Five lots of good quality Hereford steer calves, 10 head to a lot,
were used in this study. They were a part of the light end of a group
of 150 steel calves originating at Marfa, Texas, and purchased for
experimental purposes.
They were received November 8, 1951, and started on test December
22, 1951. Until they were started on test, they were fed sorghum
silage, prairie hay, and 1 pound of cottonseed cake per head daily
with free access to salt. During the experiment all were fed in drylot,
except Lot 1, which was fed out on dry bluestem pasture. All lots had
free access to a mineral mixture (bonemeal and salt) and salt during
the winter. The different lots received the following rations from
December 22,1951. to May 2, 1952:
Lot 1-Bluestem pasture and 2 pounds cottonseed cake per head daily;
Lot 2-Sorghum silage and 1 pound cottonseed cake per head daily;
Lot 3-Prairio hay and 1 pound cottonseed cake per head daily;
Lot 4-Prairie hay, 2 pounds milo grain, and 1 pound cottonseed cake
per head daily;
Lot 5-Prairie hay, 4 pounds milo grain, and 1 pound cottonseed cake
per head daily.
All lots were grazed on bluestem pasture a full season in 1952 and
sold as feeder or stocker yearlings in the fall.
A feedstuff analysis of the feeds used in the test may be found in
the back of this publication.
The final weights are full weights and should be shrunk at least
3 percent for a more complete picture of steer gain. |
