I do cut my own hay but occasionally have had to buy some depending on the season. I think I have bought hay twice in the last fifteen years. I usually use poultry little for fertilizer but I have used commercial fertilizer on occasion.
  Some people do intensive grazing where pastures are rotated every few days. Although this does maximize pasture productivity, I have not done this as it is labor intensive and I have been concerned that the more crowded conditions for the animals may increase the chance of disease.
  I do not have any organic certifications.
  I do not using any hormonal growth stimulants.
  I have raised some of my own corn but depending on feed prices and pasture needs, I buy some corn as well.  I leave the calves on the mothers usually until about 7 months old. This depends some on the condition of the cow, weather stresses and so forth. I have adopted a program of weaning across a fence. This way it is less traumatic for the calf. The calf gets the emotional support of it's mother during the stressful weaning period. This has actually been shown to prevent weight loss associated with weaning. ]
  I try to control weeds with bush hogging but rarely have used commercial chemicals for weed control. I hav only sprayed a small portion of my property on two or three occasions in twenty years.
