Table 2.

Glomerular filtration rate measurements (GFR (mL/min/kg), mean ± SD) using creatinine and exo-iohexol in six different avian species (♂/♀). The GFR is indexed to bodyweight.

Species	Creatinine	Exo-iohexol
Broiler chicken	8.41 ± 1.63^a	3.09 ± 0.65^c
Laying chicken	9.33 ± 0.73^a	2.57 ± 0.23^cd
Turkey	5.62 ± 0.81^a	1.94 ± 0.39^d
Pigeon	14.97 ± 1.78^ab	1.29 ± 0.47^ef
Duck	17.59 ± 12.20^ab	2.60 ± 0.38^c
Parrot	25.56 ± 15.21^b	1.11 ± 0.34^f

Results with a different alphabetical character superscript are considered significantly different (p < 0.05) between the different bird species within one technique. For each bird species, the mean renal clearance of creatinine differt significantly with the mean renal clearence of iohexol.
