Abstract
Present Study is observation of Histopathological changes of
Thyroid Gland In Buffaloes. Tissue samples i.e.thyroid glands
were collected from the 300 buffaloes slaughtered at Municipal
Slaughter House, Balapur Akola. Thyroid glands were cut in to
small pieces for further histopathological processing. They were
dehydrated in ascending (50%, 70, 95, 100%) order of alcohol,
cleared in xylene and embedded in paraffin and sections of 4-6
micro diameter were obtained and stained with haematoxylin and
eosin stain. The animals slaughtered were certified as
non-productive. During present study mean, standard deviation
and standard error were calculated as per the standard
procedure. Microscopically 76.96% glands were normal, incidence
of colloid goitre was recorded in 11.72% thyroid, parenchymatous
goitre in 1.89% thyroid, increased interfollicular spaces and
fibrotic condition in 9.66% glands. Haemorrhages and congestion
was observed in 2.75% thyroid glands. Conclusion of this study
is colloid goitre due to distention and enlargement of number of
follicles, congestion in the thyroid gland occurs as the part of
more general syndrome and Interfollicular hemorrhages occurs due
to distribution of RBCs, escaped from blood vessels.
