✦ Synopsis
Four silage types were prepared from raw and cooked whole herring, whole mackerel, byproducts from the ülleting-line of cod and saithe, and from the viscera of cod. Each silage type was stored at 4, 20 and 50ÄC for 48 days. The raw materials were analysed fresh and after 2, 4, 8, 16, 32 and 48 days of storage. Dry matter, crude protein and total fat were not aþ ected by the diþ erent storage temperatures or the length of the storage period. Neither was there any change in amino acid contents. Chemical composition in diþ erent silage types reýected the amounts in the raw materials used for silage production. Hydrolysis, on the other hand, varied with the type of raw material used for silage production as well as with the temperature under which the silages were stored. Cooked raw materials did not show any change in hydrolysis during storage.
