Abstract
The Friesian horse population has a higher than generally accepted level of inbreeding. Congenital disorders such as hydrocephalus and dwarfism occur in a higher prevalence than other breeds of horses, widely accepted to be a consequence of this inbreeding. The most common cause of hydrocephalus in Friesian horses is stenosis of the jugular foramen due to a mutation in the B3GALNT2 gene. This mutation is carried by approximately 10% of stallions and 17% of mares. Dwarfism in Friesian horses has a prevalence of 0.25% and is caused by a mutation on the B4GALT7 gene. Foals born affected by this disease are smaller than unaffected horses and have very lax flexor tendons. This mutation gives rise to the possibility of a ‘pony type’ Friesian, however ethics and welfare of breeding for such characteristics need to be considered. Friesian mares are at risk of retained foetal membranes 54% of the time. Owners and vets must be quick to act and treat this complication correctly to prevent further complications and protect the health of the mare. Current recommended therapy includes uterine lavages and oxytocin. Friesian stallions undergo rigorous testing to be accepted into the studbook and 50% of them are rejected. Younger stallions have poorer quality semen than older ones and inbreeding does not influence semen quality in Friesian horses. There is contradicting data from studies in other breeds regarding inbreeding effects on semen quality, so more research is required.
Abstract (croatian)
Populacija frizijskih konja ima višu razinu parenja u srodstvu od one općeprihvaćene. Urođeni poremećaji poput hidrocefalusa i patuljastog rasta javljaju se u većoj prevalenciji nego kod drugih pasmina konja, a široko je prihvaćeno da su posljedica navedenog parenja u srodstvu. Najčešći uzrok hidrocefalusa kod frizijskih konja je stenoza jugularnog otvora zbog mutacije na genu B3GALNT2. Ovu mutaciju nosi otprilike 10% pastuha i 17% kobila. Patuljasti rast kod frizijskih konja ima prevalenciju od 0,25% i uzrokovan je mutacijom na genu B4GALT7. Ždrebad koja je rođena s ovom bolešću manja je od nezaraženih konja i imaju vrlo slabe tetive fleksora. Ova mutacija dovodi do mogućnosti stvaranja frizijske pasmine u „tipu ponija“, međutim potrebno je uzeti u obzir etiku i dobrobit uzgoja za takve karakteristike. Frizijske kobile su u 54% slučajeva izložene riziku od zadržavanja plodnih ovoja. Vlasnici i veterinari moraju brzo djelovati i pravilno liječiti ovu komplikaciju kako bi spriječili daljnje komplikacije i zaštitili zdravlje kobile. Trenutno preporučena terapija uključuje ispiranje maternice i oksitocin. Frizijski pastusi podvrgavaju se rigoroznom testiranju kako bi bili primljeni u matičnu knjigu pastuha i 50% njih biva odbijeno. Mlađi pastusi imaju lošiju kvalitetu sjemena od starijih i srodstvo ne utječe na kvalitetu sjemena frizijskog konja. Postoje kontradiktorni podaci iz studija na drugim pasminama u vezi s učincima parenja u srodstvu na kvalitetu sjemena, pa su potrebna daljnja istraživanja.
