is the cornerstone of both the dairy and beef industries. Efficient reproductive management directly dictates herd profitability, milk production volume, and genetic progress. 🔬 Core Biological Concepts
: The corpus luteum actively produces progesterone to maintain a potential pregnancy. Bovine Reproduction
: The CL regresses if no pregnancy is detected, and the body prepares for a new heat cycle. is the cornerstone of both the dairy and beef industries
: The cow is in heat and sexually receptive to the bull. milk production volume
: 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
: Ovulation occurs, and the corpus luteum (CL) begins to form.
