Goats naturally prefer a high proportion of browse in their diets. Therefore, research was initiated to investigate various silvo-pastoral production systems. In May 1997, six Paulownia treatments were planted in a randomized complete block experiment with six replications. Trees were between 6 and 12 cm in height at planting. Treatments included: P. fortunei seedlings, P. tomentosa seedlings, P. elongata seedlings, and three P. elongata clones. Each 4-m wide plot contained a single row of 12 trees with an intra-row spacing of 1 m. Leaf samples were analyzed from all six replications to determine mineral concentration in October 1997, and June and August 1998. Ca and P concentrations varied widely, and the Ca:P ratio exceeded the desired 2:1 with a range from 2.7:1 to 10.1:1. In October 1997, concentrations of Ca were similar in leaf laminae and petioles (1.26%), whereas P concentrations were twice as high in laminae (0.19%) as in petioles (0.09%). In October 1997, laminae from seedlings contained greater concentrations of Ca, Fe, and Zn than did laminae from clones, whereas the opposite was true for every element, with the exception of Fe, in June 1998. By August 1998, these differences had disappeared. Regardless of sampling date and leaf part, concentrations of Ca, Mg, K, Fe, Mn and Zn were sufficient to fulfill goat nutritional requirements, whereas P concentrations were too low. Goats readily browsed Paulownia laminae and no clear preference trends were observed between treatments. MenosGoats naturally prefer a high proportion of browse in their diets.
