I am a small farmer( not for profit but raise my own beef and poultry) that treats my animals well. Nothing is more dangerous than a bottle fed calf. Cattle show" affection" with head butting and leaning. You do not want to be between a cow and a wall, never get into a position where you don't have an escape.
Cows can be trained,I object to the term taught. Cows know when it is milking time and head for the barn, they know their own stanchion,and all hell breaks loose when another gets confused and takes the wrong one.
Cattle trained for tillage require almost daily reinforcement of their skills,or they will be forgotten, no where close to the trainability of a horse.
When I open the gate and go into the pasture, the cows come running,not because of affection,but because of curiosity and the fact they have been trained that the presence of a tractor indicates food.
Yes Debbie I did miss the article, I clicked on the link and was brought to what appears to be an attorneys page soliciting clients for the settlement.
