Production performance of livestock is mostly dependent on the breed, nutrition and management practices (stocking density). The experiment was carried out to evaluate the effect of population density on morphometric traits of Agrited and Amo broiler chickens. Performance traits considered were initial body weight, final body weight, body weight gain, average daily weight gain, average feed intake, average weekly feed intake and feed conversion ratio (FCR). Morphometric traits include thigh length, shank length, neck length, heart girth, body length, wing length and thigh circumference. While the cost-benefit analysis carried out include cost of feed/kg diet, cost per kg weight gain, total cost of feed per birth and cost of production per birth. Data generated were analyzed using ANOVA. Body weight gain was not significant (P>0.05). Agrited had high values for the average daily weight gain (42.91g), average total feed intake (5380.90g) and average weekly feed intake (768.70g). The body weight, shank length, and neck length were not affected (P>0.05) by stocking density in both strains. The cost per kg weight gain (? 726.35), total cost of feed per birth (? 1765.03) and cost of production per birth (? 2126.30) were less and best estimated in Amo strain. Hence, the two strains were not affected by stocking density in most traits measured.
