摘　　要：试验采用发酵床技术研究发酵床对冬季羔羊腹泻率、生长性能和血液理化指标的影响。连续进行3批试验,每批选择30只刚分娩且产双羔的杂交母羊,随机分到2栋建筑结构相同的有窗密闭舍内,一栋地面改造为发酵床(试验组),另一栋作为对照组。羔羊随母哺乳,单栏饲养7d后转出,每组随机分为3栏,转入半开放舍,继续饲养至60d断奶。结果显示,试验1~7d,试验组羔羊腹泻率显著低于对照组(P<0.05);从出生到断奶,试验组羔羊腹泻率、死亡率较对照组降低2.49%、2.95%(P<0.05)。试验7d时,试验组羔羊体高、体长和胸围分别较对照组增加1.71、0.56、0.66cm(P<0.05)。试验8~30d,试验组羔羊平均日增重较对照组提高22.59%(P<0.05);整个试验期(1~60d)内,试验组羔羊平均日增重显著高于对照组(P<0.05);60日龄时试验组羔羊体重较对照组提高13.42%(P<0.05)。试验组羔羊全血中淋巴细胞百分比显著高于对照组(P<0.05),血清葡萄糖(GLU)、总蛋白(TP)和球蛋白(GLB)含量分别比对照组提高8.45%、3.34%、10.49%(P<0.05)。研究表明,初生羔羊7d内采用发酵床饲养模式能够显著降低哺乳羔羊断奶前的腹泻率和死亡率,改善羔羊的表观消化率和血液理化指标。The experiment was used fermentation bed technology to study the effect of fermentation bed on diarrhea rate,growth performance and blood physicochemical indexes of lambs in winter.Three batches of experiments were carried out in a row,and 30 hybrid ewes who had just given birth and gave birth to two lambs in each batch were randomly assigned to two closed houses with windows and the same building structure,one floor was transformed into a fermentation bed(experimental group),and the other was used as a control group.The lambs were fed in a single pen for 7 d and then transferred out.Each group was randomly divided into three pens,transferred to semi-open houses,and continued to be fed until weaning at 60 d.The results showed that on 1~7 d,the diarrhea rate of lambs in experimental group was significantly lower than that in control group(P<0.05).From birth to weaning,the diarrhea rate and mortality of lambs in experimental group were decreased by 2.49%and 2.95%compared with control group(P<0.05).On 7 d of experiment,the body height,body length and chest circumference of lambs in experimental group were increased by 1.71,0.56,0.66 cm compared with control group,respectively(P<0.05).On 8~30 d,the average daily gain of lambs in experimental group was increased by 22.59%compared with control group(P<0.05).The average daily gain of experimental group was significantly higher than that of control group during the whole experiment period(1~60 d)(P<0.05).At 60 d of age,the body weight of lambs in experimental group was increased by 13.42%compared with control group(P<0.05).The percentage of lymphocyte in whole blood of lambs in experimental group was significantly higher than that in control group(P<0.05),and the content of GLU,TP and GLB in serum were increased by 8.45%,3.34%and 10.49%compared with control group,respectively(P<0.05).The study indicates that using a fermentation bed feeding mode within 7 d of birth can reduce the rate of diarrhea and mortality before weaning,and improve the apparent digestibility and blo
