Abstract:
The aim of this study was to evaluate the acceptance of a fattening feed for turkeys by using sprouted barley-corn. Germination is used to improve the nutritional value of grain seeds. In addition the tocopherol-/tocotrienol-ratio is shifted in favour of the tocotrienol-content. Investigations show that tocotrienols have a higher antioxidant capacity than tocopherols. As secondary aim the effect on the humoral immune response of turkey poults was investigated. Two experiments were conducted in the current study. The turkeys were fed diets containing 28 % of starch of sprouted barley-corn and 10 % bruised barley-sprouts. They were vaccinated against Newcastle disease virus (NDV) at the age of two weeks. Anti-NDV antibody titers were measured on the day of vaccination, in week 5 and at the end of the trial, in week 8. Feed intake, body weight gains and feed conversion (kg feed/kg weight gain) were within the normal range in both experiments. The acceptance of sprouted barley-corn and starch of sprouted barley-corn and its use as fattening feed was shown by the results of feed consumption and feed conversion. Diets containing sprouted barley-corn can be used as feed, but effects on humoral immune response of turkey poults could not be observed.
