ECONOMICS OF PRODUCTIVE TRAITS OF SOME EGG-LAYER STRAINS UNDER EGYPTIAN CONDITIONS
The study showed that selection for the high egg yield per hen housed is not always economically successful. Selection for the minimum cost(optimum level of egg yield)is economically, recommended. Less mortality rate leads to higher profit per L.E (Egyptian
Pound)of costs, which reflects mainly a higher rate of culled layer-hens as a secondary output of the layer farms? Even though, mortality variation is due to the changes in the farm management and environmental conditions. Therefore, a selection policy in this direction is not economically feasible.
Hibro-strain showed the lowest productive performance of a high instability level and
high cost per egg. The Egyptian improved strain(Dokki-4), although it had a lower egg yield and a higher feed consumption per egg than the NHL strain, both showed the same cost level per egg. This reflects the effect of diminishing return concept on the costs of
