There really isn't much of an obvious difference, except Herefords are a horned breed and Polled Herefords are bred to be naturally polled or hornless. Some of the Hereford breeders will tell you that the horned Herefords have more depth and are a little larger than the polled Herefords, but when a novice looks at a horned Hereford and a polled Hereford side-by-side, he will see no other obvious differences.
Angus, Red Angus, Polled Shorthorn, Polled Hereford, Brangus, Red Brangus, Red Poll, are the breeds that I can think of that are born naturally polled.
In the United States a Polled Hereford strain was developed around 1900 by selecting naturally hornless registered Herefords. The number of Polled Herefords has increased rapidly; herds are found throughout the United States, including Hawaii, and the strain has been widely exported.
All of the lower 48 would produce Polled Herefords. It just takes a bit of looking and researching to find any breeders that do have such animals.
The same kind of horns that any other bovine (cow or bull) has. But if it's to describe the shape, they are short and curved, often made to curve down and towards the head of the animal to minimize risk of injuring other bulls and cows or the handlers.
The average birthweight of a Hereford calf is around 45 to 80 lbs, depending on the genetics influenced by the dam and sire of that calf. This is for both horned and polled cattle of this breed.
The term "polled" refers to cattle that naturally lack horns. In these animals, the genetic trait for hornlessness is inherited, meaning they do not develop horns as part of their anatomy. Polled cattle are often bred selectively for this trait, as it can reduce the risk of injury to other animals and handlers. This trait is common in several breeds, including the Polled Hereford and some strains of Angus.
He started developing Polled Herefords, which are a hornless mutation from Horned Hereford cattle.
Maybe not Champion Herefords, but it does say in several articles that he raised (and probably still does) Polled Herefords on his ranch in Ontario.
