What is a notable characteristic of lactating sows concerning their feeding behavior?

Lactating sows exhibit a notable increase in their nutritional needs compared to their needs during gestation. This is primarily due to the energy and nutrients required for milk production to support the growth and development of their piglets. As a result, lactating sows typically require more feed to ensure they have adequate energy, protein, vitamins, and minerals.

During the lactation period, it's crucial for these animals to maintain their body condition and health while also providing the necessary nutrition to their young. Consequently, feeding strategies often focus on meeting these heightened requirements to prevent issues such as decreased milk production or health complications in both the sow and her piglets.

Other answers do not reflect the typical behavior of lactating sows. While some may experience fluctuations in feed intake due to various factors, the defining characteristic remains the increased feed requirement.
