A study was carried out to determine the effect of dietary supplementation of azolla grown on dairy farm liquid waste (non conventionally produced) compared to conventionally produced azolla on growth performance of lambs and also to find out its suitability for feeding small ruminants. Eighteen Nellore lambs of about 3-4 months age, having uniform body weights (13-14 kg) were selected and randomly divided into 3 groups of 6 lambs each in a completely randomized design. Control (C) group was fed with conventional diet without azolla, T1 and T2 groups were fed with diets in which 10% protein in the concentrate feed replaced with azolla produced by conventional and non conventional methods, respectively. The experimental diets were offered to the lambs for a period of 90 days. The average daily gain (g/day) was 73.66 ± 4.69, 72.54 ± 2.45 and 73.2 ± 3.35, and mean feed conversion ratio (FCR) was 18.83, 19.06 and 18.87 for C, T1, T2 groups, respectively. The cost per kg weight gain for C, T1, T2 groups was Rs 78.47, 73.05 and 69.20, respectively. The present study revealed that economic growth rates in lambs can be achieved by replacement of conventional protein with azolla. Further azolla obtained from dairy farm liquid waste can safely include in the diets of lambs which is economical compared to conventional azolla.
