An experiment was conducted on ten crossbred cows (400±25 kg, 3rdto 4th lactation) for sixty days to study the effect of azolla supplementation on milk yield, composition and economics in crossbred cows during September- October 2016. The animals were randomly divided into two groups on the basis of average milk production (6.77+0.35 kg/day; n=5). Basal ration was same for both the groups except fresh azolla supplementation@ 500/g/day in treatment group. The results revealed significantly higher (P<0.05) mean milk yield in treatment group (8.30+0.41 kg/day) in comparison to control (7.17+0.53 kg/day). However no beneficial effect of azolla supplementation was observed in milk composition i.e. milk fat, milk protein and SNF, whereas, milk fat yield was found significantly higher (P<0.05) in treatment group (0.33kg/day) in comparison to control (0.28kg/day). Also, the benefit cost ratio was found higher in treatment group (1.01) than control (0.73). On the basis of results, it is concluded that azolla supplementation in feeding regimen of crossbred cows is beneficial which is evident by increased milk yield, milk fat yield and improved benefit cost ratio.
