低聚木糖对生长猪免疫功能和血液生化指标的影响

选择体重20 kg左右的杜枫姜三元杂交猪180头,随机分成4组,每组45头.4个组分别饲喂基础日粮(对照组)、基础日粮+100 mg·kg~(-1)低聚木糖(1组)、基础日粮+150 mg·kg~(-1)低聚木糖(2组)、基础日粮+200 mg·kg~(-1)低聚木糖(3组),探讨不同处理对生长猪免疫功能和血液生化指标的影响.结果表明:与对照组相比,试验1～3组血液单核细胞数分别增加10.7%、37.5%、1.8%;试验组血小板数有提高趋势,且2组显著高于对照组;试验组血清碱性磷酸酶活性比对照组分别提高31.1%、17.2%、33.3%;试验组血清溶菌酶活性也有提高趋势(P>0.05);试验组血清谷草转氨酶活性和葡萄糖含量均高于对照组,但差异不显著;试验组血清尿素氮含量有下降趋势(P>0.05);1、3组血清胆固醇含量显著低于对照组,2组血清胆固醇含量极显著低于对照组.

Effects of dietary xylooligosaccharide on immunity and serum biochemical index of growing pigs

180 crossbred growing pigs with body weight of 20 kg were randomly allocated to four groups,45 pigs per group.The pigs were fed with basic diet,basic diet plus 100 mg·kg~1 xylooligosaccharide,basic diet plus 150 mg·kg~(-1)xylooligosaccharide,basic diet plus 200 mg·kg~(-1) xylooligosaccharide respectively to study the effects of xylooligosaccharide on immunity and serum biochemical index of growing pigs.The results showed that:the serum monocyte in treatment groups was increased by 10.7%,37.5%,1.8% respectively compared to the control group;the xylooligosaccharide had the trend of improving the serum haematoblast,and the haematoblast of group 3 was significant higher than control group;the activity of serum alkaline phosphatase in treatment groups was increased by 31.1%,17.2%,33.3% respectively compared to the control group;and the activity of serum lysozyme was increased by the supplementation of xylooligosaccharide,but had no significant difference;the xylooligosaccharide had the trend of improving the activity of serum aspartate aminotransferase,the quantity of glucose and decreasing the serum urea nitrogen;the quantity of serum cholesterol in group 2,4 was significantly lower than control group,the quantity of serum cholesterol in group 1 was significantly lower than control group.
