Abstract. The results of histological examination of the internal organs of broiler chickens cross "Cobb-500" 5-day-old, subject to the receipt of their body gamma-HCH at 0.1 and 0.3 mg / kg of feed. It was found that the intake of broiler chickens pesticide leads to changes in histological structure of the internal organs of poultry.

         The liver samples revealed hepatocytes able granular dystrophy (cytoplasm and nuclei are stained badly affected hepatocytes are arranged in groups of 5-10 cells, interlobular connective tissue richly infiltrated with lymphoid cells rounded, almost all of which occupies the core area). Noted granular dystrophy of cardiomyocytes (their cytoplasm and nuclei are stained badly, and razvoloknenie glybchasty disintegration of muscle fibers, connective tissue infiltrated by lymphocytes rounded, almost all of which occupies the core area). In the kidney marked granular dystrophy renal tubular epithelial (tubules affected have a small gap or he is absent, epithelial tubules increased in size, the cytoplasm of epithelial tubules uniform, dull gray in the affected section of the tubules are arranged in groups of 10-20, renal interstitial infiltrated lymphocytes round, most of the area that occupies the kernel).

Keywords: broilers, pesticides, gamma-HCH, histological changes
