Abstract
Probiotics represent a group of useful bacteria that provides a wide range of benefits. These valuable bacteria produce defense against various infections including bacteria and viruses and establish healthy homeostasis with host. Recent findings have also demonstrated that probiotics help in regulation of several biochemical parameters including carbohydrate utilization, lipid profile and protein metabolism. The selected probiotics also aid in absorption of several vitamins and vital mineral elements. Shrimps farming were growing aquaculture worldwide and emerged as an alternative source of food for humanity. The commercial shrimp farming acquires several technological inputs to ensure quality and yield. On the contrary, there are several limitations associated with shrimps farming where infection and associated diseases to growing shrimps is major one. Traditionally, chemical-based antimicrobial and antibiotic agents remain a cheap alternate to tackle such challenges. The use of chemical-based antimicrobials and antibiotic agents indeed harmful to the environment but also affect quality of growing shrimps. Probiotics gained tremendous success in aquaculture not only to protect against various infections but also in improving growth of shrimps. Here, in the present study we aimed to study effect of probiotics on biochemical profile of growing shrimps. Further, use of probiotics on the immune system of growing shrimps was also investigated. Here, in the present study Giant tiger prawn Penaeus monodon was used as model shrimp to study effect of various probiotics on growth profile. Shrimps were fed with the Lactobacillus lactis AR21 as probiotic. The effect of probiotics on biochemical and immune parameters was analyzed in time-dependent manner. The result shows that probiotics not only provide protection against invading pathogens but also improve immunity of growing shrimps.
