A method of processing dead livestock includes (a) sterilizing, which sterilizes a dead livestock died of disease by use of a metal complex (b) mincing, which minces the dead livestock into shattered meat (c) heating, which pours the shattered meant into a heating-stirring machine and heats the shattered meat to a sterilizing temperature for a heating period, wherein a deodorizing agent is added for deodorizing the shattered meat (d) cooling, which cools the temperature within the heating-stirring machine to 30-45 degrees Celsius, adds a mixture including corn flour, yeast, and lactobacillus, mixes all the contents, and bags or barrels the contents into semi-finished goods and (e) fermenting, which puts the semi-finished goods in the room temperature and ferments the semi-finished goods for a period into a feed for insects.本發明提供一種病死畜禽之處理方法,其處理方法係為以下步驟(a) 消毒:將病死之畜禽先以一金屬錯合物進行消毒;(b) 絞碎:接著透過一絞碎機將病死之畜禽絞碎成一碎肉,並噴灑金屬錯合物進行滅菌;(c) 加熱:碎肉倒入一加熱攪拌機加熱一滅菌溫度,並經過一加熱時間,其中,於攪拌過程中,添加一臭味處理劑進行除臭;(d) 降溫:將加熱攪拌機降溫至30度至45度,並添加一玉米粉及一酵母菌乳酸菌混合物進行混合攪拌,其後裝袋或裝桶形成一半成品;以及(e) 發酵:半成品放置於一室內溫度儲放,並經過一發酵時間形成昆蟲飼料。S1‧‧‧消毒S2‧‧‧絞碎S3‧‧‧加熱S4‧‧‧降溫S5‧‧‧發酵
