摘要:

试验旨在了解萨×杜×湖F1代(萨福克公羊与杜×湖母羊杂交1代)羔羊的育肥性能和肉品质效果。选用体重一致的3月龄杜×湖F1代、萨×湖F1代、萨×杜×湖F1代公羔各9只作为不同试验组,以3月龄纯繁湖羊公羔9只作为对照组,每组3个重复,每个重复3只羊。预试期10 d,正试期50 d。对照组和不同试验组育肥羔羊日粮全部参照国家肉羊饲养标准NY T/816-2004推荐的营养需要量配制。结果表明,萨×杜×湖F1代平均日增重、经济效益均极显著高于萨×湖F1代、杜×湖F1代和纯繁湖羊(P<0.01),料重比极显著低于萨×湖F1代、杜×湖F1代和纯繁湖羊(P<0.01),其中萨×杜×湖F1代的平均日增重分别比萨×湖F1代、杜×湖F1代、纯繁湖羊提高了20.89%、30.62%和47.46%,萨×杜×湖F1代的料重比分别比萨×湖F1代、杜×湖F1代、纯繁湖羊降低了21.76%、18.11%和28.72%;萨×杜×湖F1代的净肉率、肉骨比、眼肌面积极显著高于萨×湖F1代、杜×湖F1代和纯繁湖羊(P<0.01),其中萨×杜×湖F1代的净肉率分别比萨×湖F1代、杜×湖F1代、纯繁湖羊提高了2.94%、2.79%和3.92%,萨×杜×湖F1代的肉骨比分别比萨×湖F1、杜×湖F1代、纯繁湖羊提高了27.94%、6.76%和24.90%,萨×杜×湖F1代的眼肌面积分别比萨×湖F1、杜×湖F1代、纯繁湖羊提高了24.79%、24.55%和49.46%。萨×杜×湖F1代羊肉品质与萨×湖F1代、杜×湖F1代、纯繁湖羊相比表现较好,且在羊肉营养价值方面表现也较为突出。由此可见,以萨福克公羊做父本,与杜×湖F1代母羊开展三元杂交,萨×杜×湖F1代在生长速度、饲料转化率和经济效益方面效果明显,且在羊肉品质和营养价值方面表现突出,值得肉羊生产推广利用。

Abstract:

This study was aimed to understand the fattening performance and meat quality of hybridize first sheep from Sa×Du×Hu (a generation of Suffolk rams and Hu ewes).The lambs from different source were divided into three groups on average at random according to the body weight and age,nine 3-month-old hybrids first lambs of Dorper and Hu sheep (Du×Hu F1),nine 3-month-old hybrids first lambs of Suffolk and Hu sheep (Sa×Hu F1),nine 3-month-old hybrids first lambs of Suffolk and crossbred ewes F1 from Dorper and Hu sheep (Sa×Du×Hu F1) were selected to perform trial,and nine 3-month-old Hu sheep were selected as control.3 repetitions per group,3 sheep per repetition.After 10 days preliminary trial,all lambs were fed according to the nutritional requirements recommended by the national mutton sheep raising standard NY T/816-2004 in the next 50 days.The results showed that the average daily weight gain and economic benefit of Sa×Du×Hu F1 were extremely significantly higher than that of Sa×Hu F1,Du×Hu F1 and Hu sheep (P<0.01),the F/G of Sa×Du×Hu F1 were extremely significantly lower than that of Sa×Hu F1,Du×Hu F1 and Hu sheep (P<0.01),compared with Sa×Hu F1,Du×Hu F1 and Hu sheep,the average daily gain of Sa×Du×Hu F1 was increased by 20.89%,30.62% and 47.46%,the F/G of Sa×Du×Hu F1 was decreased by 21.76%,18.11% and 28.72%,respectively.The net meat ratio,meat-bone ratio and loin eye muscle area of Sa×Du×Hu F1 were extremely significantly higher than Sa×Hu F1,Du×Hu F1 and Hu sheep (P<0.01),compared with Sa×Hu F1,Du×Hu F1 and Hu sheep,the net meat ratio,meat-bone ratio and loin eye muscle area of Sa×Du×Hu F1 were increased by 2.94%,2.79%,3.92%,27.94%,6.76%,24.90% and 24.79%,24.55%,49.46%,respectively.The meat quality of Sa×Du×Hu F1 was better than Sa×Hu F1,Du×Hu F1 and Hu sheep.Furthermore,the performance of Sa×Du×Hu F1 was more prominent in nutritional value.In conclusion,the performance of Sa×Du×Hu F1 was outstanding in growth rate,feed conversion rate and economic efficiency,and was also of mutton quality and nutritional value,and the ternary crossbreeding with the Suffolk rams and Du×Hu F1 ewes was worthy of generalizing and utilizing.
