Oregon Revised Statutes Animals § 604.035

(1) The brand recorded or renewed under ORS 604.027 is the exclusive property right of the holder thereof, and the holder has exclusive right to use the brand in accordance with its recordation. The holder may transfer the recorded brand by sale, assignment or otherwise and may bequeath the brand by will or subject to the laws of descent and distribution as personal property.

(2) Proof of a recorded brand is prima facie evidence of the ownership or right to possession of livestock upon which the brand is used in all civil or criminal actions and suits involving an issue of ownership or right to possession of such livestock. Parol evidence is inadmissible to prove a person is a holder of a recorded brand. Evidence of ownership or right to possession of livestock by Oregon brands thereon is inadmissible unless the brands are recorded, and a disputable presumption of ownership arising from possession, common reputation or the exercise of an act of ownership shall prevail.
