2. Basic sows: One is to feed fully with compound feed, resulting in excess nutrients, sows are obese; second is excessive feeding, resulting in inadequate nutrition, sows are thin. 3. Poor sanitation of the pig house: Sows are susceptible to skin diseases, etc. Due to the systemic sewage, it is easy to pass the milk to the body surface to pass the pathogens to the piglets; the pathogens can also be passed to the boar through mating. 4. Sows out of time: some older, significantly reduced calving; some long-term estrus, multiple mating infertility: some genital tract inflammation, long-term infertility, etc. continue to raise, not timely eliminated. I have discovered that some sow sows do not produce a single child in a year or so and are still keeping them. As a production machine, the sow cannot produce normally, which will inevitably result in a decrease in overall production performance and production efficiency. 5. Sow population structure is irrational: the normal sow structure should be the first child and the proportion of multiple births is less, the proportion of the second to seventh child is relatively large, generally up to 70%. Can have better reproductive indicators. In addition, the number of sows should be proportional to the boar, usually 25:1; it will not result in excessive use of boars too low, affecting reproductive effects.

Errors that cannot be made during sow feeding
1. Reserve gilts: First, treat them as fattening pigs, allowing them to eat freely, causing sows to grow too large and affecting reproductive skills. Instead, they should treat them as basic sows and feed them on the worst feed. Cause sow thin, poor growth and development.
