在哺乳动物研究中发现, 高原类群在缺氧条件下的有氧运动能力高于低海拔类群, 最大O2消耗率(maximal rate of O2 consumption, VO2max)[67], 血液、骨骼肌和肺氧弥散量[1,67], 最大心输出量(cardiac output)[68], 血氧亲和力[69]等方面有显著改善. 但以羊作为研究对象的报道极少, Anand等人[70]在对反刍...
(Heady 1960). In focus group interviews, Maasai, Samburu, and Borana elders in Kenya and Ethiopia recalled burning every several years to control bush encroachment, control tick and tsetse fly populations, and remove rank or overgrown grass with a high ratio of dead stems—allowing newer, more...

Human-edible protein from pastoral systems is produced much more efficiently, with protein input/output ratio between 1:4 and 1:21 in India, Sudan, New Zealand, Mongolia, Ethiopia and Kenya, compared with ratio below 1:1 in high external input systems (Steinfield et al., 2010) (Table 1.2...
ITL involves treating livestock living in close proximity to humans with an insecticide. Zoophagic malaria vectors may die or have reduced reproductive success after feeding on ITL, which could protect humans by driving down the vector population responsible for malaria transmission. Alternatively, there...
