijaya Abstract This study aims to illuminate the importance of high milk-producing cows and their effects on farmers and the environment. Secondary data from the annual dairy production period of 2023 to 2024 are used from the United States, India, and Indonesia. Both India and the United States are included due to their record of being top global milk producers, yet both have contrasting milk production characteristics. Subsequently, Indonesia is used as the country of interest to receive recommendations for future development. Results show that although India has the largest dairy cow population and annual milk production, the United States has the highest milk production at 33 kg milk/cow/day in both 2023 and 2024. Meanwhile, India^s daily milk production is 9 liters/cow, and Indonesia^s is around 2 liters/cow. Improving milk production per cow is recommended by various studies due to its ability to shift more nutrients toward milk production and reduce greenhouse gases. Thus, aiming national development toward high-producing cows should be prioritized.

The material used in this study consisted of 324 Joper chickens. The research was conducted using an experimental method based on a Completely Randomized Design (CRD) with a factorial pattern. The treatments applied were stocking density (9, 12, and 15 birds per square meter and the addition of zeolite in the litter (0%, 10%, and 20%) during the age of 22-56 days, resulting in 9 treatment combinations. Each treatment was replicated 3 times. Data were analyzed using ANOVA. The results of the study showed that stocking density and its interaction with zeolite supplementation had no significant effect on the blood profile of Joper chickens (P>0.05). All blood parameters, including erythrocytes, leukocytes, hematocrit, hemoglobin, MCV, MCH, and MCHC, remained within normal physiological ranges. It can be concluded that a stocking density of 15 birds per square meter with the addition of 20% zeolite was effective in not causing any negative effects on the blood profile of Joper chickens.

Goats play an important role in traditional farming systems due to their adaptability and contribution to rural livelihoods, making the documentation of local breeds essential for conservation and development programs. A total of 253 does were evaluated using direct observation, body measurements, and interviews with goat owners. The variables analyzed included population structure as well as qualitative and quantitative traits. The population in Tragah District consisted of 62 male kids (11.27%), 107 female kids (19.45%), 32 young males (5.81%), 103 young females (18.72%), 10 bucks (1.81%), and 236 does (42.90%). The mean values of quantitative traits were: withers height 67.63+4.39 cm, body length 68.71+5.08 cm, chest girth 75.38+5.82 cm, ear length 18.37+1.88 cm, and body weight 36.30+8.01 kg. Qualitative observations showed that Pote goats are predominantly characterized by a solid white coat color, relatively small body size, short pendulous ears, and straight horns. Morphometric comparisons with Kacang goats, currently the only breed with an established national standard (SNI), indicated significant differences, confirming the distinctiveness of Pote goats. These findings highlight the potential of Pote goats as a promising local genetic resource that can be further developed and conserved to support livestock diversity and farmer welfare.

Evaluation of Guazuma ulmifolia Leaf Extract in Drinking Water: Impacts on Carcass Yield and Meat Quality of Broiler Chickens Filoza Marwi, Muhammad Halim Natsir, Abdul Manab, Muhammad Diky Anam Setiawan, Salsabilla Khulaifatun Nasya, Eko Widodo Faculty of Animal Science, Universitas Brawijaya Abstract Herbal supplements are increasingly studied as natural alternatives to synthetic growth promoters in poultry production, with potential benefits for carcass yield and meat quality. Guazuma ulmifolia (GULE) has been proposed as a functional supplement, yet its impact on broiler carcass composition and meat quality remains insufficiently documented. This study evaluated the effects of GULE supplementation in drinking water on carcass traits and meat quality of broiler chickens. A total of 300 day-old MB Lohmann broilers were randomly allocated to five treatments: P0 (control), P1 (0.25% GULE), P2 (0.5% GULE), P3 (0.75% GULE), and P4 (1.0% GULE). Chickens were reared for 35 days under standardized feeding, housing, lighting, temperature, and vaccination conditions. Carcass yield, leg proportion, and back proportion were determined, and meat quality traits were assessed through dry matter, pH, tenderness, color values (L, b, and a), and water holding capacity (WHC). The results demonstrated that carcass yield and leg proportion were unaffected by treatments (p > 0.05), whereas back percentage was significantly reduced in P3 compared with P0 and P4 (p = 0.02). Meat quality was largely unchanged, with stable dry matter, pH, tenderness, L and a, and WHC values- however, yellowness (b) was significantly influenced (p = 0.02), with P1 recording the lowest values. Collectively, these findings indicate that supplementation with up to 0.75% GULE supports favorable carcass distribution and maintains meat quality, while excessive supplementation (1.0%) may induce unfavorable carcass partitioning without improving quality.

