| 1 | Effects of creep feeding and supplemental glutamine or glutamine plus glutamate (Aminogut) on pre- and post-weaning growth performance and intestinal health of piglets显示文摘Background: Creep feeding is used to stimulate piglet post-weaning feed consumption.L-Glutamine(GLN) is an important source of fuel for intestinal epithelial cells.The objective of this study was to determine the impact of creep feeding and adding GLN or AminoGut(AG;containing glutamine + glutamate) to pre-and post-weaning diets on pig performance and intestinal health.Litters(N = 120) were allotted to four treatments during 14–21 d of lactation: 1) No creep feed(NC,n = 45);2) creep fed control diet(CFCD,n = 45);3) creep fed 1% GLN(CFGLN,n = 15);4) creep fed.88% AG(CFAG,n = 15).After weaning,the NC and CFCD groups were sub-divided into three groups(n = 15 each),receiving either a control nursery diet(NC-CD,CFCD-CD) or a diet supplemented with either GLN(NC-GLN,CFCD-GLN) or with AG(NC-AG,CFCD-AG).Litters that were creep fed with diets containing GLN or AG also were supplemented with those amino acids in the nursery diets(CFGLN-GLN,CFAG-AG).Glutamine was added at 1% in all three post-weaning diet phases and AG was added at.88% in phase 1 and 2 and at.66% in phase 3.Results: Feed conversion(feed/gain) showed means among treatment means close to significance(P = 0.056) and Tukey's test for pairwise mean comparisons showed that Pigs in the CFGLN-GLN group had the best feed conversion(feed/gain) in the first three-week period post-weaning,exceeding(P = 0.044) controls(CFCD-CD) by 34%.The NC-AG group had(P = 0.02) the greatest feed intake in the last three week of the study,exceeding controls(CFCD-CD) by 12%.CFGLN-GLN,CFCD-GLN and sow reared(SR) pigs had the greatest(P = 0.049) villi height exceeding the CFCD-AG group by 18%,20% and 19% respectively.The CFAG-AG group had the deepest(P = 0.001) crypts among all treatments.CFGLN-GLN,CFCD-GLN and SR groups had the greatest(P = 0.001) number of cells proliferating(PCNA) exceeding those in the NC-CD group by 43%,54% and 63% respectively.Sow reared pigs showed the greatest(P = 0.001) intestinal absorption capacity for xylose and mannitol.Conclusion: Supplementation of creep feed and nursery diets with GLN and/or AminoGut in the first three week improved feed conversion possibly due to improved intestinal health. | Rafael A Cabrera James L Usry Consuelo Arrellano Eduardo T Nogueira Marianne Kutschenko Adam J Moeser Jack Odle | 2013 | Journal of Animal Science and Biotechnology2013，4，3： | 17 |
