Explanation:
The primary function of the reproductive system in farm animals is the reproduction and propagation of the species. The reproductive system in farm animals, including cows, sheep, pigs, and poultry, is responsible for the production of gametes (sperm and eggs) and facilitating the process of fertilization. It involves the functioning of reproductive organs, such as the ovaries, testes, uterus, and oviducts, as well as hormone regulation.
