title: [Testing of the digestibility of crude nutrients and of the applicability of tapioca for laying hens and young chickens].
abstract: By means of the difference method an apparent digestibility of 88.3% of the organic matter, 50.4% of the crude protein, 25.1% of the crude fat, 12.7% of the crude fibre and 94.2% of the N-free extractives of Thai tapioca meal was ascertained in colostomized laying hens. It is possible to use 20% tapioca meal in the feed for chickens and pullets without a decrease in performance. Two experiments with laying hens were carried out with 5-30% tapioca. Egg production decreases slightly with a tapioca quota of 10% and more. This is why a feeding limit of 5% is recommended. With 20% tapioca the decrease of performance was 1.5%. Tapioca meal diminishes the intensity of the yellow of the yolks. Cereals may be partially substituted by tapioca in the feed for chickens, pullets and laying hens.
