Ernæringsbehov og fôring for optimal helse og overlevelse av rensefisk - Del 1 berggylt
Lein, Ingrid; Berge, Gerd Marit; Bogevik, André Sture; Bæverfjord, Grete; Hamre, Kristin (Nofima rapportserie, Research report, 2021)Berggylt bør i alle livsstadier tilbys fôr som er prosessert ved lave temperaturer, som agglomerering eller kaldekstrudering, fordi dette gir bedre mineralisering og mindre deformiteter, og også redusert dødelighet hos ... -
Ernæringsbehov og fôring for optimal helse og overlevelse av rensefisk - Del 2 Rognkjeks
Lein, Ingrid; Berge, Gerd Marit; Bogevik, André Sture; Hamre, Kristin; Aas, Grete Hansen; Kortner, Trond M.; Kousoulaki, Katerina; Krogdahl, Åshild; Remø, Sofie C.; Sæle, Øystein (Nofima rapportserie, Research report, 2021)Rognkjeks har et velutviklet tarmsystem, men pH i magen faller først ved 1,0-1,5 gram. Rognkjeksen bør derfor tilbys agglomerert eller kaldekstrudert fôr fram til denne størrelsen. Fôr med 55 % protein, 17 % fett og 6 % ... -
Increasing dietary levels of the omega-3 long-chain polyunsaturated fatty acids, EPA and DHA, improves the growth, welfare, robustness, and fillet quality of Atlantic salmon in sea cages
