Dairy bulls are usually raised "by hand".
They then grow up with the idea that humans are part of their herd.
This disrupts their "natural" herding instincts and therefore often causes confused behavior.
This can contribute to bulls reacting more aggressively as they age.
In doing so, bulls sometimes literally challenge people to rank with them.
A bull can never be trusted, but the risk of attack can be reduced through proper handling and education.
EDUCATION STARTS AT THE BULL CALF
Cattle are herd animals. Healthy calves can be placed in a group pen early, (but not later than after weaning, at six to eight weeks).
Often there are no other bull calves of the same age available on the dairy farm. In that case, it is no problem to place the young bull calf with a group of slightly older, heavier bull calves. If these are not available either, he may feel free to grow up for a few months among a group of slightly older steers or heifer calves. That' s always better for his education than individual housing.
If the bull calf has been among a group of young heifers, it is always advisable to bring the heifers in heat afterwards (in consultation with your veterinarian). To prevent unwanted pregnancies!
Even better, (and often easier), is to let a bull calf suckle at a cow.
Not always possible organizationally, but the most ideal solution.
Besides less work, the cow also gives the right education in terms of natural cow and herd behavior.
The bull calf will imbibe this behavior naturally.
This in turn results in more respect for humans and a lower risk of attacks towards humans.
The only condition is that humans treat cattle correctly and respect them with knowledge!
