Ostrich (Struthio camelus) production is a relatively young industry and there has been little research on ostrich welfare during pretransport handling and the transportation process. A heavy body with a high center of gravity makes ostriches' handling and transportation problems different from other livestock. The main objective of this study was to investigate the effects of the pretransport ...

In the last decade ostrich farms spread throughout the world as an alternative source of investment. Although previous studies have reported hematology and biochemical values for ostriches from several regions of the world, little information is available regarding leukocyte morphology. This study reports the morphology and ultrastructure of ostrich leukocytes and hematology and biochemical val...

Microspectrophotometry was used to determine the absorbance spectra of both rod and cone visual pigments and oil droplets from the retinae of the ostrich (Struthio camelus) and rhea (Rhea americana). Light and fluorescence microscopy of whole fresh tissue mounts were used to determine the relative numbers and distribution of oil droplets in the retinae. Both species possessed rods, double cones...

While there is a reasonable volume of literature available on the physiology and ecology of the emu and ostrich there is very limited published information on their specific nutrient requirements. This paper attempts to summarise the information available and draw comparisons. The ostrich has been shown to utilise plant fibre with an efficiency equivalent to mammalian herbivores. The emu has a ...

The present study investigated the distribution of nerves in the oviduct of the sexually immature ostrich. The presence of protein gene product 9.5, neurofilament protein and neuron specific enolase nerve fibres were demonstrated in the infundibulum, magnum, isthmus, shell gland and vagina. Nerve fibres containing protein gene product 9.5, neuron specific enolase and neurofilament protein were ...

The paranasal air sinuses and nasal cavities were studied along with other cephalic spaces (brain cavity, paratympanic sinuses) in certain dinosaurs via CT scanning and 3D visualization to document the anatomy and examine the contribution of the sinuses to the morphological organization of the head as a whole. Two representatives each of two dinosaur clades are compared: the theropod saurischia...

The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 Afri...

Starting from the biomechanics principle, the three-dimensional (3D) composite model of ostrich foot locomotion system was established using dissection, medical scan modelling, reverse engineering (RE) and finite element (FE) analysis technology. Simulation calculation on the model under three groups of different loads was performed. Meanwhile, plantar pressure test on the in vitro ostrich foot...
