Diurnal Rates of Feed Intake by Steers in Drylot

P. A. Putnam1, 2,, R. Lehmann3 and W. Luber4

U. S. Department of Agriculture

Abstract

An arrangement was devised to measure the amount of feed consumed and time spent by cattle at each visit to a box type feeder. Results of a study in which 25% and 89% hay rations were offered as coarsely ground mixtures or as pellets indicated that the rate of consumption varied with ration but does not vary appreciably on a diurnal basis. Therefore, the diurnal measurement of time at the feeder may be considered an accurate measure of cattle feeding patterns.
