Questions from the plant
Can D₂, D₃ and hydroxylated derivatives use one analytical report?
Match chemical identity to the relevant test and review feed-use documentation for the target animal.
How should the two potency figures on an A/D₃ premix be used?
Calculate A and D₃ separately. Adding the two values does not give D₃ potency.
