ABSTRACT
This research aims to determine the best level of red onion skin extract (ROSE) as a replacement for synthetic antibiotic growth promoter (AGP) in the diet of laying quails. The laying quails (n=180) used in this study were 44 weeks old, with an average production of 55%. The experiment followed a completely randomized design, with three treatments: A (basal diet + Zinc bacitracin), B (basal diet + 1% ROSE), and C (basal diet + 2% ROSE). Each treatment was replicated six times. The observed variables were the Escherichia coli count of the intestine and the performance of laying quails (feed consumption, egg production, egg weight, egg mass, and feed conversion). The results showed that the inclusion of ROSE in the diet significantly (p<0.05) reduced the Escherichia coli population in the intestine as compared to the control group (group A). However, ROSE inclusion in the diet of laying quails had no (p>0.05) effect on the performance parameters. Therefore, 1 to 2% ROSE in the diet of laying quails can be used to replace with synthetic AGP.
