Data from the Agrisearch “Grassland performance and its relationship with profitability on 10 Northern Ireland dairy farms” shows milk from forage ranges from 2260 ltr to 4550.
Two of the farms with this highest margin were managed very differently but also very efficiently, one yielding 6000 litres on 1 t of meal and the other yielding 8700 litres on 2.3 t of meal. Both achieved approximately 3500 litres from forage. This should be a realistic aim for dairy farmers in Northern Ireland.
