Study was undertaken to evaluate the effects of supplementing organic zinc and chromium (Cr) on semen quality in layer breeders. Forty Dahlem Red roosters of 22 weeks age were distributed into four groups and diet was supplemented with organic Cr at graded levels (0, 0.3, 0.6, 0.9 mg/kg) for twelve weeks duration. Semen collected at 4th and 8th week of experiment was analysed for different gross parameters and seminal plasma lipid peroxidation. A four week fertility trial was conducted with fixed dose semen insemination (100 million sperm in 0.1ml) every week. In another experiment, thirty two adult Dahlem Red roosters divided into four groups were supplemented with organic zinc (0, 40, 70 and 100 mg/kg diet) for eight weeks. Semen was collected and evaluated for different gross parameters, superoxide dismutase activity and lipid peroxidation at 4th and 8th week of experiment. Sperm was evaluated for nuclear maturity at eighth week of experiment. Roosters supplemented with organic zinc 100 mg/kg diet produced significantly (P < 0.05) higher MTT formazan indicating higher metabolic activity of sperm. Zinc supplementation had no effect on any other parameters studied. Significant difference (P < 0.05) between weeks of experiment in appearance, live and abnormal sperm was observed. Supplemental Cr did not affect semen parameters, fertility or hatchability. In conclusion, organic Cr supplementation did not improve semen quality, fertility and hatchability in layer breeders and supplementation of organic zinc at 100 mg/kg improved sperm metabolic activity.
