farms the sheep were carried on the wrist muscle that records the wrist and the elbow muscle that bends
the wrist. Animals in the 3-day, 3, 6, 12, 18, 36, and 60-month stages of postnatal ontogeny were
obtained for scientific studies with the wrist muscle that records the wrist and the elbow muscle that
flexes the wrist. A common morphological method was used to obtain the morphometric dimensions of
the muscles.
All numerical data obtained as a result of scientific research were mathematically processed by the
method of Ye.K. Mercury.
To determine the dynamics of muscle-age change, the growth factor was determined using a formula
developed by K.B. Svechin.
Mathematical-statistical analysis was performed in a computer's Microsoft Excel spreadsheet using
Student and Fisher criteria.
The results obtained and its discussion.
It is noted that the morphometric dimensions of the sphincter and flexor muscles affecting the wrist joint
of the forefoot of sheep show specific dynamics at different physiological stages of postnatal ontogeny
and the influence of the natural ecological environment on these indicators. done.

In absolute conditions, the absolute value of the wrist muscle length of the wrist brace increases rapidly
from 3 days to 3 months of postnatal development, from 8.14 ± 0.14 cm to 13.38 ± 0.19 cm or during
the same period. The coefficient of swelling reaches 1.64 times, at 6 months it does not change
significantly, and at 12 months it increases (15.16 ± 0.15 cm, K = 1.14; r <0.01). The 18-month peak
(17.52 ± 0.23 cm, K = 1.15; r <0.02) was noted. Significant decrease in this muscle mass in 36-month-
old sheep (13.06 ± 0.13 cm) and its increase again in 60-month-old sheep (15.64 ± 0.2 cm, K = 1.19; r
<0.02 ), postnatal ontogeny was found to increase its growth rate by 1.92 times during the period from 3
days to 60 months of study.
The absolute measurement of the width of the wrist muscle, which records the wrist, increases rapidly
from 1.84 ± 0.04 cm to 2.64 ± 0.05 cm (r <0,) in proportion to its length from 3 days to 3 months of
postnatal ontogeny in sheep. 02) or 1.43 times the growth coefficient, at 6 months it decreases by 2.4 ±

an increase of 3.76 ± 0.1 cm, at 36 months it decreased to 2.82 ± 0.06 cm, and at 60 months it increased
slightly (3.0 ± 0.06 cm; p <0.02) was observed.
The absolute value of this muscle thickness ranged from 1.32 ± 0.04 cm to 1.62 ± 0.04 cm (K = 1.22; r

<0.03) at 6 months, almost unchanged at 12 months, and by 2.06 ± 0.07 cm at 18 months. (K = 1.13; r
<0.04) was noted. This muscle index decreased significantly at the 36-month stage of postnatal
development (1.8 ± 0.05 cm; r <0.05) and was highest at 60 months compared to other ages (2.26 ± 0.05
cm, K = 1, 25) was determined to occupy the degree.
The absolute value of wrist muscle weight in the first 3 days of postnatal ontogeny of sheep of
the genus Gissar was 7.22 ± 0.13 g, which gradually increased to 18 months, i.e. 28, 8 ± 0.57 g (K =
1.48; r <0.02), a sharp decrease in it at 36 months (19.5 ± 0.39 g), 25.76 ± 0 at 60 months, 56 g (K =
1.32; r <0.03) and its growth rate increased 3.56 times from 3 days to 60 months.
In absolute conditions, the absolute size of the wrist muscle, which records the wrist brace, increased
rapidly from 3 days to 3 months of postnatal ontogeny, from 7.7 ± 0.01 cm to 12.68 ± 0.21 cm (r <).

(K = 1.19; p <0.01). and at 36 months of age, it decreased significantly (12.46 ± 0.25 cm) and at 60
months it increased slightly (13.62 ± 0.22 cm; r <0.02). It was noted that the coefficient of growth of
this muscle was 1.76 times during the studied stages of postnatal development of sheep.
The absolute measurement of this muscle width was from 1.58 ± 0.05 cm to 2.32 ± 0.08 cm (r <0.04)
from the first 3 days to 3 months of postnatal ontogeny in sheep of the Gissar breed. Increase to 1.46
times, decrease it slightly at 6 months (2.18 ± 0.06 cm, K = 0.93), increase again at 12 months (2.54 ±
