| Abstract | The modern broiler industry focuses on developing chicken breeds with high production efficiency and a short rearing period. However, these practices often come with animal welfare issues. Producers have developed slow-growing broilers to use as alternatives. However, the effects should be studied thoroughly. This study aimed to compare the performance and carcass traits of fast-growing (Cobb 500) and slow-growing (Hubbard Redbro) broilers. A total of 182 broilers were divided into 2 groups based on breed, each consisting of 7 replications of 13 birds. Production performance and carcass traits were evaluated using a t-test. The results revealed that fast-growing and slow-growing broilers reached a market weight of 2.5 kg at 33 and 40 days, respectively. The values of average daily gain of fast-growing and slow-growing broilers were 77.20 and 64.29 g/bird/day, respectively. The values of average daily gain, average daily feed intake, feed conversion ratio, and carcass traits of fast-growing broilers were better than those of slow-growing broilers. The percentage of breast meat of fast-growing broilers was greater than that of slow-growing broilers, while the percentages of thighs, legs, wings, and abdominal fat of slow-growing broilers were higher than those fast-growing. In conclusion, fast-growing broilers performed better and had a higher proportion of breast meat than slow-growing broilers, whereas slow-growing broilers had a higher proportion of appendicular skeleton cuts than fast-growing broilers. |
