| Abstract: | This experiment was conducted to evaluate the effects of dietary supplementation with different levels of cellulose and feeding environment on growth performance,nutrient apparent digestibility and small intestinal villus morphology of weaned piglets.A total of 1296 piglets weaned at 24 days with no significant difference in average body weight were randomly divided into 4 groups with 324 piglets per group and 6 replicates per group(54 piglets/replicate).Weaned piglets in groups T1 and T2 were fed 0%and 2%cellulose diet in good enclosures for the first 2 weeks after weaning,and piglets in groups T3 and T4 were fed 0%and 2%cellulose diet in poor enclosures for the first 2 weeks after weaning,respectively.Results:In terms of dietary cellulose level,body weight,average daily gain and feed efficiency of weaned piglets with good environmental conditions were significantly better than those with poor environmental conditions(P<0.05),but dietary cellulose level had no significant effect on growth performance of weaned piglets(P>0.05).Under the same feeding conditions,dietary supplemented with 2%cellulose significantly reduced the apparent digestibility of dry matter,crude protein and gross energy of weaned piglets(P<0.05).The dry matter apparent digestibility of weaned piglets with good environmental conditions was significantly higher than that of piglets with poor environmental conditions(P<0.05).Under the same dietary cellulose level,jejunum villus height and crypt depth of piglets in better feeding environment were significantly higher than those in poor feeding environment(P<0.05),while 2%cellulose supplementation significantly reduced jejunum crypt depth in the same feeding environment(P<0.05).There was a significant interaction between dietary cellulose level and feeding environment on the ratio of jejunum villi height to crypt depth(P<0.05).Conclusion:Feeding environment had a significant effect on the growth performance and morphology of jejunum villi of weaned piglets,and poor feeding environment reduced the growth performance.Dietary supplemented with 2%cellulose inhibits apparent digestibility of dry matter,crude protein and energy of weaned piglets. |
