Polled cattle are those that are born without any buds that grow into horns. Instead they have in the middle of the top of their heads a knobby area that is called a poll, thus the reason that hornless cattle are called "polled." Polled is a genetic trait that is used in a lot of cattle today, and is a trait to be taken advantage of when the offspring has a horned sire or dam.
Bovine refers to a cow. I'm not sure what they mean by half cow.

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.
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.
The past tense of "poll" is "polled."
