Results from Cobb-Douglas production function analysis show that dry fodder, green fodder and daily labor hours have positive significant effect on milk production, while herd size has negative significant effect. Furthermore, the addition of estimated coefficients is less than 1, indicating a decreasing return to scale in milk production. These results suggest that small sized dairy farms are more productive and profitable; howe...
