The dependence of lean carcass composition on carcass fat, as assessed by multivariate shape/size methods
Published online by Cambridge University Press: 02 September 2010
Abstract
The relationship between the composition of the fat-free carcass and carcass fatness was studied by considering the relationship as one between two shape vectors, with the effect of size removed, using an extension of the multivariate linear least squares technique for studying multivariate allometry.
In two sets of data, one of dressed carcasses of cattle and the other of empty carcasses of lambs, the composition of the fat-free carcass (in terms of protein, water and ash) was significantly related to carcass fatness (P < 0·10 and P < 0·05 respectively). The consequences of this relationship to the study of the chemical composition of carcasses are discussed.
Examination of the relationship in more detail showed that the fatter carcasses were those with more protein and less water in their fat-free carcass, in both sets of data, and with more ash in the empty carcasses of lambs.
