As one of the fastest running animals on land, ostrich’s excellent athletic ability benefits from its unique leg structure. Based idea bionics, this paper intends to obtain a kind robotic structure with similar buffering capacity that ostrich. For purpose, structural characteristics seven-link parallel mechanism are analyzed firstly, having some specific features ostrich legs, such as center ma...

This study provides a reference for the radiographic anatomy of the thoraco-abdominal cavity of female ostriches as a representative of ratites. One ostrich cadaver, 2 adult and 2 growing ostriches were used. Right lateral radiographs produced by a 6-frame technique and 2 dorsoventral radiographs produced by an adapted 3-frame technique were selected and schematic illustrations of these were la...

Abstract Nutrition of breeding female birds can influence egg quality and is therefore extremely important for the development of the embryo and the successful hatching of a high quality chick. We investigated the effect of combining different levels of dietary energy and protein, with accompanied amino acid levels, in the diets of female ostriches on the composition of their eggs. Ninety pairs...

Respiratory diseases caused by bacteria are common to all of ages of ostrich (Struthio camelus). Young chicks, however are more susceptible, and are considered a major hindrance in successful ostrich farming. Using culture dependent techniques, a diminutive prospect of bacterial pathogens and corresponding diseases associated with respiratory system has been described. Here we report the first ...

Fatal pulmonary aspergillosis and AA type amyloid accumulations in the liver and spleen are described in a female ostrich (Struthio camelus). The animal had had respiratory problems and long-term inappetence over an 8-week period. Necropsy revealed that several soft, grayish to white nodules ranging from 1 to 3 mm in diameter were scattered throughout the lungs and thoracic air sacs. Prominent ...

Cloacas of male ostrich chicks that had suffered prolapse of the phallus and cloaca were compared with cloacas of normal ostrich chicks of both sexes from the same area. Heavy infection of the cloacal and bursal tissue with Cryptosporidium sp. was present in all the cases of prolapse, while no cryptosporidia were observed in the normal chicks. Histopathological lesions as described in cryptospo...

background:the bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. objectives:the aim of this research was to investigate the bacterialcontamination status, with emphasis on escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated escherichia coli. methods:ato...

Crimean Congo hemorrhagic fever (CCHF) is a viral zoonosis, which is usually transmitted via tick bites or close contact with infected blood or tissue. This disease can cause a case fatality rate of up to 25%-30% in humans. CCHF Infection in birds is less documented. An ostrich can reproduce viruses and can also play the role of a mechanical vector, by transporting infected ticks without becomi...

newcastle disease virus (ndv) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in iran. therefore, establishing a routine vaccination program against nd in ostrich flocks would be useful in order to reduce the danger of this infection. newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losses ...
