Abstract The objective of this study was to investigate the effect of inorganic
and organic components of molasses on the laxative problem
encountered when molasses makes up a large portion of livestock
rations. In a series of four trials 280 male Long Evans rats weighing
approximately 50 grams each were placed on dietary treatments,
each supplying or removing a possible causative agent.
In the first trial the involvement of inorganic components and in
particular potassium was studied in their relation to the laxative
effect. Potassium when supplied at a level calculated to be equivalent
to the content of molasses did not cause any laxative effect.
However, it did result in increased water consumption by rats.
The addition of molasses ash to the diet did not cause any laxative
effect in the rats but did cause increased water consumption as did the potassium.
The second trial was designed to scan other factors which might
be involved in the laxative problem. Magnesium when supplied as
MgSO₄ at a level calculated to be equivalent to the magnesium concentration
of the molasses-supplemented diet did cause loose droppings
in all rats receiving that diet.
The results of the third trial were quite variable, mainly due to
poor experimental technique and were not considered in the final
conclusions. The trial pointed out several areas where experimental
technique could be refined.
The fourth trial showed that magnesium when supplied as dicalcium
magnesium aconitate at a level calculated to be equivalent
to its concentration in the molasses-supplemented diet produced dry
matter values of the large intestinal content similar to the rats on
the molasses-supplemented diet. However, the wet weight of large
intestinal contents of rats receiving the dicalcium magnesium
aconitate diets was significantly (P < 0.01) less than that of the rats
on the molasses containing diet, but significantly (P < 0.05) more
than that of the rats on the basal diet. The addition of potassium to
the dicalcium magnesium aconitate diet did not affect the dry matter
or wet weight of the large intestinal contents of the rats. It did, as
before, cause an increased water consumption by the rats on the
high potassium diets. Rats on the deionized molasses and cation-free molasses showed significantly (P < 0.05) higher dry
matter values for the contents of the large intestine over the dry
matter values recorded on the rats on the molasses diet, but still
below the value recorded for the rats on the basal diet. The rats on
the anion-free molasses showed no differences in dry matter of
large intestinal contents from those rats on the molasses containing
diet. Wet weight of large intestinal contents of the rats was significantly
(P < 0.01) reduced by the cation-free molasses and deionized
molasses. The wet weight of the contents of the large intestine of
the rats on the dicalcium magnesium aconitate diet was significantly
(P < 0.05) increased over that of the rats on the basal diet but was
significantly (P < 0.01) less than that of the rats on the molasses-supplemented diet.
