Effects of feeding high concentrate diets to lactating dairy goat on VFA transportation and cholesterol metabolism
Introduction In ruminants, rumen is the major organ for diet fermentation and nutrients supply due to the huge amount of microbial ecosystem.Ruminal volatile fatty acids (VFAs) can be efficiently absorbed by the rumen epithelium via diffusion or a protein-mediated pathway(Aschenbach et al., 2011).Some studiesshowed that both VFAs and pH can affect the mRNA expression of VFAs transporters(Yan et al.,2014).Feeding a high-concentrate (HC) dietincreased the total volatile fatty acid (VFA) concentrations in rumen fluid and then caused a significant decrease in ruminal pH, and simultaneously the ruminal lipopolysaccharide (LPS) concentrations were significantly increased (Tao et al., 2014a;Tao et al.,2014b).Increasing absorption and metabolism of VFAs in rumen epithelial cells has been proposed as a potential mechanism for decreasing the risk of ruminal acidosis.
