EVALUATE THE EFFECT OF SOME PHYTOBIOTICS ON THE CONTROL OF NECROTIC ENTERITIS IN BROILERS CHICKEN

Abstract

The harmful economic impacts on chicken production are caused by the bacterium Clostridium perfringens , which is also responsible for necrotic enteritis in chicken. The study's objective is to assess the beneficial benefits of a few phytobiotics as substitutes for antibiotics when treating necrotic enteritis and broiler performance. Seven treatment groups were created at random from 280 broilers. All groups, except the negative control group, faced C. perfringens type A strain seven days after receiving sporulated coccidia oocyst inoculations. G3 and G4 received a basal diet containing 1 and 2 gm of curcumin /kg of diet, respectively. G5 was given a control infection, while G6 received a basal diet containing 1 and 2 gm of propolis /kg of diet. The results revealed that a high concentration of curcumin 1&2 gm/kg as a feed additive had a significant detrimental effect on chicken growth performance. Moreover, the total count of C. perfringens in the cecum was significantly increased and severe histopathological alterations in the intestinal mucosa, including severe sloughing of villi epithelium were detected. On the other side, Propolis, when added to the diet at a dose of 1-2 gm/kg ration, protected the digestive system and ameliorated the pathological lesions induced by the concurrent infections with Eimeria and C. perfringens. Consequently, a considerable decrease in the overall number of C. perfringens in the cecum, and restoration of the normal histological structure of the intestine and the lesions were mild compared to curcumin groups.
