: 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. Bovine Reproduction
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 : Cattle are polyestrous, meaning they cycle continuously
: The CL regresses if no pregnancy is detected, and the body prepares for a new heat cycle. : Cattle are polyestrous
: The cow is in heat and sexually receptive to the bull.
: 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:
