Table 6. Use of a simulation model <strong>to</strong> compare the situation of dual-purpose<br />
systems in the dry tropics of Honduras versus the adoption of new<br />
forage germplasm <strong>to</strong> eliminate the purchase of feeds and <strong>to</strong><br />
improve production efficiency.<br />
