Optimising Autumn Grass for Spring Success
Farmers are urged to manage October grass carefully to secure spring feed. With strong growth this year, early closing and strategic grazing will ensure enough cover for early lactation cows in February.

Farmers are being reminded that the grass sown in October will be the feed they rely on in February, says Teagasc Dairy Specialist Stuart Childs. With a remarkable rebound in growth this month, many paddocks now have surplus grass that, if left uncut, could become overly heavy and wasteful. Childs advises cutting the excess – a practice uncommon at this time of year – to harvest silage and prevent wastage.
The focus for the coming weeks should be on closing the farm for spring. While autumn grazing may be tempting, it can jeopardise the early‑spring supply that early lactation cows need for optimal energy and protein. The official closing date of 1 December sets a target of 550‑600 kg DM ha⁻¹ for 2.5 LU ha⁻¹ and 700‑750 kg DM ha⁻¹ for 3.5 LU ha⁻¹; monitoring cover in October and early November helps farmers decide when to stop grazing.
Even a single extra day of autumn grazing can reduce spring availability by up to seven days’ worth of feed, Childs notes. By planning autumn grazing with an eye to spring needs and consulting advisors, farmers can maximise returns from both seasons and secure a healthy supply for their herds.
