About the breed
The Slovenian Cold-blood is a native Slovenian breed of heavy but medium-framed draught horses that took shape in north-eastern Slovenia and Upper Carniola (Gorenjska) and is now kept throughout the country. It is Slovenia's most widespread horse breed: according to older Slovenian Gene Bank data it accounts for around 27% of all horses there. The breeding goal describes a harmonious, sturdy and noble cold-blood of medium frame, with a good-natured character and a calm temperament, suited to harness work but also to riding.
From Bohinj and Međimurje horses to a modern breed
The Slovenian Cold-blood grew out of several local cold-blooded populations that no longer exist: the Gene Bank lists the Posavinje, Bohinj, Kobarid, Međimurje and Alpine horses, which were improved with Belgian and Noriker stallions under the Austro-Hungarian monarchy. According to the 2010 breeding programme (Slovenian Cold-blood breeders' association and Veterinary Faculty, Ljubljana), the original population in western Slovenia was essentially of Noriker descent until 1918, and that in the north-east of Međimurje descent. Between the world wars Noriker and Percheron stallions were used, and from 1940 to 1945 only Noriker stallions anywhere in Slovenia. According to a master's thesis from the Biotechnical Faculty, the breed's present name dates from 1964. A breeding programme was adopted in 2005, when the breeders' association was also founded, and the programme in force dates from 2010 (confirmed on 13 December 2010 according to the Gene Bank register).
Noriker blood and stallion lines
The Noriker has strongly influenced the Slovenian Cold-blood, yet the two are separate breeds with separate studbooks. The breeding programme states that, because of the Noriker's strong influence since 1918, the stallion lines trace back to Noriker ancestors, and only one line was founded by a stallion of Croatian, Belgian-Međimurje origin. The 2010 programme divides 179 breeding stallions into the lines Nero (63), Vulkan (52), Schaunitz (24), Diamant (20), Elmar (9) and Zvezdan-Gölle (7), plus four other stallions of Noriker descent. Since 2006 only individual selected Noriker stallions may be entered in the studbook to refresh the blood.
Height at the withers, weight and build
The Slovenian Cold-blood generally stands 146 to 160 cm at the withers. The breeding programme gives an average of 155 cm for stallions (range 148–160 cm) and 150 cm for mares (146–158 cm). An analysis of 1,920 horses assessed between 1996 and 2011 (Simčič and colleagues, 2015) found averages of 152.4 cm in stallions and 151.2 cm in mares; body length exceeded withers height, giving these horses a rectangular frame.
The studbook does not set a weight. A 2016 master's thesis from the Biotechnical Faculty gives an average body mass of about 550–650 kg, without naming a measurement source, and the Gene Bank adds that larger horses in good condition can exceed one tonne. Breeders in the lowlands favour large, heavy horses, while those in hilly areas prefer robust but shorter animals. The breeding goal calls for a fairly large, dry head with a straight to moderately convex profile, a well-muscled neck, a long, broad and deep body, a split croup and sturdy, clean legs with hard hooves.
Colours: all except pinto
The breeding goal in the programme lists all colours except pinto (patched) horses, with as few white markings as possible. The Gene Bank's booklet says all coat colours are present except pinto, with bays, chestnuts and blacks predominating. Chestnuts are therefore among the listed colours, while pinto horses are not part of the breeding goal.
The Međimurje type in the 2010 breeding programme
The 2010 breeding programme provides for a stallion book and a mare book of the Međimurje type for part of the population in the Lenart, Ormož, Ptuj and Ljutomer districts and all of Prekmurje; with this the breeders' association, according to the programme, joins the ERFP project "Saving the murinsulaner breed", which aims to reconstruct the Međimurje horse. The programme describes this type as somewhat lighter, with clean, less robust limbs and a livelier temperament; its table gives 147–153 cm at the withers for stallions and 146–153 cm for mares (alongside a further 155–156 cm that it does not explain), and the intended colours are chestnut, bay and black. In a Biotechnical Faculty study (Potočnik and colleagues, 2011), 47% of 41 measured mares of this type were bay, 40% black and 10% chestnut. Sources differ on the status: the Slovenian Gene Bank and the Slovenian entry in FAO DAD-IS count the Međimurje horse among the extinct breeds from which the Slovenian Cold-blood was formed (a separate Slovenian DAD-IS record for the Međimurje horse likewise lists it as extinct), whereas in Croatia, according to that 2011 study, the Međimurje horse is registered as a separate native breed (see the Međimurje Horse profile).
Slovenian Cold-blood, Noriker or Posavina Horse: what is the difference?
The Slovenian Cold-blood differs from the Noriker in studbook, size and colour. The Salzburg studbook of origin gives the Noriker ideal heights of 156–164 cm for mares and 160–165 cm for mature stallions, taller than the Slovenian averages of 150 and 155 cm; a Noriker may also be leopard-spotted or pinto, whereas the Slovenian breeding goal allows every colour except pinto. The Posavina Horse (Posavac), Slovenia's other native cold-blood, has a smaller frame: the Slovenian breeding programme gives 148 cm (145–152 cm) for stallions and 143 cm (135–148 cm) for mares.
