Extract

Least cost rations for specific rates of growth in the growing and finishing periods were given to pigs slaughtered at 200 lb. live-weight. During the growing period pigs grew very close to the planned rates in spite of the fact that some food was rejected. Pigs given rations for a low growth rate in the growing period grew slightly faster than planned in the finishing period. In the finishing period pigs given rations for the high growth rate grew on average very near to this rate. The pigs given the ration for the low growth rate grew slightly faster than planned. Food conversion efficiency was for all pigs very near to, or slightly better than, that planned. The rations had no adverse effect on carcass quality.
