Jejunal histomorphometry of salmonella enteritidis infected broiler chickens supplemented with red ginger and antibiotic

The current study aimed to examine the effect of red ginger supplementation on the jejunal villus histomorphometry of Salmonella enteritidis-infected broiler chicken and compare it tothe antibiotic’s effect. One-day-old broiler chickens (n=125) divided at random into five treatment groups:(1) chickens received standard broiler feed only (CON), (2) chickens received standard broiler feed and infected with S. enteritidis (SE), (3) chickens infected with S. enteritidis and supplemented with red ginger powder (2% of total feed) (RGP-SE), (4) chickens infected with S. enteritidis and given tetracycline (15 mg/kg b.wt.), and (5) chickens supplemented with red ginger powder (2% of total feed) without infection (RGP). Five chickens from each group slaughtered on day-35 of the experiment. Samples of jejunum from each treatment group were collected and stained with hematoxylin-eosin for histomorphometry analysis. The parameters examined included villus height, villus width, villus surface area, crypt depth, and villus/crypt ratio. Procured data were statistically analyzed using one-way ANOVA and Tukey’s HSD test. The results (mean ± SD) between treatment groups were regarded as significantly different at P<0.05. The results indicated that both red ginger and tetracycline did not significantly affect the jejunal villus histomorphometry of infected and non-infected chickens. Red ginger and tetracycline supplementations could not effectively improve the intestinal histomorphometry of S. enteritidis-infected broiler chickens.
