The morphometry of hepatocytes aт different stages of the development of chicken-broilers of arbor ikrez cross

The aim of the research was to study the age dynamics of morphometric indicators of hepatocytes of broiler chickens of Arbor Ikrez cross at different stages of their development. The object of the study was the liver of the poultry of seven age groups from 1 day to 42 days of age. Histological liver preparations were made according to conventional methods, stained with hematoxylin and eosin. The morphometry of hepatocytes was performed using "Cito 2.0" program. In broiler chickens, the hepatocytes were polygonal in shape; the nuclei were brightly colored basophilically with oval or rounded shape. On the periphery of hepatic lobule, portal triads were visible, including interlobular vein, artery, and bile duct. At the age of 1 day of broiler chickens, the area of hepatocytes was 23.66±1.06 mm2, the core area was 7.81±0.32 mm2, and the cytoplasm area was 15.80±0.81 mm2. Based on the conducted research, it was found out that the growth and cytodiferentiation of hepatocytes in broiler chickens of Arbor Aikrez cross during growing period from one day to 42 days of age had a number of regularities...
