摘　　要：试验旨在研究未破壁蜂花粉对绵羊生长性能、免疫力和经济效益的影响。试验选取体重(36.53±3.81) kg的湖羊母羊30只,随机分成5组,每组3个重复,每个重复2只羊。对照组(CK组)羊饲喂基础日粮,各试验组羊分别饲喂添加2 (A组)、5 (B组)、8 (C组)、11 g/(只·d)(D组)的未破壁蜂花粉的基础日粮。试验期40 d,其中预试期10 d,正式试验期30 d。结果显示,与CK组对比,B组湖羊平均日采食量极显著降低(P<0.01)。与CK组相比,A组湖羊血清免疫球蛋白A (IgA)含量显著上升(P<0.05),免疫球蛋白G(IgG)含量极显著上升(P<0.01);B组和C组血清IgG含量显著上升(P<0.05)。与CK组对比,A组、B组、C组和D组饲料总成本分别增加-1.29%、3.99%、17.83、31.66%,增重收益分别增加33.33%、6.67%、-6.67%和-11.79%,经济效益分别增加124.61%、13.72%、-71.23%、-126.33%。研究表明,绵羊适当饲喂未破壁蜂花粉可降低饲料投入,提升绵羊生长性能、血清免疫功能和经济效益,建议在湖羊生产添加2 g/(只·d)未破壁蜂花粉。The experiment was to investigate the effect of feeding sheep with unbroken bee pollen on growth performance,immunity and economic benefits.Selected 30 Hu sheep ewes weighing(36.53±3.81)kg and randomly divide into five groups,with three replicates in each group and two sheep in each replicate.The sheep in CK group were fed with a basic diet,the experimental groups were with fed a basic diet supplemented with 2(group A),5(group B),8(group C)and 1l g/(piece·d)(group D)of unbroken bee pollen.The trial period was 40 d,with a pre trial period of 10 d and a formal trial period of 30 d.The results showed that compared with CK group,the average daily feed intake in group B was extremely reduced(P<0.01).Compared with CK group,the serum IgA content in group A was significantly increased(P<0.05),while the IgG content was extremely increased(P<0.01),the IgG content in the serum of group B and group C significantly increased(P<0.05).Compared with CK group,the total feed cost of group A,group B,group C and group D increased by-1.29%,3.99%,17.83%and 31.66%respectively,the gain on weight increased by 33.33%,6.67%,-6.67%and-11.79%respectively,the economic benefits increased by 124.61%,13.72%,-71.23%and-126.33%,respectively.The study indicates that feeding with unbroken bee pollen appropriately can reduce feed input,improve sheep growth performance,serum immunity function and economic benefits of sheep.It is suggested to add 2 g/(piece·d)of unbroken bee pollen in Hu sheep production.
