ThesisItem Open Access STUDIES ON THE EFFECT OF GINGER, GARLIC AND FENUGREEK POWDER SUPPLEMENTED DIETS ON GROWTH AND SURVIVAL OF PACIFIC WHITE LEG SHRIMP, LITOPENAEUS VANNAMEI(SRI VENKATESWARA VETERINARY UNIVERSITY, TIRUPATI - 517 502, ANDHRA PRADESH (INDIA), 2018-08) MAHESH KUMAR, R; CHANDRASEKHARA RAO, A (MAJOR); CHAMUNDESWARI DEVI, B; MADHAVI, KThe present study : “Studies on the effect of ginger, garlic and fenugreek powder supplementation diets on the growth and survival of pacific white shrimp, Litopenaeus vannamei’’ was conducted in the Wet Laboratory of the Department of Aquaculture, College of Fishery Science, Sri Venkateswara Veterinary University, Muthukur. L. vannamei was fed with three different herbal powder of ginger , garlic and fenugreek of varying levels of 1%, 2.5%, 5%, 2%, 4%, 6%, 0.5%, 1% and 1.5% of concentrations respectively to assess the optimal growth promoting potential and survival rate. The feeding trial was continued for 63 days with triplicates in each treatment. The growth parameters (ABW, weight gain, SGR) feed efficiency parameters (FCR) and survival rate were significantly (P ginger > fenugreek > control. It was found that GP 4% supplementation in the diet was optimal level of inclusion in garlic supplementation for L. vannamei culture. The diet supplemented with GP 4% fed L. vannamei was showed best FCR with higher significance (P <0.01) compared to other treatments. Survival rate of the L. vannamei fed diets containing garlic powder were significantly (P <0.01) higher in GP 6% (91.6%) compared to control (58%). Similar trend of elevated survival rates was noticed in L. vannamei at ZP 2.5 (91.3%) and FP 1.5% (83.3%) compared to control. The growth promoting ability of herbs with varying concentrations higher in GP 4% followed by ZP 2.5% and FP 1% supplemented in L. vannamei diets.
