Effects of Probiotic-fermented Herbal Medicine Preparation on Growth Performance of Pigs and Quality of Pork
The purpose of this experiment was to study the effects of probiotic fermented Chinese herb-al medicine preparation on growth performance and pork quality.Thirty piglets weaned at 30～40 days were divided into three groups,with 10 piglets in each group.0.2％and 0.4％probiotic fermented Chinese herbal medicine preparation were added to the basal diets of test groups Ⅰ and Ⅱ respectively,and the control group was fed the basic diet.The test period lasted for 160 days.The results showed that the addi-tion of probiotics fermented Chinese herbal medicine preparation could significantly increase the average daily gain of pigs(P＜0.05),the average daily feed intake decreased but with insignificant difference(P＞0.05).The feed-to-weight ratio,diarrhea rate and constipation rate all decreased significantly(P＜0.05).The pork quality after slaughter showed that there was no significant difference in pork color,pH and shear force between the three groups(P＞0.05).The marbling scores of pork in test group Ⅰ and test group Ⅱ were significantly higher than that in control group(P＜0.05).The drip loss of pork in group Ⅰ and group Ⅱ was significantly lower than that in the control group(P＜0.05).The cholesterol content in group Ⅱ decreased significantly(P＜0.05)and the intramuscular fat content increased significantly(P＜0.05)compared with the control group.The contents of myristic acid and palmitic acid in pork in the experi-mental group significantly decreased(P＜0.05),while the contents of stearic acid,heptadecanoic acid,palmitoleic acid,oleic acid,linoleic acid and arachidonic acid significantly increased(P＜0.05).The contents of n-de-canoic acid,lauric acid,ginkgo acid and eicosapentaenoic acid were not significantly different(P＞0.05).The results show that the preparation can improve the growth rate of pigs,reduce the feed-wight ratio,improve the utilization rate of feed,the health status of pigs as well as the quality of pork.
