| Popis: | Background: Interaction between nutrition and reproduction has been established to play an important role in reproductive performance of animals. Zinc is considered to be an essential element required for reproduction. The present study was conducted to evaluate the efficiency of nano zinc (NZn) as feed supplementation on reproductive performance of Assam Hill goats. Methods: A total of twenty-four numbers of 7 days post kidding doe maintained at Goat Research Station, Assam Agricultural University, Burnihat were randomly selected and divided into 4 groups comprising 6 animals in each group. The control group animals were fed with basal diet without zinc supplementation however, all the animals of the treatment groups received 25 mg NZn, 35 mg NZn and 50 mg NZn/kg concentrate mixture with basal diet for a period of three months. Does were bred naturally at 24 hours from the onset of oestrus and confirmed for pregnancy after two months. Parturition behaviour was observed closely from two days before the expected date of kidding upto the period of placental expulsion. Result: Supplementation of 50 mg NZn to the basal diet of postpartum Assam Hill Goat significantly improved the reproductive performance by decreasing postpartum oestrus interval and increasing conception rate (83.33%). |
