Morphological differences according to uterine tissue remodeling during estrus between sika deer and water deer

Abstract

The reproductive physiology of deer and elk is characterized by 'silent ovulations' that occur for about 8 to 10 days when they exist in a herd during the breeding sea-son. This phenomenon differs from Artiodactyla animals, which tend to ovulate without showing clear signs of estrus, such as monovulatory species, and have a general reorganization of the uterus or corpus luteum (Asher et
