to 92-98% of the National Research Council recommenda-
tion will provide the same or increased live weight gain
and increased feed effi ciency as 100% of the dietary rec-
ommendation. There also appears to be decreased heat
production with 92-98% feeding compared with less than
90% or 100% feeding of the recommended amounts
(Galyean, 1999 ).

Some trace minerals may enhance growth. Addition of
100 mg copper daily increased ADG in Boer

goats without causing copper toxicity, presumably by
enhancing the immune responses (Solaiman et al., 2007).
There have been few studies on the effects of growth-
promoting agents, but goats would appear to be similarly
infl uenced as the other ruminant livestock species, sheep
