1Effects 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 2013Journal of Animal Science and Biotechnology2013,4,3:17

3Acute effects of rotavirus and malnutrition on intestinal barrier function in neonatal piglets显示文摘AIM: To investigate the effect of protein-energy malnutrition on intestinal barrier function during rotavirus enteritis in a piglet model.METHODS: Newborn piglets were allotted at day 4 of age to the following treatments:(1) full-strength formula(FSF)/noninfected;(2) FSF/rotavirus infected;(3) half-strength formula(HSF)/noninfected;or(4) HSF/rotavirus infected.After one day of adjustment to the feeding rates,pigs were infected with rotavirus and acute effects on growth and diarrhea were monitored for 3 d and jejunal samples were collected for Ussingchamber analyses.RESULTS: Piglets that were malnourished or infected had lower body weights on days 2 and 3 post-infection(P < 0.05).Three days post-infection,marked diarrhea and weight loss were accompanied by sharp reductions in villus height(59%) and lactase activity(91%) and increased crypt depth(21%) in infected compared with non-infected pigs(P < 0.05).Malnutrition also increased crypt depth(21%) compared to full-fed piglets.Villus:crypt ratio was reduced(67%) with viral infection.There was a trend for reduction in transepithelial electrical resistance with rotavirus infection and malnutrition(P = 0.1).3H-mannitol flux was significantly increased(50%;P < 0.001) in rotavirus-infected piglets compared to non-infected piglets,but there was no effect of nutritional status.Furthermore,rotavirus infection reduced localization of the tight junction protein,occludin,in the cell membrane and increased localization in the cytosol.CONCLUSION: Overall,malnutrition had no additive effects to rotavirus infection on intestinal barrier function at day 3 post-infection in a neonatal piglet model.Sheila K Jacobi Adam J Moeser Anthony T Blikslager J Marc Rhoads Benjamin A Corl Robert J Harrell Jack Odle 2013World Journal of Gastroenterology2013,19,31:4

5Influence of birth order, birth weight, colostrum and serum immunoglobulin G on neonatal piglet survival显示文摘Background: Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG). The birth order and weight of 745 piglets (from 75 litters) were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Results: Sow parity had a significant (P < 0.001) effect on sow colostral IgG concentration, being 5% higher in multiparous females. Sow colostral IgG concentration explained 6% and piglet birth order accounted for another 4% of the variation observed in piglet serum IgG concentration (P < 0.05); however, birth weight had no detectable effect. Piglet serum IgG concentration had both a linear (P < 0.05) and quadratic effect (P < 0.05) on % survival. Piglets with 1,000 mg/dl serum IgG or less (n=24) had a 67% survival; whereas, piglets with IgG concentrations between 2250 to 2500 mg/dl (n=247) had a 91% survival. Birth order had no detectable effect on survival, but birth weight had a positive linear effect (P < 0.05). Piglets weighing 0.9 kg (n = 107) at birth had a 68% survival rate, and those weighing 1.6 kg (n = 158) had an 89% survival. Conclusion: We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.Rafael A Cabrera Xi Lin Joy M Campbell Adam J Moeser Jack Odle 2013Journal of Animal Science and Biotechnology2013,4,2:2

7Survival after inflammatory bowel disease-associated colorectal cancer in the Colon Cancer Family Registry显示文摘AIM: To investigate the survival of individuals with colorectal cancer (CRC) with inflammatory bowel disease (IBD-associated CRC) compared to that of individuals without IBD diagnosed with CRC. METHODS: Epidemiologic, clinical, and follow-up data were obtained from the Colon Cancer Family Registry (Colon CFR). IBD-associated cases were identified from self-report of physician diagnosis. For a subset of participants, medical records were examined to confirm self-report of IBD. Cox proportional hazards regression was applied to estimate adjusted hazard ratios (aHR) and 95%CI of mortality, comparing IBD-associated to non-IBD-associated CRC, adjusted for age at CRC diagnosis, sex, Colon CFR phase, and number of prior endoscopies. Following imputation to complete CRC stage information, adjustment for CRC stage was examined. RESULTS: A total of 7202 CRC cases, including 250 cases of IBD-associated CRC, were analyzed. Over a twelve year follow-up period following CRC diagnosis, 2013 and 74 deaths occurred among non-IBD associated CRC and IBD-associated CRC patients, respectively. The difference in survival between IBD-associated and non-IBD CRC cases was not statistically significant (aHR = 1.08; 95%CI: 0.85-1.36). However, the assumption of proportional hazards necessary for valid inference from Cox regression was not met over the entire follow-up period, and we therefore limited analyses to within five years after CRC diagnosis when the assumption of proportional hazards was met. Over this period, there was evidence of worse prognosis for IBD-associated CRC (aHR = 1.36; 95%CI: 1.05-1.76). Results were similar when adjusted for CRC stage, or restricted to IBD confirmed in medical records. CONCLUSION: These results support the hypothesis that IBD-associated CRC has a worse prognosis than non-IBD-associated CRC.Scott V Adams Dennis J Ahnen John A Baron Peter T Campbell Steven Gallinger William M Grady Loic LeMarchand Noralane M Lindor John D Potter Polly A Newcomb 2013World Journal of Gastroenterology2013,19,21:2
