Costs were calculated with a combination of accounting records and "ingredients" estimates using unit costs and quantities of inputs [ 36].
An ABC methodology was applied to all costs in this analysis, including both accounting costs and ingredients estimates; this methodology was used to achieve multiple analytical goals.
The ABC methodology was applied to all costs, including both accounting costs and ingredients estimates, and costs to both institutions and communities.
Other European countries that cannot calculate the nUDD due to lack of detailed data, approximate the number of applications by the Defined Animal Daily Doses ADD which is calculated by the amount of active ingredients, estimated standard live weights and recommended dosages [ 10, 11, 21].
Total cost was estimated using a combination of accounting data (for ACF costs) and ingredient cost estimates (for costs to partner organizations and participating households).
See the Additional file 1 for further details on costing assumptions and ingredient cost estimates.
All accounting data and ingredient cost estimates from 2008 and 2009 were adjusted for inflation using a Consumer Price Index [ 25], and all cost data are presented in 2010 Euros using the December 2010 exchange rate (1 USD = 0.75455 EUR) [ 26].
The energy digestibility of the ingredients tested, estimated by substitution, were 0.479 ±0.0400, SEM) and 0.327 ±0.0499) for COC and PDOC, respectively.
Average aerial application rates for these three active ingredients were estimated at 3.3 kg ha-1, 7.0 kg ha-1 and 1.8 kg ha-1, respectively.
