What is the national average weaning age for commercial swine producers in 2012?

• A. 19.5 days
• B. 21.5 days
• C. 23.5 days
• D. 25.5 days

Answer: (B)

The national average weaning age for commercial swine producers in 2012 was 21.5 days. This age represents a standard practice in swine production at that time, balancing the needs for piglet growth and the efficiency of sow management. Weaning age is critical because it directly affects piglet health, growth rates, and the overall productivity of the herd. Weaning earlier than this average may lead to underdeveloped piglets, which can face health challenges and lower survival rates. Conversely, weaning later could increase the risk of sow health issues and reproductive inefficiency, as the sow may need additional time to recover before her next breeding cycle. Thus, the figure of 21.5 days is significant, as it reflects a point where producers found an optimal balance for the health and productivity of both the piglets and the sows. This average likely reflects various influences, including advancements in nutrition, management practices, and veterinary care available to swine producers at that time.
