有机盐可以改善动物的生产性能，提高营养物质的利用效率，改善肠道菌群。研究了饲料中添加不同含量丁酸钠和丙酸钠对凡纳滨对虾生长的影响。总共评估了七种饮食：对照饮食（无补充剂）和钠盐、丙酸盐和丁酸盐各三种饮食，浓度分别为0.5%、1%和2%。我们使用了21个6000 L的储罐，其中储存了150只虾（2.53 +/-0.03 g）。虾饲料补充丙酸盐和丁酸盐，在所有浓度，增加了他们的最终重量。在饲料中添加2%丁酸盐可提高对虾的饲料效率、氮沉积率、蛋白质效率、成活率和产量。补充丁酸盐的虾也显示出较低的肠内弧菌计数。饲料中添加丁酸盐和丙酸盐的对虾也显示出较高的血清凝集效价。因此，可以得出结论，在不同膳食浓度下膳食补充丙酸盐和丁酸盐改变了肠道微生物群并改善了L.瓦纳梅。
Organic salts may improvement the animal performance, increasing the efficiency of nutrient utilization and modifying the intestinal microbiota. This study aimed to evaluate the effects of sodium butyrate and sodium propionate supplementation at different levels of dietary inclusions in the growth of Litopenaeus vannamei. In total, seven diets were evaluated: a control diet (without supplementation) and three diets from each sodium salt, propionate and butyrate, in concentrations of 0.5%, 1% and 2%. We used 21 tanks of 6000L stocked with 150 shrimps (2.53 +/- 0.03g). The shrimps fed diets supplemented with propionate and butyrate, in all concentrations, increased their final weight. The feed efficiency, nitrogen retention, protein efficiency rate, survival and yield of shrimps fed the diet containing 2% butyrate were higher in comparison with control treatment. The shrimps supplemented with butyrate also showed lower counts of Vibrio sp. in the intestine. The shrimps fed the diet supplemented with butyrate and propionate also showed higher values of serum agglutination titre. Thus, it is possible to conclude that dietary supplementation with propionate and butyrate in different dietary concentrations modify the intestinal microbiota and improves the growth of L. vannamei.
