The aim of this study was to evaluate the effect of six-hour road transportation on behavioural activities, live weight and traumatic injuries of 40 (20 males and 20 females) ostrich chicks age 3.5 months. The average weight of the birds was 27.7 kg. Four separate journeys were conducted and each vehicle was loaded with 10 ostriches. The behavioural events, environmental data, live weights and ...

Ostrich chick mortality was studied in 2522 chicks that were hatched artificially during the 1999/2000 breeding season. High levels of mortality were observed, with 1978 (78.4 %) of these chicks dying before 90 days after hatching. A total of 46.7 % (1,177) of these chicks died before 28 days of age, and a further 30.7% (801) died between 28 and 90 days post-hatching. Chick mortality to 28 days...

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...

The rapid outbreak of the highly pathogenic H5N1 avian influenza virus and its transmission to humans have induced world-wide fears of a new influenza pandemic. The most effective method for the reduction of the impact of such a pandemic would be prophylaxis with a safe and effective vaccine, as well as anti-viral materials. In this study, we generated the specific antibodies 'immunoglobulin yo...

Ostrich fertility is a very important measure of their reproductive efficiency, hence our interest in studying the ostrich oviduct. In our study, we found in fully mature birds a thin walled region between magnum and isthmus free of glands and considered as an area of transition called zona translucent. Also, the uterus was formed from a cranial short tubal part followed by a caudal large sac-l...

Scientific knowledge of ostrich diseases is incomplete and very fragmented, with specific details on technical aspects of diagnostic and/or screening tests completely absent in most cases. Salmonella Typhimurium is common in multispecies collections and causes mortality in chicks younger than three months on commercial farms, but is rarely found in chicks older than six months, or slaughter bir...

BACKGROUND Ostrich (Struthio camelus) breeds have been gaining increasing significance around the world. The large-scale sex determination of chicks is an important task in the development of these breeds. To date, two PCR-based methods have been established for ostrich sex typing, neither of them intended for large-scale analyses. Here, we report on a protocol adapted to carry out large-scale ...
