Mazama Gouazoubira ◽

Mazama Americana

O tipo de alimentação depende do ambiente em que o animal se encontra, sendo este um fator responsável pela alteração da morfologia, como a estratificação e o nível de queratinização da língua, e a funcionalidade da mesma. Dentre as estruturas morfológicas funcionais da língua, as papilas vêm merecendo destaque devido a sua estreita relação com a dieta. Foram utilizadas duas espécies de cervídeos: cinco Mazama gouazoubira e duas Mazama americana, dividindo-se a língua em três partes: ápice, corpo e raiz. Analisou comparativamente a língua de duas espécies por meio de microscopia de luz e eletrônica de varredura. As papilas filiforme, fungiforme e valada apresentaram na língua das duas espécies estudadas, e com a mesma distribuição, mudando apenas a quantidade e formato de papilas filiformes no ápice lingual e a quantidade e disposição das papilas valadas na raiz da língua, fator este que pode ser ligado à dieta dos animais. . Além disto, sua distribuição é semelhante à de outras espécies de herbívoros.

Dentre as inúmeras informações possíveis de se obter a partir da análise de artefatos ósseos, uma delas é a identificação das espécies e partes anatômicas utilizadas para a confecção desses artefatos. No território brasileiro, quatro espécies de cervídeos são comumente encontradas nas regiões sul e sudeste: Mazama americana, Mazama gouazoubira, Ozotoceros bezoarticus e Blastocerus dichotomus. Ao longo do Holoceno, ossos e galhadas dessas espécies de cervídeos foram utilizados no lascamento lítico, na produção de pontas ósseas e espátulas, entre outros artefatos. Estudos preliminares dos artefatos ósseos recuperados de três sítios arqueológicos de grupos caçadores-coletores do sudeste e sul do Brasil - sítio Lapa do Santo (MG), sítio Tunas (PR), e sítio Garivaldino (RS) - demonstram uma preferência por ossos de cervídeos para a confecção desses artefatos.

Hunting wildlife is forbidden by Brazilian federal legislation, although it is tolerated in specific situations. the activity is important as a source of protein to rural populations. the objective of this study is to describe hunting in four communities of Amanã Sustainable Development Reserve. Structured interviews were carried out with hunters themselves, as well as other members of the communities (n=238). In addition to that, a survey of hunted game was also carried out during the period of this study. In six months of monitoring of the four communities, 373 individuals were harvested; totalling 5,932.75 Kg. Mammals were the main group hunted, representing 91,42% of the total weight produced in hunting events. the results of the study indicate that the species most susceptible to hunting are Tayassu pecari, Dasyprocta fuliginosa, Cuniculus paca, Tapirus terrestres, Alouatta seniculus, Mazama americana and Mazama gouazoubira, the river turtles of genus Podocnemis, and also the Cracidae and Anatidae.

Mazama Gouazoubira

Summary In vitro production of embryos has gained prominence as a tool for use in wildlife conservation programmes in situ and ex situ. However, the development of this technique depends on steps that include ovarian stimulation, collection and oocyte maturation. The purpose of this study was to assess the feasibility of an ovarian stimulation protocol for follicular aspiration, the efficiency of videolaparoscopy for follicular aspiration and test a medium for in vitro oocyte maturation for the species Mazama gouazoubira. Five females were submitted to repeated ovarian stimulation (hormone protocol using controlled internal drug release), and estradiol benzoate on D0 and eight injections of follicle-stimulating hormone, once every 12 h, from D4 onwards at 30-day intervals. Fourteen surgical procedures were performed in superstimulated females, resulting in the collection of 94 oocytes and an average of 17.1 ± 9.1 follicles observed, 13.5 ± 6.6 follicles aspirated and 7.2 ± 3.7 oocytes collected per surgery. After collection, the oocytes were submitted to in vitro maturation for 24 h and stained with Hoechst 33342 dye to evaluate their nuclear status; 64.5% of the oocytes reached MII and 16.1% were spontaneously activated by parthenogenesis. The nuclear status of oocytes that did not undergo in vitro maturation was evaluated; 80.9% were found to be immature.

Brocket Deer

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.

Se identificaron los parásitos gastrointestinales y ectoparásitos presentes en venados cola blanca (Odocoileus virginianus), pecarí de collar (Pecari tajacu) y venado temazate (Mazama americana) en condiciones de vida libre y cautiverio en el trópico mexicano. Se obtuvieron muestras fecales y ectoparásitos de 12 ungulados de vida libre que se cazaron para fines de subsistencia y de 55 ungulados en condiciones de cautiverio. Las muestras de excremento se analizaron mediante las pruebas de Flotación Centrifugada y McMaster para conocer los géneros y órdenes de parásitos que afectan a los ungulados; así como la excreción de huevos y ooquistes por gramo de excremento. Los ectoparásitos encontrados se identificaron taxonómicamente. Las muestras positivas a nematodos del orden Strongylida y protozoos del orden Eucoccidiorida se cultivaron para su identificación taxonómica a nivel de géneros. En venados cola blanca y temazate en cautiverio se identificaron los géneros Strongyloides, Trichuris, Capillaria, Mammomonogamus y Eimeria; mientras que en los pecaríes de collar los géneros Oesophagostomun, Eimeria e Isospora. En los tres ungulados de vida libre se identificó el género Strongyloides. Sólo se encontraron ectoparásitos en ungulados de vida libre, identificándose la pulga Pulex irritans y el piojo Gliricola porcelli en venados temazate y pecaríes de collar, mientras que la mosca Lipoptena sp se colectó en los venados cola blanca. La garrapata Amblyomma cajennese se encontró parasitando a las tres especies de ungulados estudiados. Se concluye que los ungulados silvestres del presente estudio estuvieron parasitados con nematodos gastrointestinales, protozoos del orden Eucoccidiorida, pulgas,piojos, moscas y garrapatas.
