The current prices of fertiliser and feed mean that there has never been a better time to take full advantage of grazed grass. Using a rising plate grass meter to assess grass covers gives some science to knowing whether cows appetites are met or not, how much to give the cows, and whether they have grazed the paddock tightly enough.

Rules of thumb are as follows:

Turn cows into a grass cover of around 2,800 – 3,400 kilos of grass dry matter per hectare

Pull cows out of pasture when cover down to 1,500 kilos of grass dry matter per hectare

Aim for a 21 day grazing rotation

With the current daily grass growth rates – upto 100 kilos dry matter per hectare per day – many pastures are getting too strong for grazing. In these circumstances it is worth skipping paddocks, cutting some paddocks for silage or even mowing and grazing some swaths behind an electric fence.

Measuring the grass covers, and recording on a weekly basis can mean an extra 2-3 litres from grass per cow per day. This is equivalent to saving £860 per month on feed costs for a 100 cow herd.

With interest expressed from customers, we are looking at running a grazing and plate meter course for any interested farmers. If you would like more details please contact the office.
