In order to evaluate the effect of hybrid on nutrient composition and organoleptic
characteristics of broiler thigh meat; broiler hybrids namely, Arbor acre, Cobb 500
and Ross 308 commercial broilers were assessed. These hybrids constituted the
treatment. Each hybrid was replicated 3 times, while each replicate contained 51
birds, making a total of 459 birds. The Completely Randomized Design was
adopted. GLM-ANOVA and Tukey’s HSD (α =0.05) procedures were used for
nutrient analysis. The Kruskal-Wallis H, followed by Dunn’s mean separation,
α=0.05, were used for analysis of sensory scores. The Principal Factor Analytical
procedure (score-1) was used to expose the root contributions of hybrids to
nutrient profile and sensory attributes. Cobb 500 thigh meat was higher in crude
protein, fat, calories, sodium and potassium than Arbor acre and Ross 308 hybrids
(P < 0.05); but hybrids showed similar average root contributions to nutrient
content (PF-1 = -0.142 to 0.154) of the raw thigh. Cooked Ross 308 thigh meat
revealed higher colour, aroma and average score (PFS-1 = 0.74-0.83) over Arbor
acre and Cobb 500 hybrids; but hybrids were similar in all sensory characteristics
except smoothness (K-W X2 = 9.39; P <0.009), where Arbor acre had lower mean
rank of 130 against other two hybrids with minimum of 156. Cobb 500 was better
in nutrient content, while Arbor acre hybrid was higher in thigh smoothness, and
these could be selected explicitly for improvement.
