of all losses during the passage of the feed through
the alimentary canal, but these limitations can
be lessened in practice by bearing in mind that
digestibility is influenced by many factors and also
by taking into account the losses to which digested
nutrients are subject during the metabolic cycle.
We have accordingly shown the total digestible
nutrients in Table IV for all the feeds investigated.
In conclusion it may be pointed out that the
data now presented represent fundamental data,
the value of which can only be properly utilized
if applied in the computing of rations on the basis
of digestible nutrients which the various rations
contain and of economic factors connected with
the prices of feeding stuffs at various times of the
year.
