Abstract
Description
A total of four hundred and eighty day-old commercial
b+oiler chicks were assigned t? 12 dietary treatments in a 2
x 6 factorial experiment to study the effects of biotin and
palm kernel oil supplementation on their performance and
carcass characteristics. Measurements of average daily
weight gain, average daily feed intake, carcass weight,'
dressing percentage, total edible meat weight and total bone
weight showed that a minimum of 120 mcg biotin per kg of feed
was needed by broiler chicks for optimum perfor~ance. All
carcass characteristics examined except total bone expressed
as percentage of carcass weight were positively correlated
with di.et~ry biotin level, although none was significant ,
(P>0.'05). Supplementation of diet with 2% palm kernel oil
significan.tly (P < 0.05) reduced average daily feed intake and '
average weight gain but did not affect feed efficiency
(gairi/feedintake) and carcaSB characteristics of broilers
