Polled livestock
(重定向自Polled cattle)


Polled livestock are livestock without horns in species which are normally horned. The term refers both to breeds or strains which are naturally polled through selective breeding and also to naturally horned animals which have been dehorned. Natural polling occurs in cattle, yaks, water buffalo and goats, and in these it affects both sexes equally; however in sheep, both sexes may be horned, both polled, or only the females polled.
