The aim of the study was to examine the effect of livestock production on the economic efficiency of investments in irrigation projects. The study was based on a model focused on field crop/livestock production using the data of crop yields in field crop production with or without irrigation, financial results of cattle fattening and milk production and the input and output price relationship.

Marketability of livestock production was analyzed based on the marketability of both pork, beef, sheep and poultry and eggs and cow's milk. The sequential order of the Vojvodina municipalities according to the observed denominators is not identical. But, Spearman's coefficient of correlation points to a statistically very high degree of accordance between the rank-list of marketability of pork and the rank-lists of marketability of beef, poultry and milk as well as the rank-list of poultry and sequential classification of sheep meat and eggs, beef and milk.
