The objectives of this thesis ~ Present feed production was obtained from published data . Livestock feed requirements were calculated using factors published in Lives tock- Feed Relationships, a publication of the United States Department of Agriculture. The projections of feed requirements to 1980 were made by projecting livestock numbers based on a least squares analysis of past trends. Utilizing the projected numbers permits calculation of t he feed requirements. Feed production in 1980 was obtained by projecting past feed production and by applying least squares analysis to obtain a predicting equation that allows projection to 1980. Separate predictions were made for roughage and feed grains. Utah will have a feed grain deficit totaling about 407,000 tons in 1980. The state will have an estimated roughage surplus ranging from about 250 , 000 tons to 825,000 t ons depending on the base period selected.
