摘    要:试验旨在研究苜蓿黄酮对绵羊生长性能和血清指标的影响。选择体重为(27.02±3.03)kg的萨福克羊×小尾寒羊杂交F1代公羊28只,采用单因素随机区组试验设计,分成4组,每组7个重复,每个重复1只。Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别在基础日粮中添加0(对照组)、0.1%、0.2%、0.4%苜蓿黄酮。预试期7 d,正试期41 d。结果表明:①日粮中添加苜蓿黄酮对绵羊生长性能无显著影响(P>0.05)。②日粮中添加苜蓿黄酮对绵羊血清中球蛋白(GLB)、天冬氨酸(ASP)、尿素氮(BUN)、高密度脂蛋白(HDL)、磷(P)含量有显著影响(P<0.05),其中Ⅲ组GLB含量在第1天时显著低于Ⅰ、Ⅱ组(P<0.05);Ⅳ组ASP含量在第1和21天时显著低于Ⅰ组(P<0.05),BUN含量在第1天时显著低于Ⅰ组(P<0.05);Ⅱ组HDL含量在第21天时显著低于Ⅰ、Ⅲ组(P<0.05);Ⅳ组P含量在第21天时显著低于Ⅱ、Ⅲ组(P<0.05)。综上所述,日粮中添加苜蓿黄酮可调节绵羊脂类代谢,提高氮的利用率;维持体内能量代谢及平衡Ca、P含量;具有潜在的促生长功能;对肝脏功能无不良影响。建议绵羊日粮中苜蓿黄酮的适宜添加量为0.2%。

Abstract:This experiment was conducted to evaluate the effect of alfalfa flavonoids (Medicago sativa) on growth performance and serum indexes of sheep.This experiment was performed with hybrid F1 sheep of Suffolk sheep×Small-tailed Han sheep.Twenty-eight sheep with the body weight of (27.02±3.03) kg were randomly divided into 4 groups with 7 replicates in each group and 1 sheep per replicate.Sheep in different groups were fed diets with 0 (group Ⅰ), 0.1% (group Ⅱ), 0.2%(group Ⅲ) and 0.4% (group Ⅳ) alfalfa flavonoids, respectively.The experiment was cosisted of 7-day-preliminary trial and 41-day-formal trial.The results showed as follows:① Dietary supplementation of alfalfa flavonoids had no significant effects on growth performance of sheep(P>0.05).② Dietary supplementation of alfalfa flavonoids had significant effects on the contents of GLB, ASP, BUN, HDL and P in serum (P<0.05).Serum GLB content at the 1st day in group Ⅲ was significantly lower than that in groupsⅠand Ⅱ(P<0.05), serum ASP contents at the 1st and 21th days in group Ⅳ were significantly lower than those in group Ⅰ(P<0.05), serum BUN content at the 1st day in group Ⅳ was significantly lower than that in group Ⅰ(P<0.05), serum HDL content at the 21th day in group Ⅱ was significantly lower than that in groups Ⅰ and Ⅲ (P<0.05), serum P content in group Ⅳ at the 21th day was significantly lower than that in groups Ⅱ and Ⅲ (P<0.05).In conclusion, dietary supplementation of alfalfa flavonoids might modulate lipid metabolism, improve nitrogen utilization, maintain energy metabolic and balance Ca and P contents, and have the potential function for promoting growth and no adverse effect on liver.The results suggested that the appropriate supplemental level of alfalfa flavonoids for sheep was 0.2%.
