PRELIMINARY RESULTS WITH BEEF CATTLE ON DIGESTIBILITY
OF NUTRIENTS IN PELLETED AND LONG COASTAL BERMUDAGRASS HAY*

(A summary of research results to date on projects in progress)

Coastal Bermudagrass, properly fertilized and managed, can be an
economical source of high protein forage for fattening cattle; however,
the storage and self-feeding of this grass presents a manpower problem.
Pelleting of grasses has shown promise of reducing these manpower require-
ments; therefore, information on how pelleting affects the nutritive value
of feeds is needed.

This experiment was conducted to answer the question, "Are the
nutrients in pelleted Coastal Bermudagrass hay as digestible as those in
long Coastal Bermudagrass hay?"

EXPERIMENTAL PROCEDURE

The hay in this experiment was from a second cutting of Coastal
Bermudagrass at the Suwannee Valley Experiment Station, Live Oak, Florida.
An application of 500 pounds 0-10-20 and 600 pounds ammonium nitrate was
applied on July 15, 1958, and the grass was cut for hay five weeks later.

One half of the hay from this cutting was ground through a 1/4" screen
in a hammermill and was made into 3/8 inch pellets. The remainder of the
hay was stored under cover until fed. Four mature, open Hereford cows
were used to determine the digestibility of nutrients in these hays. These
cows were limited in feed intake to an amount sufficient for maintenance
of weight. The results of this experiment are shown in the following table:









*The cooperation of the Florida Feed Mills, Jacksonville, Florida in
pettleting the Coastal Bermudagrass hay is acknowledged.

DISCUSSION CF RESULTS

1. The total protein content of this Coastal Bermudagrass hay is high
for grasses in Florida and approaches that found in high quality
legume forages.

2. The protein content of this hay from heavily fertilized grass was
highly digestible for cows fed only the grass and a mineral mixture.

3. The digestibility of protein apparently was not affected by pelleting.

4. Gross energy and digestibility of gross energy were both lower in the
pelleted than in the long hay. This observation is under further
investigation.
