In addition to raising quarter horses, Spring Canyon Ranch is also a small cow-calf operation.  Forty pure-bred Limousin mother cows are bred with registered Angus bulls.  Calving generally takes place from March to May.   In early summer, the calves are branded, castrated and vaccinated with Ultrabac 8 and Virashield 6 + VL5.   We do not use any hormones and only use antibiotics when necessary.   After coming off high-altitude pasture, the calves receive pre-weaning booster shots in October or November.
