Background:
As large breed, highly muscled dogs, greyhounds are regarded as physiologically different to other breeds. Biochemistry reference intervals have previously been determined using small numbers of greyhounds or based on the observations from racing dogs.
Objectives:
The purpose of this study was to develop statistically defined reference intervals for biochemical analytes in healthy non-racing greyhounds. Partitioning according to gender was also examined.
Methods:
Biochemical analytes from a population of non-racing healthy greyhounds, including 269 males, 202 females and 28 dogs where gender had not been recorded, were examined using a non-parametric statistical approach. The dogs were aged between one and nine years old.
Results:
Total protein, albumin, globulin and creatinine reference intervals differed from generic reference intervals used for dogs. The reference intervals for greyhounds in this study are similar to those obtained by other studies of greyhounds, but often had a narrower range of values, likely reflecting more accurate estimation associated with larger numbers of reference individuals. Recommended methods for assessment of partitioning do not indicate a need to partition according to gender.
