Abstract:
The present study was carried to test the Azolla (Azolla pinnata) as bioremediation agent for dairy farm liquid waste and to find out the effect of feeding Azolla obtained from bioremediation on growth performance of Nellore lambs. Eighteen Nellore lambs having uniform body weights were selected and randomly divided into 3 groups T0 (0% Azolla), T1 (10% Conventional Azolla), and T2 (10% Phytoremediation Azolla obtained from dairy farm liquid waste) of 6 lambs in each group in a completely randomized design. The experimental diets were offered to the lambs for a period of 90 days. Bioremediation of dairy farm liquid waste with Azolla decreased the pH from 7.96 to 7.38 and the colour of the liquid waste was changed from greyish black to brown colour. The turbidity, COD, BOD, Nitrogen and Phosphorous content was decreased to 48.14, 0.74, 0.43, 30.76 and 7.44%, respectively. The present study concluded that Azolla can be used for bioremediation of dairy farm liquid waste in an eco-friendly manner.
