本研究探討四種添加不同油脂含量的飼料，對經切除單眼柄之白蝦母蝦的催熟產卵及活存之影響。試驗飼料以魚粉及烏賊粉為蛋白質來源，並分別添加0%、1%、3%、5% 等不同油脂含量 (鱈魚肝油：玉米油=2：1)，經過30天試驗結果顯示，以飼料中添加1% 油脂組 (粗脂質11.4%，粗蛋白質52.7%，蛋白質和能量的比值105 mg protein/kcal) 之效果最佳，其母蝦無論在成熟率、產卵率、活存率及產卵數均優於其他三組。添加3% 及 5% 之油脂組反而比不添加者之效果差。

This study was conducted to evaluate the effect of artificial diets containing different lipid levels on ovarian maturation, spawning conditions, and survival of unilateral eyestalk-ablated female broodstock of Litopenaeus vannamei. Diets with 4 lipid levels of 0%, 1%, 3%, and 5% were used in this study. The ratio of cod liver oil to corn oil as the lipid source was 2:1. The protein sources were fishmeal and squid meal. In terms of the maturation rate, number of eggs spent, spawning rate, and survival, the best results were obtained in the group of females fed a diet containing 1% lipids (11.4% crude lipids, 52.74% crude protein, and 105 mg protein/kcal P/E ratio), while worse results were obtained in groups fed diets containing 3% or 5% lipids.
