中草药添加剂对獭兔母兔泌乳力的影响

试验旨在研究日粮添加不同水平的中草药添加剂对母兔泌乳力影响。选取99只体重相近、胎次相同的母獭兔，随机分为3组，每组33只，分别饲喂基础日粮、基础日粮+1%中草药添加剂和基础日粮+2%中草药添加剂。预试期4 d，正试期26 d（分娩后第0天至下一次配种前1天）。检测其产仔性能及分娩第0、7、14、21和28天的泌乳量。试验结果表明，饲喂2%中草药添加剂的母兔产后不同时间泌乳量极显著（P<0.01）或显著（P<0.05）高于对照组；1%添加剂组母兔泌乳量与对照组相比有增加趋势，但差异不显著（P>0.05）；随着中草药添加量的增加，仔兔断奶成活率逐渐提高，但差异不显著（P>0.05）。综合以上试验结果，中草药添加剂有提高母兔泌乳力及仔兔断奶成活率的效果，以添加量为2%为宜。

Effect of Chinese Herbal Medicine Additives on Milk Production of Rex Rabbit

This study was designed to explore the effect of Chinese herbal medicine additives on milk production and reproduction performance of rabbit does. Total 99 does were separated into 3 treatments (33 does in each treatment) and fed with the basal diet adding 0, 1%, 2% Chinese herbal medicine additives,respectively. Pre-feeding period was 4 d and test period was 26 d (from the first day of postpartum to the last day before next mating). Daily milk production of does was detected after delivery 0, 7, 14, 21 and 28 d. Both litter size and the number of weaned rabbits were recorded. The results showed that milk production of does fed with 2% Chinese herbal medicine additives were increased extremely significantly (P<0.01) or significantly (P<0.05) compared to control group, and there was no significant difference between control group and 1% Chinese herbal medicine additives group (P>0.05). Survival rate of weaned rabbits increased with the increasing dosage of the additives, but did not differ significantly (P>0.05). In conclusion, the Chinese herbal medicine additives could improve milk production of rabbit does and survival rate of weaned rabbits, and the optimal dosage should be 2%.
