Reproductive and hormonal responses of two breeds of roosters fed diets containing chromium picolinate with or without vitamin C at high ambient temperature

This study evaluated the effects of chromium picolinate (CrPic) with or without vitamin C on reproductive potentials cocks raised under high ambient temperature. Four diets contained CrPic at 0.00 to 1.20 mg kg-1 and another four 200 each. A total 192 White Leghorn Noiler (96 each) were randomly assigned 8 treatments replicated 4 times 6 per replicate in a 2 x2 x factorial experiment. At end sixteen weeks study, twelve birds treatment sacrificed. The testes carefully sampled, weighed processed for estimation daily sperm production using homogenate method. results revealed that interactions 0.40 significantly (p < 0.05) influenced gonadal extra-gonadal weights, semen characteristics among while hormones not negatively affected. therefore, concluded diet could reduce heat stress temperature impacting their normal functions.
