摘　　要：本试验旨在研究谷子替代玉米对母兔繁殖性能及血清生殖激素、生化、免疫和抗氧化指标的影响。选用180只体重和胎次相近、健康状况良好的伊拉母兔为研究对象,按照体重对等原则,随机分为6组,每组30个重复,每组30只,单笼饲养。对照组(CN组)饲喂基础饲粮,试验组分别饲喂使用5%(HY5%组)、10%(HY10%组)、15%(HY15%组)、20%(HY20%组)和25%(HY25%组)谷子替代基础饲粮中部分玉米的试验饲粮。预试期7 d,正试期70 d。结果显示:1)与CN组相比,HY15%、HY20%和HY25%组的断奶窝重显著提高(P<0.05),HY15%组的断奶活仔数显著提高(P<0.05)。2)与CN组相比,HY15%和HY20%组哺乳第21天时血清催乳素含量显著提高(P<0.05)。3)与CN组相比,HY15%和HY20%组哺乳第21天时血清总蛋白含量显著提高(P<0.05)。4)与CN组相比,HY10%、HY15%、HY20%和HY25%组哺乳第35天时血清超氧化物歧化酶含量显著提高(P<0.05)。综上所述,综合考量母兔的繁殖性能及血清生殖激素、生化、免疫和抗氧化指标,谷子替代玉米对母兔无负面影响,说明谷子可以用作母兔的能量饲料;母兔饲粮中用谷子替代部分玉米可以促进催乳素的分泌,提高仔兔的断奶窝重,并能提高机体的抗氧化能力。本试验条件下,以15%的谷子使用量效果最佳。The aim of this experiment was to study the effects of partial replacement of corn by millet on reproductive performance,serum reproductive hormones,biochemical,immune and antioxidant indexes of female rabbits.A total of 180 Ira female rabbits with similar body weight and parity(3 to 5 parities)and good health were randomly divided into 6 groups according to the principle of weight equivalence,with 30 rabbits in each group,and each rabbit fed in a single cage.The rabbits in the control group(CN group)were fed a basal diet,and others in the experimental groups were fed experimental diets in which 5%(HY5% group),10%(HY10% group),15%(HY15% group),20%(HY20% group)and 25%(HY25% group)millet were used to replace some corn in the basal diet,respectively.The pretest period was 7 days and the formal period was 70 days.The results showed as follows:1)compared with the CN group,the weaning weight of litter in the HY15%,HY20%and HY25%groups was significantly increased(P<0.05),the number of weaned litters in the HY15%group was significantly increased(P<0.05).2)Compared with the CN group,serum prolactin content was significantly increased at day 21 of lactation in the HY15% and HY20% groups(P<0.05).3)Compared with the CN group,the serum total protein content at day 21 of lactation in the HY15% and HY20% groups was significantly increased(P<0.05).4)Compared with the CN group,the superoxide dismutase content in serum of the HY10%,HY15%,HY20% and HY25% groups was significantly increased at day 35 of lactation(P<0.05).In conclusion,considering the reproductive performance,serum reproductive hormones,biochemical,immune and antioxidant indexes of female rabbits,the partial replacement of corn by millet has no negative effect on female rabbits,indicating that millet can be used as energy feed for female rabbits;replacing part of corn with millet in the diet of female rabbits can promote the secretion of prolactin,increase the weaning litter weight of young rabbits,and enhance the antioxidant capacity of the body.Under the conditions
