CITRUS MOLASSES, DRIED CITRUS PULP, CITRUS MEAL, BLACKSTRAP
MOLASSES, AND STILBESTROL IN STEER FATTENING RATIONS.

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

Previous steer fattening trials have shown the value of adding citrus
molasses to fattening rations.1 Molasses has usually been cheaper per ton
than corn, and in addition where poor quality roughage was fed, adding citrus
molasses stimulated feed consumption.

Blackstrap molasses has not given as good results as citrus,1 but because
of its availability, work with limited quantities of blackstrap in the ration
seems advisable.

Rations containing limited quantities of dried citrus pulp and citrus
meal produced economical gains in one fattening trial.1 Use of these feeds as
corn substitutes seems possible when they are somewhat cheaper than snapped corn.

Diethylstilbestrol is widely used in fattening rations. Because of the
favorable results with this material elsewhere,2 it seemed advisable to try it
in fattening rations fed in this area.
PROCEDURE

Good quality Hereford steers were used. These cattle grazed improved
pasture prior to being placed in the feedlot, and most would have graded "U. S.
Commercial" when started on feed. After a short preliminary period during which
the cattle were allotted and placed on experimental rations, the steers were
weighed and 3 percent was deducted to obtain the initial weights. At completion
of the experiment, the cattle were picked-up in the morning before feeding, trucked
to Quincy, weighed, and 3 percent deducted to obtain the final weights. Thus the
initial weights were shrunk 3 percent and final weights about 4 percent (including
actual shrink in trucking to market) from feedlot weights.

Steers were slaughtered at Florida Packing Company in Quincy when they
attained a satisfactory finish.
RESULTS

Results of the fattening trial are given in Tables 1 to 3-580.

Stilbestrol in fattening ration.-- Stilbestrol was tried at levels of 10 mg.
and 20 mg. per head daily in a ration consisting of ground snapped corn and citrus
molasses, cottonseed meal, and hay. The 10 mg. level is the recommended rate

4eove4 by the Food And Drug Administration.
Steers fed stilbestrol (Lots II and III) ate 6 to 7 percent more total feed
than the control group (Lot I). Gains were approximately 10 percent higher for the
group receiving 10 mg. stilbestrol (Lot II) and 16 percent higher for the 20 mg.
group (Lot III). Feed cost per 100 pounds gain was slightly lower for the cattle
fed stilbestrol. There did not appear to be a difference in carcass grades,and
carcass yields were about the same for the control and two stilbestrol groups.

Dried citrus pulp and citrus meal.--These feeds were tried in rations con-
taining three parts citrus molasses, two parts ground snapped corn, and one part
either citrus pulp or citrus meal. Gains from these rations (Lots IV and V) were
somewhat lower and costs of gains were somewhat higher than for the control group
(Lot I), but it should be pointed out that the control group made an exceptionally
good gain. Carcass grades and yields were satisfactory for all groups; however,
the steers fed the citrus pulp and meal were fed 21 days longer than the controls.
In contrast to results obtained in the preceding trial,3 citrus pulp gave slightly
better results than citrus meal.

Adding corn meal to the ration.--Because of the high fiber content of
ground snapped corn rations, 4.5 pounds per head daily"of ground shelled corn was
added to the ration of Lot VI for the last 60 days of the feeding period in an
effort to improve finish. Steers in this group (Lot VI) did not gain as well prior
to adding the corn meal as the control (Lot I), and the cattle were fed 21 days
longer than the control group before slaughtering. Gains were relatively low and
costs of gain were higher for the group fed corn meal, but it should be noted that
these results are from only one trial and are possibly not representative.
Blackstrap molasses in the ration.-- Previous trials have indicated that
blackstrap molasses did not give as good results as citrus molasses when either
was fed in a ration in equal proportion with ground snapped corn.3 In an effort
to see whether a limited amount of blackstrap molasses would give satisfactory
results, 5 pounds of imported blackstrap molasses (Lot VII) and 5 pounds straight,
mill run blackstrap molasses (Lot VIII) were tried in rations with ground snapped
corn, cottonseed meal, and hay. As shown in Table 1-580, the steers fed the diluted
imported molasses (Lot VII) ate slightly more corn but gained about the same as the
steers fed the straight mill run molasses (Lot VIII). Cost of gain was slightly
higher for former ration, but differences were probably too small'to be significant.
Both kinds of blackstrap molasses produced satisfactory grades and yields. It
should be noted that the cattle fed blackstrap were fed 3 to 4 weeks longer than
the control group (Lot I).
SUMMARY

Stilbestrol fed at levels of 10 and 20 mg. per head daily in rations con-
sisting of ground snapped corn, citrus"molasses, cottonseed meal, and hay resulted
in approximately 6 and 7 percent greater feed consumption and 10 and 16 percent
higher gain than the control group not fed stilbestrol.

Substituting dried citrus pulp or citrus meal for one-third of the ground
snapped corn in a ration with equal parts corn and molasses resulted in somewhat
smaller and more expensive gains than the control group which was not fed citrus
pulp or meal.
Feeding 5 pounds of either imported or straight mill run blackstrap molasses
with ground snapped corn, cottonseed meal, and hay gave fair steer gains and ex-
cellent carcass grades and yields. Steers fed the blackstrap molasses did not gain
as'well as the control group fed equal parts ground snapped corn and citrus molasses
with cottonseed meal and hay.
