Bagasse is the fibrous residue remaining after the sugarcane
stalk has been crushed and the juice pressed out. During 1970-71

over 700,000 tons of bagasse will probably be produced in South

Florida. Bagasse contains approximately 355 fiber. This material

has been shown to be a good source of roughage in beef cattle

rations2, but its bulky nature has limited its commercial use for

this purpose.

The purpose of this study was to compare pelleted bagasse to
cottonseed hulls as a source of roughage in completectle--


Experimental Procedure JUL 1. 1972

Forty-eight two-year-old crossbred Brahman l.1tihoiSnk. of Florida
Charolais steers were divided into four equal groups of 12
animals each, on the basis of weight and grade, and the groups
randomly allotted to the experimental feed mixtures presented in

Table 1. The bagasse material was obtained by passing whole bagasse
through a series of rotary screens to remove the larger, harder

pieces of sugarcane barrel. The portion falling through the screens
was sugarcane pith plus the smaller pieces of the stalk barrel.

./Bagasse pellets were furnished by United States Sugar Corporation,
Clewiston, Florida.

This material was treated with steam at the pellet mill to soften

the fibers, mixed with six to seven percent of cane molasses

and made into a 3/8 inch pellet. The pellet contained 3.5% crude

protein, 37% crude fiber and weighed about 42 pounds per cubic foot.

vitamin A per lb.

Complete fattening rations (Table 1) were used, containing
either cottonseed hulls or bagasse pellets as the roughage material.
The feeds were full-fed, once per day, for 91 days. Before the
beginning of the experiment the steers had been receiving pangola-
grass hay as their roughage and the hay was gradually replaced with
the cottonseed hulls or bagasse pellets.

The cattle were shrunk 14 hours before the initial and final
weights were taken, to minimize the effect of fill on live weights.

At the conclusion of the 91-day feeding period the cattle were

shipped to Lykes Brothers Packing Co., Plant City, for carcass

evaluation. /

Experimental Results

Average gain and carcass data for the experimental cattle are

presented in Table 2. The cattle receiving the lower level of

cottonseed hulls or bagasse pellets had an average daily gain per

steer of 2.97 and 2.85, respectively. The amount of feed eaten per

pound of gain was approximately the same for the two groups of

steers. The cattle receiving 7.5% bagasse had a slightly lower

carcass grade, slightly less kidney fat, fat over the rib-eye and

marbling, and had a higher dressing percent and estimated percent

yield, than the cattle receiving the 7.5% cottonseed hull ration.

The cattle receiving 7.5% bagasse were easier to keep on feed than

those eating the 7.55/ cottonseed hulls. There were no apparent

harmful effects of bagasse on the rumen, although the rumen contents

were darker for the steers eating the bagasse rations as compared

to those eating cottonseed hulls.

Cattle receiving the rations containing the 15fa level of cotton-

seed hulls or bagasse had a lower average daily gain and a lower feed

efficiency than those receiving the 7.5i/ levels of the two feeds. The

steers receiving the higher level of bagasse out performed the cattle

receiving the higher level of cottonseed hulls. Fifteen percent of

either material woa too high for optimum steer performance on

fattening rations. The 7.55 level was satisfactory, but experience

was needed to keep cattle on feed. It may be necessary to

provide a temporary supply of additional roughage to keep the cattle

from going off feed on lower levels of these roughages, but both

materials were satisfactory sources of roughage in these fattening
