The anatomy and the digestive and absorptive function of the small intestine of lactating ruminants, particularly the dairy cow, are described. Methods for quantifying digestion within the small intestine and th
So except for foregut fermenting folivores the small intestine's surface is about proportional to metabolic demands. The different coefficient in foregut fermenters (including ruminants) remains to be explained. The degree of enlargement of the intestinal surface by Kerk-ring folds, villi and ...

Findings to date seem to suggest that these two physiological attributes for effective bacterial protein utilization are present in the small intestine; however, these attributes have a much lower capacity/impact in the colon. The gastrointestinal microbiome is likely a protein source of medium to ...
in this group is masked by a rapid change in digestion regimes, the intensity of nonspecific or specialized coprophagy, and the development of the fiber separation mechanism in the large intestine, which leads to high variability of results. The influence of body size is realized when larger ...
Differential T-Cell signaling in the two most distal regions of the small intestine (ileum and jejunum) was also noted, as well as differential expression of transporters that likely play a key role in nutrient uptake. Background Lactation is a time of a four- to five-fold increased energy ...
dilated intestine was found. Careful palpation of the intestine usually revealed the obstruction at the distal aspect of the dilated bowel. In all cases, the ileocaecal region was examined to complete the examination of the small intestines. The caecum, ileum and ascending colon were inspected, ...
aStarch hydrolysis in the small intestine of ruminants is achieved by the action of a-amylase assisted by surface oligosaccharidases, as in other species (Gray, 1992; Harmon, 1993). Since on average 5±20% of starch consumed by cattle is digested post-ruminally (Huntington, 1997), 淀粉加...
Yucca plant extract can promote the proliferation of beneficial bacteria, improve the intestinal environment, and facilitate the growth and development of intestinal villi; it can reduce the production of ammonia, stabilize the pH in the intestine, and promote protein dig...
