EVALUATION OF WORKING QUALITIES OF ORLOV TROTTER BREED HORSES OF DIFFERENT ORIGIN AND RESULTS OF THEIR TESTS IN THE CONDITIONS OF THE BRANCH “ODESSA HIPPODROME” SE ‘HORSE BREEDING OF UKRAINE’

Abstract

The current state of the breeding stock of Orlov trotters in Ukraine is studied and analyzed in the work. During the research of selection methods in farms of different forms of ownership it was found that the optimal method of breeding horses is cross lines, and crossing Orlov trotting breed with purebred riding breed does not significantly increase the liveliness and prize precocity of horses. In the Orlov trotter breed, the best indicators of liveliness belong to the offspring obtained as a result of complex inbreeding on such outstanding breeders as Pion, Fagot, Viter, Otklik, Pozyv. The crosses of the lines Barchuk × Pilot, Barchuk × Boltik, Ispolnitelny × Boltik turned out to be the most successful. The predominant number of descendants of class 2.05 was received from the stallions Prikaz (5 heads) and Otklik (4 heads). Promising lines in the reproductive composition of Orlov trotters of Ukraine are the lines of Barchuk, Pion and Pilot. Representatives of the Dibrivsky horse factory are characterized by the best indicators of an exterior. Over the past 10 years, 7 records of the hippodrome have been set at the Odessa Hippodrome by horses of the Orlov trotter breed, 4 of which belong to the fosterlings of the Zaporizhia Horse Farm. The most progressive in terms of the number of victories in both traditional and ordinary prizes is Barchuk's line, the purposeful work of which has been carried out at the Zaporizhia Horse Plant for many years.
