Interpretive Summary: The conversion of grasslands to shrublands in the western United States and in arid regions throughout the world is a serious concern to livestock producers and ecologists. This process of desertification not only reduces available forage for livestock and wildlife, but also leads to increased soil erosion and reduced biodiversity. These shrubs often contain chemicals that make them unpalatable to browsing animals. We have been conducting a long-term study on the impact of volatile plant chemicals such as terpenes on shrub consumption by livestock. Our previous work showed that for a common shrub in the northern Chihuahuan Desert …

Many secondary compounds are typically present in unpalatable shrubs on arid and semi-arid rangelands. However, the relationship between intake by livestock and concentration of individual chemicals has been examined for very few of these compounds. Four experiments were conducted to examine effects of individual volatile compounds on intake of alfalfa pellets by lambs. Forty-five lambs (9 lambs/treatment) were individually fed alfalfa pellets with eugenol, α-terpineol, terpin-4-ol, or methyl eugenol applied at one of five concentrations. Treatments were multiples (0, 0.5, 1, 2, and 10×) of the concentration (×) of each compound on the leaf surface of Flourensia cernua. Treatment solutions …
