Effect of probiotic on some physiological parameters in broiler breeders

Abstract

The study was conducted to evaluate the effect of probiotic diet supplementation on some physiological parameters in Broiler Breeders. 30 Cobb Breeder hens were used (46 week aged), divided into 3 groups (10 hens each). The 1st group was reared on standard ration (control), the 2nd and the 3rd groups were given 10 and 20 gm of probiotic/kg ration for 4 weeks. The results revealed that the probiotic treatment causes a significant increase in LH and FSH serum levels (3rd group) and in T 3 levels in (2nd and 3rd group) as compared with control group at p<0.05. Also the probiotic treatment causes a significant decrease in serum triglyceride levels and a significant increase in serum Uric acid level as compared with control. The above effects reflected in improvement of the egg weight, yolk weight and egg production % as compared with control. In conclusion, the probiotic supplementation of Broiler Breeders diet will improve the hormonal status and enhance the productivity. © Asian Network for Scientific Information, 2011.
