Performance efficiency of human labor input is considered one of the most important factors affecting enhancement of the production. Evaluation of performance shows the level of labor performance efficiency, to know the strengths and weaknesses in the completion of the various production processes, and involves comparing the actual level of performance with respect to target or desired level, under a set of standards and specifications determine performance of the worker. There are many variables play an important role in the efficient and effective performance of the worker as a human factors of production, impacting directly on the deviation of the operating current level of employment, which achieves economic efficiency. Therefore, the research problem lies in the nature of the determinants of the efficiency of human labor input, in the light of the available skill levels. On the basis of the research problem, the objective of the research represented is to investigate and determine the most important factors affecting the efficiency of labor performance, and thus the possibility of developing a preliminary vision for the classification of agricultural labor according to skill levels required. The study applied limited dummy dependent variables models. Cross section data were collected from Corporation for Animal Wealth. Stratified sample was chosen, and consisted of four activities in the fields: livestock, milking, poultry, and milk processing. Important variables affecting the performance efficiency of workers subjected were estimated via logit, probit, and tobit regressions. The results indicated to that the variables explaining performance efficiency were: incentives, experience, and worker's wage in livestock field. As for workers in milking field were: wage, incentives, and experience, and for workers in poultry field and dairy processing were: incentives, wage and experience. Finally, the study recommended the need for attention to the training of workers and transfer training, which fits the needs of the labor market, and the need to prepare professional classification to access the names and professional qualifications and real skills inside agricultural branches, and therefore can through this classification judging the efficiency of the labor. Need to exchange agricultural wages commensurate with the level of worker productivity and performance, so as to improve the performance of the human labor input in all sectors of the Egyptian agricultural production.
