In the price column, – means no price given as the profiles were not presented to the farmers since they were not selected by the orthogonal design. However WTP was calculated from the individual attribute WTPs since the attributes of the profiles were known. KSh is Kenya Shillings and 1 USD = KSh 70. Frequency of vaccination was per animal per year. GOK is Government of Kenya. Rank was for the vaccine and vaccination profile according to the amount of money the farmers were willing to pay.
