An Evaluation of Replacing Soybean Meal with Proteolytic Soybean Meal in Low-Fish-Meal Diet on Growth Performance, Expression of Immune-Related Genes, and Resistance against Vibrio alginolyticus in White Shrimp (Litopenaeus vannamei).

ABSTRACT: A 56-day feeding trial was conducted to investigate the effects of dietary proteolytic soybean meal (PSM) on growth performance, immune-related genes, and resistance against Vibrio alginolyticus in Litopenaeus vannamei. Six dietary levels of PSM (0, 35, 45, 55, and 65 g/kg) were added to a basal diet. The results showed that juveniles fed more than 45 g/kg PSM exhibited significantly (P < 0.05) promoted growth performance compared to the control. Furthermore, all PSM supplemented treatments showed significantly better performances in terms of feed conversion ratio (FCR), the protein efficiency ratio (PER), and the protein deposition ratio (PDR). Corresponding to the performances on growth and nutrient utilization, a significantly higher protease activity in hepatopancr
