ABSTRACT: This study discusses the epidemiological, clinical, and pathological characteristics of two outbreaks ocular infection in ostriches (Struthio camelus) caused by trematode Philophthalmus sp. The occurred states Ceará Rio Grande do Norte Northeast Brazil. Ostrich farming was categorized as semi-intensive with free access to weir river. clinical symptoms for included nictitating membrane...

--We assayed restriction-site differences in mitochondrial DNA (mtDNA) within and among populations of the Ostrich (Struthio camelus) throughout much of its African distribution. Little genetic diversity was evident among samples drawn from localities throughout southern Africa (S.c. australis), while deep divisions in the mtDNA gene tree exist between representatives of the eastern (S.c. molyb...

Therizinosaurs represent a highly unusual clade of herbivorous theropods from the Cretaceous of North America and Asia. Following descriptions of the basicrania of the North American therizinosaurs Falcarius utahenisis and Nothronychus mckinleyi, the craniocervical musculature in both taxa is reconstructed using Tyrannosaurus, Allosaurus, and some extant birds as models. These muscles are subdi...

the important of ostrich breeding have been increased in the iran as other country around the world. lack of sexual dimorphism in many species of birds including ostrich (struthio camelus), making it difficult to differentiate between males and females, especially in young birds. this can be problematic for breeding programs. blood samples from randomly chicks in the first days were collected a...

The one-humped camel (Camelus dromedarius) is a seasonal breeder with a relatively short breeding period, when increased ovarian activity is exhibited (Shalash, 1965,1980; Nawito, Shalash, Hoppe ¿St Rakha, 1967 ; Novoa, 1970). In Israel, the normal breeding season occurs from December to early April. Female camels come into heat during this period and exhibit mainly follicular activity; there i...

The one-humped camel (Camelus dromedarius) was first introduced to German South West Africa (Namibia) for military purposes in 1889. Introductions to the Cape of Good Hope (South Africa) in 1897 and Rhodesia (Zimbabwe) in 1903 were initially with a view to replacing oxen that died of rinderpest. Disease risks attendant on these introductions were recognised and to some extent guarded against. T...
