Linebreeding as a system of stock breeding to improve the productive qualities of horses of the Kushum breed.
Abstract: Possessing high meat and dairy productivity and good reproductive and adaptive qualities to year-round grazing, the Kushum breed plays an exceptional role in the improvement of productive qualities in horse herding in Kazakhstan and the former Soviet republics. The aim of the study was to develop breeding methods for creating new highly productive breeding lines for the Kushum breed horses. The leading method was linebreeding, which is based on the systematic use of remarkable animals, the offspring of which will accumulate and develop all the desired qualities and traits. The practical significance of the study lies in the fact that new highly productive breeding lines of the Kushum horse have been created. On this basis, a new intra-breed type of horses with increased live weight, high productivity and adaptive qualities for winter grazing in the Republic of Kazakhstan was created. The results of the study were introduced in farms engaged in breeding Kushum horses. Highly productive stallions of the Kushum breed of new genotypes are sold in horse breeding farms of the republic. These studies are used in the development of a comprehensive plan for selection and breeding work and a scientifically grounded system for conducting productive horse breeding in the Republic of Kazakhstan. The scientific novelty of the study lies in the creation of new highly productive breeding lines of stallions of the Kushum breed Krepysh and Grom, as well as in substantiating the creation of the Samotsvet line with high adaptive qualities.

Summary

The research study focuses on the enhancement of the Kushum breed of horses by applying a systematic breeding method called linebreeding. The goal is to amplify the productive qualities including meat and dairy productivity of the horse breed, eventually leading to the creation of highly efficient lines within the breed.
Objective of the Study
- The main objective of the research was centered on devising methods for breeding to generate new, more productive breeding lines for Kushum horses. By focusing on remarkable specimens within the breed, the aim was to accumulate and enhance the desired qualities and traits across generations using linebreeding.
Methods Used
- Linebreeding was the chief strategy used in the study. This type of breeding involves mating related individuals that share a common ancestor. Through this approach, the goal was to concentrate desirable traits from remarkable animals within the breed. The anticipation was that their offspring would then exhibit these enhanced traits.
Results and Practical Implications
- The research proved to be impactful as it resulted in the creation of new highly productive breeding lines within the Kushum horse breed. This, in turn, led to the formation of a new intra-breed type of horses that have a higher live weight and superior productivity, making them more adaptive to year-round grazing, particularly winter grazing in Kazakhstan.
- The outcomes of the research have been implemented in real-world scenarios within the republic. The new and highly productive genotypes of the Kushum horse breed have gained acceptance in the horse breeding farms, elevating the quality of horse breeding in the country.
Scientific Contributions
- The study has contributed significantly to the scientific community with the creation of the new breeding lines of Kushum breed stallions, Krepysh and Grom, which showcase improved productivity.
- Another novel aspect of the research includes the genesis of the Samotsvet line, engineered for higher adaptability, reinforcing the advancement in the genetics of horse breeding.
- The outcomes from these studies will play a key role in developing a comprehensive plan for breeding work and forming a scientifically justified system for productive horse breeding in Kazakhstan.
