#1 Rather standard levels of infection on broiler farms (Peek et al., 2017). #2 For Farm 2, the condemnation rates were slightly above (Farm 2) and below average (Farm 1) compared with average rates for European broiler farms and the reasons for condemnation did not indicate specific abnormalities related to poor health (Löhren, 2012; Salines, Allain, Roul, Magras, & Le Bouquin, 2017) (D = day).
