Experiments were carried out on 3 Lc lactis isolates, namely U.181, P.32 and W-331 as well as a mixture of these three isolates. Lc. lactis were applied orally through feed (pellets) at a dose of 108 cells/gram of feed. At 7 day intervals during the 35 days of the experiment, the weight of the shrimp was weighed and the hemolymph was taken to then calculate the total number of hemocytes and phagocytic activity. The experimental results showed that the average weight gain was between 106.8 ± 9.78%-138.2 ± 1.68%, while in controls it was 100.7 ± 3.72%. So the treatment effect of adding Lclactis on shrimp weight gain was between 6.0 ± 5.8% - 37.3 ± 3.4%.

So the effect size was treatment with the addition of Lc lactis to the total number of hemocytes was 20.1 ± 2.0% to 36.6 ± 9.6%. The average phagocytic activity in the treatment was 42.1 ± 0.8% - 48.3 ± 1.0% while in the control it was 30.4 ± 0.8%. So the magnitude of the treatment effect on phagocytic activity was between 38.1 ± 1.08% - 58.7 ± 1.05%. Based on this research, it can be concluded that Lc Lactis U.181, P.32 and W-331 can be developed as probiotics in shrimp cultivation either singly or in a mixture, because they are able to provide the effect of increasing body weight and increasing the performance of cellular immunity.

Percobaan dilakukan terhadap 3 isolat Lc lactis yaitu U.181, P.32 dan W-331 serta campuran dari ketiga isolat tersebut. Lc.

Pada interval waktu 7 hari selama 35 hari waktu percobaan dilakukan penimbangan berat udang dan pengambilan hemolimfe untuk selanjutnya dilakukan penghitungan jumlah total hemosit dan aktivitas fagositosis. Hasil percobaan menunjukkan rata-rata pertambahan berat antara 106,8 ± 9,78%-138,2±1,68%, sedangkan pada kontrol sebesar 100,7±3,72%.
