繁殖獭兔饲料配方的筛选研究

Study of Selecting Feed Formulation of the Rex Rabbit Doe

试验选用32只同期配种的种母兔,随机分为4组,每组8只。日粮采用不同的牧草组合分别为青干草、青干草+苜蓿、青干草+花生秧、青干草+苜蓿+花生秧,即分别为试验Ⅰ组、Ⅱ组、Ⅲ组和Ⅳ组。测定獭兔的产仔数、产活仔数、初生窝重、断奶窝重、21日龄窝重、断奶成活率等繁殖性能指标。结果表明:试验Ⅳ组的断奶成活率显著的高于试验Ⅰ组、Ⅱ组(P<0.05),但与试验Ⅲ组间的差异不大(P>0.05),试验Ⅰ组、Ⅱ组、Ⅲ组之间的差异不显著(P>0.05)。另外,试验Ⅱ组的断奶个体重显著性的高于其它三个试验组(P<0.05),分别高出7.45%、9.34%、6.93%,其它三个试验组的差异不显著(P>0.05)。各组之间的产仔数、产活仔数、断奶仔兔数、初生窝重、断奶窝重、初生个体重、21日龄窝重差异不显著(P>0.05)。经分析比较,当饲草资源不足时,饲草组合为青干草+花生秧的日粮较符合生产的需要。

Thirty-two does were used as experimental animals,which were allocated at random to 4 groups of eighty each.Different dietary respectively include hay,hay ＋ alfalfa,hay ＋ peanut vine,hay ＋ alfalfa ＋ peanut vine（groupⅠ、groupⅡ、groupⅢ and groupⅣ）.The trial was aimed to measure the indexes of reproductive performance such as number born、number born alive、litter weight at birth、weaning weight of litter、litter weight at 21 days、weaning survival rate.The results showed that： the weaning survival rate of group Ⅳwas significantly higher than the group Ⅰand Ⅱ（P 0.05）,with no significant difference with the group Ⅲ（P 0.05）.Meanwhile the difference between the groupⅠ、Ⅱand Ⅲ was also no noticeable（P0.05）.In addition,the individual weaned weight of group Ⅱwas significantly higher than other three groups（P0.05）,respectively 9.34%,6.93%,7.45%,with no significant difference between other three groups（P0.05）.The differences were not significant between groups,such as number at born,number born alive、weaned number、litter weight at birth、weaning weight of litter、the individual born weight、litter weight at 21 days（P0.05）.By comparison,when the roughage is deficiency,the diet including hay ＋ peanut vine is feasible.
