In general, everything is reserved for the use of sows, has been weaned began to enter the breeding stage of the sow, we call the prepared sow, nurturing a good sow is one of the important conditions of high yield and reproduction, of course, Has been in the growing season, but its growth and fattening pig is different, in general, fattening pigs grow to 90 kilograms to 120 kilograms can slaughter, but the reserve sow, grow to a hundred kilograms or so to start configuration Just entering the breeding of breeding began.
After the weaning piglets are prepared to prepare the piglets of the prepared sows, it is necessary to start feeding the prepared sow material in order to effectively make the prepared sows develop well, and some sows produce less piglets, Also relatively high, this reason is not necessarily in pregnancy or feed and problems, there may be long-term feed nutritional deficiencies.
If the prepared sow in pregnancy with a bad nutrition, it will lead to piglets can not be healthy development, so in the diet to the back sow, eat according to different stages to different nutrition with, to avoid sow growth too fat, Leading to no development is not angry.
When the back sows in 50 kg or less, you can and fattening pigs with the same feed, 50 kg or more than fattening pig feed less, so you reduce the growth rate until To be fed about half a month before the start of feeding, in order to increase the amount of ovulation.
Compared with the fattening pig, calcium and phosphorus in the feed are relatively high, so that the accumulation of minerals in the bone to maximize, which can extend the sow breeding time.
The sow and the finishing pig diet is not the same as the increase in vitamins and trace elements, so that sows can be anorexia, in order to meet the nutritional requirements of the sow, you can increase the feeding of green fodder.
