stocking millet and rye

[Buckaroo]

i have acess to some creek bottoms for planting. i was thinking about planting half of them into oats and rye and the other half into millet just for grazing with cattle. there is about 50 acres total. i am trying to figure out what i could figure the stocking rate to be and if this would produce good feed for the cattle to graze. i figured oats and rye so i could get earlier grazing till the millet is ready and than move to the millet. i can tell you that on any givin year i can expect these bottoms to produce around 6 bales weighing 1500 lbs per acre a year like this were we have been wet we got 12 bales 1500lbs per acre from millet. these bottoms i can get would be the same thing. i am just looking for anyone that would give me some insight about grazing something like this and what i can ecpect the stocking rate to be roughly on just a regular year. thanks for the help.
