<p><strong>Molybdæn</strong> (Mo), <strong>krom</strong> (Cr), nikkel (Ni), <strong>tin (</strong>Sn), <strong>vanadium</strong> (V), <strong>fluor</strong> (F), <strong>silicium</strong> (Si) og arsen (As) regnes også med til de essentielle mineraler. Behovene for disse mineraler er ikke fastlagt. Det naturlige indhold i foderet er normalt nok til, at dække behovet, og disse stoffer bliver normalt ikke tilsat i foderet. Molybdæn og fluor kan have giftvirkning i større doser.</p>
