Impact of frontline demonstrations on use of mineral mixture in milch animal ration of Dausa district (Rajasthan)

Front line demonstration is an effective technology transfer tool that bridges the milk production gaps. The front line demonstration trials on use of mineral mixture in milch animal ration were conducted in eight villages in Dausa Block, four villages in Lalsot Block, seven villages in Lawan Block, two villages in Sikarai Block and one village in Bandikui Block in Dausa District during the year 2013–14 to 2016–17. In this way total 113 FLDs were conducted by Krishi Vigyan Kendra, Dausa in 22 villages of Dausa district. Result indicated that the overall average percent increase in milk production was 10.04% after demonstration than the milk production before the demonstration during the year 2013–14 to 2016–17. Result also revealed that the Average milk production (Liter) per day/animal before demonstration ranged 5.524 to 6.500 liter per day/animal while after demonstration it varied from 6.065 to 7.140 liter per day/animal during consecutive four years. Extension yield gap varied from 0.541 to 0.652 liter/milch animal with an overall average of 0.608 liter/milch animal. It is also inferred that the demonstrated technology on use of mineral mixture in milch animal ration gave higher gross return, net return with higher additional benefit cost ratio as compared to farmer's practices (no use of mineral mixture in animal ration) during four consecutive years. The higher additional BC ratio indicated that the use of mineral mixture in animal ration technology is highly profitable.
