Abstract

In modern broiler poultry farming, technological stress of poultry is an important factor in reducing productivity. Developing new methods for decreasing the effects of stress on the broilers is one of the important goal. In an experiment on broiler chickens, the stress-protective effect of hydroxyzine, ascorbic acid and their complex on clinical indicators and productive qualities was studied. It was found that the use of hydroxyzine and its complex with vitamin C increases the average daily weight gain by 20%. With an increase in stocking density by 1.5 times, the level of erythrocytes decreases in all groups, but the use of hydroxyzine prevents the development of erythropenia. An increase in stocking density changes the leukocyte formula of the blood, increasing the proportion of lymphocytes by 18%. The use of anxiolytics does not affect the ratio of lymphocytes and heterophils. A conclusion is made about the positive effect of hydroxyzine on metabolic processes in chickens grown under conditions of technological stress.
