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
2Influence 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
3晶粒细化对TWIP钢力学性能与织构的影响(英文)显示文摘奥氏体高锰钢(15%-30%)呈现出孪晶诱导塑性变形机制,并在拉伸试验中表现出很好的强度-塑性性能,因此在汽车工业结构件应用中有很大潜力。最近几年,对于TWIP钢不同方面的研究受到了高度重视。之前一些综述文章关注于TWIP钢的基本知识,而非晶粒细化方法的影响。本文主要综述了通过冷轧以及强塑性变形方法引起的力学性能改善以及织构变化。基于之前的研究,通过冷轧以及强塑性变形方法,平均晶粒尺度可以急剧地减小,同时屈服强度和极限抗拉强度将会大幅升高。这个现象可以归因于变形过程引起的孪晶演化。另一方面,在冷轧变形后,Goss和Brass织构会逐步形成。王雷 BENITO J A CALVO J CABRERA J M 2016材料热处理学报2016,37,8:2
