Effect of sex and seasons of the year on hematologic and serum biochemical variables of captive brown brocket deer (Mazama gouazoubira)

Abstract

Pesq. Vet. Bras. 33(11):1364-1370 The Brown brocket deer (Mazama gouazoubira) is the most common free-living and captive deer in South America, especially in Brazil, and has great ecological and scientific significance. However, data on hematological and biochemical parameters in brown brocket deer are scarce. The goal of this study was to establish reference ranges for hematological and biochemical parameters of Mazama gouazoubira, comparing differences during the seasons of the year and between sex. Blood samples from ten adult healthy brown brocket deer (6 female and 4 male) were collected during daytime, monthly, during 12 months. The animals were maintained in individual stable, protected from noise and fed ad libitum with commercial ration and green fodder. For blood collection, animals were submitted to physical restrain for no longer than 2 minutes. The following parameters were determined: red blood cell count (RBC), haemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count (WBC), platelet count, enzyme activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and serum levels of alkaline phosphatase (ALP), creatine kinase (CK), total protein (TP), albumin, cholesterol, total calcium, ionic calcium, sodium, potassium, magnesium, triglycerides, creatinine and urea. Values were compared according to season and sex. RBC count, WBC count and MCV suggested seasonal influence. Haemoglobin concentration, PCV and MCV were influenced by sex. Serum concentration of total calcium, ionic calcium, sodium, potassium and magnesium were influenced by season. Serum magnesium was also influenced by sex. The blood parameters herein reported may be useful as reference values for diagnostic and prognostic purposes in captive brown--brocket deer.INDEX TERMS: Brown brocket deer, hematology, Mazama gouazoubira, seasonality, serum biochemistry.

Physiological, Biochemical, and Growth Parameters of Fogera Cattle Calves to Heat Stress during Different Seasons in Sub-Humid Part of Ethiopia

“…According to Celik et al [ 32 ], HGB and MCH levels were not statistically different between the sex of the calves, which is concordant with our findings. Moreover, Camargo et al [ 33 ] also did not find a significant difference between males and females in MCHC, which is also in line with our result.…”

Semen collection in Rusa timorensis under general anaesthesia by using ketamine-xylazine: Clinical study

“…The deer were herded from the paddock into the dark house as the deer are calmer in the dark house, which allowing for physical restraint in small-sized area (15). The head of the deer was controlled by farmer, while other person held the deer shoulder while exerting downward pressure to prevent the deer from jumping (16). General anaesthesia was conducted using a combination of Ketamine and Xylazine at the dosage of 2mg/kg and, 1mg/kg respectively (17).…”

Conhecimento ecológico local sobre o veado, Mazama Gouazoubira (g. Fischer, 1814), por moradores do entorno de uma área protegida do semiárido brasileiro

“…A concentração de estudos sobre M. gouazoubira tem sido na área de uso e seleção de habitat (BLACK-DÉCI-MA, 2000;CARABALLO, 2009;RIVERO;RUMIZ;TABER., 2005;ROMERO & CHATELLENAZ, 2013), além de trabalhos sobre comportamento alimentar (RICHARD & RADA, 2006;SERBENT;LEYNAUD, 2011), taxonomia morfológica (ANGELI; OLIVEIRA; DUARTE, 2014; GARDNER, 1999), ecologia comportamental (BLACK-DÉCIMA & SANTANA, 2011), reprodução (ZA-NETTI et al, 2014) e genética/bioquímica (CAMARGO et al, 2013). Sob o enfoque da etnozoologia, pesquisas especificamente com M. gouazoubira ainda são incipientes; os dados disponíveis na literatura referem-se a trabalhos genéricos no contexto do conhecimento local das espécies brasileiras de cervídeos do gênero Mazama (Rafinesque, 1817) (GEHARA et al, 2009;VOGLIOTTI, 2003).…”
