dwf thanks so much for that explanation- you truly are our very own agricultural story editor. Glad it is grounded in realistic farming practice.
I'm a bit torn. I like the general storyline with Ruth getting her mojo back and the relationship problems being ironed out, but the whole way that she and David go about running their business seems so haphazard and unprofessional. On the one hand Ruth is supposed to be the dairy expert, yet the suggestion was that she had no idea the business was in real trouble without David pointing it out to her (of course that turned out not to be true, but why would he ever have thought that?).
Shouldn't they have some sort of proper pseudo- corporate structure in place, with regular meetings and voting conventions?
There even appeared to be some suggestion from David that he might redact the figures he was sending her- how could he even have contemplated that?
In the episode David did point out to Ruth that she had been the one to push to go over to Autumn calving. That does ring a bell and, like other posters, I had a vague recollection that this was quite a big upheaval and inspired by practice in New Zealand. What were they doing before they went to Autumn calving? Presumably not the system she wants to move to now?
They also changed cow type once before I think, but that was the beef cattle, right?
I thought they made Jill sound like a total imbecile with her "ooh lovely creamy milk from Jerseys" and fruitcake comments.
