Abstract
A series of seven summer pasture finishing trials with beef steers was conducted to study the effect of adding various types and levels of protein supplements with a full feed of corn on beef cattle performance. Starting weights (approximately May 15) for the cattle ranged from 485 (220 kg) to 693 lb (315 kg) and the trials extended for 176 to 196 days, at which time the cattle were of slaughter finish. They had gained from 470 lb (214 kg) to 560 lb (255 kg). An all natural protein supplement (Purdue Supplement A), when incorporated at 5% or 10% of the grain mix, resulted in significant (P<.01) increases in gain. In two of four experiments, Supplement A was superior to Purdue 64 Supplement (high urea) as indicated by significantly (P<.01) increased gains. In three of five comparisons the addition of 5% of a high urea supplement (Purdue 64) resulted in significant (P<.05) increases in daily gain. Liquid 64 and liquid 40 (high urea liquid supplements) were without apparent benefit in supplementing a corn and pasture finishing diet. A biuret supplement offered on an ad libitum basis also was without benefit. Whole and rolled shelled corn comparison gave comparable gain and feed efficiency figures in three comparisons. One acre of pasture saved a calculated average of one metric ton of grain. Copyright © 1976. American Society of Animal Science . Copyright 1976 by American Society of Animal Science.
