Plasma chemistry in peregrine falcons (Falco peregrinus): Reference values and physiological variations of importance for interpretation

Abstract

Reference values for the calculated albumin/globulin (A/G) ratio were 0.8 to 24. Based on previous studies, reference values for calcium were established using an adjustment formula using plasma total protein concentrations (before correction 1.86 to 2.49, after correction 1.97 to 2.46 mmol/l). Results of plasma potassium concentrations were erratic which was shown to be due to a time lag between sample collection and separation of plasma and cells.

Hematological, Protein Electrophoresis and Cholinesterase Values of Free-Living Nestling Peregrine Falcons in Spain

“…The range for total protein is in accordance with those obtained for adult peregrine falcons (Lumeij et al, 1998) and other birds of prey such as captive and free living condors (Vultur gryphus) (Toro et al, 1997) and Mauritius kestrel (Falco punctatus) (Cooper et al, 1986).…”

“…Direct measurement of OP and carbamate insecticide residues from operational applications is difficult and often impractical because these insecticides are quite labile in biological tissues and a large number of compounds are in use. The results obtained in this work are higher than those described in adult birds by Lumeij et al, (1998), although the methodology used was similar. This enzyme is absent in avians (Farage-Elawar et al, 1988).…”

“…Previously, Lumeij et al (1998) indicated that these kinds of data are not fitted to a normal distribution. Previously, Lumeij et al (1998) indicated that these kinds of data are not fitted to a normal distribution.…”

“…Protein electrophoresis was developed using cellulose acetate (Lumeij, 1987). Total protein (TP) was determined with the Biuret method (Lumeij and MacLean, 1996).…”

“…Reference values for different plasma chemical variables in adult falcons have been recently established (Redig, 1993;Cray and Tatum, 1998;Lumeij et al, 1998). However, there is very little information available on chemistry and hematological values for free-living nestling peregrine falcons.…”
