Abstract

The main focus of the article is on recent research related to digestive efficiency and feed processing in cattle and forage preservation. One study developed a novel in vivo model using postruminal casein infusion and glucagon-like peptide 2 (GLP-2) administration to selectively increase pancreatic and small intestinal carbohydrase activities, enhancing starch digestion in cattle fed high-grain diets. Another study evaluated the effects of curing extent on the in vitro ruminal fermentation kinetics of red clover hay and silage, finding that ample curing improved fermentation parameters in hay but had no significant effect on silage across storage phases. These findings contribute to understanding physiological and processing factors that influence feed efficiency and nutrient utilization in ruminant production.
