Abstract: 【Objective】 This experiment was aimed to study the clinical effect of Lianhuachaiqin soluble powder on fever, cough, anorexia, thirst and drinking in chickens caused by wind-heat invading lung.【Method】 The broiler model of wind-heat invading lung syndrome was established by artificial challenge of chicken Infectious bronchitis virus.150 chickens with typical clinical symptoms of wind-heat invading lung syndrome were included in the experiment, and were randomly divided into 5 groups:Lianhuachaiqin soluble powder high, medium, low dose groups (Lianhuachaiqin soluble powder concentrations were 4, 2, 1 g/L, respectively), Ma Xing Shigan granule control group (1 g/L), and model control group, 30 chickens in each group.Another 30 chickens were used as healthy control group.Except for the healthy control group and the model group, the experimental groups were treated with drinking water continuously for 5 days.The changes of mental state, body temperature, respiratory symptoms, intake and drinking water of chickens before and after administration were recorded, and the indexes of immune organs and immune cell subsets in peripheral blood of chickens in each group were detected to comprehensively investigate the clinical effect of Lianhuachaiqin soluble powder.【Result】 The total effective rates of high and medium dose groups of Lianhuachaiqin soluble powder on fever and cough caused by wind-heat invading lung were 90.00% and 86.66% respectively, which were significantly higher than those in the model control group (P<0.05).And it had a good alleviating effect on the decrease of feed intake and the increase of drinking water in diseased chickens (P<0.05).On the other hand, the Lianhuachaiqin soluble powder could increase the immune organ index and promote the proliferation of CD3+, CD4+ and CD8+ T lymphocytes in the peripheral blood of diseased chickens, and the high and medium doses were significantly higher than those in the model control group (P<0.05).【Conclusion】 The results showed that Lianhuachaiqin soluble powder had good relieving and therapeutic effect on chicken fever, cough, loss of appetite and thirst caused by wind-heat invading lung. Combined with drug dose-effect relationship and economic cost, it was recommended that the clinical dosage of Lianhuachaiqin soluble powder was 2 g/L, given in drinking water for 5 days.
