A neighbouring farmer recommended that he should use Optipartum-C+ having seen how it improved overall milk yields and cow performance.
With his 24% starch ration, he added OC+ and saw a 2 litre improvement in yield in 30 days. Drilling deeper, we can see where this comes from by comparing DIM yields pre and post adding the OC+.
The clear upward trend shows yields are up across stages of lactation. The farmer also commented "my fat has increased by 0.30% and protein by around 0.10%".
