摘　　要：试验研究巴克夏猪×藏猪20~65 kg、20~70 kg、20~75 kg、20~80 kg体重阶段的生长性能、胴体品质和肉质，每个体重阶段随机选择8~12头。结果表明，日增重，20~80 kg体重阶段比20~65 kg体重阶段高77.78 g（P〈0.01），20~65 kg体重阶段与20~70 kg体重阶段差异不显著；料重比，20~65 kg体重阶段、20~70 kg体重阶段与20~75 kg体重阶段之间差异不显著，都极显著低于20~80 kg体重阶段（4.69）。各个体重阶段屠宰率均在72%左右，3点平均背膘厚均在38 mm左右，胴体瘦肉率均在54%左右，肌纤维直径均在76μm左右，嫩度均在5900 g左右，肌内脂肪含量均在3.11%～3.25%，差异均不显著。综合考虑，巴克夏×藏猪杂种猪最适宜的屠宰体重为75 kg。In this paper,we made statistical analysis for fattening and carcass performance of Berkshire and Ti-betan pig＇s hybrids,which slaughtered at 65,70,75,80 kg,to explore the hybridization effect of Berkshire and Ti-betan pigs, randomly selected 8 to 12 in each of the weight stage.The result is that：the ADG at 20~80 kg is 77.78 g than at 20~65 kg weight （P〈0.01）;the ADG was not significant at the 20~65 kg weight and 20~70 kg weight;the FCR was significant increase at 80 kg weight （4.69）,which was higher than the test target,which were significant higher than all other weights;slaughter rate of each weight were about 72% or so,the average backfat thickness were about 38 mm or so,carcass lean were about 54%,muscle fiber diameter were about 76 μm,tenderness around 5 900 g,and intramuscular fat content were 3.11%~3.25%.In short,meat-performance were well.So we Inferred,this hybrid pigs optimum slaughter weight is 75 kg.
