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 [21] 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.
Villus 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 height,
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.
Villus height was measured in at least 10
villus longitudinal sections (4 animals per group).
