摘　　要：试验旨在研究益生菌发酵中草药制剂对猪生长性能及猪肉品质的影响,选择30~40 d断奶仔猪30头分三组进行饲喂,每组10头,试验Ⅰ组于基础饲粮中添加0.2%益生菌发酵中草药制剂,试验Ⅱ组于基础饲粮中添加0.4%益生菌发酵中草药制剂,对照组饲喂基础饲粮。试验周期160 d。结果表明,添加益生菌发酵中草药制剂可以显著提高猪平均日增重(P<0.05),平均日采食量有所下降但差异不显著(P>0.05),料重比、腹泻率、便秘率显著下降(P<0.05)。屠宰后对猪肉品质进行检测,发现三组猪肉色、pH与猪肉剪切力差异均不显著(P>0.05)。试验Ⅰ组与试验Ⅱ组猪肉大理石纹评分显著高于对照组猪肉(P<0.05),试验Ⅰ组与试验Ⅱ组猪肉滴水损失显著低于对照组(P<0.05)。与对照组相比,试验Ⅱ组猪肉胆固醇含量显著降低(P<0.05)、肌内脂肪含量显著提高(P<0.05);试验组猪肉中肉豆蔻酸、棕榈酸含量显著降低(P<0.05),硬脂酸、十七烷酸、棕榈油酸、油酸、亚油酸、花生四烯酸含量显著提高(P<0.05),正癸酸、月桂酸、银杏酸、二十碳一烯酸含量差异不显著(P>0.05)。以上结果表明,该制剂可以提高猪的生长速度,降低料重比,提高饲料利用率,改善猪群健康状况,提高猪肉品质。The purpose of this experiment was to study the effects of probiotic fermented Chinese herbal 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 groupsⅠandⅡrespectively,and the control group was fed the basic diet.The test period lasted for 160 days.The results showed that the addition 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 experimental 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-decanoic 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.
