Abstract: In order to know the effects of supplementing with protein feed and energy feed on the milk yield of grazing Alashan Bactrian camel, corn and concentrate supplement were selected to make the supplement experiment and observe its effects of increasing milk yield. The results showed that the increasing effects of milk yield of supplementing grazing Alashan Bactrian camel with protein feed was better than that with energy feed. The milk yield of Alashan Bactrian camel in test group 2 at the end of the test increased 277 g/（d. head ） than that before the test （P〈0.01 ）. The milk yields of Alashan Bactrian camel in energy feed group and control group were lower than that before the test.
