Checking the numbers always pays off
At the MDF, rotation length is stable and laser-graded bays are about to come into the rotation, meaning that the graze rest time is likely to lengthen. This is key to maintaining grass growth and good paddock conditions through the colder winter months, and capitalising on the spring flush of feed to optimise milk production.
In the table below, although the MDF is stocked more heavily, grass consumption per cow is a lot higher than the comparison farm. Concentrates are the same, but the other farm is feeding much more hay/silage to maintain feed intake. So, grain intake, total feed intake and NDF in the diet of the cows on the two farms is almost identical. The big difference is the amount of grass on offer, and the impact this has on milk solids and feed costs/cow.
The importance of offering as much grass as possible to each cow is reflected clearly in input costs, production and MOAF/day.
