Parvizi O, Radmanesh S, Taherkhani R., Effects of fenugreek supplement on performance, immune markers and microbial flora in Ross 308 broilers, Onl J Vet Res., 24 (3):134-138, 2020. We report effect of fenugreek supplement on immune markers and intestinal micro-flora in broiler chicks. Groups of one day Ross 308 broiler were fed basal diet with or without 100, 200 and 250 ppm fenugreek essential oil. Feed intake, body weight gain and feed conversion ratio were calculated at 30 and 38 days. Wing vein blood was taken for red blood cell and Influenza and Newcastle disease vaccine antibody levels and carcass traits were determined. Compared with controls, we found no differences in feed intake between any group. However 200ppm fenugreek may have reduced (P < 0.05) daily weight gain (~13%), increased conversion ratios (12%) but reduced weight (9%) at slaughter. The higher dose of 250ppm fenugreek powder appeared to have decreased (P < 0.05) gizzard weight (~17%) but had no effect on intestine or liver weights. Results suggest that 100-200ppm Fenugreek increased influenza antibody titers ~13% but had no effect on Newcastle or sheep red blood cell antibody. Our more significant findings (P < 0.01) were 7-17% declines in intestinal Escherichia coli and 9-12% increase in lactobacillus spp. (Table 5) in broilers given fenugreek.
