Dietary supplementation with basil seed insignificantly (P>0.05) improved the villus
size of duodenum, jejunum, and ilium.
The subjectivity of C/V ratios is further highlighted by the fact that individual crypt tubes often enter their respective basins at an angle to ensure that they cannot be used, whereas the junctional zone between the start of a villus
and the upper margins of a crypt tube are ill-defined and hence extremely dependent on subjective assessments.
Nassiri Moghaddam and Alizadeh Ghamsari  observed that 1.0% and 1.5% dietary Gln supplementation increased the duodenum and jejunum VH, VW, and villus
surface area of broiler chickens at days 21 and 42 of age.
In light microscopic evaluation of the ileum preparations, a normal ileal tissue villus
histological structure was observed in Group I.
height, crypt depth, villus
: crypt ratio, and villus
area in the ileum showed similar results at hatch and at two days of age (Figure 1).
In the ileum villus
height in the control group was 391.06 19.72 m, while in the experimental group 456.78 27.18 m.
A significant difference can be observed among groups in villus
width, crypt depth and epithelial thickness of the intestine (p < 0.05).
The improvised device (standard pistol grip) was mounted onto the syringe which was being used to aspirate chorionic villus
samples or other large volume aspirations.
As crypt cells migrated up the villus
, has differentiated into secretary of goblet cells.
From face-on photos of the attachment disc taken at high magnification, we counted villus
density in as many one-square-micrometer (1 [micro][m.sup.2]) areas as possible for each antennule studied.
However, hydroalchoholic plant extracts from sage, thyme, and rosemary leaves did not exert any influence on intestinal villus
surface area and crypt depth.
height was measured in at least 10 villus
longitudinal sections (4 animals per group).
