Reproductive Hormones
The cattle estrus cycle is a cycle of endocrine events associated with morphological changes in the cow’s reproductive tract accompanied with certain behavioral traits.
Cows receive estrus in a carefully regulated cycle, which gives repeated opportunities to the animals to become pregnant. It is regulated by the hypothalamic-pituitary-gonadal (ovary) axis producing hormones that dictate reproductive events in cattle.
