“…Diets deficient in calcium or with a low calcium to phosphorus ratio, are thought to cause long bone deviation in ratites (COOPER and HORBAŃCZUK 2004). Fish meal and meat, and bone meal might be used as a source of calcium and phosphorus in the ostrich diet to prevent any symptoms of deficiencies (ULLREY and ALLEN 1996). Our results reflect this statement and indicate fish and bone meal as adequate sources of minerals for ostriches.…”

SAMArDžijA: The influence of different concentrations of feed additive, based on shell rock and bentonite, on the growth, blood and meat parameters of the African black ostrich (Struthio camelus) in southeast Kazakhstan. vet. arhiv 88, 413-425, 2018. AbSTrAcT Forty-eight 3-month old african ostrich females were divided into four groups: control and 3 experimental comprising 12 animals each. all the animals were fed the adopted diet and the experimental groups additionally received a feed supplement based on shell rock and bentonite, at a rate of 5 g/kg, 10 g/kg and 15 g/kg, respectively, for 9 months. at the beginning and the end of the experiment blood samples were collected for hematological and biochemical analyses. at the end of the experiment, 3 ostriches from each group were slaughtered and the quality of their meat was examined. at 12 months of age the weight of the birds in the experimental groups was significantly higher (P≤0.05) in comparison to the control group, by 11 kg, 13.3 kg or 16.4 kg, respectively. During the experiment, an increase in the number of red blood cells, leukocytes and hemoglobin was recorded, however all tested hematological parameters remained within the range of physiological values. The biochemical blood parameters in all groups of ostriches did not change significantly at the beginning and the end of experiment. however, the levels of total protein, glucose, Ca and P in the experimental groups

“…Unbalanced breeder nutrition expresses as multifaceted nutrient deficiencies in ostrich embryos causing abnormal yolk sac conditions and death during incubation (Hallam 1992). When egg production is forced by continually removing eggs, hens require increased calcium intakes that should be provided as a dietary inclusion of 16 g/kg with ad libitum access to granulated calcium carbonate or oyster shell (Ullrey & Allen 1996). The ad libitum access to calcium might, however, potentiate excess calcium ingestion resulting in a reduction in the absorption and utilization of zinc and, indeed, low‐grade sources of calcium from a limestone source potentially contain contaminant minerals that may interfere with the utilization of other minerals in the ration.…”

The ostrich is an important animal in many livestock industries and in the developing world ostrich production is a valuable source of foreign currency netted from the export of meat and skins. Its successful growth and reproductive performance is dependent upon good nutrition. In Zimbabwe, one of the greatest costs involved in the upkeep of ostrich breeder birds is purchased feed (US$4555.45/10 birds p.a.). In order to cover these costs, the producer needs to ensure an adequate throughput of birds for slaughter. The energy provided by a particular feed source is important for growth and development of the bird. More research is required in ostrich nutrition.

“…That being as it is, with domestication comes human control and influence over factors such as nutrition. Consequently, various studies have been conducted and the results successfully implemented to better understand the nutritional requirements of ostriches (Smit, 1963;Gandini et al, 1986;Du Preez, 1991;Mellett, 1992;Ullrey & Allen, 1996;Cilliers et al, 1998;Brand & Olivier, 2011).…”

The ostrich industry is poised to recover from the recent lifting of the four-year export ban on fresh meat products to the European Union EU). However, during this period profit margins were severely affected and the need to minimize input costs was as important as it ever was, particularly nutrition. The aim of this study was to evaluate the influence of varying protein concentrations in the diets of slaughter ostriches on the production traits. Five treatment diets were formulated for each feeding phase (pre-starter, starter, grower and finisher), with a control diet, two diets that decreased in protein content and two diets that increased in protein concentration. There were three replications per treatment, resulting in 15 camps, which contained 20 chicks each. Differences were found in live weight of the birds at the end of each feeding phase, except for the finisher phase. Differences were found among the diets for dry matter intake (DMI), average daily gain (ADG), and feed conversion ratio (FCR). The control diet and the two diets that were formulated with higher protein concentrations had higher DMI values, better ADG, and more efficient FCR. Differences were found in cold carcass weights and thigh weights for the birds that were exposed to the treatment diets. The results indicated that the birds on the control diet and on the diets containing higher concentrations of protein, although not differing from each other, consistently outperformed the diets with lower concentrations of protein. From a financial standpoint it can be concluded that it does not make sense to increase the protein concentration in the diets beyond that currently used in the ostrich industry, while a decrease in protein concentration resulted in decreased production performance.
