J. Bires et al., CLINICAL AND ULTRASONOGRAPHIC FINDING ON THYROID-GLAND OF RAMS DURINGADMINISTRATION OF KALIUM IODATUM, Veterinarni medicina, 43(6), 1998, pp. 179-185
The dynamics of triad values, general health condition, palpation and
ultrasonographic findings on thyroid glands of rams with various form
of clinical manifestation of goitre during therapy with kalium iodatum
. An experiment included 9 breeding Merino rams at the age of 2.5 year
with clinically developed goitre form. Experimental group (6 rams) wa
s administered kalium iodatum in the feed mixture at a dose of 0.5 g/a
nimal/day during 42 days. The control group without treatment consiste
d of three rams. Dynamics of body temperature had a similar trend in b
oth the groups and differences at this parameter found between treated
and untreated animals ranged within physiological boundaries. Breath
and heart rates reached during the whole experiment statistically insi
gnificantly higher values in experimental rams than in control rams. I
ncrease in the weight of experimental group started to be manifested c
ompared with initial values from 15th day and the highest weight was i
n these animals at the end of experiment (88.5 +/- 3.85 kg). The diffe
rence in weight between experimental and control rams was on day 42 of
the experiment on the level of significance p < 0.05. A slight degree
of apathy and inappetence was observed in all animals at the beginnin
g of experiment. Improved intake of the feed in treated animals starte
d to be manifested from day 8 but the improvement of the general healt
h condition and reactions to external stimuli were found on day 21 day
from the beginning of therapy. The changed palpation finding of thyro
id gland (hypertrophy, solid-elastic consistency) during application o
f kalium iodatum was gradually modified and the size of thyroid gland
was 2-4 x 1.5-2 cm on day 42 in different experimental animals. An ori
ginal solid-elastic consistency of thyroid gland changed in treated ra
ms to softer and soft. Symmetry, temperature, sensitivity and mobility
of thyroid gland was not affected by therapeutic procedure. Heteroech
ogenic character of ultrasonographic examination of thyroid gland in e
xperimental and control rams was characteristic at the beginning of ex
periment. Sonogramme showing almost homogenous echogeneity was typical
for thyroid gland in treated rams on day 42 of the trial. This findin
g corresponded to modified thyroid gland with relatively high represen
tation of colloid and lower representation of cells.
