       在以前的研究中，日粮补充缬氨酸可提高母猪生产性能，它可能与免疫系统和内分泌功能的改善有关系。32头健康母猪（长白x约克夏，胎次和身体状况差不多）被分配到四个日粮组之中的一组：基础日粮（0.93％赖氨酸，缬氨酸0.84％）或者基础日粮中分别添加0.10％，0.25％和0.40％的缬氨酸，从妊娠107天到哺乳期第21天添加。在哺乳期第10和18天的收集血液样品，在哺乳期第1和10天采集奶水。
　　结果表明，日粮补充缬氨酸明显地增加了哺乳期第10和18天的血清白蛋白浓度（P <0.05），第18天的血清免疫球蛋白M，免疫球蛋白G和催乳素浓度增加了（P <0.05）。补充缬氨酸使得哺乳期第14天奶水中的胰岛素浓度也显着增加（P<0.05），并增加了哺乳期第1和14天奶水中生长激素的浓度。日粮补充缬氨酸易于增加乳白蛋白和IgM浓度（P> 0.05），这往往会降低乳猪的腹泻率（P>0.05）。
　　因此，有人建议，日粮补充缬氨酸，母猪获得更好的性能可能主要与母猪免疫功能改善以及奶源性生长因子浓度提高有关。

英文原文：　　In previous study, dietary valine supplementation improved sow performance, it may be related to immune and endocrinology function improvement. Thirty-two healthy sows (Landrace x Yorkshire, similar parity, and body condition) were assigned to fed one of the four diets: basal diet (0.93 % Lysine, 0.84 % Valine) or basal diet supplemented with 0.10 %, 0.25 %, and 0.40 % valine respectively from 107 days of gestation to 21 days of lactation. Blood samples were collected at 10 and 18 days of lactation, milk samples were collected at 1 and 10 days of lactation.

　　The results showed that dietary valine supplementation significantly increased serum albumin concentrations at 10 and 18 days of lactation (P<0.05), and increased serum Immunoglobulin M, Immunoglobulin G and Prolactin concentrations at 18 days (P<0.05) of lactation. Valine supplementation also significantly increased milk insulin concentrations at 14 days of lactation (P<0.05), and increased milk growth hormone concentrations at 1 and 14 days of lactation. Dietary valine supplementation tended to increase milk ALB and IgM concentrations (P>0.05) and tend to reduce diarrhoea rate in suckling pigs (P>0.05).

　　Therefore, it was suggested that better performance of sows fed valine supplemented diet could be mainly related to improved sows’ immune function and increased milk-borne growth factors concentrations.
