Comparative studies of meat III. Rates of fattening in relation to the percentage of muscular and fatty tissue in a carcass

Abstract

1. It has been shown in a previous paper (Callow, 1948) that, with ‘standard’ carcasses of cattle, sheep and pigs containing more than 18 % of fatty tissue, FT/C, there is a close correlation between FT/C and MT/C, the percentage of muscular tissue. This is shown by the linear regression equationMT/C = 76·1 — 0·684FT/C ± 1·0 (r= — 0·9782).The reasons for this close correlation and the effects of varying rates of fattening on the constants of the generalized equationMT/C = a — bFT/Chave been deduced by a mathematical and biological analysis of the data.
