Abstract

The present study aimed to investigate the effect of incorporating some organic feed additives, lactose (G2), yeast (G3), lactose+yeast (G4), benzoic+citric acid (G5), lactose+benzoic+citric acid (G6) and diet prepared without additives (G1), on performances and immune status of one-week-old growing Japanese quails in 35 days growth performance trial. Chicks were randomly divided into 6 groups (30 birds each; mean weight 30.5g), each was subdivided into 3 replicates (10 chicks each). Body weight (BW), body weight gain (BWG), feed intake, feed conversion ratio and feed efficiency were determined weekly. At the end of the growing trial, 36 birds (2birds/replicate) were slaughtered for determination of carcass traits, and the economic efficiency. Blood samples were collected for measuring some serum biochemical parameters and immunoglobulin M (IgM). The results showed that the BW increased significantly in G2 and G6 compared to control (G1). The BWG was significantly higher in all treatme

Conclusion

In conclusion the present study showed that, 0.3% yeast, 0.1% lactose and OAC or OAC with lactose improved the growth performance, immune response and reduced cost of production and relative economic efficiency especially due to 0.1% lactose and OAC with lactose.
