Abstract
The study was conducted to evaluate the effect of probiotic diet supplementation on som e 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 T3 levels in (2nd and 3rd group) as compared with control group at p <0.05. Also the probiotic treatment causes a significan t 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.
