12 tips for feeding hyperprolific lactating sows

摘要

The beneficial effects of increased feed intake during lactation on sow reproductive performance are well known. Sows with minimal body fat and protein loss during lactation take less time to return to estrus after weaning. In addition, subsequent litter size tends to be larger, depending on sow condition. For example, for each 10 percent of body fat sows lose during lactation, subsequent litter size isreduced by one piglet. Likewise, each kilogram of body weight sows lose during the previous lactation results in one extra day until conception. The effects of increased feed intake during lactation on litter growth are less well documented (numerically).
