How much water does a lactating sow typically drink each day?

A lactating sow typically drinks around 5 gallons of water each day. This high water intake is essential for maintaining milk production and overall health during lactation. The energy and nutrients required to produce milk demand an increased water supply, as milk is largely composed of water. Additionally, adequate hydration supports the sow's metabolic processes and helps to prevent conditions such as dehydration and decreased feed intake, which can negatively impact her health and the growth of her piglets.

While the other options present lower water intake figures, they do not meet the physiological needs of a lactating sow. It's important for producers to monitor water availability and quality, especially during lactation when the sow's demands are significantly heightened.
