Abstract

Cultivation of crambe abyssinica gains increased importance due to the high erucic acid content in the oil. After pressing or extracting the oil, pressed cake or extracted oil meal are obtained, which may be useful feeding stuffs for pigs and cattle.

Crambe oil contains up to 56 % erucic acid related to total fatty acids. Glucosinolat contents were found to be 50 or 77 mmol/kg dry matter (DM) in the cake or in the meal. The energy contents of crambe cake and meal were analysed to be 10.6 or 9.3 MJ ME /kg DM for pigs and 7.2 or 6.0 MJ NEL/kg DM for cows. Incorporation rates of 10 % crambe cake in pig diets decreased live weight gain significantly from 782 g/d in controls to 742 g/d in the experimental group. The increased intake of glucosinolates results in enlarged livers and thyroid glands. Crambe by-products fed to dairy cows resulted in a decreased intake of concentrates, when the incorporation rate in the concentrate amounted to 30 %. Milk yield decreased correspondingly.

  Zusammenfassung

Crambenebenprodukte sind durch mittlere Gehalte an Rohprotein und hohe Gehalte an Rohfaser und Glucosinolaten gekennzeichnet. Infolge der hohen Rohfasergehalte ist die Verdaulichkeit der organischen Substanz beim Schwein niedriger als beim Wiederkäuer. Dies spiegelt sich in den ermittelten Energiekonzentrationen wider.

Die Verfütterung von Crambenebenprodukten führte bei Mastschweinen zu verminderten Zunahmen sowie zu stark vergrößerten Schilddrüsen. Bei Milchkühen sank die Akzeptanz der Kraftfuttermischungen und dadurch bedingt ging die Milchleistung der Tiere zurück.

Aus den Ergebnissen ist die Empfehlung ableiten, dass Crambenebenprodukte in der Fütterung von Mastschweinen nur begrenzt einsetzbar sind. Ein Anteil von 5 % in der Futtermischung sollte nicht überschritten werden, beziehungsweise sollte die damit verbundene Glucosinolataufnahme 280 mmol nicht übersteigen.

Aufgrund der hohen Rohfasergehalte und der besseren Verdaulichkeit sind Crambenebenprodukte effektiver in der Fütterung von Wiederkäuern einzusetzen. Dabei sollte beachtet werden, dass der Anteil an Crambepreßkuchen oder -extraktionsschrot im Kraftfutter für Milchkühe 15 % nicht übersteigt.
