2. Growth inhibition of Staphylococcus aureus and escherichia coli strains by neutralizing IgY antibodies from ostrich egg yolk
Ostrich raising around the world have some key factors and farming profit depend largely on information and ability of farmers to rear these animals. Non fertilized eggs from ostriches are discharged in the reproduction season. Staphylococcus aureus and Escherichia coli are microorganisms involved in animal and human diseases. In order to optimize the use of

3. Enterobacteria isolation in ostrich eggs (Struthio Camelus)
This study was conducted to determine the presence of enterobacteria in the eggs of ostriches reared on a farm with a history of reproductive failure. Ninety samples from twenty eggs were submitted to bacteriological tests. The results showed Enterobacteria growth in 100% of the eggs. The microorganisms isolated were Hafnia alvei in 50% (10/20), Serratia spp

4. Behaviour of captive Ostrich chicks from 10 days to 5 months of age
The behaviour of ostrich chicks bred in captivity was studied by using groups with 30 birds in five age groups: from 10 to 40 days of age; from 41 to 60 days of age; from 61 to 90 days of age; from 91 to 120 days of age and from 121 to 150 days of age. Six birds at each age were ringed around one of their feet and observed for four consecutive days for eight

5. Serosurvey of selected avian pathogens in brazilian commercial Rheas (Rhea americana) and Ostriches (Struthio camelus)
Ratite farming of has expanded worldwide. Due to the intensive farming methods used by ratite producers, preventive medicine practices should be established. In this context, the surveillance and control of some avian pathogens are essential for the success of the ratite industry; however, little is known on the health status of ratites in Brazil. Therefore,

6. Ocorrência e sazonalidade de parasitos gastrintestinais em avestruzes (Struthio camelus) de três faixas etárias em uma criação no Município de Areal/RJ. / Occurrence and seasonality of gastrointestinal parasites of ostriches (Struthio camelus) for three ages groups in one farm in Areal/RJ.
Ostriche breeding has recently achieved commercial importance around the world. It is important to know the parasites those affect animals in commercial farms, as infections can reduce the weight gain, compromise reproductive potential and lead animals to death. Brazil has great environmental differences among its regions, depending on weather conditions and

7. Parasitos gastrintestinais de avestruzes (Struthio camelus) de diferentes idades e sua ocorrência nas épocas seca e chuvosa em um criatório no Município de Itaboraí, Estado do Rio de Janeiro. / Gastrointestinal parasites of ostriches (Struthio camelus) of different ages and their occurrence in the dry and rainy seasons in a farm in Itaboraí City, State of Rio de Janeiro.
Ostriches are susceptible to many diseases and until recently, many of them are unknown and can affect these animals when it comes to commercially breeding. In Brazil, the commercial establishment has been initiated 20 years ago, but already there are reports about the diseases that can affect these birds. The objectives of this study were identify morpholog

10. Quality parameters of the tibiae and femora of ostriches
An experiment was carried out to establish mean bone quality values of the tibiae and femora of ostriches and to evaluate these bones. The right leg bones of 10 males and 10 female African Black ostriches were evaluated. Birds were radiographed immediately after slaughter (during bleeding), with the aid of a portable X-ray apparatus. The obtained radiographs

11. Estudo do perfil sérico dos hormônios esteróides (estradiol e progesterona) e do comportamento reprodutivo de fêmeas jovens de avestruz (Struthio camelus) criadas no Brasil / Study of the steroids hormones profiles (estradiol and progesterone) and the reproductive behavior of young female ostriches (Struthio camelus) farmed in Brazi
The purpose of this work was to study the serum levels of estradiol and progesterone and analyze their relationship with the development of the reproductive behavior in young female ostriches (Struthio camelus) during sexual maturity. The first experiment studied two young females, through blood samples, three times a week, for measurement of estradiol and p

12. AVALIAÇÃO BIOLÓGICA E FÍSICO-QUÍMICA DA CARE DE AVESTRUZ (Struthio camelus) E SEU EFEITO OS PARAMÊTROS BIOQUÍMICOS EM RATOS / BIOLOGICAL EVALUATIO AD PHYSICOCHEMICAL OF OSTRICH MEAT (Struthio camelus) AD THEIR EFFECT O BIOCHEMICAL PARAMETERS I RATS
The ostrich meat is being introduced in the market for meat as a healthy alternative when compared with most other meat, because it has low content of total lipids, saturated fatty acids and calories. Despite these benefits reported in the scientific literature on the ostrich meat, there are few jobs in relation to protein quality and effect of the consumpti
