STEER FATTENING TRIAL AT NORTH FLORIDA STATION

by F. S. Baker, Jr.
Assistant Animal Husbandman .

Steer fattening trials conducted since 1949 have shown the value of citrus
molasses in ground snapped corn-cottonseed meal-hay fattening rations. High levels
of citrus have consistently given better results than high levels of blackstrap
molasses ./

Adding 10 mg. per head daily of diethylstilbestrol to the ration has increased
steer gains aDproximately 12 percent with a 5 percent saving in feed cost per 100
pounds gain./

Because of the need for comparing low levels of citrus and blackstrap molasses,
with and without stilbestrol, a feeding trial was conducted in which the following
rations were fed:

Lot 1. Ground snapped corn, c. s. meal, hay.
Lot 2. Ground snapped corn, c. s. meal plus stilbestrol, hay.
Lot 3. Ground snapped corn, 5 lbs. blackstrap molasses, c. s. meal, hay.
Lot 4. Ground snapped corn, 5 lbs. blackstrap molasses, c. s. meal plus
stilbestrol, hay.
Lot 5. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal, hay.
Lot 6. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal plus
stilbestrol, hay.
Antibiotics (terramycin and aureomycin) apparently did not improve results
in one trial at this Station in which thrifty, growth feeder steers were fed to
the good and choice grades.2

To obtain further data on antibiotics, the following rations were tried:

Lot 6. Ground snapped corn, 5 Ibs. citrus molasses, c. s. meal plus
stilbestrol, hay.
Lot 7. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal plus
stilbestrol and terramycin, hay.
Lot 8. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal plus
stilbestrol and aureomycin, hay.
Since silage production is increasing in North Florida, it was also considered
advisable to try silage in the fattening ration. The following rations were fed:

Lot 6. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal plus
stilbestrol, hay.

Lot 9. Ground snapped corn, 5 lbs. citrus molasses, c. s. meal plus
stilbestrol, 15-20 lbs. grain sorghum silage..first part '6f feeding
period, hay last part of period.
Lot 10. Ground snapped corn, 5 lbs. citrus molasses, c. a. meal plus
stilbestrol, 15-20 lbs. grain sorghum silage.

Good quality Hereford yearling feeder steers were purchased on the Oklahoma
City market for this trial.

RESULTS

Results of the comparison of low levels of citrus, blackstrap, and no molasses,
with and without stilbestrol, are shown in Tables 1-580, 2-580, and 3-580. It will
be seen that at the level of 5 pounds per head daily which was fed in this trial,
blackstrap molasses produced slightly larger gains and comparable carcass grades to
citrus molasses. As previously stated, blackstrap had not compared ver favorably
with citrus molasses when both were fed at higher levels in the ration.-/ It should
also be noted that either 5 pounds of blackstrap or 5 pounds of citrus molasses
improved steer gains, grades, and carcass yields when compared with rations contain-
ing no molasses. Feeding these levels of molasses did not result in a saving in
feed cost per 100 pounds gain, which indicates that the prices paid for the molasses
were about as high as a feeder could afford to pay at the present price of corn.

Feeding 10 mg. stilbestrol resulted in an average increase in gain of approxi-
mately 15 percent and a saving of about 10 percent in feed cost per 100 pounds gain
(Table 2-580). Experimental error probably explains the fact that the cattle not
fed molasses (Lot II) did not respond to stilbestrol (Table 1-580), As shown in
Table 2-580, there was no difference in grade and yield of the cattle fed stilbestro3
and those not getting the drug.

Results of the antibiotic feeding are given in Table 4-580. There was not
much difference in steer gain between Lots VI, VII, and VIII; however, the steers
fed the antibiotics (Lots VII and VIII) graded and yielded slightly higher. Because
of the small numbers involved, results from this one trial should not be considered
conclusive, especially since these results do not agree too closely with those from
a preceding trial.2-

Feeding moderate quantities of grain sorghum silage apparently did not result
in lower gains, grades or carcass yields (Table 5-580). There was, however, no
saving in feed cost from feeding the silage. In this trial silage was added to the
ration in increasing amounts as long as grain did not have to be severely limited to
force the cattle to eat the silage. A level of 20 pounds of silage per head daily
was found to be about the amount the cattle would eat without a marked reduction in
the grain allowance.

SUMMARY

Adding 5 pounds of blackstrap or 5 pounds of citrus molasses per steer daily
to a ration of ground snapped corn, cottonseed meal, and hay resulted in increased
gains and higher carcass grades and yields. With ground snapped corn at $35 per ton
citrus molasses at $27.50 and blackstrap molasses at $30, adding the molasses did
not lower the cost of feed per 100 pounds gain.

I/ See footnote 1, page 1
2/ See footnote 2, page 1








Feeding 10 mg. stilbestrol per head daily increased steer gains about 15
percent at a saving in feed cost per 100 pounds gain of approximately 10 percent.

Feeding moderate amounts of grain sorghum silage (15 to 20 pounds per head
daily) did not reduce steer gains, grades, or carcass yields but neither did the
silage feeding result in a saving in feed cost.

ACKNOWLEDGEMENTS

This trial was supported in part by Eli Lilly & Co., Indianapolis, Ind.,
Chas. Pfizer & Co., Terre Haute, Ind., and American Cyanamid Co., Fine Chemicals
Division, New York, N. Y.

Suber-Edwards Packing Company, Quincy, arranged to slaughter the cattle so
that carcass data could be obtained.
