Many Pedigree Cattle Breed Societies administer a Semen Royalty Scheme whereby all pedigree calves registered with the respective Society generate a Semen Royalty fee if the calf is by a Royalty Sire. A fee, which is dependant on the bull, is payable by the person registering the calf and is thereafter credited to the owner of the Semen Royalty; or in some cases a Semen Royalty certificate is purchased from the Semen Royalty owner by the person wishing to register a calf. Semen Royalties do not apply to commercial/crossbred calves. Limousin & British Blue bulls with Semen Royalties are listed on the Royalty Sires side bar with the Semen Royalty fee in question displayed on the individual bull pages. Purchasers should nevertheless satisfy themselves beforehand as to the Semen Royalty status of a particular bull that they are considering purchasing.
