Comparing slow-growing chickens produced by two- and three-way crossings with commercial genotypes. 1. Growth and carcass traits

This study compared growth and carcass traits of slow-and medium-growing chickens produced by two-and three-way crossings with those of commercial fast-and slow-growing chickens at 8, 10 and 12 weeks of age. In total, 2,240 mixed male and female day-old chicks from each of six different genotypes [ two-way crossings (S1 and S2), three-way crossings (S3, S4, S5 and S6), commercial fast-growing (F), commercial slow-growing (CS)] were randomly allocated among four compartments of the same house.
