Summary
Feeding immature dogs of large breeds a diet exceeding the NRC recommendations (5)
for energy, protein, calcium (Ca), phosphorus (P), and vitamin D may result in disturbances
of skeletal development. The effects of excess energy and various Ca:P ratios per
se have been reported. The role of dietary protein, especially with regard to skeletal
growth in giantbreed dogs was studied. Clinical, biochemical, radiographical, and
histological parameters were studied in three groups of Great Dane pups raised on
diets only differing in protein content (14.6, 23.1 and 31.6% dm respectively). Significant
differences were found for body weight, plasma albumin, and plasma urea. The differences
in protein intake per se had no demonstrable consequences for renal and skeletal development.
A causative role for dietary protein in disturbed enchondral ossification in dogs
is unlikely.
Nutrition is important during growth, especially in giant breed dogs. The role of
dietary protein with regard to skeletal development was studied in three groups of
