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.
This study aimed to detect the relationship between some metabolic
indicators of energy with fertility results in the period: 8 weeks
before calving till 8 weeks after calving in dairy cows.
Forty eight dairy cows, 5-9 years old, were used to determine
their response for using of equine Chorionic Gonadotropine (eCG)
and Cloprostenol associated with PRID on post-partum anoestrus
treatment in order to increase the fertility.
