Balanced feeding could improve productivity of cross-breed dairy cattle in smallholder systems (Tigray, northern Ethiopia) por Alemayehu, Tadesse, Matovu, M., Tesfay, Y., Breusers, M., Fievez, Veerle

“…In the other groups imbalanced diets were fed, of which 26% were protein deficient (group 1), whereas (surprisingly) 56 % of the farms included more than 10% NSC in their diet, which resulted in an excessive protein supply. The milk yield of group 1 potentially could be increased by 114% with an additional supplement of 1.6 kg of NSC. …”

Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia por Moges, M.A., Schmitter, Petra S., Tilahun, Seifu A., Steenhuis, Tammo S.

“…The parameter efficient semi-distributed watershed model (PED-WM) was calibrated and validated in the Ethiopian highlands to simulate runoff and associated sediments generated through saturation excess. The P module added to PED-WM was used to predict dissolved (DP) and particulate P (PP) loads aside from discharge and sediment loads of the 700 ha of the Awramba watershed of Lake Tana basin. …”

Types of silvopastoral systems: adding trees to pastoral/rangelands. por Beltran, Marcelo Javier, Cambareri, Gustavo Sebastián, Banegas, Natalia Romina, Peri, Pablo Luis, Colcombet, Luis, Martínez Pastur, Guillermo, Lencinas, Maria Vanessa, Rodríguez Souilla, J., Cellini, Juan Manuel, Cosentino, Vanina Rosa Noemi

“…Silvopastoral Systems (SPS) have been identified as an efficient land management strategy to increase the performance of animal and tree production, livestock welfare (Esquivel, 2017), and improve carbon (C) sequestration in soil and in trees to offset livestock emissions (Figueiredo et al., 2017). These systems are a type of livestock agroforestry, which associates trees and/or shrubs with pastures (Mosquera-Losada et al., 2006; Chará et al., 2020). …”
