OBSERVATIONS ON THE PALATABILITY OF A BLACKSTRAP
MOLASSES MIXTURE, ADJUSTED TO pH of 8.0
H. L. CHAPMAN, JR. and C. L. DANTZMAN- -
Some additives are not stable when added to a liquid supplement due to low
pH. Liquid supplements may have a pH as low as 3.0, depending upon the ingredients
included in the mixture. If th pH of molasses, or molasses-mixtures, can be
adjusted to 8.0, the stability of some additives may be increased. The purpose
of this study was to determine the palatability of a molasses mixture that was
adjusted from an initial pH of 5.0 to a pH of 8.0.
A molasses-mixture containing heavy millrun blackstrap molasses, 3.0% urea,
2% feed-grade phosphoric acid, copper sulfate, cobalt sulfate, zinc sulfate and
vitamins A, D3 and E was used in the experiment. The initial .atch of molasses
had a pH of 5.0. The pH was adjusted by adding sufficient amounts of a 49%
solution of calcium chloride and -0% sodium hydroxide solution to bring the pH up
to 8.0. The initial batch of molasses required approximately 25 pounds of the
calcium chloride solution and 13 pounds of the sodium hydroxide solution to
reach the desired conditions for stabilization. Subsequent mixtures fluctuated
slightly in the amount of solutions needed to adjust the pH to 8.0, depending
upon the initial pH of the molasses mixture.
The molasses mixtures were fed to cattle to determine the palatability of
the mixture with the adjusted pH. Both the regular molasses mixture and the
molasses mixture with the adjusted pH were offered, free choice, to a group of
yearling bulls and a group of yearling heifers, of Santa Gertrudis, harbray
and Brahman breeding, for 31 days. After this period of time, the group of
bulls was fed the molasses with the adjusted pH and the heifers were fed the
unadjusted molasses, for another 38 days. The bulls grazed Argentina bahiagrass'
and the heifers a pasture containing a mixture of Pangola, bermuda and vasey
grass. In addition the cattle received 5.0 lbs. per animal per day of a dry,
high-energy supplement, plus free-chui.-e pangola hay. The .,nly experimental,
data collected was molasses consumption.

Molasses intake during both feeding periods was fairly low. This was
probably due to the fact that the dry supplement was also being fed. The
bulls ate more molasses than the heifers, during both feeding periods (Table 1.)

During the first feeding period the bulls ate the same amount of each molasses
and the heifers ate about 14% more of the molasses with the 5.0 pH. During
the second feeding period the bulls ate 2.12 pounds a day per head of the
8.0 pH molasses and athe heifers ate 1.82 pounds per head per day of the 5.0
