Application Rsearch Of Diffierent Protein Raw Material Combinations In Sucking Pig's Artificial Micro-Diets

This paper investigates the effection of diffierent Protein Combination in Performance,Antioxidant,Digestive enzyme activity,gastrointestinal bacterial flora (GIBF) and Gastrointestinal development of suckling pig.12 (landres×large) pregnant sows whose expected date of confinement(EDC) were in two days were choosed based on the variety,birth order,day old,weight to be used.Gain the weight when the littles were borned,then divide them to 3 groups,four repeats per group according to the weight. Three protein combinations were feed to approach the influence on suckling pig (spray-dried blood plasma albumen powder and dried porcine solubles were experimental groupⅠ,whole-milk powder and hamlet protein were experimental groupⅡ,dried whey and hamlet protein were experimental groupⅢ),The results showed that:(1) The diarrhea rate of Experimental groupⅡwas lower than that of Experimental groupⅢ(p<0.05); (2) The digestibility of crude protein of Experimental groupⅢwas lower than that of Experimental groupⅠand Experimental groupⅡ(p<0.05); (3)Experimental groupⅢand Experimental groupⅡhad a significant effect at the P<0.05 level on the absolute weigh of liver; (4) Spray-dried blood plasma albumen powder and dried porcine solubles had a significant effect on the trypsin activity, Experimental groupⅢand Experimental groupⅠat the P<0.05 level; (5) Villus length of duodenal mucosa of experimental groupⅠwas the shortest of the three groups at the P<0.01 level; Dried whey and hamlet protein had a significant effect at the P<0.05 level with Experimental groupⅠon crypt depth,and lower than the other groups; (6) Villus length of mucous membrane in anterior segment of jejunum in Experimental groupⅠwas very significant longer than Experimental groupⅡ(P<0.01), Experimental groupⅢand Experimental groupⅠwas longer than Experimental groupⅡat the P<0.05 level; spray-dried blood plasma albumen powder and dried porcine solubles had a very significant on the villus width,and was lower than Experimental groupⅢ(at the P<0.01 level) and Experimental groupⅡ(at the P<0.05 level); (7) Experimental groupⅠwas significant higher than on glutathione peroxidase at the P<0.05 level; (8) Experimental groupⅡhad the most Bacillus acidi lactici in midpiece of jejunum, Experimental groupⅡand Experimental groupⅢat the P<0.05 level.
