Prevention and treatment of chicken coccidiosis by using Chinese medicinal herb Shachongbu

In order to assess the effect of Chinese medicinal herb Shachongbu against coccidiosis in chicken,135 chickens of 32-day-old were assigned to four groups,including Shachongbu treatment group(n=60),prevention group(n=30),chronic and acute toxicity group(n=30)and blank control group(n=15).The results showed that the anticoccidial index(ACI)was 181.7 and 173.4,relative weight-growth rate was 88.7%and 82.4%when 1%and 0.5%of Shachongbu was used against chickens coccidiosis,respectively.But in Sanziqiuchongfen control group,ACI and relative weight-growth rate was 173.5 and 80.5%,respectively,and the treatment effect was not as good as 1%of Shachongbu.In the prevention test,the average rate of weight increase in 0.5%and 1%of Shachongbu group was75.1% and 78.6%(P0.01),which was 66.6%higher than that of the healthy control group.In the toxicity test,5%and 10%dosage of Shachongbu had no toxic reaction,but the average rate of weight increase was decreased by 43.1%and 32.0%,respectively(P0.01),which indicated that high dosage of Shachongbu could inhibit chickens growth.When the chickens were given Shachongbu at 5 g/kg or 3 g/ kg for 4 days,no chickens were found to die,but the average rate of weight increase was decreased by 11.9%and 14.7%,respectively(P0.01).The results indicated that the herb Shachongbu composition could prevent and treat coccidiosis in chickens.
