Nineteenth-century agriculture in Jettenbach was characterized by many small farms. The farmers with bigger farms had horses, and sometimes oxen as draught animals. On smaller farms, the cow was used as a draught animal. From this need arose the almost exclusive use of the Glan-Donnersberg breed of cattle. It dominated in Jettenbach even into the 1960s. Most farms did cropraising and livestock husbandry. Pig farming was rather rare, and sheep were only raised until about the turn of the 19th century. Specialized crops are no longer raised in Jettenbach, although the village is said to have been a main growing centre for rapeseed in the "Landcommissariat" of Kusel in the years after 1820 (4 226 hl in 1826). About 1870, herb growing, particularly for the seed, was important in the village. Among the herbs then grown were hops, for the brewery that was then found in Jettenbach. Winegrowing may have been practised here in the Middle Ages, bearing witness to which are certain local cadastral toponyms. Between 1870 and 1900 there was once again a vineyard (1 000 m2) in the village. There was also fruitgrowing in a meadow orchard.
