Abstract: 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.
