Abstract

Six Kedah-Kelantan bulls and five Draughtmaster steers were used to develop a method of estimating the weights of the four carcass tissues- muscle, bone, fat and connective tissue. From an investigation of a number of non-carcass parts it was found that three measurements could be used to estimate a ll four carcass compooents. The measurements were ( a) short-cut tongue; (b) right shanks weight; (c) chilled side weight. Simple and multiple regression equations were developed to estimate the weights of muscle, bone and connective tissue in the chilled side. The most useful equations employed were short-cut tongue weight and chilled side weight to estimate total side muscle weight, and the right shanks weight to estimate both total side bone weight and total side connective tissue weight. Fat weight was estimated by an indirect method using chilled side weight and the estimates of the weights of the other three carcass components. This technique was more accurate than the fat thickness measurement at the 10th rib. Advantages of using the non-carcass parts technique are as follows All four major carcass components are predicted; no commercial loss or offals or by products occur; measurements can be taken without disrupting the abbatoir process. The additional information enables an objective assessment of carcass components.
