【 摘 要 】

The article is devoted to the study of cytometric parameters of the epithelial layer of the mucous membrane of the oviduct of hens before the start of egg-laying, namely from 30 to 120 days of age. As a result of the analysis of the obtained cytometric indicators, it was found that the thickness of the epithelial layer of the cranial part of the oviduct progressively increases from 30 to 90 days of age. A similar trend is observed in the caudal part of the oviduct a month later, that is, from 60 days of age. Cranial epithelial cells had the largest nuclei at the age of 90 days, and caudal – at the age of 120 days. The sizes of epithelial cells in the cranial region varied from the minimum values at the age of 30 days to the maximum values at the age of 60 days. The minimum area of epithelial cells is noted in the caudal region, as well as in the cranial, at the age of 30 days. However, the maximum area of epithelial cells in the caudal region does not coincide with the cranial region, since the largest epithelial cells in the caudal region are observed at 120 days of age. The minimal ratio of nuclei to the cytoplasm in the cranial part of the oviduct was observed at 60 days of age, and in the caudal – at 90 days of age. The highest nuclear cytoplasmic ratio in the cranial part was recorded at 30 days of age, and in the caudal part – at 30 and 120 days of age.
