Abstract:
To evaluate the effects of supplemental probiotics and xylo-oligosaccharide on performance,digestive enzyme activities,blood index and intestinal microflora.Two hundred and forty crossbred early weaned PIC piglets with an average initial weight of (6.83 + 0.9) kg,weaned at (21 ± 2) d of age,were divided into four groups.Control Ⅰ (positive diet,with no probiotics and xylo-oligosaccharide but more fish meal,whey powder and little soybean meal),Control Ⅱ (negative diet,with no probiotics and xylo-oligosaccharide but less fish meal,whey powder and more soybean meal),Negative diet + 0.035 % probiotics,negative diet + 0.002% xylo-oligosaccharide.The results of theses studies suggested that whey powder and fish meal from 5.50% to 2.50%,soybean meal from 22.50% to 26.50% could result in decreasing of alimentary canal enzyme activity,blood sugar,total serum protein and the quantities of Bacillus in appendix(P<0.05),and raising of serum urea nitrogen,the quantities of Escherichia coli in appendix,diarrhea indexes and Feed/Gain(P<0.05).Addition of probiotics and xylo-oligosaccharide could significantly improve the activities of alimentary canal protein,lipase and amylase(P<0.05),decrease Feed/Gain and the levels of blood sugar and decrease the levels of serum urea nitrogen and improve protein equilibrium in blood and energy metabolism.The quantities of bacillus were improved,Escherichia coli were decreased in appendix(P<0.05).Diarrhea indexes were decreased(P<0.05).Whether adding probiotics and xylo-oligosaecharide or not could not affect ADG and ADFI (P>0.05).Addition of probiotics and xylo-oligosaccharide could improve digestive function,beneficial microbial population of post-alimentary canal,Feed/Gain and prevent the diarrhea of piglets.
