Select boars are chosen from sows that are in the top what percent of a herd according to the sow productivity index?

• A. 10%
• B. 25%
• C. 50%
• D. 75%

Answer: (B)

The correct answer is that select boars are chosen from sows that are in the top 25% of a herd based on the sow productivity index. This decision is pivotal because the sow productivity index is a comprehensive measure used to evaluate the reproductive performance of sows, including factors such as litter size, weaning weight, and overall prolificacy. Selecting boars from the top 25% ensures that the genetic traits contributing to higher productivity and efficiency are propagated within the herd. By focusing on the top quarter of the herd, producers can enhance their breeding programs by incorporating desirable traits that lead to improved outcomes, such as better growth rates, increased litter sizes, and overall herd sustainability. This selective breeding strategy aligns with the goals of producing more productive and efficient livestock, ultimately benefiting the economic viability of the operation. The other percentages would not provide the same level of selectivity necessary for improving herd performance effectively.
