Abstract

Aquaculture growth is expected to continue to increase until it, intensification of vanamei shrimp culture is one of the best possibilities for increasing aquaculture production. 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 AquaTM, Bioiberica, SAU, Spain) as feed additives available commercially in optimizing feed formulations from plant-based ingredients in the production of Pacific white shrimp (Litopenaeus vannamei). A 60-day growth trial was conducted to evaluate five dietary treatments: Basal-1 with 10% fish meal; Basal-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. Results showed that the inclusion of 0.1% nucleotide into the diet formulation has been able to provide good results. Adding nucleotides provides better performance and significantly increases the final biomass, final individual body weight (FBW), feed conversion ratio (FCR), feed protein retention, and average daily growth (ADG) (P<0.05) and thermal growth coefficient (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 in protein absorption. Therefore, 0.1% NT can be recommended as a supplement in shrimp feed.

Abstract

Growth performance, survival rate, productivity, and carcass analysis were examined in the whole grow-out production system for Pacific white shrimp Litopenaeus vannamei fed four commercial diets over 15 weeks. Shrimp were held in twelve hapas nets with a size of 2 x 2 x 1 m and installed within the commercial ponds. The shrimp were stocked with the density of 100 shrimp m-2 per net in a completely randomized design (CRD). All feed used in this study was characterized with high protein levels within the range of 40 – 42% labeled as HP A and B; and medium protein levels (30 – 35%), labeled as MP A and B. Based on the proximate and nutritional profile analysis of the diet, the nutritional profile of HP B, MP A and MP B written on the feed bags showed an inconsistent results compared to the results of the test.  Shrimp fed the highest protein level had higher final body weight; feed conversion ratio, thermal growth coefficient, survival rate and average daily growth compared to MP B. Shrimp fed higher protein level also exhibited the lowest feed conversion ratio compared to the group of shrimp fed with medium protein. The results obtained in this study indicated that with small difference in growth rates, especially between HP groups compared with MP A, there is still a chance to re-formulate the diet to produce a cost-effective diet that still fulfill the specific nutrient requirement of the shrimp. Feed did not influence the nutritional deposition of the whole body of shrimp, but it seemed due to the inappropriate drying techniques Keywords: Protein level, growth, carcass, Litopenaeus vannamei, specific nutrient
