Fast recovery of feed intake and milk production are very important in the management of lactating sows because they are directly related to sow and litter performance. It is also known that parity is one of factors affecting feed intake and milk yield during lactation. Therefore, the objective of this study was to evaluate effects of different parities on productive performance of lactating sows fed diets containing different levels of DDGS. A total of 245 sows were divided into 3 parity groups of 1 to 2, 3 to 5, and over 5 parities. Within each parity group, sows were allottedto 1 of 4 dietary treatments that were prepared by inclusion of 0, 10, 20, and 30% DDGS in lactation diets. Diets were fed to sows during lactation.Sows with parities 1-2 had lower (p ＜ 0.05) initial sow body weight, sow feed intake, sow weight change, and sow backfat change during lactation than sows with parities 3-5 as well as parities over 5. However, sows with parities over 5 had lower (p ＜ 0.05) litter size at weaning, litter birth weight, litter weaning weight, and piglet average daily gain and higher pre-weaning mortality than sows with parities 1-2 as well as parities 3-5. In conclusion, parity influences productive performance of lactating sows.
