Evaluation of new non-genetically modified soybean varieties as ingredients in practical diets for Litopenaeus vannamei

摘要: Abstract Twelve ingredients obtained from new, non-genetically modified soybean cultivars as well commercially available sources of meal (SBM) were evaluated in practical feed formulations for the Pacific white shrimp, Litopenaeus vannamei , using both digestibility and growth trials. Apparent coefficients energy (ADE) protein (ADP) determined chromic oxide inert marker 70:30 replacement technique. Digestibility ADE ADP ranged 76.6 to 91.3% 93.6 99.8%, respectively. In general, two distinct groups high moderate values observed. A separate 8-week trial was conducted evaluate selected SBMs six replicate tanks per dietary treatment (10 shrimp tank, initial weight 0.52 ± 0.04 g). An SBM-based reference diet formulated commercial SBM (45.3), which then completely replaced on iso-nitrogenous basis with other experimental SBMs. Significant differences ( P  ≤ 0.05) observed performance but not survival. trends similar those trial. Ingredients (I)-16, I-17, I-18, I-19 demonstrate relatively higher terms supporting good growth. Results indicate that genetic selection nutritional characteristics has potential increase feeds. Statement relevance This study provides useful important information 12 varieties support aquaculture industry development.
