This study was done on the records of 564 milk cows
during the period 2004-2007 .Those cows were dismissed
for many reasons and in different ages. The range of
dismissing age is between 3-6 years. The ratio of
dismissing of those cows was between
20-25% . The rate
of dismissing was high in the first lactation season . It
reached 27,43% for the years 2004-2005, and 24,45% for
the years 2006-2007. The highest percentage of dismissing
was in the first month of milk seasons .It reached 34,49%
in the years 2006-2007.
The study is based on the cost of milk and marketing margins in dairy
farms in Jordan and estimated cost function. This study is based on a cross
section data from 33 dairy farms. In the study it was determined that the cost of
raw milk production
in dairy farms is 0.43 JD/ Kg. and the most important cost
factors are feed cost, depreciation contributing 64%, 19%, respectively of total
production cost. It was found that marketing margins of milk were 77%,
econometric estimation of raw milk function using different forms showed that
the linear model is superior to the other forms. The elasticity of the estimated
cost function is found to be 0.20.
