Abstract
Two pairs of identical twin steers and six other adult cattle were killed, and their carcasses and tissues examined as necessary to study: (a) the muscle changes resulting from severe weight loss from starvation; (b) the reversability of such changes, as shown at various stages in recovery of the animals' weight.Decrease in the cross-sectional area of muscle following starvation was associated with reduction in muscle fibre diameter. There was no suggestion of the complete loss of any fibres; thus, with regain of live weight, recovery both of whole-muscle dimensions and muscle fibre diameter, appeared to be complete.
