1, there is no feed, the entire lactation period depends on breast milk to maintain the energy needed for growth, resulting in hunger stress, easy to eat the piglets to eat foreign objects, is caused by the late Xujia pig diarrhea a reason. In addition, the gastrointestinal function of the piglet is not exercised, and the potential for future weaning stress is buried. At the same time, it is easy to delay the estrus of the sow after weaning.

2. Piglets do not drink water during breast-feeding, which causes thirst stress. It is easy for piglets to urinate and cause diarrhea.

3, weaning stress too much.

The improvement method is to drive the piglets that are to be weaned for 28 days from the original circle. Then all the weaned pigs are rushed to the two heads in the delivery room and fed to the nursery for a few days. Among the weaning stresses are: (1) The pig should not be driven away from the original circle, and the big pigs should be driven away. The pigs stay in the original circle for a week (but Xu Shu’s sow-free sow bar, big pigs cannot leave, comments Change several large columns and wean the pigs.) (2) Weaned piglets collectively are in a large column. It is a stress. If there is a nursery column, it is a small column, a nest, or a column. . (3) Weaned pigs only eat breastmilk during suckling and they directly transition to feed after weaning. They have a very large bowel strain on piglets and can cause long-term growth of pigs.

4. There is no feed transition between the stages of commercial pigs. (Another reason is that the house is too large, which results in a large difference in the body weight of the pigs in the column. It is impossible to accurately think about the feed patterns at each stage, and the breed is relatively extensive. It has been proposed that three buildings and four buildings be reconstructed, at the very least. One column and one barrel

5, conservation, too few fattening rooms, the first few days of weaning pigs transferred group, the nursery did not empty the bar, Xu Shu directly to the weaned pigs just arrived in the pigs in the nursery column (the pigs in the column about 30 pounds) The stress on weaned pigs is great.

The first three stresses improved after reaching the upper bed. Under such extensive farming conditions, there is no good material effect with good material.

Other problems found on this farm are:

1, there is no empty sow bar, so that sows can not leave the delivery room after weaning, weaning sows in the delivery room affect their normal estrus.

2. The sow trough design is irrational and the feed waste is serious. The sow trough in the field is flat and the troughs are as tall as the two side walls. The reasonable bottom of the trough should be "U" type, and the front and rear sides of the trough should be high and low.
