You know that if you care for cows that you'll need to keep them healthy or treat them from time to time. So, you'll have to be able to handle them. There are many types of handling systems available, but, ultimately, cattle don't like to be individually handled and can become distressed in the process.
Cattle like to feel safe so that they can chew their cudd.
What stockmen want is for their cattle to feel safe enough whilst being handled to chew their cudd.
Dr. Don Finlay, a practising vet from Australia has the solution. He, and his team, have observed, studied and worked with cattle to develop a simple system to calm handled cattle down whilst they are being attended to by humans.
This is exactly what good stockmen want.
