Take a look at our standout high ACI sires, bred to bring you:

• More focus on milk volume & quality
• Strong fertility & longevity
• Lower maintenance costs
• Better udders, legs & calving ease

Autumn block-calving allows calving to align with feed availability, delivering strong winter milk yields when prices are at their best.

It’s a system built around efficiency, fertility, and sustainability.

The Autumn Calving Index is designed specifically for autumn block-calving herds, reflecting both the cost of winter milk production and the higher milk price per litre typically achieved at that time of year.

Unlike other indexes, £ACI puts more weight on milk volume (to match winter demand) while still promoting milk quality, fertility, and longevity — the key traits for profitable autumn systems.
