Nutrition, weight gain and development of hip dysplasia. An experimental investigation in growing dogs with special reference to the effect of feeding intensity.


Thirty-one dogs from 5 litters with a high parental frequency of hip dysplasia were used in the investigation. Each litter was split in two groups, of which one was put on a high caloric intake, the other one on a low caloric intake. Each member of a group had a paired litter mate in the other group. The litter mates were paired on the basis of the result of a palpatory examination of the hip joints before 12 weeks of age. If possible, paired mates were of the same bodyweight at the time of palpation, and of the same sex. In the groups made up of pups from 3 of the litters, the protein intake was kept at an optimal level, regardless of the amount of calories given. It was found that hip dysplasia was more frequent, occurred earlier, and became more severe in the dogs with a rapid weight gain caused by increased caloric intake than in the dogs which had a low weight gain because of restricted feeding. The final diagnosis was closer correlated with feeding and weight gain than with tightness or laxity of the hip joints before 12 weeks of age.
