摘　　要：The present study investigated the effects of dietary supplementation of xylooligosaecharides （XOS） and probiotics （PR） on performance, milk compo- sition and diarrhea incidence of sows or their offspring. From day 90 of gestation until weaning, a total of 60 muhiparous sows were randomly assigned to three groups and given three different diets that included either the control diet （ sCON, n = 20 ）, the control diet containing 175 mg/kg XOS （ sXOS, n = 20 ） or 175 mg/kg XOS and 300 mg/kg probiotics （sXOS ＋ PR, n =20）. On day 21 of age, offspring were assigned within sow treatments to the piglet basal diet （pCON） or the piglet basal, diet supplemented with 175 mg/kg XOS （pXOS） for 28 d. Sow feed intake was recorded daily. Body weight and feed consumption of the pigs in each replicate were determined biweekly （on day 0, 14 and 28） to calculate the average daily gain （ADG） of body weight, average daily feed intake （ADFI） and the gain-to-feed ratio （ G： F）. The colostrum and milk samples were obtained on day 0 and 14 of lactation, respectively. Sow XOS or XOS ＋ PR dietary had no effect on the number of total piglets born and born alive and the piglet weight at birth. Milk composition in sow colostrum and milk were not affected by sow diet XOS or （ XOS ＋ PR） supplementation （ P 〉 0.05 ）. No maternal dietary effect was observed on the weaning weight and pre-weaning weight gains of piglets. However, there were interaction effects between sow and piglet dietary treatments on diarrhea rate and diarrhea index during day 35 -49 （P = 0.03 ） and day 21 -49 （P =0.02）. Although sow diet XOS and （XOS ＋ PR ） supplementation did not influence growth performance of weanling piglets, such as ADG and ADFI （ P 〉0.05 ）, piglets XOS supplementation significantly decreased ADFI during the whole experiment period and increased G： F during day 35 -49 and day 21 -49 （ P 〈0.05 ）. These results might suggest that combination of XOS and PR in sow diets haThe present study investigated the effects of dietary supplementation of xylooligosaecharides （XOS） and probiotics （PR） on performance, milk compo- sition and diarrhea incidence of sows or their offspring.
