摘 要:为探究不同肉羊品种与湖羊在河西荒漠化地区的杂交效果,该试验以澳洲白绵羊、杜泊羊、无角陶赛特羊为父本,湖羊为母本开展杂交试验,按照体重相近的原则,各组合选择体质健康的羔羊20只,分成澳湖组(AH)、杜湖组(DH)和陶湖组(TH),以湖羊纯繁组(HH)为对照组,比较羔羊的生长性能、屠宰性能和肉品质,以期筛选出适宜推广应用的杂交模式。结果表明:生长性能方面,DH组和AH组F1代羔羊6月龄体重和平均日增重均显著高于HH组(P<0.05);屠宰性能方面,DH和AH组胴体重、 GR值和眼肌面积显著高于HH组(P<0.05),尾脂重低于HH组(P>0.05);肉品质方面,AH组剪切力值显著低于HH组(P<0.05),水分含量显著高于HH组(P<0.05)。可见,AH和DH组F1代羔羊生长发育快、屠宰性能高、肉品质相对较好,可作为河西荒漠化地区商品肉羊生产的杂交模式。In order to study the crossbreeding effect between different meat sheep breeds and Hu sheep in the desertification area ofHexi, this experiment used Australian white sheep, Duper sheep and Poll Dowset sheep as the male parents, and Hu sheep as the femaleparent. According to the principle of similar body weight, 20 healthy lambs were selected from each group and divided intoAoHu Group (AH), DuHu Group (DH) and TaoHu Group (TH), with the Hu sheep pure breeding group (HH) as the control group. The growth performance, slaughter performance and meat quality of lambs were compared to select a suitable hybrid model forcommercial meat sheep production in the arid desert area of Hexi. The results showed that: in terms of growth performance, bodyweight and average daily gain of the DH and AH F1 lambs at 6 months of age was significantly greater than that of the HH group(P<0.05);In terms of slaughter performance, the carcass weight, GR value, and eye muscle area of the DH and AH groups weresignificantly greater than those of the HH group (P<0.05), while tail fat weight was lower than that of HH group (P>0.05). In termsof meat quality, the shear force value of AH group was significantly lower than that of HH group (P<0.05), and the moisture contentof AH group was significantly higher than that of HH group (P<0.05). Therefore, the AH and DH F1 lambs have fast growth, highslaughter performance and relatively good meat quality, and can be promoted and applied as hybrid models for commercial meatsheep production in the desertification area of Hexi.
