Factors affecting lactation in sows-- feeding conditions, parity weight

First, drinking water: the water content in sow milk is about 82%. Insufficient water supply will affect the milk production of pigs, often thickening the milk and increasing the fat content. The second is feed: feed more green juicy drinks, such as pumpkins, carrots, cowhide vegetables, etc., help to improve lactation. In addition, the feeding times and feed preparation also had an effect on the milk yield of sows. The third is the age and parity of sows: in general, the milk yield of the first fetus is lower, then increases gradually, and decreases gradually after 4 to 5 births. Fourth, individual size: generally heavy sows produce more milk than low-weight sows. Because heavy sows lose more weight, this is needed for lactation.
