l. Dilute fish odours from four distinct char populations elicited differential responses from char olfactory bulb cells. 2. Differential sensory responses produced by odours from migratory and non-migratory populations of char suggest that fish odours could act as pheromones which help guide homing in these salmonids. 3. Skin mucous may well be the principal source of odorants released by the ...

Lipids are an important nutritional component of the avian egg. A review of the literature was completed to determine the fatty acid compositions in egg yolk from some avian species. Additionally, the nutritional influence of lipid and lipoprotein content on the plasma of male participants during 30-day feeding was discussed. The ostrich eggs had the highest unsaturated fatty acid and the lowes...

A slow pyrolysis of pinewood was investigated in this paper. Through the briquette process, the pinewood sawdust becomes molded biomass. The molded bio-char was produced from molded biomass with different pyrolysis factors, and the bio-char’s heating value, char yield rates, and physicochemical and morphological properties were investigated. Molded bio-char’s characteristics depended principall...

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...
