Fig 4. Associations of space allowance (m²/bird) with (A) rejections due to wounds (r² = 0.151), (B) growth rate (r² = 0.007), and (C) production index (r² = 0.048).

Data points are back-transformed estimates from analysis of residuals of space allowance regressed on environmental complexity. (A) Carcasses rejected due to wounds as a % of total slaughtered birds. (B) [Mean g eviscerated carcass weight/days of age at slaughter]. (C) [Mean g eviscerated carcass weight * (number slaughtered − number rejected)/(days of age at slaughter * number of chicks started)].
