Getting more from grass
Thanks to Dr George Fisher for a really interesting article in the excellent June issue of British Dairying magazine.
Dr Fisher explains “We don’t tend to think of grazed grass in the same way as other feeds like silage or concentrate, where we measure the energy content to judge its quality. But, we should do, because the more milk we can get from the cheapest megajoules (of energy) on the farm, then the more profitable our systems will become on a per litre basis.”
Dr Fisher has produced a table to illustrate the real value of grass in producing milk against other feeds and forages.
The table and the full article can be viewed here.
Dr Fisher says “The challenge is that managing grazed grass takes time, but the rewards are worth having in any system”.
In financial terms, he calculates that simply raising milk from grass from 1,500 litres to 2,500 litres whilst maintaining milk yields can cut costs by £40 to £80 a cow – a saving of between £10,000 and £20,000 a year in a 250 cow herd.
