How many acres per animal unit in your area? We are running 1 to 1 for pasture and 2 acres to 1 AUM for hayland. Still trying to improve the hayland since some of it was abused for years before we started haying it. I would like to spread some manure on the hayland if it ever dries out enough. We are lated to get a tropical storm this weekend with another 2 to 3 inches of rain.
Sorry, I'm not quite following your figures PATB I count mine in Animal Unit Days per acre (AUDs) rather than acres per AUM. From what you posted do I take it 1 acre of your pasture supports 1 cow for a month but your hay land only produces 50% of that? Those figures seem awfully low or do I misunderstand them?
We get huge variation here across the place because the land varies from good tame to poor tame, good productive bush to heavy bush and also the riparian which we choose to use a lot lighter.
Our best tame does around 100 AUD/acre but it's just touch and go if that is sustainable without depleting the stand. Poorer tame usually does in the 50-80AUD/acre with us but we still have some fields that are in the 30s AUD/acre

By contrast the best bush pastures can do close to 60 whereas the heaviest treed areas only manage 12-15AUDs.
I find these rates are a constantly moving target field to field but overall on the place the average has just been creeping up slowly and sat around 60AUDs/acre last year. The drought this year will reduce that quite a bit. I should add that we use unadjusted AUDs (our cow herd averages 1250lb versus the 1000lb of the true AUD)
Like the other posters I just use experience, records and eyeball yield. I've been doing it since I was a kid and prefer to walk everywhere if possible when checking cows as you are in much closer contact with the ground and the grass. I think the measuring sticks turn off a lot of beginner pasture managers because they seem too complicated. I've seen their eyes glaze over when they hand them out at grazing courses!
With our system of banking grass to graze the following spring counting a fields yield becomes a little more complicated and has to be done retrospectively. For example we grazed some fields in 08 and only took 12-20Auds/acre off them and left them to graze in spring 09. This spring we took 150-175Auds/Acre off some of these fields - much of that was grown in 08 but it also included some fresh growth from 09 so I allocate yield to production year as I see fit. See now I'm trying to make it too complicated :roll: I'll quit now before someone beats me with their grazing stick :lol:
