“…According to the literature, before maturity there were nearly no sex differences in total RBC count (Whittow 1999; Campbell and Ellis 2007). Similarly to our results, other authors observed no obvious hematological differences between males and females in geese and ducks (Williams and Trainer 1971; Shave and Howard 1976; Mulley 1979; Milani et al 2012). However, differences between sexes have been previously reported and can reflect a seasonal variation in hematological parameters and body condition of individuals (Whittow 1999; Campbell and Ellis 2007; Clark et al 2009; Campbell et al 2010).…”

Hematological parameters in relation to age, sex and biochemical values for mute swans (Cygnus olor)

The knowledge of the correct morphological and biochemical parameters in mute swans is an important indicator of their health status, body condition, adaptation to habitat and useful diagnostic tools in veterinary practice and ecological research. The aim of the study was to obtain hematological parameters in relation to age, sex and serum biochemistry values in wild-living mute swans. We found the significant differences in the erythrocyte count, hematocrit, hemoglobin concentration and erythrocyte sedimentation rate in relation to age of mute swans. There were no differences in hematological values between males and females. The leukogram and H/L ratio did not vary by age and sex in swans. Among of biochemical parameters the slightly increased AST, ALP, CK, K, urea, decreased CHOL and TG values were recorded. As far as we know, this is the first study in which the morphometric parameters of blood cells in mute swans were presented. We found extremely low concentration of lead in blood (at subtreshold level). No blood parasites were found in blood smears. The analysis of body mass and biometric parameters revealed a significant differences dependent on age and sex. No differences in the scaled mass index were found. Our results represent a normal hematologic and blood chemistry values and age-sex related changes, as reference values for the mute swan.

“…The hematological values may be affected by time of day, moulting period, nutrition status, environmental conditions and applied treatment (e.g. steroids) (Shave and Howard 1976; Driver 1981; Whittow 1999; Artacho et al 2007a; Artacho et al 2007b; Katavolos et al 2007; Calabuig et al 2010; Milani et al 2012). …”

HAEMATOLOGY OF THE WOOD DUCK, Chenonetta jubata

Mulley

Journal of Wildlife Diseases

Haematologic values have been determined for the wood duck, Chenonetta jubata, captured in the western fringes of Sydney. Values for females were usually slightly higher, and this follows the pattern for other species sampled in the prenesting period. The differences in haematological values between males and females were not statistically significant. INTRODUCTIONThe wood duck (Chenonetta jubata) is a nomadic duck favouring lightly timbered country near water. 3 Haematologic values for many of the anatids, including this species, have not been reported. This paper presents haematologic values for the wood duck, a member of the tribe Cairinini.

“…fluence of age, sex, physical and environmental conditions, and circadian rhythm on hematological values(Erlenbach 1938, Defalco 1942, Cooper 1972, Halliwell et al 1975). Others account for only 1 or 2 of these variables (Williams and Trainer 1971,Milsom et al 1973, Conetta et al 1974, Shave and Howard 1976). Our report is unique because we examined species about which little is known, and we compared hematological values after standardizing collecting, processing, and analyzing procedures.…”
