At the minute 3 kilo to all .
When the weather settles down and the grass supply is more even i might drop a kilo but probably not !!!
As long as a kilo of meal is cheaper than a litre of milk you cant really lose
The few pound of meal at grass kept the cow right and was a cheap vet my late father reckoned and as i get older i realise he was right about that as he was about most things ,
