[Objectives]The study was conducted to evaluate the effects of diet with"Lianhuang"additive of Chinese herbal medicine(LACHM)on growth performance and metabolic rates of dietary nutrients in Donglan black chickens(DBCs).[Methods]80 DBCs aged 1 d were blocked into 4 groups randomly and assigned to 6 replicates in each group with 20 chicks in each *** A as control group fed basal *** B,C and D as treatment groups consumed the basal diet added with 0.25%,0.50%and 1.00%of LACHM,respectively during the test period of 70 *** the end of feeding test,24 DBCs with similar body weight from each group were chosen out and used for a metabolism test to determine the metabolic rates of dietary nutrients from each *** metabolism test was conducted as the same design as the feeding test and the DBCs from each group were fed the same diet as previous test.[Results]The ADG of chickens in the test increased by 5.00%-9.15%(P0.05),*** ADFI in the stage of 36-49 d from group A was 6.04%more than that from group B(P0.05).The F/G in the stages of 22-35 and 1-70 d from group B was 6.32%and 3.41%lower than those from group A(P<0.05),respectively,and even 11.43%and 7.31%lower in the stages of 36-49 and 1-49 d from group B than those from group A(P<0.01),*** F/G of group C in the stage of 36-49 d was also 10.15%lower than that of group A(P<0.05),and still 5.29%lower than that from group A in 1-

[Objectives]To study the effects of Chinese herbal medicine feed additives on the growth performance and dietary nutrient metabolic rate of black-one chickens.[Methods]480 pieces of 1-day-old Donglan Black-bone Chickens were selected and divided into 4 groups,with 6 replicates in each group,with 20 pieces in each *** them,group A was the control group and was fed the basal diet;the groups B,C,and D were the experimental groups,which were separately supplemented with 0.25%,0.50%and 1.00%of Chinese herbal medicine additives in the basal diet,and the experimental period was 70 *** the end of the feeding experiment,24 experimental chickens with similar body weight were selected from each group,and the same design of the feeding experiment was used to continue to feed the original diet for the metabolic experiment to determine the nutrient metabolic rate.[Results]Except the 50-70 d stage,the average daily gain(ADG)of group B in other stages was increased by 5.00%-9.15%(P0.05);at 36-49 d,the average daily feed intake(ADFI)of group A was higher than that of group B by 6.04%(P0.05);at 22-35 and 1-70 d,the feed to gain ratio(F/G)of group B was 6.32%and 3.41%lower than that of group A(P<0.05),and at 36-49 and 1-49 d,the F/G of group B was even lower;at 36-49 d,the F/G of group C was 10.15%lower than that of group A(P<0.05),and at 1-49 d,it was also lower than that of group A by 5.29%(P<0.01);there was no significant difference between t
