In animal breeding, a species sex can influence the value of the animal. For example, in the horse breeding industry, mares are preferred as polo horses, while in wildlife breeding males with larger horns are more valuable. Therefore, the economic advantages of knowing the unborn fetus' sex are...

The division of the breed into different-quality groups, the creation and maintenance of the structure of the breed is the main goal of breeding along the lines, which ensures not only the preservation of the desired properties of animals of this breed, but also their further improvement. The...

The present equine genetic variation mirrors the deep influence of intensive breeding programs during the last 200 years. Here, we provide a comprehensive current state of knowledge on the trends and prospects on the variation in the equine male-specific region of the Y chromosome (MSY), which was...

The paper aimed to present an important part of genetic analysis in Romanian Trotter horse. The sample extracted from the population is represented by entire reproductive nucleus of Romanian Trotter breed from Dor Marunt studfarm. We analyzed the reproductive isolation and the age structure. The...

Factory breeds of horses are bred by the purebred method, which includes breeding by lines and families. Breeding by lines is the basis of zootechnical work with the breed, which includes the selection and choice of the best representatives of the line, planned for the transfer of valuable innate...

The main purpose of the warmblood horse breeds at present time is the use in the classical disciplines of equestrian sports (show jumping, dressage, eventing). But the selection for sport performance in horse breeding is associated with a number of difficulties: long generation interval, long...

This study aimed to collect some studies which focused on modern horse breeds' genetic origins and effects of domestication on horses. Domestication, the first step of using animals by humanity. Many variations are shaped modern animal species and breeds, also animal breeding techniques and...

The article provides an analysis of the current state of Kustanay breed of horses in the Northern region of Kazakhstan. More than 100 heads of breeding horses of Kustanay breed were recorded and described, incl. 9 breeders, 44 broodmare and 79 heads of young animals of different ages in three...

Background: Knowledge of the interdependence of characters, especially in terms of genetic correlation, is very important in the process of genetic improvement of domestic animal populations, as it is a basic condition in establishing the objective of selection. Methods: In this study, during...

Hungary has had a relatively large horse population over the centuries, the utilization of horses has been diverse, and their genetic stock is excellent. However, after World War II, the number of horses fell back to a fraction, and the horse breeding and equestrian sector was pushed into the...
