The Need of Balanced Ration. In such circumstance the addition of a concentrate
becomes a necessity in order that the experiment can be conducted under more
normal conditions where the animals could have at least a balanced ration. But
with a mixed ration (here one roughage and one concentrate) the necessity arises
to assume that the digestibility of one of the feeds is known and constant, so that
by corresponding elemination we may calculate the digestibility of the other. Since
however such digestibility figures for India are not available, we had to rely on
" known " published data of elsewhere (European or American) and thereby, making
the corresponding deduction, assign the digestibilities of the roughage.
EXPERIMENTAL SCHEME.
Our investigation naturally included this part of the trial (viz., calculation by
assumed values) and in order to combine in the same the other objectives now
