Abstract excerpt

In response to the growing demand for alternative poultry systems, such as free-range or organic farming, slow-growing chicken lines are preferred for their robustness and meat quality. However, genetic selection is usually conducted under indoor conditions, which may not reflect outdoor challenges and may decrease the effectiveness of selection if genotype × environment (G × E) interactions exist.
