海水繁養殖研究(2003~2006)-不同油脂含量對白蝦種蝦成長及活存率的影響
主題: 不同油脂含量對白蝦種蝦成長及活存率的影響
摘要:
本研究探討四種添加不同油脂的飼料,對飼育白蝦種蝦的成長及活存率的影響。實驗飼料以魚粉及烏賊粉做為蛋白質來源,並添加不同油脂含量(魚油:玉米油=2:1) 0%、1%、3%、5%的四種飼料進行試驗。實驗進行12週,以飼料中添加1%油脂其總油脂11.4%,粗蛋白質52.7%,總能量502.2 Kcal/100g,蛋白質和能量的比值105 mg protein/Kcal,在雌種蝦成長、活存、飼料轉換率及增重均比其他三組(0%、3%及5%)為佳, 且FCR及活存率與3%及5%處理組有顯著差異(P < 0.05)。飼料中油脂添加過量(3%及5%組)反而比不添加(0%組)效果差,所以飼料中過量之油質反而會造成種蝦成長、增重及活存率下降。

標題title(英): Lipid levels on the growth rate and survival rate of boodstock Litopenaeus vannamei
摘要abstract(英): It was conducted for this study how the diets of lipid levels effected on white shrimp broodstock’s growth and survival rate. There contained fish powder and squid powder in four treatment diets as their protein sources, and added diverse levels of lipid to them, 0%, 1%, 2%, and 4%, separately. The lipid source was 2 /1, fish oil to corn oil. After 12 weeks’ experiment, the diet with 1% lipid level, total lipid 11.4%, crude protein 52.7%, total energy 502.2Kcal/100g, the ratio of energy 105 mg protein/Kcal, had been proved the most helpful than the other three to female broodstock in the growth, survival rate, feed conversion ratio (FCR), and weight gain. Which broodstock was fed with the 1% was significantly higher than the 3% or 5% treatment in FCR and survival rate (P < 0.05). Meanwhile, the 0% was better than the 3% and the 5% in these respects. The study finds it obvious that diets with excessive lipid make broodstock get lower growth rate, weight gain, and survival rate.
