[Objective] To investigate the changes in milk production and composition throughout the lactation cycle of fully housed Bactrian camels in Hami City. [Method] 105 fully housed Bactrian camels were selected for the experiment.The milk production and composition from April to March of the following year were measured and analyzed. [Result] （1）Changes in milk production：After giving birth to lambs,the milk production of female camels gradually increased.The highest milk production in July reached 4.62 kg/d,and then gradually decreased.The lowest milk production in March of the following year was 2.43 kg/d.The milk production in summer（June August） was significantly higher than other seasons.（2）Milk composition analysis：The fat content of milk is 3.27%~5.77%,and it is significantly higher in autumn and winter than in spring and summer.The milk protein content ranges from 3.81% to 4.48%,and the lactose content ranges from 5.08% to 6.33%,reaching its lowest point in winter.（3）Correlation analysis of milk production and milk composition：Milk production is significantly negatively correlated with milk fat rate（P<0.05）,significantly positively correlated with lactose rate（P<0.05）,and positively correlated with fat free solids rate,milk protein rate,and ash content rate（P>0.05）.The milk fat content is significantly negatively correlated with the fat free solids,ash content,and lactose content（P<0.01）,and significantly negatively correlated with the milk protein content（P<0.05）.The non fat milk solids content is significantly positively correlated with the milk protein content,ash content,and lactose content（P<0.01）,and the milk protein content is significantly positively correlated with the ash content and lactose content（P<0.01）.The ash content is significantly positively correlated with the lactose content（P<0.01）. [Conclusion] The postpartum milk production of camels gradually increases,reaching its peak at 3~5 months,and then gradually decreases thereafter.The changes in milk composition are closely related to management,milk production,and feeding level.
