RESUMEN
The study was undertaken in Rajasthan with the objective to examine the input-output relationships and assess the resource use efficiency in milk production. The study covered 60 dairy households. The results of Cobb-Douglas production function revealed that concentrate had positive and significant influence on returns from buffalo, crossbred cow and local cow milk. Green fodder and labour were also significantly influenced the returns from buffalo, crossbred and local cow. The results of resource use efficiency and marginal value productivity of inputs indicated that inputs were not optimally utilized by dairy households. The green fodder, dry fodder, concentrate and labour in buffalo, concentrate and labour crossbred cow milk production and green fodder in local cow milk production were found to be over utilized in study area resulting higher per litre cost of milk production on these species.
