     In order to provide high quality grass finished beef to the
     consumer, a joint endeavor between Pharo Cattle Compa-
     ny (a genetics provider specializing in low maintenance
     animals that fatten easily on grass) and Cactus Feeders                                                            Photos by Dale Strickler
     (one of the largest cattle finishing operations in the world)
     was undertaken to see if it was possible to economically
     produce a high quality, grass finished beef on forage alone
     and on a scale big enough to make it worth the while of a
     major packer.
     To make this happen, these companies sought the assis-
     tance of Green Cover Seed to develop a sequence of annual
     forages that could be grazed 12 months out of the year and
     provide adequate quality for the animals to fatten by 18
     months of age, a very tall order! The first year, a trial project
     was performed that consisted of a rotation of a spring plant-  High quality mixes with ryegrass, rye, and triticale are the base of the fall planted
