Summary A compilation from figures published by the United States Department of Agriculture gives the average feed received by 118 bulls on farms in four sections of the United States. In addition 37 hours man-labor were required, pasture to the amount of $6.57, and other cost totaling $28.37. A summary is given of the feed received by 58 bulls of Minnesota farms over a period of a year. The average feed cost at current local prices was $69.71. Assuming the same other costs as found by the United States Department of Agriculture, the total cost of keeping a mature bull is approximately $98.00 a year in addition to about 37 hours of man labor. The amount of feed consumed by six mature bulls in the University of Minnesota herd is given. The total digestible nutrients contained approximate closely the maintenance requirements as estimated by the use of feeding standards. The nutrients received by growing bulls fed according to common practice on dairy farms were close to the amounts prescribed by Morrison's feeding standard for growing dairy cattle of the weights represented.
