| dc.description.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. The mean quantities of Azolla (g/m2) obtained from conventional and bioremediation methods were 137.5±3.15 and 124±2.07, respectively and the difference in yield was significant (P<0.01) between the methods. 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 dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fibre (CF), nitrogen free extract (NFE), total ash (TA), acid insoluble ash, calcium and phosphorous content of conventionally produced Azolla on DM basis was 89.85, 76.14, 21.10, 3.6, 14.60, 33.54, 23.21, 7.64, 2.49 and 0.26%, respectively and the same values for Azolla obtained with bioremediation was 89.79, 76.12, 20.71, 3.7, 14.54, 33.64, 24.24, 7.85, 2.52 and 0.29 %, respectively. The mean fortnightly feed intake (Kg) was 20.81±1.48, 20.74±1.46 and 20.73±1.47 for control, T1 and T2 groups, respectively which was significantly (P<0.01) higher in control group compared to Azolla supplemented groups, while the difference was not significant among T1 and T2 groups. The average daily gain (g/day) for control, T1 and T2 groups was 73.66±4.69, 72.54±2.45 and 73.2±3.35, respectively and the difference was not significant among the groups. The mean feed conversion ratio (FCR) for control, T1 and T2 group lambs was 18.83, 19.06 and 18.87, respectively. The cost per kg weight gain for C, T1 and T2 was 78.47, 73.05 and 69.20, respectively. The present study concluded that Azolla can be used for bioremediation of dairy farm liquid waste in an eco-friendly manner and the azolla obtained from bioremediation is as good as Azolla produced from conventional method and can be used as economic protein source in lambs. | en_US |
