Abstract

Clinically healthy silver foxes obtained from a closed colony were investigated for the purpose of establishing base-line data for this species. The anthropometry (body weight ; body length ; length and width of the head ; width, depth, and circumference of the chest ; length of the tail), anatomical measurements (weight ; longitudinal and transverse length ; thickness of the main organs) and serum biochemical assays (AST, ALT, ALP, LDH, CK, lipase, GGT, T-Cho, β-Lipo, TG, Phos-Lip, Tp, T-Bil, UA, BUN, Crea, Glu, Ca, IP, Mg, Fe, Na, K, Cl, LDH and CK isoenzymes) were carried out. The data were presented as mean values with standard deviations, and compared with those of the dog. The coefficient of variation (CV) for each of the anthropometric parameters was low, except for that of female body weight for which the CV was 17%. The body size of the male was larger than the female, and the weights of the main organs, corresponding to body size, were greater than the female. The results were equivalent to those for a Beagle dog aged between 3 and 5 months. Significant differences between the sexes were detected in the following parameters : concentrations of BUN, β-Lipo and T-Bil (p<0.01) ; concentration of Mg and Glu (p<0.05) ; activity of LDH and lipase (p<0.05). The biochemical data ware uniform with some exceptions. These were AST (142 NU/l) and ALP (122 IU/l) in a 5-year-old male fox, Glu (over 200 mg/dl) in four 2-year-old female foxes, CK (629 IU/l) in a 2-year-old female fox, and finally CK (366 NU/l) and lipase (428 IU/l) in an 8-year-old female fox, all of which were elevated. These data were similar to the reference values for the dog previously reported. The reference values presented in this report for the silver fox will be valuable as a guide for clinical diagnosis and research.
