Immunopathological studies on Escherichia coli infected broiler chickens fed on Aloe vera leaf extract.

Escherichia coli infection is the major bacterial disease affecting the poultry industry and the continuous use of antibiotics in poultry farming has resulted in antibiotic resistance. So this study was planned to evaluate the use of an ecologically safe alternative to fight against infections. The leaf gel of the Aloe vera plant was selected based on its antibacterial activity assessed in in-vitro tests.

Ameliorating effect of Withania somnifera root extract in Escherichia coli-infected broilers.

The present study was undertaken to investigate the effect of aqueous Withania somnifera root (WSR) extract in broiler chicks experimentally infected with Escherichia coli O78 @ 10 CFU/0.5 ml intraperitoneally. Clinical signs and mortality due to colibacillosis observed in infected chicks were mild and lasted for short duration in WSR extract supplemented group as compared with the nonsupplemented group.
