Abstract
Organic manure utilization in aquaculture is a well-established and economically sound practice. In order to limit the adverse effects of chemical fertilizers and antibiotics in aquaculture, these are substituted with organic fertilizers and phytobiotics. Cow urine or gomutra is a liquid by product of metabolism in cows, while cow urine and cow dung have benefits as fertilizers. Cow urine acts as a very good liquid fertilizer and can also use directly in pond. Application of Gomutra in aquaculture has not been explored so far. Litopenaeus vannamei was selected in the present study due to high growth rate and production, commercial or marketing value Hence the present study has been aimed to know the effect of cow urine on the growth of Litopenaeus vannamei. The experiment was conducted for four weeks. Four groups were taken ie., sample A, sample B, sample C and control. In five litres of water 20 L.vannamei fingerlings were taken. (age one month). Sample A with 3%, sample B with 4%, sample C with 5% solution of cow urine was taken and control without cow urine. The feed is given same to the both sample and control. Then the growth parameters were calculated by using standard formulas for knowing the effect of cow urine on the growth of Litopenaeus vannamei finger lings. The survival rate is highest in Sample B (70%), indicating that the 4% cow urine treatment not only promotes significant growth but also improves shrimp survival. Samples A and C also show improved survival rates compared to the control, which remains at 50%. The results from the fourth week demonstrate that 4% cow urine is highly effective in promoting both weight gain and specific growth rates in Litopenaeus vannamei, while also ensuring high survival rates. Sample C (5% cow urine) also shows promising growth metrics, particularly in specific growth rate, suggesting potential benefits at varying concentrations. The data indicates that cow urine can be a valuable growth promoter in shrimp aquaculture, warranting further investigation into optimal concentrations for achieving maximum growth and health benefits.
