早期断奶仔猪肠黏膜的营养调控

肠黏膜的发育与成熟状况是制约幼畜快速生长的关键因素。早期断奶仔猪肠黏膜免疫力较低,容易遭受饲粮抗原的刺激而引起肠黏膜过敏性损伤,诱发仔猪断奶后腹泻。通过肠黏膜营养调控技术,补充肠黏膜能量营养, 促进肠黏膜的发育与成熟,修补断奶引起的肠黏膜损伤,可以从根本上减轻仔猪断奶后腹泻的发生。本文对早期断奶引起的肠黏膜形态变化以及有利于修复受损伤肠黏膜的营养物和调控因子进行了综述。

Nutritional regulation of the intestinal mucosa in early weaned piglets

The growth and mature conditions of the intestinal mucosa are crucial to the growth of young livestock.The immune function of the early-weaned piglet is distempered, it is easy to be damaged and result in diarrhea.Some nutrients and nutrient regulatory factors can supply energy and promote the growth and maturity of the intestinal mucosa,and repair the damaged mucosa and relieve diarrhea of the weaned piglet.The change of small intestine morphology of the weaned piglet,and some nutrients and nutrient regulatory factors which are good to the intestinal mucosa damage were summarized.
