We've been doing it for three years now. We are doing it again this year. We use Roundup ready corn, and get the neighbour to custom seed it for us. Last year our costs worked out to about 50 cents a day per cow. We had 130 cow calf pairs on it last year for about 5 weeks, then weaned the calves and put 35 more cows out there. This was on 75 acres, and it lasted about 75 days.
We use the method Denny is talking about, where we divided it into enough for about three days grazing at a time. Otherwise they run around and just eat cobs! :shock: We used the haybine and cut the paddocks out first though, because sometimes in the tall corn they get pretty excited and don't see the wire unless there's some space to put it in sight.
Cows get pretty smart about this, so if they have grazed corn before, you need to let them in with a belly full of hay so they don't get grain overload. Cows that haven't seen corn before aren't quite so bad.
There are 130 pairs in this picture. When they were done, the field was bare, right down to the ground. It only needed one pass with the cultivator in the spring.
Sorry the picture is so big. I resized it to half size in my computer, then resized it to 25% of original in Photobucket and it's still big!! :???: What am I missing here?
