Engineering Technology of White Shrimp (Litopenaeus vannamei) Intensive System Culture with the Suplementation of Phytase Enzyme in the Diet

Abstract

This study aims to examine the effect of phytase enzyme in the diet on digestibility of growth of white shrimp (Litopenaeus vannamei) raised in intensive system culture. Research on the suplementation of phytase enzymes in L. vannamei diet is very important to hydrolyze phytic acid in vegetable ingredients as a source of diet protein so as to increase the efficiency of diet utilization to support growth of vaname shrimp. The shrimp used in the research had average weight of 1,19±0,06 g/shrimp. The diet contained 38% of protein and 3200 Kcal DE/kg with various doses of phytase enzyme suplementation, namely: A (0 U/kg diet), B (500 U/kg diet), C (1000 U/kg diet) and D (1500 U/kg diet). Observed parameters were digestibility of phosphore (ADCF), disgetibility of protein (ADCP), efficiency of diet utilitzation (EFU), protein efficiency ratio (PER), diet convesion ratio (FCR) relative growth rate (RGR), and survival rate (SR). The suplementation of phytase enzyme in the diet significantly influenced (P<0.01) on ADCF, ADCP, EFU, PER, FCR, RGR; however, it did not significantly influence on SR of white shrimp. The best treatment result was the suplementation of 1000 U/kg diet phytase enzyme (treatment C). The optimum dose of phytase enzyme in the diet was 867, 920, 923, 915, 1000 and 1000 U/kg of diet respectively for ADCF, ADCP, EFU, PER, FCR, RGR. Based on those result the suplementation of phytase enzyme can increase the growth of white shrimp.

Meta-Analysis: The effectiveness of artificial diets to increase on survival rate of vannamei shrimp (Litopenaeus vannamei)

“…The keywords used by the researcher when searching the article are (1) The artificial diets for vannamei shrimp (2) The survival rate of vannamei shrimp. Next, analyze the data in the form of: (1) Labeling or numbering the article (2) Writing the correlation test value (r), and the number of research subjects (N), (3) calculating the value of effect size (ES) and standard error (SE), (4) perform data analysis assisted by JASP software (5) analyze the results found from articles that become data references (6) Draw conclusions and suggestions.…”

“…The production of low-quality fry will have an impact on the failure of shrimp rearing aquaculture in ponds. At the larval stage, shrimp have a very small mouth opening so that the selection of feed size is very important [2].…”

Hasil penjualan ikan sistem boster lebih tinggi dibandingkan dengan sistem konvensional, sedangkan keuntungan yang didapatkan pada sistem boster lebih tinggi hasilnya karena hasil panen yang diperoleh lebih tinggi.…”

The Chemical Quality of Maggot Flour Uses Sangrai Method Processing

“…There are many studies related to maggot which provide potential subtitution for a source of animal protein, namely fish meal (Rachmawati & Samidjan, 2013). This is because maggot flour has a relatively low price and has relatively high rough protein content (Kardana et al, 2012).…”
