What are the factors affecting sow lactation

1. Drinking water: insufficient water supply will affect the lactation of pigs, which often thickens the milk and increases the fat content.

two。 Feed: feed more green succulent drinks, such as pumpkin, carrots, cowhide vegetables, etc., which is helpful to improve the lactation ability of sows.

3. The age and parity of sows: in general, the lactation of the first parturient is lower, then increases gradually, and decreases gradually after 4-5 parturition.

4. Body size: generally large sows produce more milk than low-weight sows. Because heavy sows lose more weight, this is needed for lactation.

5. Delivery season: spring and autumn, more milk production; cold winter, less milk production.

6. Sow estrus: sows are in estrus during lactation, which often affects the quality and quantity of lactation. At the same time, it is easy to cause white dysentery in piglets. Sows with high lactation will inhibit oestrus.

7. Disease: if the lactation sow is sick, such as cold, mastitis, pneumonia and other diseases, the milk yield can be reduced.
