摘要: | 笛鯛屬中,體色紅色,符合中國人對食物喜好的赤鰭笛鯛,將可能成為台灣海水箱網養殖的主要魚種。本研究的主要目的, 在於探討赤鰭笛鯛飼料配方上,以醱酵豆粉取代部分魚粉之效果及其應用。 研究分為兩部分,第一部份在飼料中分別添加30%, 20%, 10%的醱酵豆粉及必需胺基酸,探討赤鰭笛鯛飼料中醱酵豆粉的最適添加量。第二部分則在添加20%醱酵豆粉的情況下,分別加入3.5%, 8.5%, 13.5%的脂肪,觀察赤鰭笛鯛對脂肪的利用性。 醱酵豆粉添加量達30%, 50天之後,赤鰭笛鯛的增重率明顯低於全魚粉的對照組,僅在醱酵豆粉含量為20%及 10%時,可與對照組相近,以Broken-line分析後,最適添加量為14.9%,若額外添加必需胺基酸,醱酵豆粉添加量可略為上升,利用Broken-line分析後,添加量上升為16.7%。 在飼養50天之後,隨著飼料中脂肪添加量的上升,赤鰭笛鯛的增重率也隨之增加,在飼料中脂肪含量達17.8%時,赤鰭笛鯛的增重率及飼料效率227%,0.75為最佳,較對照組各高出70%與0.22。 Among the genus of Lutjanus, the Red striped snapper (Lutjanus erythropterus) with red-colored body, is suitable for the taste of Chinese people. It is most likely developing as the main kind of cultured fish using the seawater net cage culture in Taiwan. The aim of this study is to evaluate the effect of that using fermented soybean meal instead of fish meal for feed of the Red striped snapper and to explore its possible application. This study is divided into two parts. One is that to add separately 30%, 20% and 10% of fermented soybean meal and essential amino acid into the feed to discuss the most suitable amount of fermented soybean meal in the feed of the Red striped snapper. The other is that in the case of fixed amount (20%) of fermented soybean meal, 3.5%, 8.5% and 13.5% of fish oil are added, respectively, into the feed to explore the utilization of lipid for the Red striped snapper. After 50 days with the adding amount of fermented soybean meal up to 30 %, the weight gain (%) of the Red striped snapper is distinctly lower than controled. In the cases that the adding amount of fermented soybean meal are 20% arid 10%, respectively, the weight gains are similar in between. According to the Broken-line analysis, the most suitable amount of fermented soybean meal added in the feed is 14.9%. If the extra amount of essential amino acid is added, the adding amount of fermented soybean meal in the feed is increasing up to 16.7% based on the Broken-line analysis. After 50 days of feeding, the weight gain of the Red striped snapper increases with increasing lipid amount added in their feed. When the adding amount of lipid in their feed is 17.8%, their weight gain and feed conversion rate are 227% and 0.75, which are the best and 70% and 0.22 higher than controled, respectively. |
