The NORM birds had greater (P< 0.05) abdominal fat yields than SEV birds, but there
was no difference in the weight of the abdominal fat pad between the 2 groups.A negative genetic correlation has been reported between abdominal fat and BW (Leenstra et al., 1986) or breast meat yield (Cahaner et al., 1986; Le Bihan-Duval et al., 1998; Zerehdaran et al., 2004).This could be why the SEV birds, which had greater (P < 0.05) live weights and fillet yields, had a lower (P < 0.05) abdominal fat yield (Table 1)
