GENETIC AND ENVIRONMENTAL PARAMETERS IN TROTTERS RACING PERFOMANCE EVALUATION

Abstract

Breeding goal and selection measures in breeding of trotter horses are subjected to horses production with the fastest possible speed in trotting. Evaluation of racing horses’ performances is important because of horse impact on horse industry. More valuable horses and larger prizing fond result in a higher attendance of hippodromes and more money paid in betting offices. Race horse industry notes a large number of data used in predictions during breeding of horses with better racing performances every year. Racing performances are affected by a large number of genetic and environmental (non-genetic) factors caused by different environmental effects. Therefore, they are more variable. The major genetic and environmental parameters used in the models of breeding values racehorses in this case trotters are reviewed in this paper.
