摘要
为了评价柠条(Caragana korshinskii)、沙柳(Salix psammophila)的饲用价值,将柠条、沙柳制成颗粒饲料替代玉米(Zea mays)秸秆颗粒料饲喂小尾寒羊,分析小尾寒羊血清中生化、抗氧化和免疫指标的变化,试验共分为3组,每组30只,试验预饲期为15 d,正试期165 d。结果表明:饲喂沙柳颗粒饲料与玉米秸秆颗粒饲料相比,能显著降低血清中谷丙转氨酶(ALT)含量(P<0.05);饲喂柠条颗粒饲料与玉米秸秆颗粒饲料,可以提高小尾寒羊的抗氧化能力和显著降低血清中IL-1、IL-6和TNF-α的浓度(P<0.05)。研究结果显示,沙柳颗粒饲料在小尾寒羊日粮中应用具有可行性,有利于小尾寒羊的肝脏健康;柠条颗粒饲料饲喂小尾寒羊具有很高的开发潜力。
In order to evaluate the feeding value of Caragana korshinskii and Salix psammophila,Small-tailed Han sheep(three groups,n=30 each)were fed with pellet feed prepared from either C.korshinskii or S.psammophila and corn straw pellet feed(control)to study the effects of the different feed on serum biochemical,antioxidant,and immune indexes.The results showed that compared with corn straw pellet feed,S.psammophila pellet feed can significantly reduce the concentrations of alanine aminotransferase in serum(P<0.05);However,C.korshinskii pellet feed,compared with corn straw pellet feed,can improve the antioxidant capacity of Small-tailed Han sheep and significantly reduce the concentrations of interleukin(IL)-1,IL-6,and tumor necrosis factor alpha in serum(P<0.05).The above results show that the application of S.psammophila granules is feasible in the diet of Small-tailed Han sheep,and it is good for their liver health.Small-tailed Han sheep fed with S.psammophila have high development potential.
