Effect of Fresh Feed and Mixed Feed on Reproductive Performance in Coffee Mink During the Breeding Period
摘要
Abstract
This study was to evaluate the effect of fresh feed and mixed feed on the reproductive performance in the mink during the breeding period.This experiment selected 4 957 healthy female minks which were randomly divided into 2 groups, fresh feed group (FG) 4 907, the mixed feed group (MG) 50, and MG including 50% fresh feed and 50% mixture with 1.7 times water and 1 times pellet feed.The experiment was 6 days for adaption and 135 days for trial period.The results showed as follows:1) Oestrus detection of female mink was influenced by FG and MG, the proportion of general estrus 16.67% in MG was higher than that 6.67% in FG.The proportion of no estrus 0% in MG was lower than that 10% in FG.The proportion of good estrus was the same 83.33% in FG and MG.2) Mate times of male mink was influenced by FG and MG, lowest mate times of male mink in MG was 9 times higher than that 4 times in FG.Average mate times in MG was higher12.5% than that 11.64% in FG. Mate ratio of male and female was 1:5 higher in MG than that 1:3.94 in FG, but the utilization rate 100%and the highest mate times (17 times) of male mink were the same in two groups.3) Mate performance of female mink was influenced by FG and MG. Mate rate of female mink in MG was 100% higher than that 98.64% in FG. The proportion of mate 3 times was higher 38% in MG than that 2.90% in FG. The proportion of mate 2 times was lower 56% in MG than that 93.78% in FG. The proportion of mate 1 times was higher (6%) in MG than that 3.32% in FG.4) Farrowing performance of female mink was influenced in two groups. Farrowing rate in MG was higher 100% than that 94.56% in FG. Fetal average litter size in MG was higher 6.64 than that 6.03 in FG.The proportion of no pregnancy in MG 0% was lower than that 5.22% in FG. The proportion of no litter in MG was higher 4.00% than that 3.01% in FG. Average breed number in MG was higher 6.56 than that 5.59 in FG. No significant difference (P> 0.05) on average body weight of 30-days old kits and average body weight of 45-days old kits in two groups, but average body weight of 30-days old kits and 45-days old kits in MG were slightly higher than that in FG. Based on the above analysis, compared with FG, MG promotes the oestrus and breeding and is advantageous to promote sufficient milk secretion of female mink, as well as improves the growth of the young mink. Therefore, this feeding mode is feasible in mink farming production.关键词
