Relationships between beef carcass shape and muscle to bone ratio.

摘要: Relationships between muscularity and muscle to bone ratio were investigated for beef carcasses of several breeds crosses, three genders using data from Bristol Alberta. Side dissection in terms muscle, fat weights used calculate ratios (MtoB) indexes (MUSC) the whole side or region around femur bone. Highly significant breed gender effects on MtoB MUSC shown both Alberta sets, but group differences not same as those despite fact that these two characteristics closely correlated. For sets data, example, values at a common plus weight significantly higher bulls than heifers, similarly adjusted generally heifers bulls. Differences among groups mainly similar direction MtoB, size varied widely. relative Friesian, Jersey had lower MUSC, double-muscled femur-region was 19.2% greater Shorthorn-cross carcasses, only 1.7% higher. These findings show because inconsistent relationships different classes lean meat yield cannot always be predicted without bias if measures carcass shape are indicators ratio.
