The reasearch method used was survey with 30 respondents that took by purposive random sampling. The data result were analyzed using multiple linear regression analysis. The result of analysis showed Y= -6.020852 - 0.011653X1 + 0.988392X2 - 0.026411X3 + 0.028399X4 - 0.002938X5 -0.021354X6 + 1.025319X7 + 0.055929X8 + μ. That equation means that each increased in production male ducks was influenced by X1 (Day Old Duck) equal to - 0.011653, X2 (body weight) equal to 0.988392, X3 (cage density) equal to -0.02641, X4 (mortality) equal to -0.028399, X5 (OVAC:medicines, vitamins, and vaccines) equal to 0.002938, X6 (feed) equal to 0.021354, X7 (labor) equal to 1.025319, X8 (growth age) equal to -0.055929. The result of F-test showed that growth weight (X2), mortality density (X4), and labor (X7) variabels has significant. Based on the coefficient of determination of 0.99%, the produkction of male ducks is explained by the variabels in the study, while 0,1% was explained by variables outside the study.
