Abstract:
This article determines and draws conclusions on the changes in live weight across age dynamics of
offspring obtained from mating Camelus dromedarius and Camelus bactrianus camels in various pasture
conditions of the Ustyurt Plateau in the Republic of Karakalpakstan.

Introduction:
Today, Australia, Mongolia, Argentina,
Afghanistan, Namibia, and the Republic of South Africa
are among the countries primarily engaged in camel
husbandry on a global scale. The worldwide population
of two-humped camels exceeds 2 million. In the
aforementioned countries, a considerable number of
scientific studies have been conducted to investigate
camel biology, increase their productivity, and improve
their breeding characteristics. In recent years, milk and
meat products obtained from camel husbandry have
become crucial in addressing food security concerns.
Consequently, focusing on the quantitative and
qualitative indicators of camel products and utilizing
modern innovative feeding methods remain highly
relevant [4. https://24.kz/ru/news/economyc/item].
Determining the age, sex, constitutional types, and
dependence of productivity on pasture types, as well as
proper feeding, plays a crucial role in enhancing the
breeding potential of camels [1.p.6
–
22].
In
the
Republic
of
Uzbekistan,
including
Karakalpakstan, camel breeding thrives in desert areas
with vast natural fodder lands that are largely
inaccessible to other livestock. The two-humped
camels raised in this region are notable for their wool
productivity, enabling effective utilization of these
characteristics.
Simultaneously,
developing
and
implementing efficient technologies for camel product
production is essential for ensuring food security,
elevating the population's living standards, and
generating new employment opportunities [2.p. 14
–
27].
Experimental site
: The experimental work for the
dissertation titled "Selective characteristics of offspring
obtained from mating Camelus dromedarius and
Camelus bactrianus in the conditions of the Ustyurt
plateau" was conducted from 2024 to 2026 at the
specialized camel farms "Ata-Mura" and "Konratli Aq
niyet," which belong to the Ustyurt rural community in
the Kungrad district of the Republic of Karakalpakstan.
Research objective
: To study the live weight in age
dynamics of offspring obtained from mating Camelus
dromedarius and Camelus bactrianus camels.
METHODS
The live weight of camels was determined with an
accuracy of ±5.0 kg using autoplatform scales under

farm conditions. In summer pasture conditions, where
the use of autoplatforms was not possible, the live
weight of camels was determined using a formula
based on the methodology from the bonitation manual
by Baymukanov D.A. (2001). In this case, the
determination of the camels' live weight was carried
out using a special formula that took into account the
age coefficient. The study of growth and development
was conducted by identifying specific parameters at
predetermined times. Monitoring the growth rate of
young camels was carried out during the newborn
period (1 day old), at 1 month of age, and throughout
the subsequent age dynamics.
RESULTS
Increasing the productivity of one- and two-humped
camels can be achieved by utilizing their biological
potential, primarily based on the laws of growth and
development. Growth patterns are determined by the
quantitative growth of tissues, organs, and the entire
organism during ontogenesis, the increase in cell
numbers, and the intensity of cell mass multiplication.
These patterns are influenced by the organism's
hereditary characteristics, age, physiological state, and
environmental
conditions.
The
growth
and
development indicators of camels differ from other
animals but follow general biological principles [3.p.
279
–
285].
Based on the results of our experimental work, we
studied the changes in live weight of young camels at
different ages under the conditions of the Ustyurt
plateau. These data are summarized in Table 1 below.

Analysis of the data in Table 1 shows that different
indicators can be observed depending on the camel
breed. At birth, the weight of C. Bactrianus calves was
35.6±3.13 kg, while for C. Dromedarius calves, it was
33.2±32.9 kg. This indicator in the hybrid offspring
obtained from these breeds was 34.5±32.9 kg. If C.
Dromedarius calves are taken as a baseline of 100, then
C. Bactrianus calves showed a 7.2% advantage, and the
hybrid offspring showed a 3.9% advantage.
This trend was also observed in younger animals. At 6
months of age, the live weight of C. Bactrianus calves
was 21.9±2.1 kg, while C. Dromedarius calves weighed
114.4±11.9 kg, and the hybrid offspring obtained from
these species reached 129.6±11.8 kg. Maintaining the
aforementioned trend, C. Dromedarius calves showed
a 30.4% advantage, and the hybrid offspring
demonstrated a 13.3% superiority.
It can be stated that in terms of live weight, young
calves of C. Bactrianus demonstrated more rapid
growth compared to C. Dromedarius calves, while
hybrid offspring occupied an intermediate position.
The absolute growth indicators of young calves play a
significant role in the development of their future
meat, milk, and wool productivity. The manifestation of
these indicators is primarily and directly related to their
adequate nutrition.
The absolute growth indicators from our experimental
work are presented in Table 2 below.

According to the data in Table 2, from birth to 1 month
of age, C. Bactrianus calves weighed 18.0±1.2 kg, while
C. Dromedaries calves weighed 11.3±1.2 kg, and the
2/1 hybrid generation occupied an intermediate
position at 13.8±1.3 kg. This trend persisted in
subsequent age dynamics, with C. Bactrianus calves
showing a slight advantage in growth rate. The 2/1
hybrid generations maintained an intermediate
position across all age groups. It should be noted that
from the 4-month period onward, the growth rate of all
experimental calves accelerated. It is during this period
that the demand for roughage increases.
Figure 1.
Absolute growth rate of hybrid offspring (%)
In hybrid camel calves, the absolute growth indicators
(Figure 1) primarily showed an intensive increase in live
weight from 3 months to 6 months of age. From birth
to 3 months of age, a change of 2.2-13.1% was
observed. From 4 months of age, the growth rate
increased by 28.3%, and from 6 months of age, it
rapidly increased by 39.1%.
CONCLUSION
In the age-related weight dynamics of offspring
obtained from mating Camelus dromedarius and
Camelus bactrianus camels, the calves of Camelus
dromedarius demonstrated superior growth rates in
terms of live weight compared to the calves of Camelus
bactrianus. The hybrid offspring of 2/1 generation
occupied an intermediate position in this indicator.
