Abstract
Data on 165 cattle have been studied statistically to determine the degree of association between the weights of the visceral organs, spleen, liver, heart, kidney and pancreas, and the weight of lean-body mass and empty-body weight. These organs were also evaluated as indicators in the estimation of empty-body weight and lean-body mass in cattle. There is a very high positive correlation between the organ weights and the weights of the empty-body and the lean-body mass. All visceral organs studied were about equally reliable in their predictive value. For a population of cattle limited in age and weight, the liver appears to be a better indicator than the other organs. With a group of cattle varying more widely in age, weight and degree of fatness all organs are good indicators. The hypothesis proposed that liver is uniquely related to lean-body mass is invalidated since other organs are also highly correlated with this factor and because this relationship is influenced largely by total or empty-body weight.
