摘要
本试验研究了含肽肝素渣水解物对早期断奶仔猪十二指肠食糜淀粉酶、脂肪酶和胰蛋白酶活性以及小肠绒毛高度和隐窝深度的影响。结果显示,饲喂肝素渣水解产生的寡肽后,早期断奶仔猪十二指肠食糜中消化酶的活性升高,小肠绒毛高度增加,隐窝深度降低。本研究为含肽肝素渣的合理利用提供了新的思路。
The experiment was conducted to investigate the effect of porcine intestine hydrolysate on the histological and enzymatic characteristic of small intestine in weaning piglets. The results showed that the oligopeptides hydrolyzed from the residue of heparin extraction could promote amylase, lipase and trypsin activities in duodenum chime, increase villi height and reduce crypts depth of small intestine. This research provides a new thought of making use of porcine intestine.
