Answer :
Final answer:
Contemporary farms use artificial insemination to multiply male genetic contributions, increase fertility success rates, and reduce costs. It also enables the management of breeding cycles and improvement of herd genetics, providing a controlled process for breeding that enhances farm efficiency and safety. The correct answer is option 4.
Explanation:
Contemporary farms often choose to use artificial insemination (AI) due to a variety of reasons. One significant advantage is the ability to multiply male genetic contributions, making it possible for a single male to inseminate a larger number of females than would be feasible naturally. Furthermore, AI can enhance fertility success rates and reduce costs associated with natural breeding processes. AI also allows for the management and control of breeding cycles, facilitating breeding at the most opportune times. Improvements in the preservation and viability of sperm have addressed timing and logistical constraints, making it easier to inseminate females when they are most fertile.
