Abstract
This paper was not presented at the conference.
This research aims to analyze the effect of probiotic and paraprobiotic L. paracasei treatment in different doses on growth, immunity response, and digestive enzymes of vannamei shrimps that had been infected with V. parahaemolyticus. The research design used six treatment groups with three repetitions in each group : (K-) group shrimps were fed without probiotics and paraprobiotics and injected with PBS, (K+) group shrimps were fed without probiotics and paraprobiotics and injected with V. parahaemolyticus, (PRI) group shrimps were fed with probiotics L. paracasei with 106 CFU/mL dose, (PRII) group shrimps were fed with probiotic L. paracasei with 109 CFU/ml dose, (PAI) group shrimps were fed with paraprobiotic L. paracasei with 106 CFU/mL dose, (PAII) group shrimps were fed with paraprobiotics L. paracasei 109 CFU/mL dose. PRI, PRII, PAI, and PAII group shrimps were all injected with V. parahaemolyticus. Vannamei shrimps weighed 3 grams were kept in a 15 L container at a density of 15 shrimps per container for 30 days. The shrimps were fed with supplemented feed four times a day. The maintenance of vannamei shrimps was continued after challenge tested with V. parahaemolyticus in the dose of 104 CFU/ml that was done until six days after injection. The results showed that either probiotic or paraprobiotic treatment through feeding can increase the growth, immunity response and digestive enzyme activity of vannamei shrimps that had been injected with V. parahaemolyticus at the best dose of 109 CFU/mL.
