Aspectos de importância na produção racional de avestruzes (Struthio camelus)

Occurrence of antibodies to Toxoplasma gondii in rheas (Rhea americana) and ostriches (Struthio camelus) from farms of different Brazilian regions Ocorrência de anticorpos Toxoplasma gondii em emas (Rhea americana) e avestruzes (Struthio camelus) de propriedades de diferentes regiões brasileiras

This study aimed to verify the occurrence of antibodies against Toxoplasma gondii in rheas (Rhea americana) and ostriches (Struthio camelus) commercially breeding in Brazil. Blood samples from 20 rheas and 46 ostriches (young and adults) were serologically tested using a technique known as modified agglutination test (MAT) at an initial titration of 1:16 for ostriches and 1:25 for rheas. Antibo...

Gastrointestinal nematodes in ostriches, Struthio camelus, in different regions of the state of Rio de Janeiro, Brazil Nematoides gastrintestinais em avestruzes, Struthio camelus, de diferentes regiões do Estado do Rio de Janeiro, Brasil

The ratite group is composed of ostriches, rheas, emus, cassowaries and kiwis. Little research has been done on parasitism in these birds. The aim of this study was to determine the distribution of infections by gastrointestinal nematodes in ostriches in the state of Rio de Janeiro. For this, fecal samples were collected from 192 on 13 farms. From each sample, four grams of feces were used to d...

Avaliação da Qualidade de Documentos de Requisitos Orientado a Aspectos

Recent proposals have looked at the requirements stage, using the aspect oriented programming, trying to separate and after to compose the concerns that are spread and tangled in the requirement document. New factors appear in these requirements documents, such as, crosscutting concerns, size and coupling are not qualitative evaluated, because there are not these metrics. This paper shows a set...
