The aim of this study was to use the profit function
model to estimate factors affecting profit per kg egg in
laying period. To achieve the objective of the study,
data from 40 operating and randomly selected egg
production enterprises was collected. Data regarding a
whole production period were obtained directly from
the producers during April to mid August 2010. Semi
structured interviews were conducted with a pre-tested
questionnaire. Entrepreneurs themselves were involved
in providing data so the reliability and accuracy of data
were encouraging. The data obtained via interview
surveys were processed to calculate profit per kg egg
and other relevant information for inclusion in a profit
function model. 15 eggs are registered to be 1 kg in the
study. Table 3 shows the items of costs and income
calculated to obtain profits.
