中文摘要：

为了探讨液体营养素对断奶华南土黑仔猪生产性能和健康水平的影响。试验选取160头断奶仔猪,随机分成4组,分别饲喂基础日粮（对照A组）、基础日粮＋新胺基维他0.8 mL/头（B组）、基础日粮＋新胺基维他1 mL/头（C组）,基础日粮＋新胺基维他1.2 mL/头（D组）。结果表明：（1）与对照A组相比,B组、C组和D组仔猪的末重、日增重和日采食量均显著提高（P〈0.05）;B组、C组和D组仔猪的料重比显著降低（P〈0.05）。（2）与对照A组相比,B组仔猪腹泻率下降13.33%,C组下降16.9%,D组下降15.01%;B组与D组仔猪死亡率下降5%,C组下降7.5%。结果表明：在本试验条件下在饲粮中添加新胺基维他1 mL/头为最佳浓度,其对断奶仔猪有明显的促生长作用。

英文摘要：

In order to investigate the liquid nutrients effected on production performance of weaning black piglets in Southern China. 160 pigs weaning piglets were randomly divided into 4 groups, which were fed on the basis diet （control group A）, basis diet ＋ XinAnJiWeiTa 0.8 mL/A PIG （group B）, basis diet ＋ XinAnJiWeiTa 1 mL/A PIG （group C）, basis diet ＋ XinAnJiWeiTa 1.2 mL/A PIG （group D）. The results showed that： （1）Compared with the A group, Final Weight, Daily Weight Gain and Daily Feed Intake of B group, C group and D group piglets were significantly increased （P〈0.05）;Feed to Gain Ratio of B group, C group and D group were significantly decreased（P〈0.05）. （2）Compared with the control group A, Diarrhea Rate of group B piglet decreased by 13.33%, Diarrhea Rate of group C decreased by 16.9% , Diarrhea Rate of D group decreased by15.01%; Mortality of B group and D group were decreased by 5%, Mortality of C group decreased by 7.5% .In conclusion,it had the best effects on performance and immunity of weaning piglets by added XinAnJiWeiTa 1 mL/A PIG （group C）,XinAnJiWeiTa had obvious effects on performance and immunity of weaning piglets.
