Steers, per se, lack the (ahem, equipment) capacity to impregnate cows. I think you mean your bull jumps my fence.
Also I believe it could be argued that a specially engineered bull would rise to the level of a "dangerous animal" (such as keeping an elephant or a lion) for purposes of trespass and liability. The owner of a genetically engineered, patent-encumbered, bull would know and have prior knowledge about the unique danger involved in having such an animal escape and be held especially liable.
