: The corpus luteum actively produces progesterone to maintain a potential pregnancy.

: The CL regresses if no pregnancy is detected, and the body prepares for a new heat cycle. Bovine Reproduction

: Cattle are polyestrous, meaning they cycle continuously throughout the year if not pregnant. The average cycle lasts 21 days and is divided into four distinct phases: : The corpus luteum actively produces progesterone to

: Gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, progesterone, and prostaglandin ( PGF2αcap P cap G cap F sub 2 alpha end-sub ) orchestrate the entire reproductive process. 🚜 Breeding & Management Methods

: A cow's pregnancy typically lasts about 283 days (roughly 9 months), fluctuating slightly depending on the specific breed and the sex of the calf.
