Personal & environmental health issues are being raised by these programs. Kudos.
"1,000 lb cow weaning a 550 lb calf will need 13 AUM's to sustain the grazing system
13 AUM time 780 lb/AUM equals 10,140 lb of forage, let's estimate 35% harvest efficiency of the forage so the cow will need 10,140 / .35 = 28,971 lb of forage.
If your pasture can produce 3 tons of forage/acre (6,000 lb/acre), then 28,971/6000=4.82 acres/cow
Cross-fencing, supplemental feeding, winter hay, silage, etc. will adjust the number of acres."
