Abstract
To examine the inhibitory effect of whole grain paddy rice diet (WPR) feeding on the colonization of Campylobacter jejuni in the cecum of broiler chicks, we performed the following examination. Sixty female broiler chicks (14 days of age) were allocated into two groups, thirty birds were fed a ground corn diet (GC) as a control group, and 30 chicks were fed WPR as an examination group. After feeding with the different diets for 16 days, six chicks were selected from each group (12 chicks in total), and each chick was inoculated with 2×103 colony-forming units of C. jejuni GTC03263. Forty-eight hours after the bacterial inoculation (the birds continued to be fed with the corresponding diets after the bacterial inoculation), the chicks (six from each group) were killed and dissected to detect bacterial colonization in the cecum. The other six chicks were dissected to weigh the chick gizzard and to measure the pH of its contents. No bacterial colonization was observed in the cecum of chicks in the WPR group, whereas bacteria were found in the cecum of five of six chicks in the GC group. The average ratios of gizzard weight to body weight of the WPR-fed chicks was significantly higher than that of the GC-fed chicks, whereas the average pH value of the gizzard contents was not different between the two groups. These results suggest that WPR feeding in broiler chicks has a positive effect on development of the gizzard muscle and grinding activity of the gizzard. Increased grinding activity may eliminate the regional differences in pH within the gizzard, resulting in less bacterial survival in the gizzard and then less bacterial colonization in the cecum of WPR-fed chicks than in GC-fed chicks.
