【摘要】：本试验旨在研究豆粕中大分子蛋白质和肽含量对仔猪小肠绒毛结构的影响。采用凝胶过滤色谱技术分析豆粕中大分子蛋白质和肽含量。选取40头断奶仔猪,随机分成4个处理:去皮豆粕处理、发酵豆粕C处理、发酵豆粕E处理和动物蛋白处理。试验期5周。结果表明:去皮豆粕中大分子蛋白质含量约占80%,发酵豆粕中约占50%,甚至降至24%;发酵豆粕中肽含量约占19%,去皮豆粕中仅有2.7%。与去皮豆粕处理相比,发酵豆粕C处理十二指肠绒毛高度显著提高(P0.05),发酵豆粕E、发酵豆粕C处理十二指肠、空肠隐窝深度显著下降(P0.05),发酵豆粕E、发酵豆粕C处理十二指肠和空肠的绒毛高度/隐窝深度均显著升高(P0.05)。由此可见,豆粕中大分子蛋白质含量与小肠绒毛高度/隐窝深度呈负相关;发酵豆粕能够在断奶仔猪饲料中使用,并且有效改善断奶仔猪小肠绒毛结构。
[Abstract]:The purpose of this study was to study the effects of macromolecular protein and peptide content in soybean meal on the villus structure of piglets. The content of macromolecular protein and peptide in soybean meal was analyzed by gel filtration chromatography. Forty weaned piglets were randomly divided into four treatments: peeled soybean meal treatment, fermented soybean meal C treatment, fermented soybean meal E treatment and animal protein treatment. The trial period was 5 weeks. The results showed that the content of macromolecular protein in peeled soybean meal was about 80%, and that in fermented soybean meal was about 50%, even down to 240.The content of peptide in fermented soybean meal was about 19%, and only 2.7% in peeled soybean meal. Compared with peeled soybean meal treatment, the height of duodenum villi of fermented soybean meal C was significantly increased (P0.05), fermentation soybean meal E, fermented soybean meal C treatment duodenum, Jejunal crypt depth decreased significantly (P0.05), fermentation soybean meal E, fermented soybean meal C treatment duodenum and jejunum villi height / crypt depth significantly increased (P0.05). It can be seen that the content of macromolecular protein in soybean meal is negatively correlated with villi height / crypt depth, and fermented soybean meal can be used in weaning piglets and improve the structure of small intestinal villi of weaned piglets.
