What does it mean to raise pigs in multi-point (one-point, two-point) breeding?

What does it mean to raise pigs in multi-point mode (one-point mode, two-point mode)? -------------------------------------- Now there are generally two kinds, the United States is mostly two-point type, and sows and piglets are raised together, piglets and fattening pigs are raised together, and the other is one-point type, and all pigs are raised in one place. Divided feeding is an effective measure to control disease. Now there are mainly two points, three points and four points. Through practice, it is shown that the effect of 3 and 4 points is almost the same. I recommend 3:00. In fact, 3-point feeding, if China's large-scale pig farms do this, then it would require 3.6 million square kilometers. If there are conditions, it is recommended to use 2 points to achieve good results, that is, breeding pigs and fattening are separated. The big three points are two pig farms 1000 meters away, and the small three points are about 50 meters away. -------------------------------------- Well said, thank you!-------------------------------------- The sofa and bench are both good. I learned-------------------------------------- - --------------------------- Chinese-style three-point: production distinction breeding pigs, nursery pigs, pigs three. Foreign countries are divided into three small fields separated by a certain distance. Prevention of vertical transmission of disease (different ages).
