Abstract:
Sixty-four Holstein steers were used to study
the effect of season and age on performance.
Animals beginning the trial in spring were
heavier (P<.05) and more efficient than calves
started in other seasons. There were no differences
(P>.05) among seasons in average daily
gain and feed conversion after 6 mo of age. Rate
of growth was reduced after 9 mo of age for all
seasons.
