Abstract:
The article presents the results of an experiment conducted under the sharply changing climatic
conditions of Karakalpakstan. It investigates the live weight indicators of young rabbits separated from the nest
at the ages of 30, 45, and 60 days.
Keywords:
Rabbits, live weight, height, age, lactation, climatic conditions.
Introduction:
Relevance of the topic
. In today's era of
steadily growing population, the issue of consistently
supplying the population with high-quality livestock
products is considered one of the most important
matters for everyone.
In our country, rabbit breeding is considered a
promising branch of livestock farming. Due to rabbits’
rapid maturation and high reproductive rate, it is
possible to obtain large quantities of dietary meat
—
especially valuable for children's nutrition
—
as well as
wool and high-quality fur products for industry, all
within a short period. Studying the influence of external
environmental conditions and housing factors on the
physiological state of rabbits during their maintenance
and care in experiments is of great scientific and
practical importance. Therefore, during the rearing of
young rabbits, identifying the factors affecting their
productivity
—
namely, adapting the organism to the
climatic conditions of a particular region and to existing
technological factors
—
serves as a guarantee for
increasing the amount and quality of the products
obtained from them.
On December 29, 2015, the First President of the
Republic of Uzbekistan adopted Presidential Decree
No. 2460. Furthermore, the “Program for Further
Reform and Development of Agriculture for 2016
–
2020” was approved by Presidential Resolution No. 03
-
36-12 dated January 21, 2016. In the section
“Development of Rabbit Breeding” of this program, it
was instructed to establish rabbit-breeding farms and
household-based farms in all regions of the republic.
Additionally, it was mandated to import meat and fur-
oriented rabbit breeds from foreign countries that are
suitable for the climatic conditions of Uzbekistan and to
develop scientifically based recommendations for
organizing breeding programs in newly established
rabbit-breeding farms.
Research Objective
The aim of the study is to examine the growth and
development of rabbits under the sharply changing
climatic conditions of Karakalpakstan when separated
from the nest at different ages.
METHODOLOGY
The dissertation research was conducted during 2021
–
2023 at the “Samandar Taxiatosh” Limited Liability
Company in the Takhiyatosh district of the Republic of
Karakalpakstan, using California breed rabbits raised
for meat production.
In the study, we examined the growth indicators of
rabbit kits born from mother rabbits and separated
from the nest at different ages (30, 45, and 60 days),
observing their development until the age of 75 days.
For this purpose, based on similarity criteria such as
origin, breed, age, and live weight, scientific research
was conducted according to the technological schedule
of separating rabbit kits from mother rabbits at 30, 45,
and 60 days of age. In 2021, Group I followed the
technology of separating kits from the nest at 30 days
of age; In 2022, Group II followed the technology of
separating them at 45 days of age; In 2023, Group III

followed the technology of separating kits at 60 days of
age. These studies were carried out using young rabbits
obtained from mother rabbits under standardized
conditions for each respective year and group.
The live weight of the rabbits was measured
individually using an electronic scale at birth and at 21,
30, 45, and 75 days of age, each time before the
morning feeding.
The collected data were processed biometrically using
the Ye.K. Merkureva method (1970) with the help of
Microsoft Excel 2010 software.
RESULTS
In animal husbandry practices, especially in meat
production, live weight is one of the most important
indicators of the growth and development of
agricultural animals. It is considered a key factor in
evaluating production efficiency.
In our study, we investigated the growth dynamics of
rabbit kits separated from the nest at 30 days (Group I),
45 days (Group II), and 60 days (Group III). The obtained
data are presented in Table 1.

Analysis of the data presented in Table 1 and Figure 1
showed that the live weight of rabbit kits in Group III,
which were separated from the nest at 60 days of age,
was 48.1 g at birth. This was respectively 2.7 g or 5.9%
(P<0.05) and 0.4 g or 0.8% higher compared to their
counterparts in Group I (separated at 30 days) and
Group II (separated at 45 days).

In the subsequent growth periods, the rabbit kits in
Group I (separated from the nest at 30 days) and Group
II (separated at 45 days) showed an advantage over
their counterparts in Group III (separated at 60 days).
Specifically, at 21 days of age, the live weight of rabbit
kits in Group I was 572.9 g. This was 36.0 g or 6.7%
higher (P<0.001) than those in Group II and 56.8 g or
11.0% higher (P<0.001) than those in Group III, whose
live weight was 516.1 g.
Furthermore, the rabbit kits in Group II (separated from
the nest at 45 days) had a live weight of 536.9 g at 21
days of age, which was 20.8 g or 4.0% (P<0.05) higher
than that of their counterparts in Group III (516.1 g),
separated at 60 days. At 30 days of age, the live weight
of rabbit kits in Group I (separated at 30 days) was
820.1 g. In comparison, the live weight of rabbit kits in
Group II was 794.2 g, which was 25.9 g or 3.3% higher
(P<0.001), and 68.5 g or 9.1% (P<0.001) higher than
that of Group III rabbits (751.6 g).
In addition, the live weight of rabbit kits in Group II was
42.5 g or 5.7% (P<0.001) greater than that of Group III,
showing a clear advantage in early growth.
The same tendency persisted in the later stages of the
growth period. Specifically, at 45 days of age, the
average live weight of rabbit kits in Group I was 1257.6
g, which was 54.9 g or 4.6% (P<0.001) and 59.2 g or
4.9% (P<0.001) higher than that of their counterparts in
Group II and Group III, respectively. Moreover, the live
weight of rabbit kits in Group II was 9.3 g or 0.8% higher
than that of the rabbit kits in Group III.
As a result of the study, it was found that at 60 days of
age, the live weight indicators of rabbit kits separated
from the nest at 30, 45, and 60 days remained
consistently higher in Group I during the subsequent
months of the growth and development period
compared to their counterparts in Groups II and III.
Specifically, at 60 days of age, the live weight of Group
I rabbit kits was 1899.2 g, which was 164.7 g or 9.5%
(P<0.001) and 274.4 g or 16.9% (P<0.001) higher than
that of rabbit kits in Group II and Group III, respectively.
Furthermore, the live weight of rabbit kits in Group II
exceeded that of Group III by 109.7 g or 6.8% (P<0.001).
At the end of the experiment, i.e., at 75 days of age, the
live weight of rabbit kits separated from the nest at 30,
45, and 60 days also remained highest in Group I
compared to Groups II and III. Specifically, the live
weight of rabbit kits in Group I was 2261.9 g, which was
161.7 g or 7.7% (P<0.001) and 291.2 g or 14.8%
(P<0.001) higher than that of kits in Groups II and III,
respectively. Moreover, the live weight of rabbit kits in
Group II exceeded that of Group III by 129.5 g or 6.6%
(P<0.01), showing a statistically significant advantage.
CONCLUSION
At the end of the experiment, i.e., at 75 days of age, the
rabbit kits separated from the nest at 30, 45, and 60
days showed that the live weight of Group I rabbit kits
remained higher than that of their counterparts in
Groups II and III.
Specifically, the live weight of Group I kits was 2261.9
g, which was 161.7 g or 7.7% (P<0.001) and 291.2 g or
14.8% (P<0.001) higher than the live weight of rabbit
kits in Groups II and III, respectively.
