This study was aimed to investigate use of Taguchi method in animal researches which is as an alternative to factorial experiments. Modeling real-world phenomena often requires more than one factor to explain changes on response variables. Factorial designs are very powerful statistical tools because they allow a researcher to simultaneously test the effects of multiple factor-level combinations on response. But sometimes factor numbers and their levels used in the factorial experiments as difficult and expensive. Taguchi method is a design by using orthogonal arrays which minimizes the time and cost of experiment compared with factorial design. Also, reducing the number of experimental units allow to reduce the effects of uncontrollable factors. Particularly, studies to test a large number of its good results at less cost than expanding the use of Taguchi method. Application data taken Erbeyli Fig Research Station Management. Experimental design of data was 3x3x2 factorial design. Factorial experiment and Taguchi method results were compared. Taguchi method was determined the best combination of period, breeding and genotype which had effect on egg weight with a less number of experimental units. Taguchi method which is not commonly used today should be promoted and popularized as an alternative.
