Why should we abandon the positioning column and use the large column to feed sows?

In the sow automatic feeding management system, sows are raised in large pens instead of traditional positioning pens. This is mainly because sows do not get exercise under the condition of positioning pen feeding, which increases the risk of disease; the stress on sows during production is large, which easily leads to embryo death in early pregnancy; the individual feeding amount is not easy to control, resulting in uneven fat and thin among sows in the group, and the consistency of the group is poor; the animal welfare requirements are not met. In the European Union from January 1, 2006 formally entered into force in the new food hygiene law, strengthened the provisions of animal welfare. These are all places worthy of our pig producers 'attention. -------------------------------------- Now the conditions are not up to ~~-------------------------------------- But "individual feeding is not easy to control" This is also a disadvantage of the positioning column, some far-fetched!-------------------------------------- From the perspective of investment and income, advanced ones are all good, but ordinary people can't afford to invest. -------------------------------------- I'm working on the locator bar and the birthing bed.
