Recombinant Bovine Growth Hormone (rBGH) is described as:

• A. A hormone used to promote meat marbling.
• B. A pesticide.
• C. A synthetic growth hormone increasing milk production.
• D. A feed additive to color milk.

Answer: (C)

Recombinant Bovine Growth Hormone is a synthetic growth hormone given to dairy cows to boost milk production. That means the purpose is to increase how much milk a cow can produce, not to affect meat quality or color the milk. It is not a pesticide, nor a feed additive used to color milk, and it doesn’t relate to marbling in beef. In the US, it was developed to raise milk yield, though regulatory and labeling practices vary by country due to consumer concerns about hormones and animal welfare.
