| The study was designed to determine the effects of dietary supplementation of CALSPORIN®(probiotic)on sow,litter performance and microflora changes in the feces of sows. Fifty-two cross-bred sows were divided into 2 groups that were fed either a corn-soybean meal based diet or the basal diet supplemented with 0.1% CALSPORIN® from d 80 of gestation until farrowing.After farrowing the concentration of CALSPORIN® was reduced to 0.01% in lactation diets.The sows were on the same dietary treatment 6 in lactation as in gestation.The sows were restricted fed(1%BW+500gms)and ad lib fed during lactation of a corn-soybean meal based diet. The results indicated that CALSPORIN® had no effect(P>0.05)on sow body weight changes and back fat thickness during gestation,litter size,average feed intake, and body weight changes during lactation. The total number of pigs born and weaned was not influenced by dietary treatment.The average daily gain(ADG)of piglets from sows fed CALSPORIN® diet during gestation and lactation was 214.0g,which was significantly greater(P<0.05)than 200.4g of the piglets from sows fed control diet. The number of Clostridium perfringens in the feces of CALSPORIN® fed sows was less(P<0.05)than in the feces of the control fed sows(6.13log vs 7.13log,CFU/g feces). The number of Bifidobacterium in the feces of CALSPORIN® fed sows was higher(P<0.05)than that of control the group fed sows(8.56log vs 7.27log,CFU/g feces). The number of total anaerobic bacteria in the feces of piglets from the sows fed CALSPORIN® diet was less(P<0.058)than in the feces of piglets from the sows fed control diet(9.54log vs 10.22log,CFU/g feces). In summary,CALSPORIN® could improve body weight gain of the suckling plglets and increase the number of Bifidobacterium in sows during gestation and lactation. |
