MACROSTRUCTURE OF THE ESOPHAGEAL TONSIL OF VACCINATED CHICKENS
Abstract
The macrostructure of the esophageal tonsils of the chickens
cross Chever 579 in the age aspect (1-day-old to 3 year-old) was studied. 1-
day old, chicks were vaccinated against Marek's disease and infectious
bronchitis, and 12-, 30-, 80- and 100-day-old chicks were revaccinated
against infectious bronchitis. In carrying out the work, conventional
macroscopic methods of morphological research were used.
Macroscopically, the chicken’s esophageal tonsil becomes noticeable at
10 days of age. It has the appearance of a thin whitish-pink ring-shaped strip.
In 15-day old chicks the mucosa folding of this area deepens, the color of the
esophageal tonsil changes to pale yellowish. Her surface becomes tuberous
and well developed in older birds. Linear measurements of esophageal tonsils
change with increasing age of chickens. The maximum values of the
parameters of its length and width are reached in 120-day-old birds (length –
27,83 ± 0,87 mm and width – 6,63 ± 0,51 mm), after which the length
measurement remains almost unchanged, and the width decreases and
reaches its minimum value at the age of 3 year (4,80 ± 0,60 mm).
