The process of reducing size of the grains by crushing is normal operation in most of poultry farms. The aim of this study is to evaluate the performance of four poultry fodder mixmilling equipments as a sample of private fodder preparation equipments which widely spread in Egypt. This study included equipments productivity, operation efficiency, energy consumed and cost analysis considering economical management. The obtained results reveal to the following: - The highest mix-milling productivity of 11.563Mg/h, 69.379 Mg/day and 10710 Mg/year for hourly, daily and annual productivity respectively under the use of first equipment at 0.7 cm screen hole diameter and ratios of mixing materials for one Mg was (6() % corn - 30 % soybean - 10 % concentrates). - The highest values of operation, daily utilization and annual utilization efficiency were 90, 67.5 and 57.85% respectively under the use of first equipment. - The lowest value of energy consumed of 0.514 kW.h/Mg under the use of forth equipment at 0.7 cm screen hole diameter and ratios of mixing materials per one Mg was (60 % corn - 30 soybean - 10 % concentrates). - The lowest value of cost of 4.57 and 4.85 LE/Mg under the use of forth and first equipments at screen hole diameter of 0.7 cm
