Provided is the use of an enzyme selected from a carbohydrase and/or protease as a component of a non-viscous animal feed for promoting the absorption of pigments present in the feed. Non-viscous animal feeds are based on cereals such as sorghum, rice and maize, on oilseeds such as soya, canola and rapeseed, or on root crops such as tapioca and cassava. The pigments may be either present naturally in the feed or added to the feed and include such carotenoid pigments as astaxanthin, canthaxanthin, lutein, zeaxanthin and beta -apo-8'-carotenal. Also provided is a non-viscous animal feed and a method for increasing the bio-availability of a pigment present in an animal feed by incorporating 1 x 10<-6> - 1 % by weight of a carbohydrase and/or a protease into the feed. |
