ABSTRACT: To
determine whether dried fermented ginger (DFG), fermented with Japanese mugwort
silage juice, could be replaced by fermented corncob powder (FCP) as a of feed ingredient
source without significant body weight decrease or damage to visceral organs
(using gross anatomical observation), to intestinal villi (using light
microscopy), or to the epithelial cells on the villus apical surface (using
scanning electron microscopy) the following investigation was performed. Sixty-four
male broilers were allotted to 4 groups: a basal diet group (control group),
and basal diet groups with DFG at a level of 50 ppm; with DFG at 50 ppm and FCP
at 250 ppm (50 ppm DFG + 250 ppm FCP group); and with FCP at a level of 500 ppm
(500 ppm FCP group). Feed intake, body weight gain, feed efficiency, carcass
quality, small intestinal length and weight, and visceral organ weight were not
different among groups. Furthermore, regarding intestinal villus height, villus
area and crypt depth, a significant difference was not found among the groups.
When these values of the control were expressed as an index of 100, the
duodenal villus height of the 50 ppm DFG + 250 ppm FCP group and the 500 ppm FCP
group were 114 and 119, respectively. The duodenal villus area of the 50 ppm
DFG + 250 ppm FCP group and the 500 ppm FCP group were 125 and 158,
respectively. These villus heights and areas are thought to be activated. On
the epithelial cells on the villus apical surface in the duodenum and jejunum,
the 50 ppm DFG + 250 ppm FCP group had protuberated cells into the intestinal
lumen and deeper cells at the sites of
recently exfoliated cells, suggesting that these cells are activated. The
present results indicate that small amounts of fermented corncob powder can be
used as a feed supplement when mixed with fermented ginger powder, due to the
synergy between the two ingredients, resulting in a 6% increase in body weight
gain。
