ABSTRACT

The objective of this study was to determine the tissue composition of the carcass of growing New Zealand White rabbits based on the shoulder and neck traits (weight, meat and bone weights). Live weight and characteristics of dissected meat and bone tissues (neck, breast, rib, loin, shoulder, and leg) of 80 rabbits were recorded. Total carcass tissue weights (carcass fat weight, carcass meat weight – CMW, and carcass bone weight – CBW) were calculated and correlation and regression analyses were implemented. Shoulder, neck, shoulder meat, bone and neck meat were correlated (P < 0.0001 and < 0.001) with CMW and CBW. In conclusion, cut weights and tissue content of the shoulder and neck provided good predictions for total meat and bone weights of growing New Zealand White rabbits.

通过肩颈解剖对新西兰大白兔胴体组成的评价及预测方程的建立

摘要: 本研究的目的是根据肩颈解剖性状（重量、肉重和骨重）来确定生长中的新西兰大白兔的胴体组成。试验记录了80只兔的活重及肌肉和骨骼组织、颈、胸、肋骨、腰、肩、腿）的解剖性状，计算胴体组织总重量（胴体脂肪重 (Carcass fat weight) CFW、胴体肉重 (Carcass meat weight) CMW、胴体骨重 (Carcass bone weight， CB)，并进行相关和回归分析。结果显示，肩重 (Shoulder、SW)、颈重 (Neck，NW) 、肩肉重 (Shoulder meat，SM)、肩骨重 (Shoulder bone SB) 和颈肉重 (Neck meat，NM) 与胴体肉重 (P < 0.0001) 和胴体骨重 (P < 0.001) 呈显著正相关。综上所述，肩部和颈部的重量和组织含量可以很好地预测新西兰白兔的总肉重和骨重。
