| 摘 要： | 本试验旨在研究丙氨酰谷氨酰胺二肽(Ala-Gln)对早期断奶仔猪抗氧化能力和肠道保护的影响。采用完全随机化设计,选用体质量、胎次、泌乳量、产仔数相近、健康的云南撒坝母猪所产的48头仔猪(1/2♂,1/2♀),35日龄断奶,随机分成4个处理,每个处理3个重复,每个重复4头。A组为对照组,饲喂基础日粮,B、C和D组分别饲喂添加0.15%、0.30%和0.45%Ala-Gln的试验日粮。试验期为35~60日龄。结果表明,添加0.15%、0.30%和0.45%Ala-Gln可提高断奶仔猪生长性能,随饲粮Ala-Gln添加水平提高,日采食量、体质量呈二次曲线上升(P<0.05),料重比呈二次曲线降低(P<0.05)。第49日龄的仔猪血清T-AOC和T-SOD含量以二次曲线方式升高(P<0.05),血清MDA活性呈二次曲线降低(P<0.01)。小肠形态学观察结果显示,仔猪十二指肠和回肠绒毛长度以二次曲线方式升高(P<0.01),空肠绒毛长度以二次曲线方式升高(P<0.05),十二指肠和空肠隐窝深度以二次曲线方式降低(P<0.05),十二指肠、空肠和回肠绒毛长度和隐窝深度比值(V/C)以二次曲线方式提高(P<0.01)。结...

| Abstract: | This experiment was conducted to investigate the effects of Alany-glutamine(Ala-Gln) on antioxidant ability and protecting intestine of early weanling piglets.48 piglets of weanling at 35 days(half male,half female),reproduced by Yunnan Saba sows with similar body weight,parity,milk yields and litter size,were designed randomly to 4 groups,each has 3 repeats with 4 piglets per repeat.Group A(control) was fed the basal diet,and experimental diets with adding 0.15%,0.30% and 0.45% for group B,C and D,respecti... |
