Pigs were grown at high, moderate and low rates of gain from 20 to 55 kg and from 55 to 87 kg liveweight. Half carcasses were divided into 4 joints and each joint was dissected into bone, skin, subcutaneous fat and lean meat. The boneless tissue of each joint was analysed chemically. During the first period efficiency of feed conversion was proportional to growth rate; in the second period it depended on growth rates in both periods.
