概括

补充液体乳清可以改善猪的生长和肠道健康. 它改善了肠道形态,增强了粘膜防御,并积极影响了瘦素信号,支持其在动物营养中的使用.

科学领域:

动物营养
胃肠病学
内分泌学

背景情况:

液体乳清是一种富含营养的乳制品副产品,可用于动物料.
关于LW对猪肠道形态和内分泌信号的影响的数据有限.

研究的目的:

研究液体乳清对成长中的猪肠道形态和内分泌信号的影响.
评估LW作为一种功能性食策略的潜力.

主要方法:

14只杂交的猪被分为对照组和LW补充组.
猪被养成颗粒的饮食,含有或不含有1.5升LW.
分析了肠道形态,杯状细胞数量和特定激素表达 (Cholecystokinin8,Galanin,leptin).

主要成果:

在猪中,LW补充剂显著增加了体重.
在LW养的猪中,肠道分析显示的高度,密室深度和肌肉外部厚度增加.
在LW群体中,杯状细胞的丰度和瘦素的表达显著更高,表明粘膜防御增强和内分泌信号发生改变.

结论:

液体乳清促进了猪的生长,肠道粘膜重塑和神经内分泌信号传递.
作为一种功能性饮食策略,LW是有前途的,但应考虑适应.

Histology of the Small Intestine

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
