Summary

(1) A survey was conducted to determine the concentrate usage during the winter (1962–63) of each of 125 high-yielding dairy cows. The bulky foods consumed by each cow were also recorded.

(2) On average the cows were given 3.64 lb. concentrates per gallon of milk produced, and their intake of starch equivalent in excess of that needed for maintenance was 2.54 lb. per gallon. The margin per month (milk sales less cost of concentrates) was £14 13s Od.

(3) The implications of the results of the survey are discussed in relation to the feeding of dairy cows.
