Up in the clouds
...sorry, I've only just registered and it's only because I'm working late (home office) that I'm catching these. But I wonder if it's worth you asking your supplier for 'dry' haylage? I do and it's not the lovely, juicy sweet stuff you'd normally get (not that he'd not love that!) but he just can't have it. But it definately makes a small degree of difference and worth a try.
Yes the first question he asked us was 'would you prefer 'dry' haylage?. Unfortunately the Westphalian would be much better on hay but it just isn't possible. The other 2 were a bit runny when we first changed to haylage but seem to be ok without the balancer/pp now that they have become accustomed to the haylage. I think we'll have to try Brewer's yeast for her.
