Femur Mineral Density of Broilers with Femoral Degeneration Fed High Nutritional Density Diets
A study was carried out in the experimental facilities of FMVZ/UNESP-Botucatu, with the aim of following-up the development and the incidence of femoral degeneration (FD). A total of 305 one-day-old male broilers were housed in six pens of 5m² each. A completely randomized experimental design, with...

A total of 305 one-day-old male broilers were housed in six pens of 5m² each. A completely randomized experimental design, with 3 treatments (T1traditional nutritional density diet; T2high nutritional density diet) of 3 replicates each was applied. Femoral head of the broilers were submitted to gross examination at 0, 7, 14, 21, 28, 35, and 42 days of aged. At 42 days of age, 60 birds (30 per treatment) were submitted to the Veterinary Hospital of FMVZ to determine bone mineral density by radiography.

Five legs per treatment within each FD score were submitted to computed tomography for femur head integrity and bone mineral density.
