Table IV.

The results of blood counts and reproduction results from commercially bred blue color type mink (n = 289) from 5 Danish mink farms were compared to the presence of periodontal disease and tooth loss. Blood morphology was assessed visually by differential counts of a minimum of 200 blood leucocytes and percentages of C-HS leukocytes (defined as neutrophilic leukocyte containing 1 or more abnormally large lysosomes) were recorded. Through the use of radiographs, periodontal disease was assessed in 1 randomly chosen half of the mandible from each mink, by determining the alveolar bone loss and tooth loss of 4 selected teeth (premolar 3 [P3] and 4 [P4] and molar 1 [M1] and 2 [M2]). The animals were recorded as affected by periodontal disease and or tooth loss or not affected. Reproduction results were obtained from farm records and presented as the average number of pups at weaning. The P-values indicate significant differences in leucocytecounts between the groups compared
