飼糧添加黑水虻（Hermetia illucens L.）預蛹粉末對5－9週齡仔豬生長之影響
Evaluation of black soldier fly (Hermetiaillucens L.) prepupa powder as a fishmeal substitute
摘要
本試驗目的為評估餵飼乾燥黑水虻預蛹粉末取代魚粉對仔豬生長之影響。先將試驗所需之黑水虻預蛹進行乾燥粉碎及營養分析再進行動物試驗。試驗動物為剛離乳之三品種〔L×Y×D〕雜交仔豬54頭（約35±2日齡），平均體重8.52±1.43kg，採隨機完全區集設計（randomized complete block design, RCBD）分配至3處理組，每組處理組3重複，每重複6頭，閹公豬及女豬各半。各試驗組飼糧以玉米－大豆粉為基礎飼糧原料，調配成等蛋白之飼糧（5－6週齡：CP≒24%；7－9週齡：CP≒20%）。並以乾燥黑水虻預蛹粉取代魚粉0%、50%及100%作為飼糧處理組，即分別含乾燥黑水虻預蛹粉0%（對照組）、2.5%及5%。試驗期間為期四週（即5－9週齡），於試驗期間飼料飲水皆採任飼。試驗結果顯示：（1）乾燥黑水虻預蛹粉營養分析之結果與前人文獻具有差異性，主因飼養基質及蟲齡不同所致；（2）動物試驗：就四週之試驗期間無論仔豬在平均日增重、平均日飼料採食量、飼料換肉率、下痢指數及存活率，乾燥黑水虻預蛹粉處理組與對照組間無顯著差異，然而在存活率，乾燥黑水虻預蛹粉處理組卻有較佳之趨勢。因此，乾燥黑水虻預蛹粉或可作為取代魚粉作為仔豬之動物性蛋白質來源選項之一，但若計入相關先期投入之乾燥及冷藏設備費用、生產黑水虻預蛹粉之水電費及人工費等，則每公斤的成本將會超過魚粉之價格，因此建議若要取代魚粉需以大規模量產攤提相關成本。

The aim of this study was to use drying black solider fly (BSF) prepupa powder to replace fish meal to feed piglets. Before the experiment, the BSF prepupa was dried and crushed into powder and was analyzed for comparison with other report data. In an animal experiment, the diets were adjusted for equal protein content, fifty-four piglet (half female and half male) were distributed using randomized complete block design into 3 treatment groups of both genders. Control diet was formulated with 5% fish meal, whereas fishmeal in the treatment groups was replaced with 0, 50, and 100 % drying BSF prepupa powder, respectively. The feeding span was about 4 weeks. The result showed that: (1) Different feeding matrix and larva age produced different nutrient-contents. (2) There was no significant difference in average daily gain (ADG), average daily feed intake (ADFI), feed conversion ratio (FCR), diarrhea index, and survivalrate for piglets fed with different diets. Although there was no significant difference between drying BSF prepupa powder treatment groups and control group in survival rate, the treatment groups performed had a better tendency in survival rate than the control group. However, considering the cost of drying and refrigeration, water and electricity bill and labor, the production of drying BSF prepupa powder was much more expensive than fish meal. Automation and large scale production might improve this situation.
