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

摘要

The aim of this tria1 was to study the effects of wheat g1uten enzyme hydro1ysate (WGEH) on the serum biochemi-ca1 index, immunity and intestine deve1opment. 108 crossbred Duroc× Landrace× Largewhite wean1ing pig1ets with body weight (8.08 ± 0.36)kg were random1y a11ocated to 4 treatments and fed with basa1 diet (contro1 group),p1asma protein diet,1.5%and 3% WGEH diet for 21 days,respective1y. Each treatment had 3 rep1icates and each rep1icate had 9 pig1ets. The resu1ts showed that:(1)Serum tota1 protein and g1obu1in of 1.5% WGEH diet group were higher than the other 3 groups,but the dif-ference was not significant;(2)After weaned 21 days, serum GSH-Px and SOD activity of WGEH diets groups were signifi-cant1y higher than contro1 group and p1asma protein group;(3) Content of serum T3 of contro1 group and p1asma protein group was significant1y higher than that of 3% WGEH group by 12.4% and 12.1% after weaned 21 days,whi1e IGF-1 of p1asma protein group was significant1y higher than the other 3 groups;(4)Serum 1gA of 1.5%WGEH group was significant1y higher than the other 3 groups in 10 days after weaned;(5)After 21 days of weaned, duodenum vi11us height of 1.5%WGEH group was the 1ongest, which was higher than contro1 group and p1asma protein group by 29.0% and 21.4%(P<0.05), respective1y. But the crypt depth was contrast, it was 1ower than contro1 group and p1asma protein group by 21.1% and 23.8% (P<0.05),respective1y.%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1gA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%。
