Abstract

This study was conducted to investigate the effects of dietary supplementation of a mixture of the glycerol esters of short-chain fatty acids (SCFAs) and medium-chain fatty acids (MCFAs) (short and medium chain fatty acid mixture, SMCFAM) on the growth performance, feed utilization efficiency, innate immunity, diet digestibility, and disease resistance of Pacific white shrimp, Litopenaeus vannamei. A basal diet was prepared (Con) and four other diets were prepared supplementing graded levels of SMCFAM at 0.35, 0.55, 0.70, and 1.10 g kg−1. Quadruplicate groups of shrimp were fed one of the diets for 53 days and then challenged with Vibrio harveyi. Growth performance was significantly improved by SMCFAM supplementation. Innate immunity and antioxidant capacity of shrimp were significantly increased by dietary SMCFAM. Diet digestibility was significantly improved in 0.35 and 0.70 groups than in Con and 1.10 groups. During the challenge test, shrimp fed SMCFAM supplemented diets had higher disease resistance to Vibrio harveyi compared to shrimp fed Con diet. Therefore, these results indicate that dietary supplementation of SMCFAM at low doses less than 1 g kg−1 can improve growth performance, innate immunity, antioxidant capacity, diet digestibility, and disease resistance of shrimp against V. harveyi.
