Abstract
Insects exctrac and hydrolisate are known to contain many bioactive peptides with antibacterial, antiparasitic, and antiprotozoal properties. The purpose of this study was to determine the influence of extract and hydrolysate protein from brown cricket (Gryllus assimilis) on the production performance of quails as antibiotic. A total of 400 female quails aged 6 weeks were reared and fed, watered and vaccinated according to recommendations in colony cages for 30 days. They were separated into four treatments with five replications, each with twenty quails. P0 = basal feed, P1 = basal feed with antibiotic 5 mg/kg, P2 = basal feed with insect extract 6 mg/kg, P3 = basal feed with insect hydrolysate protein 6 mg/kg. The administration of exctract and hydrolysate protein was carried out through feed. The variables measured were productivity (feed consumption, egg weight, feed conversion, cholesterol) quality of quail eggs (egg shell weight and thickness) and body resistance (white blood cell). The result show that the total cholesterol of egg yolks of P3 treatment was lower than the control. Administration of hydrolysate protein in P3 treatment increased the leukocyte value of quail compared to the control treatment . Administration of hydrolysate protein in P3 treatment increased the leukocyte value of quail compared to the control treatment (6.00 from 4.00, respectively). Although it did not have a significant influence on feed consumption, egg weight and feed conversion. In conclusion, applying hydrolysate protein of insect in feed can be utilized as a feed additive and as an alternative to antibiotics.
