Effect of various fats on digestibility of nutrients in diet of calves

Abstract

Abstract Article presents results of study on effect of various vegetable fats on digestibility of the main nutrients in young cattle. We obtained new data on effects of fats on absorption of amino acids, analyzed blood of experimental animals, depending on source of lipids. We found that use of native form of fat contributes to less intensive digestion of raw fat, in contrast to prepared. In this case, fatty acid composition plays significant role. Transformation of amino acids showed slight difference between the samples. As result of our research, thanks to unique surgical operation on transplantation of the pancreatic duct into isolated segment of intestine, new knowledge was obtained about exocrine function of pancreas, absorption of nutrients, and biochemical parameters of blood in cattle when exposed to fats in animals. Thus, obtained the data reflect body’s response to various types of fats, administered in doses that can be digested by body, without disrupting metabolism of other substances.
