Valores hematológicos de bugios pretos (Alouatta caraya) de vida livre da região do Alto Rio Paraná, sul do Brasil

Abstract

Valores hematológicos de bugios pretos (Alouatta caraya) de vida livre da região do AltoRio Paraná, sul do Brasil [Hematologic values of free-ranging black-and-gold 46±3.53 and 36.69±3.54%) and plasma total protein (7.91±0.53 and 7.40±0.63g/dL) were lower in juveniles.

Hematological parameters and the variations resulting from stress of Alouatta caraya during a wildlife rescue program in Brazil

“…In general, the parameters evaluated here are comparable to those reported for this species in captivity in Brazil [Santos, ] and when compared to data obtained from free‐ranging specimens by Flaiban et al [], except in leukocyte counts. Both genders exhibited leukocytosis and neutrophilia, with specimens exhibiting higher values at capture in both genders and at captivity in females (see Table .).…”

“…Nonetheless, results presented in those studies should be more specific to the primates they evaluated; it is necessary to consider many other factors, such as nutritional condition, physiological variations, age group, stress, and conditions of captivity [Almosny, ]. The sex variation for several of the parameters, as observed in this study, has previously been reported for other primate species [Flaiban et al, ; Kagira et al, ; Larsson et al, ; Moore, ; Santos, ; Takeshita et al, ; Thrall, ; Wirz et al, ] and is mainly due to hormonal influence because testosterone stimulates erythropoiesis, whereas estrogen inhibits erythropoiesis [Kagira et al, ; Wirz et al, ].…”

“…Results obtained from this study are particularly valuable because little data are available regarding the hematological parameters of New World primate species [Riviello & Wirz, ], especially under stressful conditions. Thus, subsequent studies with similar capture characteristics can use these results, assuming that hematologic values obtained from anesthetized animals may be considered standards because they cannot be obtained without the use of drugs [Flaiban et al, ]. By using ketamine, a portion of the hematological values is comparable within 10 minutes [Loomis et al, ], and there is no change in erythrocytic counts up to 40 minutes [Porter, ].…”

Hematology and blood biochemistry in wild hybrid marmosets from the Atlantic Forest, Brazil

“…The hematological and blood biochemical values of free-ranging animals can help in the diagnosis of some diseases, especially when other factors are taken into account that may infl uence these values like gender, age, stress, or anesthetic agents (FLAIBAN et al, 2008).…”

Effectivness of the GnRH analogue deslorelin as a reversible contraceptive in a neotropical primate, the Common Marmoset Callithrix Jacchus (Mammalia: Primates: Callitrichidae)

“…The three females of group D were anesthetized with a combination of Tiletamine and Zolazepam (Zoletil® Virbac Brazil) at a dose of 5.5 mg/kg intramuscularly (Flaiban et al 2009). Once tranquilized, all three females received a subcutaneous implant, containing 2.35mg of deslorelin acetate (Suprelorin® Peptech Animal Health, Australia).…”
