Morphological changes of reproductive organs during egg formation of autochthonous Oravka hens

Abstract

Licensed under a Creative Commons Attribution 4.0 International License In this study we investigated the changes of reproductive organs and duration of egg formation in autochthonous Oravka hens. The changes of ovary and oviduct in defferent time were investigated on 66 hens at the top of the laying. Reproductive organs have to change their weight and morphological structure depending on the dynamics of egg formation. From ovulation to laying the ovary weight increased from 47.
