Nursing pigs and fattening pigs of different ages cannot be mixed

Some pig farms are building pig fatten crate or breeding sow herds when there is too much difference in the ratio between batches, or the calculation is not accurate, and the planning is improper. As a result, the pig fatten crate is not enough to be reserved, and short-term or long-term conservation of pigs occurs. The phenomenon of co-breeding with fattening pigs. On the one hand, for pig farms that are not free-feeding, nursery pigs need to be fed multiple times a day, while finishing pigs can be fed twice a day. Feeding nursery pigs will inevitably cause disturbance to the rest of the finishing pigs. It affects the rest and growth of fattening pigs; on the other hand, fattening pigs are older and get more pathogens from outside contact than nursery pigs. Pathogens in the excrement can infect nursery pigs, causing unnecessary potential risks.
