Abstract: To explore the effects of Citrus and sweet and sour agent on feed intake and the production of cows, totally 45 healthy and free from disease with the similar, body condition, feed intake, parities, milk days and milk production, randomly divided into three treatment groups (n=15), the control group and experiment group 1 and 2 groups. Test group 1, 2, respectively in the basic diet according to concentrate adding 1%Citrus and sweet and sour agent (20g/d citric acid and 10g/d sweet), forecast of 14d, 90d trying period. Results showed that during the trial period, dry matter intake for the test group 1 increased by 3.80%compared with control subjects (P<0.05), the milk yield increased by 2.15% (P<0.05). Comparing with the experiment group 2 dry matter intake for the experiment groups 1 were increased by 2.45%(P<0.05), the average butterfat rate was reduced by 2.59%(P<0.05), the average milk protein rate increased by 3.44% (P<0.05). The 1 ~ 30d dry matter intake of two test groups significantly increased by 2.51%(P<0.05) than the control group, the 61~90d milk yield was signiifcantly increased by 3.34%than the control group (P<0.05). The diet concentrate added on the basis of Citrus and sour, sweet agent can signiifcantly improve cows dry matter intake and milk production, increase the rate of breast milk protein and milk protein production, reduce the milk somatic cell count, and thus improve the production performance of dairy cows, but adding Citrus is obviously better than the effect of sweet and sour agent.
