Dear Alex, (smile) Hi!
The problem about being a human cow, is that only young cows don't sag.
Here's the SFL Dairy's Benchmark, Buttercup, that we are all (at our Dairy) endeavouring to beat at this years Dairy Awards. Butter's is currently producing 6.3ltrs. a day and (sigh) i'm averaging a mere 3.6ltr. so have a lot more work to do yet, including upping my Protein intake.
