Woody plants constitute a vital food reserve for the herbivores inhabiting the Patagonian steppe. In a preliminary study, some of these plants showed a high content of ether extract (FAT). To determine whether the low availability of nitrogen in soils leads to low forage quality and whether a high FAT content correlates with a high amount of nutritive lipids, namely fatty acids (FA), chemical parameters of forage quality of aerial parts of thirteen woody plants from this steppe were analyzed. Plants showed moderate or low crude protein (CP) content, and, independently of the FAT content, all samples had approximately the same total content of FA (TFA), with an average of 1% of dry matter. The highest CP content was found in aerial parts of Atriplex lampa...
