Background： Creep feeding is used to stimulate piglet post-weaning feed consumption.L-Glutamine（GLN） is an important source of fuel for intestinal epithelial *** 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 ***（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 ***： 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% *** CFAG-AG group had the deepest（P = 0.001） crypts among all ***-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% *** reared pigs showed the greatest（P = 0.001） intestinal absorption capacity for xylose and

Glutamine and glutamate supplementation raise milk glutamine concentrations in lactating gilts

Journal of Animal Science and Biotechnology 2012年第1期3卷 25-31页

Glutamine is the most abundant amino acid in milk, and lactation is associated with increased glutamine utilization both for milk synthesis and as a fuel for the enlarged small intestine. A number of recent studies have indicated that lactation is accompanied by a mild catabolic state in which skeletal muscle proteins are degraded to provide amino acids that are used to synthesize additional glutamine. In this study we tested the hypothesis that supplemental L-glutamine or the commercially available glutamine supplement Aminogut （2.5% by weight mixed into daily feed） provided to gilts from 30 days prior to parturition until 21 days post-parturition would prevent a decrease in skeletal muscle glutamine while increasing the glutamine content of the milk. Muscle glutamine content decreased （P 〈 0.05） in control animals during lactation but this was prevented by supplementation with either L-glutamine or Aminogut. In this study, neither lactation nor supplementation had any effect on plasma glutamine or glutamate content. Free glutamine, and the total glutamine plus glutamate concentrations in milk from the control and the Aminogut group rose （P 〈 0.05） during the first 7 days of lactation, with milk concentrations in the L-glutamine supplemented group showing a similar trend （P = 0.053）. Milk glutamate remained constant between day 7 and 21 of lactation in the control and L-glutamine supplemented groups, but by day 21 of lactation the free glutamine, glutamate, and glutamine plus glutamate concentrations in milk from Aminogut-treated gilts were higher than those of control gilts. thus dietary glutamine supplementation can alleviate the fall in intramuscular glutamine content during lactation in gilts, and may alleviate some of the catabolic effects of lactation. Furthermore, the increased milk glutamine content in the supplemented gilts may provide optimum nutrition for piglet development.

Iron-Deficiency Anemia Management in Gynecological Surgery: A Review of Current Evidence and Best Practices

Open Journal of Obstetrics and Gynecology 2024年第8期14卷 1223-1241页

Purpose: Due to the high prevalence of iron deficiency anemia in women undergoing gynecological surgeries and its association with worse postoperative results, it is necessary to identify and treat anemia preoperatively. However, although anemia and iron deficiency are significant global health problems, there are still disparities in the recognition and implementation of “Patient Blood Management” (PBM) as a comprehensive approach to mitigating the risks associated with these diseases. the purpose of the study is to review best practices for the treatment of anemia based on the Enhanced Recovery After Surgery (ERAS) protocol and PBM recommendations. Methods: this study reviewed the literature on preoperative iron deficiency anemia in patients undergoing gynecological surgery. We identified references through searches in PubMed using relevant search terms. Results: Among the various strategies used in PBM, perhaps the most important is the early detection and management of anemia. In gynecological surgery, there are several approaches to reducing perioperative blood loss, highlighting the use of gonadotropin-releasing hormone (GnRH) agonists (aGnRh) and antifibrinolytics. Oral and intravenous iron supplementation can be performed in addition to blood transfusion to treat anemia. Conclusion: Addressing preoperative and postoperative anemia through systematic correction, following the guidelines of the ERAS protocol and PBM guidelines, is essential to improving perioperative outcomes in women undergoing gynecological surgery.
