2008). Regarding protein digestibility, Dawson
et al. (1988) reported that pre-ruminant calves
digest proteins from milk sources more efficiently
than soy proteins. In our study, milkreplacers
were mainly based on dairy proteins
(Table 1) and consistent with the previous
assumption, a higher CP digestibility was
observed in calves fed the entire dose of milkreplacer
(CG and CGS) compared to those for
which milk-replacer was restricted and partially
replaced by a vegetable protein source
(CGSES). Therefore, since protein is the first
factor limiting calves growth during the early
stage of fattening (Roy et al., 1971), in order to
avoid the waste of dietary protein, digestibility
of vegetable sources should be carefully estimated
when formulating feeding plans for veal
calves in which a dairy-based milk-replacer is
partially substituted by solid feeds in the first
part of the fattening cycle.
