The present invention provides a method for manufacturing a pellet-type composition for preventing the coccidiosis symptom of cattle, comprising the steps of: premixing monensin sodium, which is a main material, salt (NaCl), sodium saccharine, propionic acid, and calcium carbonate, which are auxiliary materials, and certain amounts of wheat bran, rumen corn and under-grade wheat flour, which are forming agents adding moisture to the premix by a spray while mixing the premix with certain amounts of the forming agents, and mixing the premix with the remaining amounts of the forming agents again making pellets and cutting the pellets into a constant size by mixing the premix, which has been manufactured by mixing the main material, the auxiliary materials and the forming agents, with a water-soluble material, and molding the mixture by an extruder at temperatures of 45 to 50°C and drying, passing, through an iron-removing sorter, and packing the pellets. The purpose of the present invention is to prevent the coccidiosis symptom of cattle via the pellet-type composition, of which the main component is monensin sodium, to increase the feed efficiency of cattle, to facilitate the growth of cattle, to increase the weight gain of cattle and to increase the milk yield of dairy cattle.COPYRIGHT KIPO 2014본 발명은 주원료인 모넨신나트륨과 부재료인 소금(NaCl), 사카린(Sodium Saccharine), 프로피온산(Propionic acid), 탄산칼슘(Calcium Carbonate)와, 부형제인 소맥피(Wheat Bran), 루멘콘(Rumen corn) 및 등외분((等外小麥粉)의 일정량을 원부재료와 섞어 프리믹스(primix)하는 단계와, 이 프리믹스에 부형제의 일정량을 혼합하면서 스프레이로 수분을 첨가한 후, 부형제의 잔여량을 섞어 재차 혼합하는 단계와, 원부재료와 부형제가 혼합된 프리믹스에 수용성물질을 혼합하여 45℃∼50℃의 압출기로 성형하여 펠릿화한 후 일정한 크기로 절단하는 단계와, 건조하여제철선별기를 통과시킨후 포장하는 단계로 구성된다. 본 발명은 모넨신나트륨을 주성분으로 하는 소의 콕시듐증 예방, 소의 사료효율개선, 성장촉진, 증체량개선 및 젖소의 산유량을 증대시키는데 그 목적이 있다.
