Pregnant sow house is a good positioning bar or a good circle?
Pregnancy sow is a special stage, the most special place is almost full to limit the feeding; if not limited, will lead to sow fat, waste of feed, but also the emergence of fetal, fetal uneven, less postpartum milk, Dystocia and other issues, so restrictions on feeding is the sow breeding must be strictly controlled technical means. But the restrictions can not be too much, if too thin, sows due to malnutrition caused by birth heavy, weak vitality, postpartum milk shortage and weaning after the issue of non-estrus and other issues. Before the pig, mostly a sow a circle, the above problems do not exist; but now pig, the scale is growing, coupled with the lack of land resources, a pig is difficult to do a circle; in order to save the ground , Many pig farms will be a long sow into a circle, relatively speaking, each land occupied by the reduction of pigs; but the big circle feeding, but also the uneven feeding, sow fat and too thin, and Is not conducive to the production performance of the play; and in the early pregnancy, between the sows because of fighting and collision, conception rate greatly reduced. In response to this situation, people invented the positioning bar breeding, to prevent the fight, but also according to the requirements of control of feed; but the positioning column and the emergence of the phenomenon of lack of exercise, dystocia increased, increased foot and foot disease, sow shorter life The That in the end is the use of positioning bar, or the use of large circles? I think the best way is both large circles, but also positioning the column; in the need for strict restrictions before and after a month, the use of positioning bar breeding, both sows quietly miscarriage, but also strictly limit the feed; In the middle of a period of time, the use of large circle feeding, because the middle of pregnancy, sows strong ability to resist stress, a slight increase in the amount of activity, will not cause sow abortion, but also increase sow activities. Of course, there are many ways to solve the various problems of pregnant sows; but if the planning of the pig farm have been thoughtful, you can avoid unnecessary trouble later.
