Ostrich eggshells are excellent examples of avian biomineralization. Interest in these is focused on their potential as a food source, example biomaterial for medical and industrial applications, the use fossil remains paleoenvironmental reconstructions. Due to this interest, there some information about aspects eggshell biomineralization, but it scattered different publications limited scope m...

Recently reports on toxocariasis are increasing by serodiagnosis in Korea. A previously healthy 17-yr-old boy complained of headache, fever, dyspnea, and anorexia. He showed symptoms and signs of eosinophilic meningitis with involvement of the lungs and liver. Specific IgG antibody to Toxocara canis larval antigen was positive in serum and cerebrospinal fluid by ELISA. He took raw ostrich liver...

A large incomplete ostrich femur from the Lower Pleistocene of North China, kept at Muséum National d’Histoire Naturelle (Paris), is described. It was found by Father Emile Licent in 1925 Nihewan Formation (dated about 1.8 Ma) Hebei Province. On basis minimum circumference shaft, a mass 300 kg, twice that modern ostrich, obtained. The bone remarkably robust, more so than recent, Late Pleistocen...

In order to enhance knowledge of the nutritive value of ostrich feeds, the in vitro gas production technique was used. Five feeds (corn silage, CS; alfalfa hay, AH; barley, BG; soybean meal, SM; beet pulp, BP) were weighed (~ 1g) in quadruplicate in 120 ml serum flasks and incubated at 39 °C with 75 ml of anaerobic medium and 4 ml of reducing solution. A pool of caecal contents obtained at slau...

Leather is one of the main products derived from ostrich farming. Current rearing practices lead to a high incidence of skin damage, which decreases the value of ostrich skins. In the emu and poultry industry, declawing is commonly practiced to reduce skin damage and injuries. We consequently investigated declawing of ostrich chicks as a potential management practice to minimize skin lesions th...
