The present invention relates to a method for producing a sulfur feed. A method of: grinding mineral sulfur； inputting the sulfur in a steamer and primarily steaming the sulfur by applying steam； drying the sulfur for 24 hours； applying steam containing acetic acid again to steam the sulfur for 4-5 hours； and drying the sulfur for 24 hours is repeated three times to perform detoxification. And then, the sulfur is ground into fine particles. Accordingly, 0.1-0.3 wt% of sulfur fine particles is mixed to an ingredient feed so a sulfur feed is produced.본 발명은 광물성 유황을 분쇄하여 찜통에 넣고 스팀을 가해 1차 증자한 후, 24시간 건조시키고 다시 초산이 함유된 스팀을 가해 4~5시간 증자하고 24시간 건조시키는 방법을 3회 반복하여 제독하고 미립자로 분쇄하여 단미 사료에 0.1~0.3중량% 혼합한 유황 사료의 제조방법이다.
