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 broilersapplication/pdfQH301 Biology, SF Animal cultureArticle
