Productivity of dairy animals largely depends on efficient feeding management. Balanced and proper feeding results in better utilization of nutrients and optimum milk production. Farmers feed their buffaloes with roughages and concentrate (cottonseed cake) without any consideration about quality and quantity of feed in Bundi District of Rajasthan. Traditional supplements based on cottonseed cake are expensive and cannot fulfill the required nutrients to animals. There is ample scope for improving the productivity of livestock by better balancing of nutrients and optimizing the utilization of feed resources. Azolla has been reported as potential feed supplement for dairy animals, which have rich nutrient and mineral profile. An On Farm Trail was conducted to study the effect of Azolla as feed supplement in buffaloes. The control group (C) farmers practice was fed wheat straw and green fodder with cottonseed cake. In the treatment group (T) 1.5 kg fresh azolla/animal/day was supplemented over conventional ration. The average daily milk yield was significantly higher in treatment group.
