The study aimed to construct a knowledge test to measure the knowledge of farmers about existing opportunities of rearing buffaloes as fattening animals. A total of 46 items were initially constructed to promote thinking rather than root memorization and differentiate the well-informed dairy farmers from the less informed ones. Then, the scores from sample respondents were subjected to item analysis, comprising of item difficulty index and item discrimination index. The final scale consisted of 15 items with a difficulty index ranging from 30-80 and a discrimination index ranging from 0.30 to 0.55. The reliability of the knowledge test developed was tested by split half and test-retest method. The coefficient of correlation values in split half and test-retest methods were 0.70 and 0.64, respectively, which were found to be significant at 1 percent level. It was found that the knowledge test constructed was highly stable, reliable and dependable for measurement.
