December Sire Summary: Depth, Balance and Real Progress

This December proof run arrives at a time when UK milk output is rising and prices are softening, which puts real pressure on farm margins. Strong, efficient and long lasting cows are more important than ever, and this update shows that Cogent is making its biggest investment yet to support producers. With 26 new sires added, the programme now offers more depth and flexibility across all key traits.
