摘要

本试验旨在研究母猪饲粮添加甜菜碱对巴马香猪哺乳仔猪血液指标的影响。选取3~7胎次妊娠巴马香猪40头，随机分为2组，每组20头，单栏饲养。对照组饲喂基础饲粮，试验组在基础饲粮中添加3.5 kg/t甜菜碱。试验期为母猪配种后第3天至分娩后第21天。试验结束时，从每组随机选取10窝仔猪，每窝选取1头仔猪采血，测定血浆激素含量、抗氧化指标和游离氨基酸含量。结果表明：与对照组相比，甜菜碱组哺乳仔猪血浆胆囊收缩素（CCK）、酪酪肽（PYY）、瘦素（LEP）、丙二醛（MDA）、过氧化氢（H2O2）和丙氨酸（Ala）含量显著降低（P<0.05），血浆鹅肌肽（Ans）、1-甲基组氨酸（1-MeHis）和3-甲基组氨酸（3-MeHis）含量显著升高（P<0.05），血浆苏氨酸（Thr）（P=0.069）、谷氨酸（Glu）（P=0.055）和肌肽（Car）（P=0.055）含量呈下降趋势，血浆亮氨酸（Leu）含量呈升高趋势（P=0.069）。综上所述，母猪饲粮添加甜菜碱可降低哺乳仔猪血浆摄食相关因子水平，减弱机体的氧化水平，改变血浆游离氨基酸含量，有利于仔猪的生长发育与机体健康。

Abstract

This study was conducted to determine the effect of betaine supplementation in sow diets on blood indexes of suckling Bama mini-pigs. Forty pregnant Bama mini-pigs with 3 to 7 parities were randomly divided into two groups with 20 sows per group, and fed individually. Pigs in the control group were fed a basal diet, while others in the experimental group were fed the basal diet supplemented with 3.5 kg/t betaine hydrochloride. The trial period was from day 3 after mating to postpartum day 21. At the end of experiment, ten litters of piglets were randomly selected from each group, and 1 pig in each litter was selected for blood collection, the plasma hormone contents, antioxidant indexes and free amino acid contents were determined. The results showed that compared with the control group, the contents of cholecystokinin (CCK), peptide YY (PYY), leptin (LEP), malondialdehyde (MDA), hydrogen peroxide (H2O2) and alanine (Ala) in plasma of suckling piglets of betaine group were significantly decreased (P<0.05), the contents of anserine (Ans), 1-methyl histidine (1-MeHis) and 3-methyl histidine (3-MeHis) in plasma were significantly increased (P<0.05), the contents of threonine (Thr) (P=0.069), glutamate (Glu) (P=0.055) and carnosine (Car) (P=0.055) in plasma were presented a decreased tendency, and the plasma leucine (Leu) content was presented an increased tendency (P=0.069). In conclusion, the betaine supplementation in sow diets can decrease the plasma ingestion related factor level of suckling piglets, reduce the body's oxidant level, and alter the plasma free amino acid contents, which is beneficial to the growth, development and health of piglets.
