Implication

Randomized trial reveals genetic strain and sex alter carcass yields and meat traits in broilers, indicating high-yield breeding does not compromise consumer acceptability.

Key Points

To evaluate the impact of broiler genetic strain and sex on carcass yield, meat quality parameters, and consumer sensory acceptability.
Evaluated commercial broilers (Strain A) and a high breast-yield test strain (Strain B) across both sexes using a randomized complete block factorial design.
Harvested 42-day-old broilers at a pilot processing facility, deboned carcasses at 4 hours postmortem, and analyzed breast halves for pH, color, cooking loss, shear force, proximate composition, and consumer sensory ratings.
Broilers from Strain B produced significantly higher dressing percentages and breast yields than Strain A (P < 0.05).
Male broilers exhibited greater live body weight, carcass weight, and breast weight but lower dressing percentage and breast yield compared to females (P < 0.05).
No differences existed between strains or sexes for pH decline, cooking loss, shear force, proximate composition, or consumer scores for appearance, texture, flavor, and overall acceptability (P > 0.05), though Strain B showed superior aroma preference (P < 0.05).
