Animal Cycle of Life: Estrus and Anaestrus

Animals undergo various cycles throughout their lives, one of which is the estrus and anaestrus cycle. During the estrus phase, animals become highly receptive to mating, while in the anaestrus phase, they become unreceptive and unable to conceive. This cycle plays a crucial role in maintaining the health and well-being of animals, as it regulates their reproductive system and ensures that resources are allocated efficiently to support their offspring. Understanding this cycle can help us appreciate the natural world and appreciate the role of animals in our lives.
