A stallion that was severely injured at Olds College when someone deliberately let it loose to battle other stallions for dominance is making a full recovery.

Staff and students at the agricultural college say someone tampered with the pens and let four stallions and two geldings out to battle for dominance.

The incident happened in September and one horse bled to death after being kicked repeatedly.

A second horse, named Mac, was seriously injured in the incident and suffered numerous cuts and bruises.

The 20-year-old stallion has been at the college for years and is surprising vets by his quick recovery.

“We call him the energizer bunny, he just keeps going and going. He is the best teaching stallion you could have because he loves his job and he just keeps working and working and nothing stops him,” said Dr. Marion Anderson.

Since the incident security at the school's corrals has been stepped up and the pens are now chained and locked.

A $4000 reward is being offered for information in the case.

So far no arrests have been made in the incident.
