Interaction of goats and grass/forb pastures in full sun and shade

摘要

Spanish X Boer does averaging 25 kg were evaluated to determine ADG and selectivity of 6 legumes, 1 non-leguminous forb, and 1 grass grown as treatments of full sun grass-only (FSG), full sun mix (FSM), and shaded mix (SM). The 1999--2000 rainfall over the trials was well below the 30-year averages. Goats in the FSM obtained the highest and the FSG goats the lowest ADG during both years. Grass percentage composition increased over time for all treatments in both years. Legume percentage composition decreased over time for both mixed treatments in both years. The FSM produced the highest DM yields in 1999, with the FSG recording the highest yields in 2000. CP concentrations decreased and ADF, cellulose, and lignin concentrations increased over time for all treatments.
