【摘要】：正前言:為研究干燥黑水虻蟲粉替代育肥豬飼料中豆粕、魚粉等蛋白質(zhì)原料的可行性,以黑水虻干燥蟲粉為原料,選擇18頭30kg左右的"杜×長×大"三元雜交育肥豬,按試驗要求隨機分為3組(按照等能等氮配方設計,試驗Ⅰ組將飼料中豆粕等蛋白質(zhì)原料用25kg魚粉替代,試驗Ⅱ組將試驗組中的魚粉用25kg干燥黑水虻蟲粉替代,對照組飼喂基礎日糧),每組6個重復,每個重復1頭豬。正試期28d,計算各組育肥豬的平均日增質(zhì)量、平均日采食量和
[Abstract]:In order to study the feasibility of replacing soybean meal, fish meal and other protein raw materials in feed of fattening pigs by drying black water fly insect powder, 18 30kg 脳 long 脳 big three-way crossbred fattening pigs were selected with dry insect powder of black water gadfly as raw material. According to the requirements of the experiment, the rats were randomly divided into three groups (according to the design of iso-nitrogen formula, the protein raw materials such as soybean meal in feed were replaced by 25kg fish meal in group 鈪，
