摘要

．本研究的目的是根据生长期新西兰大白兔的肩颈性状(体重、肉重和骨重)确定其胴体的组织组成。记录80只家兔的活重及解剖肉和骨组织(颈、胸、肋、腰、肩、腿)的特征。计算胴体总组织重(胴体脂肪重、胴体肉重- CMW、胴体骨重- CBW)，并进行相关和回归分析。肩、颈、肩肉、骨和颈肉与CMW和CBW相关(P < 0.0001和< 0.001)。综上所述，切重和肩颈组织含量可以很好地预测生长期新西兰大白兔的总肉重和总骨重。

Development of prediction equations to estimate carcass tissue composition in growing New Zealand White rabbits by shoulder and neck dissection

. 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.

期刊介绍： Journal of Animal and Feed Sciences (JAFS, J. Anim. Feed Sci.) has been published by the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences in Jabłonna (Poland) since 1991. It is a continuation of the Polish-language journal Roczniki Nauk Rolniczych. Seria B, Zootechniczna published by the Polish Academy of Sciences since 1969. JAFS is an international scientific journal published quarterly, about 40 papers per year including original papers, short communications and occasionally reviews. All papers are peer-reviewed and related to basic and applied researches in the field of animal breeding and genetics, physiology of nutrition, animal feeding, feed technology and food preservation. The journal distinguishes the multidisciplinary nature of physiological and nutritional sciences and so includes papers specialized in all fields connected with animal well-being, including molecular and cell biology and the emerging area of genetics.
