Evaluation of probiotics as feed supplements for ostrich chicks
Production in farming of ostriches (Struthio camelus) is limited by the high mortality rate of ostrich chicks. Chicks which lack a well established microbiota are more susceptible to potentially fatal pathogenic infections. Therefore, the mortality rate may be decreased by establishing the correct …

The development of probiotics for use in the ostrich farming industry in South Africa
Ostrich farming in South Africa is an important industry but it often suffers from high mortality rates among the ostrich chicks. This is thought to be due in part to environmental stress, leading to the delay in the development of the microbiota, thus making invasion by pathogens likely. Very …

An investigation of ostrich eggshell bead size variability and the introduction of cup morphology
Ostrich eggshell beads are valued not only as decorations but also as important social and cultural symbols by those who create and use them. Originating in the Middle Stone Age (MSA), OES beads are still produced by several African communities. Early investigations of OES beads recovered from …

Molecular characterisation of the fibre-digesting bacteria isolated from the ostrich (Struthio Camelus var. Domesticus) hindgut
… strains that have been isolated from the ostrich hindgut, have successfully been identified with the aid of PCR amplification of the 16S rDNA genes and sequence analysis using the BLASTN search of the GenBank database. The nucleotide sequences were determined either through direct …

Understanding Highly Pathogenic Avian Influenza outbreaks in Western Cape Ostrich industry: did network dynamics enhance vulnerability? Christine Moore.
… analysis to understand how the movement of ostrich stock between farm locations in the Western Cape, South Africa may have contributed an epidemic outbreak of Highly Pathogenic Avian Influenza (HPAI) within the ostrich industry in 2011.

Untersuchung zum Verhalten und der Haltung von Afrikanischen Straußen (Struthio camelus) unter deutschen Klimabedingungen
… aim of this study was to attain knowledge about ostrich behaviour in captivity and to conclude from that to appropriate animal husbandry under German farming conditions. Special concern was given to the use of the stables and the influence of different climate parameters. Recommendations for the …

Biologically Inspired Engineering for Protein Stabilisation
… in the fossil record has been shown for ostrich eggshell proteins and the most durable proteins are known to belong to the C-type lectin-like protein family. It is thought that at least one C-type lectin-like protein is found in the eggshells of every species. The most well known C-type …

Mobility and hydrodynamic implications of the long neck in plesiosaurs
… against physical and digital manipulation of an ostrich neck. Neck vertebrae from the posterior-most half of an ostrich neck were manipulated to determine dorsoventral and lateral RoM at successive stages of dissection. Neck vertebrae from four plesiosaur specimens were digitised to study RoM, …

Impacts of degradation on critically endangered Oudtshoorn Gannaveld
… Karoo region of the Western Cape Province, ostrich farming has degraded large areas of natural vegetation, particularly in the Gannaveld habitat of the Oudtshoorn basin. Little quantified vegetation data exists on the impacts of degradation and the composition of the Gannaveld vegetation …

A microbiological and molecular study of campylobacter and related species isolated from ostriches (Struthio camelus)
… for campylobacter, very little is known about ostriches as a vector for these organisms. What is known, however, is that these birds can and sometimes do get infected. Studies by various researchers have provided evidence that various species of animals shed Epsilonproteobacteria in their …
