The formal Soviet coldblooded breeds were established through the improvement of the domestic horses with the Belgian and from them the selected crossbreds for further breeding. The Chernov stud farm also established a section of coldblooded horses for crossbreeding of draft horses with other draft breeds.
The Soviet draft horse has a medium dry head, muscular neck, well developed withers, wide, often soft back, well bounded loins, wide, split, often steep hind quarters, wide, medium depth of ribcage, well arched ribs, short, sufficiently dry legs (front is often “calf knee), dry joints, solid hoofs.
The constitution of the Soviet draft horse is solid, but rougher. In this breed there are several types. A type of heavy horses, to which belong horses of rougher constitution, lesser energy in movement, which resemble more the Belgian horse. The foundation type of these horses is a longer frame, massive, dry, solid body structure, with well-developed muscles, with lighter head, dry extremities, good movement and energetic temperament. The lighter type represents horses of dry body structure, but sufficiently massive, with rough head, smaller circumference of the chest/torso and lighter skeleton framework.
The common colors are: chestnut, dappled chestnut, light bay, or bay. The average sizes of stallions are: 160 cm, circumference of the chest 203 cm, of the shin bone 25 cm, and the weight of 900 kg and more. The mares’ measurements are: 150, 193, 23, 670 kg.
In the stud farms and the refining breeding stations are the Soviet draft horses bred in lineages. The most known is the line of Boze and Rumba.
