INCLUSION EFFECT OF NUCLEOTIDE ON GROWTH AND PROTEIN RETENTION IN PACIFIC WHITE SHRIMP Litopenaeus vannamei

Abstract

The growth of aquaculture in the world is expected to continue to increase. Intensification of vanamei shrimp farming is one of the best possibilities to increase aquaculture production while taking into account the limiting factors. Limited supply, price, and environmental factors are issues in meeting the needs of fish meals in feed. This study aimed to evaluate the effectiveness of nucleotides (NT, Nucleoforce Aqua™, Bioiberica, SAU, Spain) as feed additives produced commercially in optimizing feed formulations from plant-based ingredients in the aquaculture of white shrimp (Litopenaeus vannamei). A 60-day growth trial was conducted to evaluate five treatments: Basal-1 with 10% fish meal; Basalt-2 with 6% fish meal; Diet-1: 10% fish meal+0.1% NT; Diet-2: 8% fish meal+0.1% NT and Diet-3: 6% fishmeal+0.1% NT. As a feed additive produced commercially in optimizing feed formulations from vegetable ingredients in the aquaculture of vannamei shrimp Litopenaeus vannamei, the concentration of 0.1% nucleotide formulation has been able to provide good results. The growth performance of the tested shrimp was significantly related to the parameters of increasing biomass, final weight (FBW), feed conversion (FCR), feed protein retention, and average daily growth (ADG) (p<0.05) and TGC. The best results is Diet-1 (10% FMNT treatment) with the best protein content of 37.06% ± 0.15, showed the best performance of growth parameters (ADG, FBW, SR, TGC, PER, and RP) and lowest FCR. The addition of 0.1% nucleotide proves that the functional and nutritional properties of NT have many advantages in increasing the growth rate and more efficient protein absorption. Therefore, 0.1% NT can be recommended as a supplement in shrimp feed. So this study explains that the nucleotide addition of 0.1% in the feed provides an affirmative effect on growth performance and protein content parameters of the whole body of white vanamei shrimp.
