Thanks everyone. My cows are a little on the large size. The mature cows range from maybe 1450 - 1800# (most are 1550-1650#). They range from 4.5 - 7-ish (most 5.5 - 6.5). I don't care what size they are or what color they are just so they are good. I like my cows easy keepers, structurally sound, big middled, fertile, structurally sound, good temperament, balanced, and, oh yeah, did I say I like them structurally sound???
I know some of you will "poo-poo" my comment about being easy keepers, but they are. My cows are expected to work for a living. 60 day spring & 60 day fall breeding, all AI again this year, on grass & hay - no grain to the COWS. I do grain my replacement heifers from weaning, through breeding until they are turned out on grass around May 1st. They get about 5# whole shell corn/hd/day.
Pastures: I am running around 32 pairs, 16 replacement heifers & 5 dry fall calvers on about 70 acres of paddocks. Mostly native grasses. I say native, but at some point they were planted, just none of them since about 1987. I spray weeds (thistle & burdock) and mow the weeds the cows don't eat. I also will mow the seed heads off like this year with all this rain, pastures got ahead of us quickly! We have Orchard Grass, Timothy, lots of different clover, some birds-foot trefoil, and probably others I didn't mention & don't know.
