Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.
