Valores de referência de uréia e creatinina para javali (sus scrofa scrofa, linnaeus, 1758) em cativeiro

In Brazil, the commercial breeding of wild boars (Sus scrofa scrofa) is rapidly expanding. Given the significance of reference values for biochemical analysis for diagnosis of pathological processes and the limitation of data in the literature on this species, Blood samples were collected for determination of biochemical values in 160 wild boars from 180 to 300 days old, clinically healthy farms. The reference range for creatinine was similar to the normal range for swine (1,0 – 2,7mg/dL). There were differences between genders, only for the determination of urea, where the males were higher, although similar to pigs (10 – 30mg/dL). The females, with values from 13.03 to 44.78 mg / dL, do not have statistically significant.

Ecologia alimentar de Tatu-Peba, Euphractus sexcinctus (Linnaeus, 1758), na Fazenda Nhumirim, Pantanal da Nhecolância, MS

Studies on feeding ecology are important tools for the understanding of feeding strategies and niche dynamics. Information on the type of food consumed, how, and where it is acquired, enable the elucidation of species behavioral, evolutionary and ecological aspects. The diet study based on fecal material enables a low-cost, informative research and avoids the sacrifice of animals. The general aim of this study is to characterize the diet of Euphractus sexcinctus, the yellow-armadillo, based on fecal samples, to contribute with additional information on their feeding habits. The study was undertaken at the Nhumirim ranch, Pantanal da Nhecolândia, MS, during the months of February and March, 2014. The fecal material was collected during the manual capture of the animals and oven dried at 60°C. The food items found in the feces were sorted using a magnifying glass and separated in the following categories: plant matter, invertebrates and soil. Invertebrates were identified to the order level and the plant matter to the lowest taxonomic level possible. Aiming to evaluate the invertebrate availability in the soil, pitfall traps were installed next to the location where individuals were captured, during the months of April and May. We were able to estimate the frequency with which item was consumed during the studied period, and if there is a relationship between the frequency of consumed invertebrates and their availability environment. Among the analyzed samples, we could observe the frequency of occurrence (FO) of plant matter, invertebrates and soil in all the samples. The main invertebrate orders found in the samples were: Coleoptera, Orthoptera and Hymenoptera, with FO of 100%, 100% and 87,5%, respectively. Seeds were found in 100% of the samples. The FO of the Byrsonima orbignyana was high (62,5%), and evidences the potential of the yellow-armadillos as seed dispersers. The use of other techniques, such as the micro-histological...
