The study has evaluated the performance of state level animal fairs in Rajasthan using information on arrival and sale of animals and revenue realisation for the period 1996-97 to 2010-11. It was found that on an average both arrival and sale of animals had declined during this period. Small ruminants are rarely brought to these fairs. Only about half of the animals brought are sold with sales to arrival ratio being higher for horses, cattle and buffalo. The major reasons for decline in the arrivals include ban on sale of male cattle below three years of age to buyers from other states, inadequate market infrastructure for humans as well as animals, and lack of facilities of feed and fodder supplies. There is also considerable variation in the arrivals and sales over time. The income from organisation of the fairs had grown faster than the expenditure. The study suggests the need to utilise the surplus for development of facilities in the fairs.
