PRODUCTIVITY AND FATTY ACID COMPOSITION OF BROILER CHICKENS BLOOD SERUM WHEN FED BILE

Abstract

With the rapid development of intensive poultry farming, fats and oils are widely used as the most effective high-energy feed ingredients. Bile acids are powerful "digestive surfactants" that aid in the emulsification and absorption of lipids, including fat-soluble vitamins. Cattle bile was added to the diet of broiler chickens of the experimental groups, group I - 0.05%, group II - 1%. In the blood serum, a significant decrease in palmitic FA (C16:0) is observed in experimental groups I and II, so the difference with the control was 2.9% (p<0.05) and 4% (p<0.05). Biochemical analysis of blood serum showed that with the introduction of bile in experimental groups I and II, there was a significant increase in cholesterol concentration of 15.1% (p<0.05) and 11.6% (p<0.05) relative to the control. The level of cholesterol in the blood may increase due to the high need of the body for the synthesis of bile salts. Analysis of the serum FA composition showed a significant decrease in palmitic FA (C16:0) observed in experimental groups I and II, so the difference with the control was 2.9% (p<0.05) and 4% (p<0.05), respectively. By the end of the experiment, the maximum live weight indicators were recorded in group II (1% bile), the difference with the control was 4.5%, respectively. Thus, additionally administered bile acids may affect the ability to transport cholesterol from peripheral tissues to the liver, as well as improve broiler growth performance by increasing the solubility and absorption of dietary fat and fat-soluble nutrients.
