Apparent availability of zinc, selenium and manganese as inorganic metal salts or organic forms in plant-based diets for Atlantic salmon (Salmo salar)

Autor: P. Antony Jesu Prabhu, Robin Ørnsrud, Wolfgang M. Koppe, Heidi Amlund, Marta S. Silva, Rune Waagbø, Pedro Araujo, Saskia Kröckel

Publikováno v: Aquaculture

The composition of salmonid diets has changed from the use of mainly marine ingredients to increased use of plant ingredients, and this has an impact on the mineral content and availability. Minerals, like zinc (Zn), selenium (Se) and manganese (Mn),
