Abstract:   (740 Views)
The present study was conducted to evaluate the efficacy of organic acids combination on performance, blood biochemical parameters, intestinal morphology and internal egg quality parameters of layer Japanese quails in completely randomized design manner using 225 layer quails in 3 treatments, 5 replicates and 15 quails in each replicate, reared for two periods of 3 weeks each (37-39 and 40-42 weeks). Treatments were: 1) control; 2) basal diet with 0.04% AGP (bacitracin dimethyl salicylate) and 3) basal diet with 0.01% of organic acids combination. Results showed that feed consumption, egg production, egg weight and egg shell percentage were increased significantly compared to the control group by incorporating organic acids combination into the diet. Also significant increase the intestinal villus height, number of goblet cells and intestinal crypt depth were observed in the organic acids supplemented group. The lowest concentration of calcium, high-density lipoprotein, serum levels of alkaline phosphatase, feed conversion ratio and Haugh unit scores were found in organic acids fed quails. Glucose, total protein, phosphorus and serum aspartate aminotransferase values were not affected significantly by the experimental groups. Based on the results of this study, application of organic acids combination as a viable alternative to antibiotic growth promoters can be recommended in layer Japanese quails egg.
