Therapeutic Study of Aloe vera Extract on Eimeria tenella Infection in Chicken
To evaluate the therapeutic efficacy of Aloe vera extract against coccidiosis in chickens,the experiment was conducted by randomly dividing 180 chickens of 14 days of age into six groups:the negative control group(not infected with coccidia and not administered),the positive control group(infected with coccidian and not administered),diclazuril treatment group(0.2 mL/L diclazuril),low(0.5 g/L),medium(1 g/L)and high(2 g/L)Aloe vera extract treatment groups.Each group had 3 replicates and each replicate had 10 chickens.Except for the negative control group,the chickens from other groups were infected orally with 7.5×104 Eimeria tenella sporulated oocysts at 14 days of age.The anticoccidial index(ACI)was calculated based on the statistical relative weight gain rate,survival rate,cecum lesion score and oocyst value at 21 days of age.The results showed that the relative weight gain rate and survival rate of the chickens from Aloe vera extract treatment groups were improved,and the cecum lesion score and oocysts per gramme(OPG)value were significantly reduced(P<0.05).High,medium and low Aloe vera extract treatment groups showed low anticoccidial effect with ACI of 154.23,145.94,122.93,respectively.The diclazuril group achieved a high anticoccidial effect with an ACI of 181.55.The results indicated that the add of 2 g/L Aloe vera extract to daily drinking water was partly effective in the treatment of coccidiosis in chickens.
