A 30-day study was conducted to evaluate effects of dietary soy lecithin (SL) on growth, reproductive performance and health indices in white-leg shrimp (Litopenaeus vannamei) brooders (28.6 ± 0.2 g).Four different SL levels including 0 (control), 2, 4 and 6% was included to a basal diat contained Ca. 50% protein and 10% lipid. At the end of feeding trial, shrimp brooders fed 4% SL had the highest growth performance and the lowest latency period compared to the other experimental groups. Eggs diemater in brooders fed diets contained 4 and 6 % SL was higher than the other groups.
