Femur Mineral Density of Broilers with Femoral Degeneration Fed High Nutritional Density Diets International Journal of Morphology
Al meida Paz,I. C. L; Mendes,A. A; Martins,M. R. F. B; Fernandes,B. C. S; Almeida,I. C. L; Milbradt,E. L; Balog,A; Komiyama,C. M.
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 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. Birds were then sacrificed for gross examination of the legs, and FD scoring. Five...

Follow-up of the Development of Femoral Degeneration Lesions in Broilers International Journal of Morphology
Almeida Paz,I. C. L; Mendes,A. A; Martins,M. R. F. B; Fernandes,B. C. S; Almeida,I. C. L; Milbradt,E. L; Balog,A; Komiyama,C. M.
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. Histological analyses of femur head collected when broilers were 0, 7, 14, 21, 28, 35, and 42 days of age were carried out. At 42 days of age, 30 birds were taken to the experimental processing plant of FMVZ for leg gross examination. Ten legs per FD score where selected, and histologically analyzed to determine the most probable age at the beginning of the lesions, and to standardize femoral degeneration lesion scores. The histological results showed that cell architecture started to disorganize at 21 days of...
