This study is aimed to appraise the impact of dietary supplementation with Echinacea purpurea (EP) in broiler chickens infected by pathogenic E. coli. Eighty-one-day-old chicks of both sexes, commercial Hubbard chicks, were divided into 4 groups. The first was kept as normal control, the second was supplemented by EP (5 mg/kg feed) from the first day to the end, where the third was infected orally by 1 ml E. coli O78 at 107 CFU intra-crop at 7 days old, while the last group was supplemented by EP and infected by the E. coli O78 as previously described . E. coli-infected chicks disclosed severe symptoms with mortality 30%. Where, the infected and EP supplemented group showed less clinical symptoms and 15% mortality. EP-supplemented groups showed a significant improvement in their body weight in comparing with infected group. E. coli-infected chickens revealed a significant drop in lymphocytes’ number with a significant elevation in monocyte and heterophils with non-significant changes in total leucocyte count when matched with gp. (1), while the fourth group revealed non-significant changes in total leucocyte with a significant drop in heterophils and monocyte and a significant elevation in the lymphocytes matching with the 3rd group. Serum biochemical markers of liver, kidneys, and immunological parameters showed sever adverse alterations associated with E. coli infection. Dietary supplementations with Echinacea purpurea improve the final body weight and immune response of non-infected chicks and have a respectable effect for facing E. coli infection. EP improves hematological and serum biochemical adverse effects occured by E. coli infection. Histopathology of liver, kidneys, intestines, and spleen confirms these alterations.

Impact of dietary supplementation with Echinacea purpurea on growth performance, immunological, biochemical, and pathological findings in broiler chickens infected by pathogenic E. coli

This study evaluated the potential benefit of providing dietary supplements to broiler chickens infected by pathogenic Escherichia coli with Allium sativum (A. sativum). Eighty-one-day-old Hubbard chicks were allocated into four groups (20 for each). The first was a control group (no supplement and not infected). The second received supplements of A. sativum 1 g/kg feed from day 1 to the end and was not infected. The third group was experimentally infected orally at 7 days old with E. coli O78 107 CFU intra-crop and received no supplement. The last group was supplemented with A. sativum and infected with the E. coli O78 as described previously. Chickens infected by E. coli had significantly low lymphocytes and a significant rise in heterophils and monocytes with non-significant changes in total leukocytic count (TLC) compared with the control. The fourth group had non-significant alterations in TLC with significantly low monocytes and heterophils and a significant rise in lymphocytes compared with the third group. The biochemical values of hepatic enzymes, renal, and immunological indicators had severe argumentative alterations related to E. coli infection. Dietary supplementation with A. sativum recovers the chickens’ immune indicators in non-infected groups and has an immune-stimulatory effect on E. coli infection. In conclusion, A. sativum mitigates hematological, biochemical, and antioxidant alterations induced by experimentally E. coli infection in broiler chickens.
