This paper initiates the implementation of the BLUP methodology for assessing the breeding
value of pigs in the conditions of domestic pig farming in Kazakhstan. The initial data analysis
revealed several critical problems that hinder the correct implementation of statistical calculations.
The main issues are the high percentage of missing values and abnormal data in key parameters, such
as litter weight, number of piglets, and measurement dates. These shortcomings lead to the
impossibility of using a significant part of the records to calculate the complex index using the BLUP
method. The paper proposes a comprehensive interdisciplinary approach, including identifying
influencing factors based on international experience and regional characteristics, improving the data
collection and control system in the information and analytical system (IAS), and developing
specialized software. The study results demonstrate that even with correct management of
identification data, significant problems remain that require further refinement of the algorithms for
cleaning and quality control of the initial data, which must be considered in the subsequent practical
implementation of the methodology. Applying the developed method will improve the accuracy of
assessing the breeding value of pigs and, in the long term, improve the efficiency of breeding work in
the industry.
