Eeficacy of probiotic supplemented diets on growth potentials and immune responses in white shrimp litopenaeus vannamei

Monitoring of growth performance studies were conducted with pacific white shrimp Litopenaeus vannamei after fed with three experimental diets i.e. commercial brand CP feed, feed formulated with plant based ingredients and feed formulated with animal based ingredients along with and without probiotics including soil, feed and water probiotics for a period of 120 days. Growth patterns of L. vannamei recorded highest growth potentials with probiotic supplemented commercial brand CP feed, followed by probiotic supplemented feed formulated with animal based ingredients and lastly feed formulated with plant based ingredients. The growth patterns were recorded for every 30 days and the culture operation was continued up to 120 days. Growth parameters including Weight gain (g), Specific growth rate (%), Average daily growth rates, Production rates, Feed conversion ratios were recorded in all the control and Experimental ponds. Haemolymph immune parameters including Total Haemocyte count, Hyaline cells, Semi-Granular cells, Granular Cells, Prophenol oxidase and Total protein contents were different experimental feeds with and without probiotic supplementation. The results obtained clearly demonstrate that due to supplementation of probiotics during culture operation reduced the pathogen load and lead to reduction in the breakdown of diseases and finally increased the productivity in terms of yield. Therefore, the probiotic supplementation will pave way for the triggering of growth rates significantly thereby increasing the productivity.
