Hi Jessica! We breed and raise registered Texas Longhorns. According to the Texas Longhorn Breeders Association of America, there are somewhere in the vicinity of 250,000 Texas Longhorns registered. There were an estimated 10 million longhorns that trailed to Northern markets between 1866 and 1895. Two sites for more info: <A HREF="http://www.tlbaa.com" TARGET="_blank">www.tlbaa.com</A> and <A HREF="http://www.itla.com" TARGET="_blank">www.itla.com</A> these are the 2 principal USA registries of Texas Longhorns. Good luck with your project!
