Abstract

Lipid metabolism is one of the most fundamental elements in adaptation, including stress implementation mechanism in poultry. The study was aimed at assessing the individual indicators characterizing the level of lipid metabolism in chickens with different resistance to stress. Stress reaction was simulated under conditions of industrial environment. Lipid profiles were studied in the blood plasma taken from the parent flock of Hubbard F15 cross meat-type chickens at the age of 41 weeks. The chickens were subjected to the stress by subcutaneous administration of turpentine according to the method developed by A.V. Miftakhutdinov (2012). Blood samples were taken 60-90 minutes after administration. Adaptive responses of the chickens to the stimulus were characterized by a specific lipid metabolism expressed in a higher increase of triglycerides in blood plasma (on average by 2.3 times in the groups), the amount of lipoproteins of low and very low density (on average by 3 times in the groups) and total cholesterol (on average by 2.3 times in the groups). In comparison with stress-resistant chickens, stress-sensitive chickens showed more evident increase in the concentration of triglycerides (by 1.9 times) and cholesterol (by 64%) in 60-90 minutes after the administration of turpentine. It was due to the prevalence of cholesterol in very low density lipoproteins and reduction of cholesterol in low and high density lipoproteins. The confirmation of diagnostic value of the assessment of resistance to stress and its correlation with lipid metabolism are economic and biological qualities of chickens. Reproductive qualities have a high correlation coefficient (r > 0.75) with the level of stress sensitivity of chickens.
