To manage and improve herds, producers rely on several heavily researched breeding methods: Bovine Reproduction - Taylor & Francis
: 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