Temperament: good-natured, calm and willing
The breeding goal asks for a good-natured character and a calm temperament, and the Gene Bank stresses its perseverance and willingness to work. Its booklet adds that the breed is less demanding to school and that the horses quickly accept work under saddle and in harness. In the working-ability test, which is compulsory for stallions licensed without restriction, a panel scores obedience, willingness and ability, and working technique. Individual horses still vary with breeding, experience and schooling.
Is the Slovenian Cold-blood suitable for beginners and children?
A calm, well-schooled Slovenian Cold-blood can suit a less experienced person, but ideally with guidance from an experienced instructor or breeder. Its calm temperament helps, yet its sheer mass means a clumsy step can land on a foot or pin someone against a wall. As the Gene Bank notes that leisure horses of this breed are used mainly in harness and less often under saddle, it is worth checking what an individual horse already knows before buying. With so large an animal, children are normally supervised by an adult; according to the Gene Bank, a large share of these horses can be trained for equine-assisted therapy.
Uses: driving, farm work, forestry and tourism
Today the Slovenian Cold-blood is bred mainly for meat, but it also works in harness, on farms and in forests, and in tourism. The Gene Bank states that a large part of the population is raised for slaughter foals and that the breed is also suited to mare's milk production. Some breeders still use their horses for farm tasks and, to a lesser extent, for hauling timber. Stallions' working ability is checked in a test covering harnessing, log pulling and work in single harness; a horse passes with 70% of the maximum score.
Grazing, hay and equine company
Grazing and hay form the basis of the Slovenian Cold-blood's diet; the Gene Bank notes that the breed makes good use of forage. The breeding programme recommends all-day grazing in the grazing season, ideally on upland pastures, and husbandry that allows species-appropriate socialisation. The DEFRA Code of Practice for the Welfare of Horses recommends almost constant access to forage (grass, hay, haylage) outside working hours, continuous access to clean water and regular monitoring of body condition; there are no universal quantities. The code adds that supplementary feed, vitamins and minerals may be needed if grazing is inadequate, and that concentrates should be no more than the energy needed for the exercise performed or for any required weight gain. Because horses are herd animals, the code says isolating a horse from other horses can have a negative psychological impact, and stabled horses benefit from daily turnout.
Care: hooves, teeth and routine health care
Care of a Slovenian Cold-blood has to be regular; a Biotechnical Faculty master's thesis, citing older sources, says these horses are somewhat more demanding to keep and less hardy than similar breeds. The mane and tail need combing, the coat should be cleaned before and after work, and the hooves checked regularly. The DEFRA code says hooves should usually be trimmed or re-shod by the farrier every 4 to 8 weeks, and teeth checked at least once a year by a vet or qualified equine dental technician. According to the code, infectious disease should be controlled through a programme agreed with a vet that includes hygiene, isolation procedures and vaccination, and a parasite-control programme should be put in place after consulting a vet or another suitably qualified person, using faecal worm egg counts and wormers only when necessary.
Health and lifespan
There is no published breed-specific lifespan for the Slovenian Cold-blood; the Merck Veterinary Manual gives 25 to 30 years for horses in general, depending on health, care and size. A horse with a hernia, dental faults, cryptorchidism, extensive skin or iris depigmentation, chronic obstructive bronchitis or summer eczema cannot be entered in the studbook; this does not mean these problems are common, only that selection excludes them. We found no published data on hereditary diseases specific to this breed. The Merck manual notes that the muscle disease PSSM1 is frequently seen in draught horses and can be diagnosed with a genetic test. Because the Noriker has strongly influenced the breed, an Austrian study (Druml et al. 2017) is worth noting: it found 34% of 517 mature Noriker breeding horses to carry the GYS1 mutation linked to PSSM1; we found no comparable estimate for the Slovenian breed.
According to an older Gene Bank page, the breed is classed as critically endangered because of relatively high relatedness between horses. In the risk assessment in the Gene Bank register the breed is rated "critical" at national level (2025), likewise for its inbreeding rate, and "endangered" for reproductive capacity and population trend; FAO DAD-IS lists it as endangered. In 2025 there were an estimated 3,358 purebred horses, with 1,217 breeding mares and 131 stallions in the studbook; to prevent mating between relatives, the breeding programme calls for controlled mating.
Who the Slovenian Cold-blood suits – and who it suits less
The Slovenian Cold-blood suits driving enthusiasts, breeders who want to preserve a native breed, farms with enough pasture, and people looking for a calm horse for leisure and light work. It is less suited to riders who want a sport horse for show jumping or dressage, and to owners without pasture or a sturdy stable. It needs daily exercise, other horses for company, good hay or grazing, regular farrier visits, dental checks, and a vaccination and parasite-control programme agreed with a vet. Keeping a running record of vaccinations, farrier visits and dental checks makes that care easier to follow.
