Effects of Feeding Conditions and Parity Body Weight on Sow Lactation

First, drinking water: sow milk contains about 82% water, and insufficient water supply will affect the sow's milk yield, often making the milk thicker and increasing its fat content. Second, feed: feeding more green and succulent feeds, such as pumpkin, carrot and Swiss chard, helps improve lactation capacity. In addition, the number of feedings and feed preparation also affect the sow's milk yield. Third, the sow's age and parity: under normal circumstances, the milk yield of the first parity is relatively low, then gradually rises, and gradually declines after the 4th to 5th parity. Fourth, individual size: generally, sows with a larger body weight produce more milk than those with a smaller body weight. This is because sows with a larger body weight lose more weight, which is needed for lactation.
