التقييم الاقتصادي لمشروعات تسمين النعام في مصر.

The ostrich fattening project is considered one of the modern alternative agricultural activities in the Egyptian agricultural sector. The research aimed to a set of objectives, namely explaining scientific information about ostriches, and the structure of inputs, outputs and costs for ostrich fattening projects was studied, and economic efficiency indicators and investment efficiency indicators were calculated. The research relied on published secondary data, as well as primary field data collected from 10 farms specialized in ostrich fattening. To reach the objectives of the research, two types of economic evaluation were used.(A) The animal farm budget was used. (B) An analysis of the project by calculating lists of cash flows for the ostrich fattening project and estimating efficiency indicators. The most important results were: (1) Using the breakeven point, the study project can be avoid: (i) decrease in the current level of farm gate selling prices (by 15.6%), (ii) an increase in the current levels of be feed prices (by 21.2%). (2) Using the switching value technique, the study project can be avoid: (i) Decrease in the current level of farm gate selling prices (by 6.6%), (ii) An increase in the current levels of be feed prices (by 8.7%). (3) The marginal substitution relationship(i) Between the farm gate price of live weight and the average marketing live weight. (ii) Between the average farm production scale and farm gate price of live weight is also diminished rated. The research recommends the necessity of creating a market for ostrich products, and paying attention to scientific research in this field. [ABSTRACT FROM AUTHOR]
