157 acres is alot. I say my land is 10, actually a bit more but 10 is a nice number. Can you have farm land without using it for meat? Yes, BUT you HAVE to be aware of NOT using the land for animals. Even though I had 4 acres mowed and baled, I'm still over-run with grass, yet earlier this year, the place was bare. I've let the neighbour run on 20 cattle just to tidy up the place as my cattle (all 3 of them) and few sheep are struggling. Once bare, (give the mob a week) they'll depart and the grass will grow again. No meat? When Larry dies, what do you plan to do with his body? Years ago we buried, foot & mouth stopped that!
I understand pets, mine are pets. I have a never lambed Ewe, she's a pet and 7 in December. She has a hairy wether to keep her company. I reared both of them! My cattle are docile monsters that I love, BUT if there is a problem, I am well aware that they will go either into the food chain or into the incinerator.
I do have a tup on the place doing his duty, hopefully I'll get some lambs, if I don't get too attached I'll eat them, if the Wiltshires throw a nice ewe lamb and it sheds, I'll give it a chance (tup is Dorset Down) boys will depart for auction.
You know, back in 2006, I had lots of sheep that I put in lamb to a frisky little lad, Harry, then I sent him off and we ate him. Now, I can't do that, nothing to do with Veganism etc, just that I get more emotionally attached. I DONT feel guilt eating the little blighters its just that I have to have it in my head, 'I'm going to eat you!' Think like that for a few months, when the time comes, you can do it!
There HAS to be a balance between the land and the animals and cost. My objects MUST cover their own feed/bedding costs, I'm a mug so my time is free!
If you are going to rent your land to a farmer then you have to accept that the farmer is feeding the people one way or another BUT if you take your land out of production, it's not just grass that grows, weeds do to and they multiply! Something needs to eat the grass whether it's horses, sheep, cattle, goats etc. But with that amount of land it makes me wonder what the arrangements were before if a farmer were to rent it, did they have it before?
If it is your land then it is your choice BUT unless you have a bottomless pot of money you have to look at what is best for you AND the land.
