PURPOSE: A manufacturing method of fermented liquid feed utilizing green tea and useful microorganisms to substitute antibiotics, and adding honey to obtain higher quality beef is provided. CONSTITUTION: A manufacturing method of fermented liquid feed comprises: a steam treatment process to sterilize and gelatinize green tea leaves and barley-mixed barley bran by steam-heating in a steam heater for 1 hour 20 minutes to 2 hours； a pulverization process to pulverize the steam-heated green tea leaves and barley-mixed barley bran； a mixing process to mix 800-1,200L of water, lactobacillus, aspergillus, and a yeast agent to 45-55kg of sterilized and gelatinized barley-mixed barley bran； a fermentation process to ferment the mixture of live bacteria and the processed green tea powder and barley-mixed barley bran； and a dilution process to dilute fermented liquid with 2.0-2.5 times of water. In the mixing process, 1 weight% of Lactobacillus casei, 2 weight% of Aspergillus oryzae, 2 weight% of Crevisiae yeast, 2 weight% of Coreanus yeast, 2 weight% of Sake yeast, and 2 weight% of Awamon yeast is mixed with 1,000L of mixed raw material containing the sterilized and gelatinized green tea leaves and barley bran. In the mixing process, 4-5kg of honey is also added. The fermentation process is conducted in a separate fermenter at 25-39 deg. C for 6 days.본 발명은 사료 내 첨가된 항생제를 대체할 수 있도록 녹차와 유용미생물을 활용하고, 고품질의 육질을 얻기 위해 벌꿀을 혼합한 벌꿀 및 녹차가 혼합된 액상발효사료의 제조방법에 관한 것으로서, 녹차잎을 보리혼합 맥강을 스팀가열로의 내부에서 1시간 20분 내지 2시간동안 스팀 가열하여 살균 및 호화처리하는 증기처리공정과； 증기처리된 녹차잎과 보리혼합 맥강을 분쇄하는 분쇄공정과； 살균 및 호화처리된 보리혼합 맥강 45~55㎏에, 물 800 ~ 1200ℓ와 유산균 및 누룩곰팡이, 효모제를 혼합하는 혼합공정과； 생균과 가공된 녹차분말 및 보리혼합 맥강의 혼합물을 발효시키는 발효공정과； 발효공정에서 얻어진 액상의 발효액을 2.0~2.5배의 물에 희석하는 희석공정으로 되어 완성되어 지는 것을 특징으로 한다.
