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.
