A note on muscle, fat and bone contents of portuguese light lamb carcasses
1999
Simoes, J.A. | Mendes, M.I.A.
A total of 72 lambs weighing between 10.1 - 13.0 kg (category C of the European Union griding for light lambs) from the Bragancano, Campanico, Merino Branco, Merino Preto e Serra da Estrela breeds were studied. These breeds represent 66,8% of the Portuguese sheep population. Evaluations were made at the same subcutaneous fat contents in the carcass (88.5 g/kg). Small, significant (p0.05) differences in the range of muscle and bone contents were found: the ranges being 30 and 25 g/kg, respectively. These variations led to significant diferences in the muscle: bone ratios, the highest value being 3.30 and the lowest 2.73. Significant differences were also found in the content of higher-priced joints (leg+chump, loin+ribs and anterior ribs) and in the proportion of kkcf (9 g/kg). No significant differences were found in the content of total fat (subcutaneous, intermuscular and kidney knob and channel fat (kkcf) and in the muscle: total fat ratios
