Process for increasing the growth rate and enhancing the feed efficiency of meat producing livestock

摘要

Growth rate of meat-producing livestock is increased and feed efficiency enhanced by periodic injection of a substance having growth hormone releasing factor (GRF) activity. The livestock are injected at least twice daily during their growth period and the injections are substantially uniformly spaced with respect to time. The total amount of the GRF substance administered per day is substantially equivalent in GRF activity to between about 1 and 100 micrograms human GRF per kilogram body weight of the livestock per day, preferably 30-50 micrograms human GRF per kilogram body weight of the livestock per day.
