“We’ve been very luck with conditions, warm with the right amount of moisture, and as a result, grass growth has been excellent this autumn. Over the past week or so it’s been noticeably cooler in the morning and day-length is shortening, so I’m expecting growth to come crashing down pretty quickly in the next week,” says George.

“At the moment, we’re ahead of our grass budget and are on a 40-day round. We’re aiming to take about 2,100kg DM/ha through the winter. Last year we took 1,800kg and we were a bit tight in the spring.

“The plan is to house the cows a bit earlier than last year (instead of the end of November, the end of the second week) and get them out a bit earlier. We’re calving about a week earlier than last year (cows from 18 February and heifers from 10 February) and have more cows, so I’m keen to make sure we have enough grass going through the winter.

“At the moment, cows are just on grass and concentrate and we’ll keep them on that for a couple more weeks. Before we house fully, we’ll look to house them all at night and switch on to silage at this point.

“We weigh the calves born this spring and the bottom quarter are housed a bit early but the rest will go into December on just grass.”
