Greenhouse Gas Emissions and Crossbred Cow Milk Production in a Silvopastoral System in Tropical Mexico.

In Mexico, pasture degradation is associated with extensive pastures; additionally, under these conditions, livestock activities contribute considerably to greenhouse gas (GHG) emissions. Among the options to improve grazing systems and reduce GHG emissions, silvopastoral systems (SPS) have been recommended. The objectives of this work were to quantify the N outflow in a soil-plant-animal interface, as well as the CH emissions and milk production in an SPS with woody legumes () that is associated with stargrass ().

Increase in Milk Yield from Cows through Improvement of Forage Production Using the N-Fixing Legume in a Silvopastoral System.

The objective was to evaluate milk production, N-fixation and N transfer, forage yield and composition (under two cutting intervals) in a silvopastoral system (SPS) with and -monoculture (MMM) with crossbred cows in a completely randomized design. Forage yield in the SPS was 6490 and 6907 kg DM ha for cutting intervals (CI) of 35 and 50 days. Forage yield for the MMM was 7284 and 10,843 kg DM ha, and forage crude protein (CP) was 29.
