Ảnh hưởng của việc bổ sung bột gấc đến năng suất và chất lượng trứng của gà Isa Brown

Abstract

The experiment was conducted on 120 Isa Brown hens aged 31–38 weeks to evaluate the effects of Gac powder supplementation in the diet. Supplementation levels included 0% (NT1), 2% (NT2), 4% (NT3), and 6% (NT4). Results showed that NT2 (2%) achieved the highest laying rate (91.69%), the largest average egg weight (67.16 g), and the best egg quality with bright yolk color (14 points). The study concludes that supplementing 2% Gac powder improves egg production efficiency and quality in Isa Brown chickens.
