A total of 72 commercial broilers were scanned at 6, 7, 8, 10, 16 and 20 weeks of age using magnetic resonance imaging (MRI) tomography.MRI scans based on spin echo sequence were taken in the 3 orthogonal planes.Between 6 and 20 weeks of age, the volume of the pectoral muscles increased from 259 to 1035 cm3 in males and from 250 to 875 cm3 in females, and total body fat volume increased from 129 to 557 cm3 in males and from 171 to 1321 cm3 in females.Abdominal fat volume increased from 18.9 to 153.2 cm3 in males and from 19.3 to 267.0 cm3 in females between 7 and 20 weeks of age.The correlation coefficiens between the total volume of fat pixels and the amount of abdominal fat determined in the coronal plane by MRI were 0.85 and 0.95 in males and females, respectively.
