Investigation of livestock and poultry feed crops supply for animal protein supply adequacy in Iran

In this study, in order to investigate measures of feed crops supply during Iran fourth program of development, the Nerlove partial adjustment model and system equations estimated by seemingly unrelated regression method were applied to time-series data of 1989- 2004. Results showed that compensation of animal protein shortage require providing inputs and production factors, i.e. agricultural sector products, which should be prepared from internal production or import. Based on the results, current flow of import and production of these crops did not compensate shortage of animal protein at the end of the program, unless by applying mentioned approaches, increasing productivity, making use of modern production methods, employing experts and educated labors, etc. Yield of production would be increased and this gap would be filled.
