Antimicrobial, immunomodulatory and hepatomodulatory effects of aqueous extracts of Petiveria alliacea root and leaf on growing pullets

Aim of study: To evaluate antimicrobial, immunomodulatory and hepatomodulatory effects aqueous extracts Petiveria alliacea L. (Guinea hen weed) root leaf on growing pullets.Area Abeokuta, Nigeria.Material methods: Two hundred eighty eight eight-weeks-old Isa-brown pullets were divided into treatments which consisted in birds administered or at four different concentrations (0, 15, 30 45 ɡ/L). Each treatment was replicated three times with 12 per replicate.Main results: Oocyst counts lower (p<0.05) extract (78.42 opɡ) compared (103.58 opɡ). ɡ/L other treatments. Bacteria reduced extract. Pullets recorded lowest bacteria count. Bursa thymus weights increased the control. had highest antibody titre against Newcastle disease vaccine 8.80, 8.86, 8.74 8.80 (log2) respectively. There fatty infiltration liver control birds, while hepatocytes appeared normal P. extracts.Research highlights: performed best as immune-stimulating hepato-protective agent pullets. This study highlights allicaea a valuable antimicrobial immunostimulating poultry production.
