Response of Turkey Breeder Hens to Vigofac and Fermacto Supplementation

Abstract Two commercial fermentation products, Vigofac and Fermacto-500, were tested in diets for turkey breeder hens to determine if they would have any influence on reproductive performance. These were tested in separate studies and were used to supplement both corn-soy diets and diets containing 5% fish meal. Vigofac at 1% of the diet supported a significantly higher rate of hatchability when added to corn-soy diets and a numerical but non-significant improvement when added to diets with fish meal. Fermacto-500, fed at 0.075% of the diet, significantly increased the number of eggs per hen when added to diets with fish meal with a numerical but non-significant improvement in production when added to corn-soy diets. The use of these or similar types of commercial fermentation products may be of value in supplementing the diets of breeder hen turkeys.
