[Growth hormone (BST) in animal production]

Area of Science:

• Animal Science
• Endocrinology
• Biotechnology

Context:

• Bovine somatotropin (BST) is a growth hormone primarily studied in cattle.
• Its application extends to enhancing milk and meat production across species.
• Concerns exist regarding its impact on animal reproduction and food safety.

Purpose:

• To evaluate the efficacy of BST hormone in livestock production.
• To analyze the species-specific effects of BST, particularly in non-bovine species.
• To investigate the hormonal mechanisms and potential reproductive interactions of BST.

Summary:

• BST hormone significantly boosts milk production in cows.
• Its effects on meat production in cattle, swine, and poultry were analyzed.
• Mechanisms like lactogenesis and impacts on nitrogen levels, ribosomal RNA (rRNA), and proteoglycans were examined.

Impact:

• Provides insights into BST's role in animal agriculture and food production.
• Addresses potential biological effects and necessary precautions for consumers.
• Highlights the importance of species-specific considerations for hormone application.
