HEREFORD AND BLACK WHITE FACE STEERS ON SELF-FED FATTENING RATIONS

The feedlot performance of Hereford and Angus x Hereford crossbred steers on self-fed fattening rations has been compared over a three year period.

The feeding period in 1973 extended from February 2 until November 19, a total of 308 days. In 1974 the 340 day feeding period was from November 1, 1973 and October 7, 1974, and in 1975 the 314 day feeding period was from November 19, 1974 to September 29, 1975.

During the feeding period, oats in the ration was replaced by barley as shown in the following table.

Table 21 - Composition of self-fed ration by weight for the feeding period November 19, 1974 to September 29, 19751
Ration of 5% alfalfa - 20% tame hay
November 19 - November 30 25% oats, 75% hay
December 1 - January 6 50% oats, 50% hay
January 7 - February 24 65% oats, 25% hay, 10% barley
February 25 - April 10 50% oats, 25% hay, 25% barley
April 11 - June 4 40% oats, 25% hay, 35% barley
June 5 - September 29 30% oats, 25% hay, 45% barley
1All lots received minerals at the rate of 10 pounds di-calcium phosphate and 20 pounds granulated salt, added to 1000 pounds of mixed feed for the first two months, after which the di-calcium phosphate was reduced to 5 pounds.

Summary: Results of feeding trials over a three period show that Herefords and Hereford-Angus crossbreds performed equally well on the self fed rations used. While there are statistically significant differences in gain during the period, no difference is shown in the net profit realized.
