This study aimed to evaluate the effects of distillers dried grains with solubles (DDGS) during gestation on sow productivity, litter performance and milk composition. Thirty-six second-and third-parity (2.27 parity) sows (Yorkshire) were bred with semen from a pool of Landrace boars. The sows were randomly allotted to 1 of 3 groups and fed diets containing 0 (control), 12.5 or 25% DDGS during gestation. The sows were divided into 12 blocks of three animals. Piglets were cross-fostered, within dietary treatment groups 48 h after birth to standardise litter size to a range of 9 to13 piglets. The 25% DDGS supplementation resulted in a greater (P=0.03) average daily feed intake (ADFI) during lactation compared with control sows. The weaning-to-oestrus interval was shorter in sows receiving 25% DDGS diets compared to the control (P=0.01). The number of piglets born was similar among treatments. The addition of 12.5 and 25% DDGS to the gestation diet increased the average daily gain (ADG) of the piglets during lactation (P=0.04). The results demonstrated that feeding 25% DDGS does not have negative effects on sow or litter performance and increases the sow ADFI and the piglet ADG during lactation.
