The principle of grouping commercial pigs

First, pigs with similar sources, body weight, physical condition, temperament and feeding should be raised in a herd. The difference in weight within the same group of pigs should not be too large, no more than 3 to 5 kilograms for piglets and no more than 5 to 10 kilograms for shelf pigs. After grouping, it is necessary to maintain relative stability and generally do not change at will. The second suitable density. Generally, each continuous milking piglet occupies an area of 0.7 square meters, and each fattening pig occupies 1.2 square meters. Each group should be 10 to 15 heads. The feeding density can be appropriately increased in winter and decreased in summer.
