Grass-field Shorthorn Cattle(trademark registration No. 5270386 Fig.1)that possess a loss of functional myostatin result in the double-muscled phenotype with generalized hyperplasia and hypertrophy of the muscle. The cattle were developed form Japanese Shorthorn Cattle, and have superior carcass characteristics including a larger proportion of muscle (about 50% more muscle mass than normal-muscled cattle), lower proportions of fat and more tender meat (Fig. 2). The increased lean beef production shows that Grass-field Shorthorn Cattle are estimated to be a hopeful breed as meat cattle in days to come. Therefore, we are studying the further development of Grass-field Shorthorn Cattle and it’s whole mechanisms of increased muscle muss (Fig.3) as a new breed to reduce the environmental loading on beef production. The goal of our research is to establish innovative Green-Technology for sustainable and improving beef production of GSC and to utilize them for practical use.
