What are the factors affecting sow lactation?
1. Drinking water: An insufficient water supply will affect the sow's milk yield, often making the milk thicker and increasing its fat content.
2. Feed: Feeding more green, succulent feed, such as pumpkin, carrots, and Swiss chard, helps improve the sow's lactation capacity.
3. Sow age and parity: Under normal circumstances, milk yield is lower in the first litter, then gradually rises, and gradually declines after the 4th to 5th litter.
4. Individual size: Generally, heavier sows produce more milk than lighter sows. This is because heavier sows lose more weight, which is needed for lactation.
5. Farrowing season: In spring and autumn, milk yield is higher; in severe winter cold, milk yield is lower.
6. Sow estrus: If a sow comes into estrus during lactation, it often affects the quality and quantity of milk, and at the same time easily causes white scour in piglets. In sows with higher milk yield, lactation will inhibit estrus.
7. Disease: If a sow becomes ill during lactation, such as with a cold, mastitis, pneumonia, and other diseases, milk yield can decline.
