Glutamine and glutamate supplementation raise milk glutamine concentrations in lactating gilts

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.

Journal of animal Science and Biotechnology 2018年第1期9卷 24-34页

The demand for duck meat, duck eggs, and associated products is increasing each year. Classic and modern selection programs have been applied to enhance the economic traits of ducks to satisfy the requirements of consumers and enhance the incomes of producers. The nutritional requirements of unselected ducks may not be adequate, however, to fulfill the potential productivity performance of modern birds, including both meat-type and egg-type ducks. In particular, an imbalanced diet is associated with low productive performance and signs of nutritional deficiency（if insufficient nutrients are supplied）, as well as with high feed costs and manure problems that reflect flock health and welfare（if excessive nutrients are supplied）. Thus, the main aim of this review is to summarize the results of previous studies that estimated the nutrient requirements of meat-type and egg-type ducks in order to evaluate current knowledge and to identify further issues that need to be addressed. In addition,the results obtained in previous studies are compared in order to understand how to lower commercial feed costs,fulfill the genetic potential of selected ducks, protect the environment from pollution, and satisfy the welfare and health needs of ducks.

Journal of animal Science and Biotechnology 2017年第1期8卷 119-127页

作者： Huizeng Sun Bing Wang Jiakun Wang Hongyun Liu Jianxin Liu Institute of Daiw Science，MoE Key Laboratory of Molecular animal nutrition College of animal Sciences，Zhejiang University Hangzhou 310058 People's Republic of China

Background： Alfalfa hay and corn stover are different type of forages which can significantly impact a cow＇s lactation performance, but the underlying metabolic mechanism has been poorly studied. We used biomarker and pathway analyses to characterize related biomarkers and pathways based on urine metabolomics data from different forage treatments. Urine was col ected from 16 multiparous Holstein dairy cows fed alfalfa hay（AH, high-quality forage, n = 8） and corn stover（CS, low-quality forage, n = 8） respectively. Gas chromatography–time of flight/mass spectrometry（GC-TOF/MS） was performed to identify metabolites in urine and the metaboanalyst online platform was used to do biomarker and pathway ***： Hippuric acid（HUA） and N-methyl-glutamic（NML-Glu） indicated the most significant difference between the two diets, when statistical y validated by biomarker analysis. HUA was also validated by standard compound quantitative method and showed significant higher concentration in CS group than AH group（2.8282 vs. 0.0005 mg/mL; P 〈 0.01）.The significant negative correlation between milk yield and HUA（R^2= 0.459; P 〈 0.01） and significant positive correlation between milk yield and NML-Glu（R^2= 0.652; P 〈 0.01） were characterized. The pathway analysis revealed that these different metabolites were involved in 17 pathways including 7 influential pathways（pathway impact value 〉 0）： Tyr metabolism, starch and sucrose metabolism, amino sugar and nucleotide sugar metabolism, galactose metabolism,Phe, Tyr and Try biosynthesis, purine metabolism, and glycerolipid metabolism. Based on the metabolome view map,the Phe, Tyr and Try biosynthesis pathway exhibited the highest impact value（0.50）, and the Holm-Bonferroni multiple testing-based analysis revealed the most significant difference in the Tyr metabolism pathway（Holm P = 0.048）.Conclusions： The identified HUA and NML-Glu may serve as potential biomarkers for discriminating CS and AH diets and could be used as candidat
