Most studies evaluating the use of distiller's dried grains with solubles (DDGS) to partially replace the use of soybean meal (SBM) in diets of shrimp Litopenaeus vannamei have been carried out under laboratory conditions, which has significant differences in terms of environmental and culture conditions with the out-door commercial pond. This study aims to extrapolate the laboratory trials into the out-door pond condition in order to evaluate the feasibility of incorporating DDGS at various levels (D0 (0%), D5 (5%), D10 (10%), and D 15 (15%)) to replace the use of SBM for 90-day culture period on the growth, body composition, total hemocyte count, lysozyme activity, and organoleptic characteristics of the shrimp. Seven hundred twenty shrimp (mean initial weight 1.06 ± 0.01 g) were randomly distributed into each of 40 net pens (3 × 2 × 1 per net pen) with 10 replicates per dietary treatment. The results showed an enhancement in biomass, mean weight, and thermal growth coefficient of shrimp fed with 5 and 10% inclusion levels of DDGS. Significant reduction of FCR was also observed with the use of 5 and 10% DDGS to partially replace SBM. There were no severe changes in the total hemocyte count (THC), lysozyme activity, color, aroma, and flavor of the shrimp. However, the texture of shrimp was significantly better with the use of 10 and 15% DDGS in the diet. In summary, regarding all the factors, DDGS is a promising alternative ingredient to replace the use of SBM with 5 and 10% inclusion levels and could modulate better growth, quality, and maintain the health condition of shrimp cultured in out-door pond conditions.

池塘条件下饲养的太平洋白虾、凡纳滨对虾饲料中干酒糟及可溶物的评价

大多数评估在凡纳滨对虾饲料中使用干酒糟（DDGS）部分替代豆粕（SBM）的研究都是在实验室条件下进行的，在环境和养殖条件方面存在显着差异与室外商业池塘。本研究旨在将实验室试验外推到室外池塘条件，以评估加入不同水平的 DDGS（D0 (0%)、D5 (5%)、D10 (10%) 和 D 15 ( 15%)) 替代 SBM 在 90 天的培养期内对虾的生长、身体成分、总血细胞计数、溶菌酶活性和感官特征的影响。720 只虾（平均初始重量 1.06 ± 0.01 g）被随机分配到 40 个网栏（每个网栏 3 × 2 × 1）中，每个饲料处理重复 10 个。结果显示，饲喂 5% 和 10% DDGS 的虾的生物量、平均重量和热生长系数均有所提高。使用 5% 和 10% DDGS 部分替代 SBM 也观察到 FCR 显着降低。虾的总血细胞计数（THC）、溶菌酶活性、颜色、香气和风味没有严重变化。然而，在饲料中使用 10% 和 15% DDGS 时，虾的质地明显更好。总之，综合考虑所有因素，DDGS 是一种很有前景的替代原料，可以替代 5% 和 10% 含量的 SBM，并且可以调节室外池塘条件下养殖的虾更好的生长、质量并保持其健康状况。
