This study investigated growth performance, intestinal organ development and blood indices of pullet chicks administered aqueous extracts of Petiveria alliacea root and leaves. A total of 288 day-old Isa brown pullets were randomly allotted into two groups administered aqueous extract of different parts of Petiveria alliacea (root and leaf) at four concentration levels (0, 15, 30 and 45 ɡ.l-1) making a total of 8 treatments. Each treatment was replicated three times with 12 birds per replicate. The experiment was arranged in a 2 × 4 factorial experimental layout in a completely randomized design. There were similarities (P >0.05) in feed intake, feed conversion ratio, weight gain and final weight across all treatments. Lowest (P <0.05) water intake was recorded in pullet chicks maintained on 30 ɡ.l-1 leaf extract (2726.90 ml/bird). Birds maintained on 30 ɡ.l-1 and 45 ɡ.l-1 concentration of extraction had the highest (P <0.05) caeca weight (0.75% of body weight). Birds administered root extract and leaf extract at 30 ɡ. l-1 and 45 ɡ.l-1 concentration levels recorded higher (P <0.05) white blood cell count compared to other treatments. Highest (P <0.05) lymphocyte differential was recorded in birds raised on 45 ɡ.l-1 root extract. Lowest (P <0.05) serum uric acid was recorded in pullet chicks administered 45 ɡ.l-1 root extract (3.07 mg.dl-1), while serum cholesterol was lowered (P <0.05) in all administered levels of extracts of Petiveria alliacea when compared to the control birds. The study concluded that administration of aqueous root extract of Petiveria alliacea at 45 ɡ.l-1 concentration level best enhanced immunity, reduced serum urea and cholesterol in pullet chicks without impairing their growth.
