Summary. To
evaluate the influence of certain temperamental characteristics on the level of
sex hormones in the blood plasma of female Bull Terriers, an experiment was
conducted with 15 female Bull Terriers. Pregnancy screening was performed
on 21st–28th days after ovulation). The
material for the study were blood plasma samples of bitches obtained at
different stages of the sexual cycle, in which the levels of estradiol,
follicle stimulating hormone, luteinizing hormone, and progesterone were
measured. The assessment of temperamental traits was performed at the design
stage of the experiment using the standardized C‑BARQ methodology.
One-way analysis of variance was used to determine the strength of the influence
of individual temperament traits on the level of sex hormones in the blood
plasma of bitches. According to the results of the experiment, it was found
that the degree of fear and anxiety in bitches significantly affects the
content of follicle-stimulating hormone, estradiol, and luteinizing hormone in
the blood plasma of bitches three days before, during and
120–150 days after the LH surge (ղ²ᵪ = 0.27–0.55
(P ≤ 0.05). The excitability of bitches affects the level of
follicle stimulating hormone, luteinizing hormone, and progesterone on the day
of the LH surge — ղ²ᵪ = 0.32
(P ≤ 0.05). In addition, the level of excitability affects the
level of progesterone on the 9th day after the
surge — ղ²ᵪ = 0.35
(P ≤ 0.05) and the level of luteinizing hormone on the 2nd,
4th, 55th–60th days and after the
LH surge — ղ²ᵪ = 0.26–0.43
(P ≤ 0.05). The degree of aggression affects the luteinizing
hormone level two days after the surge and the progesterone level on 55th–60th days
after the LH surge (ղ²ᵪ = 0.34–0.36;
P ≤ 0.05). Training ability and obedience affect follicle
stimulating hormone levels (the day before the surge, and on 4th, 9th,
and 35th–40th days after the LH surge (ղ²ᵪ = 0.30–0.52;
P ≤ 0.05), luteinizing hormone (on 9th day
after LH surge, ղ²ᵪ = 0.54;
P ≤ 0.01), and progesterone (on 35th–40th days
after LH surge, ղ²ᵪ = 0.34;
P ≤ 0.05)
