A number of management and economic decisions concerning feedlot practices and length of the feeding period could be made with more precision if it were possible to predict accurately a long-term feedlot gain from a short-term observation. The results presented here are from a correlation and regression analysis of 28- and 56-day rates of gains with overall average daily gain.
