The best way to check is by testing them – we recommend 8 liver biopsies to check copper levels, and 10 blood samples to check selenium and magnesium levels.

Your vet can then review your mineral supplementation plan with you, to ensure your animals are getting what they need. 

Don’t forget about your heifers that have just come home – their mineral status can be very different to your herd.
