Abstract

Abstract:

Uterine tissue nutrients are nutrients secreted by the uterus during animal reproduction， including amino acids， proteins， lipids， sugars， and other metabolites. Before implantation， the embryo relies on the tissue nutrients secreted by the uterus for nutrition. Their secretion is dynamically regulated by the estrous cycle， pregnancy status， uterine health， and maternal nutritional status. This article summarizes the changes in uterine fluid tissue nutrients under the estrous cycle， pregnancy status， nutritional levels， and endometritis. Through the study of these patterns， a more favorable uterine environment can be provided for the early development of embryos.

Key words: cow, tissue nutrients, estrous cycle, endometritis, nutritional factors
