Abstract：This study aimed to investigate the effects of house feeding and grazing+supplementary feeding conditions on the lactation performance and serum biochemical indicators of Bactrian camels.A total of 100 healthy lactating camels were randomly divided into two groups,with 50 replicates per group and one camel in each replicate.The control group(group A)was fed in a house,and the experimental group(group B)was fed with grazing+supplementary feeding.The trial lasted for four months.The results showed that the average daily milk yield of Bactrian camels in group A and group B was the highest in July,and the milk yield showed a decreasing trend after July.The average daily milk yield of group A was higher than that of group B.The income of camel milk in group A was extremely higher than that in group B(P<0.01),and the profit of camel milk in group B was significantly higher than that in group B(P<0.05).In July,the non-fat milk solids rate of camel milk in group A was extremely higher than that in group B(P<0.01),and the ash and lactose concentrations in group A were significantly higher than that in group B(P<0.05).The milk fat percentage of group A was significantly lower than that of group B in August(P<0.05).In September,the non-fat milk solids rate of group A was significantly higher than that of group B(P<0.05),and the ash rate of group A was extremely higher than that of group B(P<0.01).Non-fat milk solids rate was positively correlated with ash rate and lactose rate(P<0.01),milk protein rate was positively correlated with ash rate and lactose rate(P<0.01),and ash rate was positively correlated with lactose rate(P<0.01).The concentrations of serum total protein(TP)and albumin(ALB)in group B were extremely higher than those in group A(P<0.01),and the content of glucose(GLU)in group B was significantly higher than that in group A(P<0.05).The study indicates that the grazing+supplementary feeding mode can enhance the disease resistance of camels,but under the conditions allowed by the supporting facilities and equipment of the farm,the breeders can increase the breeding income through the house breeding,and the change of milk composition is closely related to the milk production and feeding method.
