Applying 100 kg N/ha to 20 % of the cow-calf farm, either in autumn or spring, enabled a stocking rate of 1.1 head/ha (a 22 % increase), sustaining gross margins even during dry seasons. …”

Economic analysis of trypanocide use in villages under risk of drug resistance in West Africa. por Affognon, Hippolyte D.

“…The results suggest that treating the damage control inputs such as trypanocides in cattle production, as yieldincreasing inputs in the conventional framework is likely to generate misleading results. The marginal value products of isometamidium in all epidemiological conditions, and the marginal value product of diminazene in high-prevalence-high-resistance conditions, reveal an underuse of trypanocidal drugs. …”
