【摘要】：为研究谷朊粉酶解物对断奶仔猪血清生化指标、免疫功能及小肠发育的影响,选取108头平均体重(8.08±0.36)kg的杜×长×大三元杂交仔猪,按体重相近原则随机分为4个处理,每处理3个重复,每个重复9头猪,各处理组分别饲喂基础日粮(对照组)添加血浆蛋白粉日粮添加1.5%和3.0%谷朊粉酶解物日粮,饲喂期21 d。结果表明,(1)添加1.5%谷朊粉酶解物组的血清总蛋白和球蛋白均高于其他3组;(2)断奶第21天,添加谷朊粉酶解物组血清GSH-Px和SOD的活性明显高于对照组和血浆蛋白粉组;(3)断奶第21天,对照组和血浆蛋白粉组血清T3的含量均显著高于3.0%谷朊粉酶解物组,分别高12.4%和12.1%,而血浆蛋白粉组血清IGF-1含量显著高于其他3组;(4)断奶第10天,添加1.5%谷朊粉酶解物组血清lg A的含量显著高于其他3组;(5)断奶第21天,添加1.5%谷朊粉酶解物组的十二指肠绒毛高度最长,分别比对照组和血浆蛋白粉组长29.0%和21.4%,而隐窝深度相反,分别比对照组和血浆蛋白粉组短21.1%和23.8%。
[Abstract]:In order to study the effect of gluten enzymatic hydrolysis on serum biochemical indexes, immune function and small intestine development of weaned piglets, 108 脳 10 8 脳 long 脳 3 D crossbred piglets with average body weight (8. 08 卤0. 36) kg were selected. According to the principle of similar body weight, were randomly divided into 4 treatments, each treatment 3 repeat, each repeat 9 pigs, each treatment group were fed with basal diet (control group). Added plasma protein meal diet? The diets supplemented with 1.5% and 3.0% gluten hydrolysate were fed for 21 days. The results showed that: (1) the serum total protein and globulin of the group supplemented with 1.5% gluten hydrolysate were higher than those of the other three groups; (2) on the 21st day after weaning, the activities of serum GSH-Px and SOD in the gluten hydrolysate group were significantly higher than those in the control group and the plasma protein powder group; (3) on the 21st day after weaning, the serum T3 levels in the control group and the plasma protein powder group were significantly higher than those in the 3.0% gluten enzymatic hydrolysis group, which were 12.4% and 12.1% higher than those in the control group and plasma protein powder group, respectively. The serum IGF-1 level in the plasma protein powder group was significantly higher than that in the other three groups. (4) on the 10th day of weaning, the content of serum lg A in the group supplemented with 1.5% gluten was significantly higher than that in the other three groups. (5) on the 21st day of weaning, the height of duodenal villi in the group supplemented with 1.5% gluten enzymatic hydrolysis was the longest, which was 29.0% and 21.4% respectively than that of the control group and the plasma protein powder group, but the depth of the crypt was opposite. It was 21. 1% and 23. 8% shorter than the control group and the plasma protein powder group, respectively.
