2014年哈密地区开展了萨福克羊冻胚移植,笔者选择三个养殖场部分胚胎移植萨福克羊进行跟踪调查,从初生重、3月龄、6月龄、12月龄体重及体尺进行测定,收集相关数据结果显示:A、B、C场初生重差异不显著(P>0.05),3月龄C场公羔体斜长与胸围差异均显著(P<0.05);数据表明:在营养较好的条件下,萨福克公羔生长速度快;6月龄C场与A场、B场公羔相比较体重、胸围差异均显著(P<0.05);12月龄A、C场公、母羊体重及体尺与B场公、母羊体重及体尺差极异显著(P<0.01)。A、B、C场羊只冬春季脉搏稍高于夏秋季,冬春季体温、脉搏、呼吸频率与夏秋季无差异(P>0.05)。萨福克育成羊繁殖率均在125%以上,接近于原产地水平,具有良好的繁殖性能。在饲养管理差的情况下,易患呼吸道疾病、异食癖时有发生,出现生长受阻。结果表明:在饲养条件良好环境下生长发育良好,生理指标正常,抗病力强,适应性好。

In 2014, frozen embryo transfer of Suffolk sheep was carried out in Hami area. The author follows up and investigates some relevant sheep in three livestock farms which are named as A, B and C, by measuring their weight and length respectively from birth weight, 3 months age, 6 months age and 12 months age, collecting relevant data, and finds that the birth weight of the three farms is similar(P >0.05), the difference of slanting length and chest circumference of rams with 3 months age in Farm C is significant(P<0.05). By the aforesaid data, it indicates that Suffolk rams grow quickly under good nutritional conditions;compared with rams with 6 month age in Farm A and B, the ones in Farm C with quite different weight and chest circumference(P<0.05); rams and ewes with 12 months age in Farm A and C are quite different from the ones in Farm B(p<0.01). The pulse of sheep in the three farms in Spring and Winter is slightly higher than that in Autumn and Fall, and body temperature, pulse, respiratory rate and Scomber australasicus are with no difference in the four seasons(P > 0.05). Suffolk bred sheep breeding rate is above 125%, close to the level of original place with good reproductive performance. In resistance of disease: under poor conditions,they are easy to suffer from respiratory disease and allotriophagia which restrict growth. Therefore, the sheep can grow well with normal physiological indicators, strong disease resistant and adaptability under good feeding conditions.
