Extract

Complete chemical analyses of all body components of 20 Large White pigs were carried out. At the average live-weight of 90·3 kg. (empty body weight 86·5 kg.) the total protein content was found to be 12·7 kg. and that of the chemical fat 25·4 kg. The edible parts of the carcass (i.e. lean and separable fat) contained only 58·5% (range 55·2–61·3) of the total protein but as much as 85% of the total chemical fat. Simple and multiple correlations were computed between various carcass characters and protein, chemical fat and energy content. The results indicate that it may be possible to obtain fairly accurate estimates of the chemical composition and energy content of the edible parts of the carcass, of the whole carcass, and of the empty body by methods based on various systems of assessing the carcass quality.
