Oklahoma Agricultural Experiment Station
Abstract
A mimeographed progress report covering this paper is available as a Press Bulletin published April 30, 1932, by the Oklahoma Station.
Seven lots of eight head each of 360 pound Hereford calves were started on feed November 10, 1931, and fed for 169 days. Ground shelled corn was fed to all lots, although in one lot this was partially replaced with ground wheat. Cottonseed meal was fed to various lots to give nutritive ratios of 1:7, 1:6, and 1:4. Comparisons of alfalfa hay, prairie hay, cottonseed hulls, and darso silage were also made. Ground limestone and salt were fed in all lots. The largest and most economical gains were made by the lot fed corn, cottonseed meal, and cottonseed hulls.
The lot which received darso silage, prairie hay as a roughage, ranked second in rate of gain.
No harmful effects were noted during the course of the experiment of feeding as much as 2
pounds of cottonseed meal daily per head.
