Reducing livestock abortions and calf mortality to improve food security and lower GHG emissions in Tanzania and Kenya por Slater, Annabel, Arndt, Claudia, Balcha, Endale

“…When this happens, higher livestock production will directly increase emissions of enteric methane, a potent greenhouse gas (GHG). However, this can be mitigated through measures that make the livestock sector more efficient by lowering mortality during pregnancy and mortality of calves. …”

An Overview of Dairy Cattle Models for Predicting Milk Production: Their Evolution, Evaluation, and Application for the Agricultural Model Intercomparison and Improvement Project (... por Tedeschi, L.O., Herrero, Mario, Thornton, Philip K.

“…The contemporary concern about anthropogenic release of greenhouse gas (GHG) into the environment and the contribution of livestock to this phenomenon have sparked animal scientists’ interest in predicting methane (CH4) emissions by ruminants. Focusing on milk production, we address six basic nutrition models or feeding standards (mostly empirical systems) and five complex nutrition models (mostly mechanistic systems), describe their key characteristics, and highlight their similarities and differences. …”

Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population por Dolk, Oscar

“…Increasing ammonia concentrations lead to a shift in the dominant pathways for methane production, from acetoclastic methanogens to syntrophic acetate-oxidizing bacteria, working with hydrogenotrophic methanogens. …”

Summary: Climate-Smart Agriculture in the 2017 SAN Sustainable Agriculture Standard por Rainforest Alliance

Elevation of condensed tannins in the leaves of Ta-MYB14-1 white clover (Trifolium repens L.) outcrossed with high anthocyanin lines por Roldan, M., Cousins, G., Fraser, K., Hancock, K., Collette, V., Demmer, J., Derek, R.W., Caradus, J., Jones, Christopher S., Voisey, C.

“…Condensed tannins (CT) are highly desirable in forage as they sequester dietary protein and reduce bloat and methane emissions in ruminants. However, the widely used forage legume white clover (Trifolium repens) only produces CTs in flowers and trichomes and at levels too low to achieve therapeutic effects. …”

Climate-Smart Livestock Interventions in West Africa: A Review por Amole, Tunde A., Ayantunde, Augustine A.

“…Of this, about one third is reported to be due to land use change associated with livestock production, another one third is nitrous oxide from manure and slurry management, and roughly 25% is attributed to methane emissions from ruminant digestion. Recent analysis suggests that developing world regions contribute about two thirds of the global emissions from ruminants, with sub- Saharan Africa a global hotspot for emissions intensities, largely due to low animal productivity, poor animal health and low quality feeds. …”
