[The nutrient and energy disposition of growing lambs. 2. Results of slaughter and animal carcass analysis].
A total of 90 lambs (fattening hybrids of either sex of three different genetic constructions and male merino meat sheep) were butchered at the beginning (9...16 kg live weight) or at the end (29...33 kg live weight) of a growth experiment. Total body and the meat of carcass, cutlet and loin were analysed. Significant differences between the genotypes could only proved in the crude ash content. The female animals showed a significantly higher content of fat, dry matter and energy as well as a significantly lower content of crude ash--at the end of the experiment also of protein--in the total body than the male animals. The content of nutrients and energy in the total body could be much more precisely derived regressively from the corresponding content values in the meat of the carcass than from the values of cutlet and loin.
