摘　　要：腐植酸钠饲料添加剂作为一种新型绿色、低成本、高效益的添加剂,在国内外已广泛研究应用于畜牧兽医领域,武威市在腐植酸钠应用畜牧养殖业领域的示范尚在初始期。本试验结合养殖场项目实施,通过在同日龄下羔羊日粮精饲料中添加0.5%、1%、2%、4%比例腐植酸钠饲喂,跟踪检测抗体消减情况,掌握并对比试验羔羊免疫保护期长短、疾病治疗用药、免疫功能调节情况。结果表明,在同等管理条件下饲喂羔羊后,各试验组羔羊抗体水平比对照组明显提高且保护期延长,效果显著(P<0.05),在1%、2%、4%含量下,羔羊疫苗免疫抗体水平在4个月时仍在90%以上,且在1%、2%时用药治疗费最少,腹泻等肠道疾病明显改善;随着腐殖酸钠水平的增加,羔羊免疫指标较对照组逐渐提高,羊只血液中免疫球蛋白IgG、IgA含量逐渐增加,这表明添加相对高水平的腐殖酸钠比低水平的更能提高绵羊免疫功能。在当前国内推行健康无抗养殖新形势下,可广泛推广应用。Sodium humate feed additive is a new green,low-cost and high-efficiency additive.This has been widely studied and applied in the field of animal husbandry and veterinary medicine at home and abroad.Wuwei City’s demonstration of the application of sodium humate in the field of animal husbandry is still in its initial stage.This test was implemented in conjunction with the farm project.By adding 0.5%,1%,2%,and 4% sodium humate to the dietary concentrates of lambs of the same age,the antibody reduction situation was tracked and detected,and the immunity of the test lambs was understood and compared.The length of protection period,disease treatment medications,and immune function regulation.The results showed that after feeding lambs under the same management conditions,the antibody levels of lambs in each test group were significantly higher than those in the control group and the protection period was extended,with significant effects(P<0.05).At 1%,2%,and 4%,the immune antibody level of the lamb vaccine was still above 90%at 4 months,and at 1% and 2%,the cost of drug treatment was the least,and intestinal diseases such as diarrhea were significantly improved.As the sodium humate level increased,the immune indicators of the lambs gradually improved compared with the control group,and the immunoglobulin IgG and IgA contents in the blood of the sheep gradually increased.This suggests that adding relatively high levels of sodium humate can improve sheep immune function more than low levels.Under the current new situation of promoting healthy and antibiotic-free breeding in China,it can be widely promoted and applied.
