Abstract
Over the years, poultry supply chains have prioritized highly productive genetic lines to meet consumer demand, often at the expense of meat quality, animal welfare, and animal health. Recently, however, industry trends have shifted toward a greater awareness of welfare, reduced farming intensity, and improved product quality. In response, the European Chicken Commitment (ECC) has advocated for the use of slower-growing genotypes, even within conventional production systems. This study aimed to evaluate the meat quality of two ECC-approved chicken genotypes with differing growth rates—slow-growing (SG: 30–40 g/day, Kabir) and medium-growing (MG: 40–50 g/day, Ranger Gold) in comparison with a fast-growing strain (FG: >65 g/day, Ross 308). A total of 300 chickens were assigned to two experimental conditions: a control group (C), with spontaneous activity, and a treatment group (M), subjected to induced moderate kinetic activity. The results demonstrated that genotype influenced the meat quality of chickens raised indoors more significantly than kinetic activity. Comparisons revealed that SG and MG chickens exhibited superior meat quality, particularly regarding protein content, oxidative status, and a more suitable fatty acid profile. Overall, our findings support the adoption of ECC-approved genotypes in indoor systems to simultaneously improve animal welfare and enhance the nutritional and technological quality of poultry meat.