Effects of Thermal Stimulation Duration During Incubation on Organ Development and Tona Scores of Chicken Hatchlings Faizal Andri1*, Indissa Regina Nazariah1, Siti Marwiyah1, Filoza Marwi1, Ani Atul Arif1, Heni Setyo Prayogi1, Adelina Ari Hamiyanti1, Edhy Sudjarwo1, and Eric Lim Teik Chung2 1 Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia. 2 Department of Animal Science, Faculty of Agriculture, Universiti Putra Malaysia, 43400 Serdang, Selangor, Malaysia. *Corresponding author: f.andri[at]ub.ac.id Abstract Global warming and rising ambient temperatures pose a significant threat to poultry production, underscoring the urgent need for adaptive strategies. Thermal stimulation during incubation has been proposed as a method to enhance thermotolerance in chickens. However, the safe duration of thermal stimulation that maintains normal embryonic development and chick quality remains uncertain. This study evaluated the effects of different durations of thermal stimulation on organ development and Tona scores in chicken hatchlings. A total of 200 fertile eggs were randomly assigned to four treatments with five replicates of 10 eggs each. Treatments consisted of standard incubation for 21 days (T0, control) or daily thermal stimulation from embryonic day 10 to 18 for 2 hours (T1), 4 hours (T2), or 6 hours (T3). Chicks were removed from the incubator at 516 hours of incubation, and organ development and Tona scores were assessed. Results indicated that organ weight and relative percentages of the heart, liver, and gizzard were not significantly influenced by any treatment. Thermal stimulation up to 4 hours/day did not significantly affect down and appearance, retracted yolk, eyes, legs, navel area, remaining membrane, remaining yolk, or overall Tona scores. However, thermal stimulation for 6 hours/day significantly reduced the activity score. In conclusion, thermal stimulation for up to 4 hours/day during embryonic days 10 to 18 can be considered a safe threshold, whereas longer exposure may compromise chick activity. These findings provide practical insights for managing incubation practices as a potential adaptation strategy for poultry production under changing climatic conditions.

Gastrointestinal Parasitic Infections of Ruminants in Backyard Farms of Southern Isabela, Philippines Aubrey Joy M. Balbin*, Jonathan N. Nayga1, Jayson Bautista, Kevin dela Cruz, Jobelle Sapaden, Lyka Quiming, Hannah Michelle D. Catalonia, May Ann D. Fajardo, and Jamaica Bacton2 1 Cagayan Valley Small Ruminant Research Center, Isabela State University (ISU), Echague, Isabela 3309 Philippines 2 College of Agriculture, ISU, Echague, Isabela 3309 Philippines Abstract Raising of ruminant animals and trading products produced are major sources of income in rural communities in the Philippines. However, through the years, parasitic infections have remained a major challenge to productivity in livestock farming, with rising concerns on gastrointestinal parasitism. The infection can lead to economic losses due to poor animal production caused by inappetence, anemia, diarrhea, poor growth, and mortality in the herd. The study was conducted to determine the prevalent gastro-intestinal parasites in cattle and goats raised in three different municipalities located at Southern Isabela, Philippines. Fecal samples from 364 heads of cattle and 398 heads of goat raised in 10 different communities were examined to determine the most prevalent parasite and determine the degree of infestation. Floatation method of screening shows that there were 13 different gastro-intestinal parasites (GIP) identified in cattle and 11 in goat. Across all study sites, species of animal and between production stages (young, grower, and adult), Haemonchus sp. is the most prevalent gastro-intestinal parasite. The degree of infestation in cattle across the different communities in each municipality is significant (p <0.05), with fecal egg count (FEC) ranges from 298.57 to 1808.33, classified as light to heavy infection. Likewise, the FEC of samples obtained from goat was also noted to be significantly different (p <0.05), ranges from 1180.95 to 9157.14, classified as heavy infested. In consideration to the data presented, there is a widespread infestation of helminthiasis both in large and small ruminant animals causing morbidity and mortality in communities under study. The need for regular epidemiological surveillance and treatment of infected ruminants with gastrointestinal helminths is therefore recommended.

Production performance and morphometric analysis of different Boer crossbreeds Aubrey Joy M. Balbin and Jonathan N. Nayga Cagayan Valley Small Ruminant Research Center, Isabela State University, Philippines author of correspondence: aubreyjoy.m.balbin[at]isu.edu.ph Abstract Upgrading is the process of improving the genetic quality of a goat herd, facilitated by crossbreeding with superior breeds. The aim of upgrading is to enhance desirable traits such as increase meat production, higher milk yield. In this study, female animals identified as 50%Anglo-nubian (AN)-50%Native goat (Nat) served as the maternal line. A purebred Boer(B) was utilized for the production until third generation to produce F3- 87B-6.5AN-6.5N, which is considered as the terminal cross. Production data such as body weight at birth weight, weaning weight (weight at 90 days old), market weight (slaughter weight), type of birth, external body measurements (wither^s height, rump height, body length, flank girth at market weight) and coat color were gathered for analysis and animal characterization. The activity was participated by 32 farms utilizing data of 556 heads of animals. The production performance, F3 Boer crossbred group reached birth weight of 2.8 kg, weaning weight of 15.27 kg and slaughter weight of 29.1 kg. The external body measurement reveals that although F2 animals was observed to be the longest at 27 inches, F3 Boer crossbred appeared to be bulkier at 27.71-inches measurement of girth, respectively. In terms of height, F3 animals appears as the tallest 25.29 inches WH and 26.5 inches RH. The Pearson^s correlation revealed that F3 Boer crossbred goat has a positive highly significant difference WH (r=0.864**), RH (r=0.882**), FG (r=0.932**) and BL (0.956*8). Based from the result of the obtained, it can be concluded that organized upgrading can be effective method animal genetic improvement program in the rural areas.
