Abstract
This study evaluated the impact of a 2% phytobiotic feed supplement, incorporating nigella and milk thistle, on the performance and meat quality of Ross 308 broiler chickens under commercial conditions. The supplement replaced a portion of the standard feed. Chickens were monitored for 48 days, assessing mortality and feed conversion ratio. At slaughter, meat productivity and organoleptic characteristics were determined. The experimental group exhibited a 0.77% absolute improvement in survival rate compared to the control group. While the control group consumed more feed, the experimental group showed a 3.8% higher live weight. Carcass yield was 2.0% higher in the experimental group. Organoleptic evaluation revealed a distinct savory aftertaste attributed to the nigella in the supplement, resulting in superior sensory characteristics for both cooked meat and broth from the experimental group. The study concluded with a 9.8% absolute increase in profitability for the experimental group compared to the control.
