R.Yu. Khokhlov, S.I. Kuznetsov

The authors estimated the length, the mass, the diameter of excretory region, and also the thickness of epithelial layer, the height and the width of the folds in mucous tunic, the structure of the wall of oviduct excretory region in hens of the Lowman Brown breed at the age of 150-140 days. It was shown that the morphological differentiation of oviduct excretory region in hens occurs at the age of 150-360 days.

Key words: oviduct, morphology, histology, hen, reproductive system.
