Summary

The body composition of 24 pigs reared at different rates of growth from 25 kg live weight was estimated when they each weighed about 90 kg live weight. Feed conversion corrected for the energy requirements of maintenance (CFCR), external and ultrasonic measurements, and measurements of Evans Blue, deuterium oxide and potassium-42 were applied simultaneously to each pig, and were used to predict the weights of the fat-free mass, lipid, and dissectible fat and lean.

The best individual predictors of body composition were CFCR, deuterium oxide and potassium-42, but Evans Blue, external and ultrasonic measurements were not as closely associated with the four body components.

In combination, it was generally found that two predictors could predict the weight of a body component more closely than either predictor in isolation.
