摘要
该试验将日龄、体重(9.00±0.25 kg)接近的健康的杜×长×大三元杂交断奶仔猪60头,随机分成4组,每组3个重复,每个重复 5 头仔猪,对照组饲喂基础日粮,试验Ⅰ组到Ⅲ组分别饲喂含有 0.3%、0.6%、0.9%党参多糖的基础日粮.结果显示:与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组断奶仔猪末重、平均日增重和平均日采食量均显著提高(P<0.05);试验Ⅰ、Ⅱ、Ⅲ组断奶仔猪的料重比均显著降低(P<0.05).与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组断奶仔猪血清中的总蛋白、球蛋白和碱性磷酸酶的含量均显著提高(P<0.05);试验Ⅰ、Ⅱ、Ⅲ组断奶仔猪血清中的谷草转氨酶、谷丙转氨酶、尿素氮和肌酐的含量有所提升,但差异不显著(P>0.05).与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组断奶仔猪血清中的免疫球蛋白G含量均显著提高(P<0.05).可见,党参多糖可改善断奶仔猪免疫能力和生长性能,在日粮中添加0.9%党参多糖效果较好.
Abstract
In this experiment,60 healthy Duroc×Landrace×Yorkshire weaned piglets with similar age and body weight(9.00±0.25 kg)were randomly divided into 4 groups with 3 replicates in each group and 5 piglets in each replicate.The control group was fed with a basal diet and the experimental groups Ⅰ to Ⅲ were fed with a basal diet supplemented with 0.3%,0.6%,and 0.9%ginseng polysaccharide,respectively.The results showed that compared with the control group,the final weight,average daily gain,and average daily feed intake of weaned piglets in groups Ⅰ,Ⅱ,and Ⅲ were significantly increased(P<0.05).The feed-to-weight ratio of weaned piglets in groups Ⅰ,Ⅱ,and Ⅲ was significantly decreased(P<0.05).Compared with the control group,the contents of total protein,globulin and alkaline phosphatase in the serum of weaned piglets in groups Ⅰ,Ⅱ,and Ⅲ were significantly increased(P<0.05).The contents of aspartate aminotransferase,alanine aminotransferase,urea nitrogen and creatinine in the serum of weaned piglets in groups Ⅰ,Ⅱ,and Ⅲ were increased,but the difference was not significant(P>0.05).Compared with the control group,the IgG content in the serum of weaned piglets in groups Ⅰ,Ⅱ,and Ⅲ was significantly increased(P<0.05).It can be seen that ginseng polysaccharide can improve the immunity and growth performance of weaned piglets,and the effect of adding 0.9%ginseng polysaccharide e to the diet is better.
