Abstract
The shell eggs are the membrane that performs a number of vital functions in embryonic development of birds. To one of the important factors that affect the process of forming the shell belongs its content of trace elements. The content of minerals of shell eggs of struthio camelus held in intensive system within the natural habitat of Western Ukraine in low nutrient content in feed rations compared with the optimum content of mineral elements are monitored in this work. The basic feed ration was herbal mixture that consisted of Phleum pretense, Arrenatherum elatius, Trifolium pratense, Trifolium repens, Alopecurus pratensis. Empty and fresh shell eggs poultry aged about three years are used for a trace element analysis. Monitoring of trace element composition of shell eggs of Struthio camelus with the establishing of etiological factors in the development of these birds in their natural habitat is temperate continental climate in Western Ukraine is the aim of this paper. Shell egg (fresh) contains slightly higher levels of nutrients content in comparison with shell eggs (empty) of Struthio camelus. Obviously, it can be connected with denaturation of the mineral composition of shell eggs during certain time intervals. The lack of mineral content in feed rations of Struthio camelus leads to disruption in the incubation period. This indicates the relationship between the mineral content in the feed, consuming birds and content of trace elements in shell eggs. Shell eggs of Struthio camelus are an indicator of the content of nutrients in the embryo of birds. Monitoring of trace element composition of shell eggs is of great diagnostic value in establishing the diagnosis of internal changes and pathological defects of those birds.
