Histological features of broilers’ liver of Arbor Ikrez cross at different stages of post-embryonic ontogenesis

The aim of the research was to study age-related dynamics of histological characteristics of the liver of broiler chickens cross of Arbor Ikrez. As the material of the research the liver of the birds 1-, 7-, 14-, 21-, 28-, 35-and 42-day age served. The pieces of the organ were fixed in 10 % solution of formalin. Histological preparations were made by standard methods and painted with hematoxylin and eosin, and also Schiff-iodine acid with the methylene blue. Broiler chicken’s liver consists of stroma and parenchyma. The largest changes in the structure of the liver occur from the first till the twenty-first day of postembryonic ontogenesis. In one day-aged chickens frame drawing of the liver is not expressed, hepatocytes are located chaotically; the cytoplasm is foamy, containing fatty drops. On micropreparations of liver zones of formation of hepatic lobes in which blood vessels and bile ducts are not visible are looked through, hepatocytes densely adjoin to each other and twisted like a whirlwind...
