Study on the preventive and curative effect of plant extract combined with probiotics on Eimeria chicken

Abstract

The aim of this study was to investigate the effect of plant extracts combined with probiotics on the prevention and treatment of Eimeria tender infection in chicken. A total of 180 12-day-old coccidia-free chicks were randomly divided into 6 groups with 30 chickens in each group. The experimental groups were as follows: group A (blank control group), Group B (positive control group) (infected with coccidia without adding anti-coccidia drugs), group C (probiotic group), group D (plant extract test group), group E (probiotic + plant extract test group) and group F (dickezulil group). Except the blank control group, 5×104 oocysts of Eimeria teniculare infected orally at the age of 14 days, respectively. From the day of attack, groups A and B were fed a basic diet without anticoccidial drugs, groups C, D and E were fed diets containing corresponding additives, and group F was fed dickezulil in drinking water. The results showed that the addition of probiotics + plant extracts was superior to the addition of probiotics and plant extracts alone in the drinking water group to increase body weight, reduce cecal lesions and reduce the number of oocysts per gram of cecal contents of infected chicks, and the anticoccidial index was 160.91, which could achieve a good anti-coccidioides effect 160≤ACI < 180. It is concluded that plant extract combined with probiotics has a good effect on preventing and treating Eimeria teniculata.
