Abstract

Livestock moved often from one area to another are required to forage on plants of different life form. The degree to which experience foraging on one plant form affects foraging performance on another plant form is unknown. We compared the foraging skills of grass- vs. shrub-experienced lambs on monocultures of mature crested wheatgrass (Agropyron cristatum × Agropyron desertorum) and the shrub serviceberry (Amelanchier alnifolia). Grass-experienced lambs were more successful (PPP>0.05), more successful than grass-experienced lambs at prehending (93% vs. 86% success) and ingesting (5.0 vs. 4.5 g min−1) shrub. Shrub-experienced lambs had a higher (PP>0.05). We conclude that the skills acquired by foraging on one plant form are to an important extent specific to that plant form. However, grass-experienced lambs foraging on shrubs were aided more than shrub-experienced lambs foraging on grass by their respective experiences.
