Abstract

Vibrio harveyi infection was an obstacle in shrimp culture. Meanwhile, the use of antibiotics in disease control was no longer effective, so the use of immunostimulants such as meniran leaves was the safest alternative. The purpose of this study was to determine the effect of adding different doses of meniran leaf extract (Phyllanthus niruri L.) to feed on the immune system of vannamei shrimp (Litopenaeus vannamei) which was challenged with Vibrio harveyi. This research was an experimental study using completely randomized design (CRD) consist of 5 treatments and 3 replications, namely, P1 (positive control): commercial feed + V. harveyi infection; P2 (negative control): commercial feed + 0.9% NaCl; P3: commercial feed + 0.5% Meniran leaf extract + V. harveyi infection; P4: commercial feed + 1% Meniran leaf extract + V. harveyi infection; and P5: commercial feed + 2% Meniran leaf extract + V. harveyi infection. The parameters observed were survival and immune response. Immune response analysis was carried out by counting hemocytes, phagocytic activation and total bacteria present in the shrimp intestines at the end of the study. The results of this study indicate that the addition of meniran leaf extract affects the immune system and the viability of vannamei shrimp. In conclusion, the addition of meniran extract to vannamei shrimp feed with a dose of 1% can improve the immune system and viability of vannamei shrimp against vibriosis.

Abstract

The problem arises in vanamei shrimp cultivation is the emergence of diseases, such as vibriosis caused by Vibrio parahaemolyticus. Jatropha leaf extract can be used as an immunostimulant because it contains bioactive compounds namely flavonoid, tannins, saponins, and alkaloids. This research used a completely randomized design (CRD) with 5 treatments with 3 replications. The treatments used were; P1 (feed without extract and bacterial infection); P2 (feed without extract and NaCl injection); P3 : Feed + 1% + bacterial infection; P4 : Feed + 2% extract from feed and bacterial infection, P5 : Feed + 3% extract of feed and bacterial infection. Based on the results of the study, the administration of Jatropha leaf extract was able to increase the highest SR value of P2 by 88.3%, the highest THC value of P5 at 24.46 x 106 cells/ml, DHC values ​​such as hyaline cells ranged from 36.67-71%, granular cells ranged from 17-38.57%, and semigranular cells ranged from 12-24.67%, the highest AF value in P5 was 77.25%, and the lowest TBC value was at P2 of 6 x 108 CFU/ml, the lowest TVC value was at P2 of 0.56 x 106 CFU/ml. The higher the dose of extract given, the higher the THC and AF, besides that, Jatropha leaves were also able to increase the SR value and suppress the growth of total bacteria and total Vibrio in shrimp intestines.
