This study aims to estimate the investment efficiency indicators in commercial production of eggs, quantify the potential impacts due to major technical and economical variables changes on investment efficiency, and estimate the efficiency of using production resources in eggs production for small enterprises. A sample of enterprises in both Ismailia and Sharkia governorates were surveyed in 200212003. The results could be summarized as foilows: 1 Feeding and labors explain 94% of total variance of egg production in the studied sample. Moreover, these factors were used in economic stage of production function stages. 2 The studied entertñses recorded a highly investment efficiency. 1RR was 55% for white strains and 68%forbrowri strains. 3-. If production increased by 5%. IRR will be increase to 71% for white strains and 79% for brown strains. 4a If eggs seJI price decreased by 10%. IRR WIll be decrease to 28% for white strains and to 37% for brown strains. 5 If feeding price rncreased and eggs sell prices decreased at the same time by 10%, IRR will be decreased to 9% for white strains and to 19% fw brown strains. These results confirmed that the enterprises that use the white strains were more sensitive to all studied altematives compared with enterprises that use brown strains.
