- Exam within the exam period which consists of two (practical

and theoretical) parts. At first, students are controlled by a

questionnaire on computer (according to their rapid answers

to basic figures, breeds, tools, wool samples and age

determination, http://gat.univet.hu/hu/node/2189) as a

threshold to enter into the theoretical part. The performance

from 60% is successful.

And then, they choose four questions, and after a preparation

time they answer these orally. All the four questions should

be answered (a single unknown question leads to failure). All

questions are published in advance. In case of failed exam,

students with at least 80% performance in computer test do

not need to repeat the practical part. Time span between the

exam failed and its re-take should exceed 5 days.-

Exam: Eighty questions in oral part:

– many transitional species: Eohippus →Mesohippus →Miohippus →Merychippus →Pliohippus →Equus.– cca. 60 million years long process.– major changes: body size, nutrition (omnivorous for herbivorous), tooth, reduction of digits, life mode.

Zoological position and taxonomy of the horse

(chromosome numbers)• Phylum Chordata

• Class Mammalia

• Order Perissodactylia (non-ruminant hoofed mammals,

horse, tapir, rhinoceros)

• Family Equidae – Subgenus Equus (horses, species: Equus ferus Boddaert)

• Equus ferus Przewalskii-taki (2n = 66),

• Tarpan (Equus ferus ferus, silvaticus, Forest Horse, germanicus extinct, 2n = ?), extinct

• Equus caballus (domesticated horse, 2n = 64)

– Subgenus Asinus (African ass,): Species:

• Equus asinus/africanus (Nubian and Somali wild ass, chrm. No: 62)

• Domiesticated ass (donkey, Equus africanus, chrm. No: 62)

Horse Genome Project (http://www.uky.edu/Ag/Horsemap/)

• First genome sequenced: Twilight English Thoroughbred mare (Cornell University in Ithaca, N.Y.) (Chowdhary BP, Raudsepp T. The horse genome, Genome Dyn., 2006. 2:97-110.)

• Size: 2.7 billion DNA base pairs.

• First gene map for studying (2006) equine genetic diseases.

• 1 million base mutations: single nucleotide polymorphisms (point mutation, SNP).

• About 80 genetic diseases are comparable to human genetic disorders.

• SNP-s (point mutations) are available: www.broad.mit.edu/mammals/horse/snp or NCBI Single Nucleotide Polymorphism database, dbSNP (www.ncbi.nlm.nih.gov/SNP).

Interspecies-hybridization of equines

Hybridization is possible:

Wild horse (Taki, 2n = 66) ×domestic horse (2n = 64 -fusion);

Domestic horse (2n = 64) ×domestic ass (2n = 62);

Domestic horse (2n = 64) ×Zebra (2n = 62);

Zebra (2n = 62) × domestic ass (2n = 62).

Unfertile offspring!

Used: Mule, hinnies.

Merits: heterosis, power, working, stamina, obedience, heat tolerant, disease resistant.

Przewalski-horse (Taki)

Domestic horse (2n =

64) × domestic ass

(2n = 62);

mulus, mule

hinnus, hinny

Haldane rule:Heterogametic gender is sterile

Zebra (2n = 62) × domestic ass (2n = 62).(zonkey, zedonk, zebrass).

Domestic horse (2n = 64) × Zebra (2n = 62)(mare, horse, 2007)

zorse

Inter-species hybridization of equines - fertility

Wild horse (Przewalski-horse) × domestic horses: successful,fertile offspring;

Horse (domestic, wild) × ass (donkey): successful, not fertile, except rarely the mares;

mule (horse mare),

hinny (she-ass);

Horse × zebras: not fertile (zorses);

Asses × zebras: not fertile (zonkeys, zedonk, zebrass)

Portmanteau words!

Haldane’s rule: primarily the heterogametic sex (male!) is affected by sterility in successful crossing of closely related species.

Heterosis: inter-specific hybrids may show higher strength, endurance, tolerance and resistance to heat and diseases (mainly mules).

Biotechnology!Hunting of horses from BC 30 000

Domestication of the horse

• Domestication 5-6000 years ago: Central Asia, Persia, Egypt, Europe, to America arrived only after 1492 (by Spanish invaders).

• Historical use of horse: hunting, chariot, carriage, coach, people migration, transport, military use, agriculture, races, sport, hobby, leisure, therapy, recreation, status-symbol…etc.

• Major role in cultural and social development of mankind!

• Ancestors, wild horses:

– Living to date: Przewalski-horse or taki, Mongolian steppes.

– Extinct: Tarpan, West-European, Forest horse.

– Returned to nature: feral horses, Mustang, Bramby - re-domestication possible.

– Features: dun, cream-, grey-coloured, black ridge, eel stripe, standing mane, „missing withers", cross at withers, zebroid stripes on legs, 125-130 cm withers height.

Wild horses:

(1) „Tarpan” from zoos

(Reconstruction as Heck-Horse)

(2) Przewalski-horse (Mongolian

Taki)

Wild horse features: bay dun,

rarely mouse dun, eel stripe

(dorsal line), standing mane,

zebra stripes, height at withers:

125-130 cm

Wild colours of the domestic horseMost important genetic consequences of horse

domestication

• 2n chromosome number: fusion of

chromosomes?

– Wild and domestic horse: 66→64, presumption only, not

proved.

– Tarpan (?) is unknown (extinct).

– Ass remained the same: 62.

• New mutations and artificial selection:

– Many new mutations (harmful – genetic diseases,

favourable, desired) → high allelic polymorphism on the

same locus across breeds.

– Diversity has increased (in size, type and colour).

– More then 200 breeds, breed groups and types

(Falabella, Shire, Ponies, Brabant etc).

Most important phenotype consequences of horse

domestication

• Diversity seen in:– Varied sizes, body builds (heights 50-180 cm), dwarfism;

– Weights (50-1200 kg), heavy, light horses and ponies;

– Many colour variants, temperament, long hair disappeared;

– Less effective feed conversion;

– Accelerated ageing;

– Sensitivity to respiratory diseases, decreased resistance;

– Not well expressed sex dimorphism;

– Sexual activity changed from mono-estrus to seasonal poly-estrus;

– Ability to return to the nature (feral horses, America –Mustang, Australia – Brumby).

Horses show more, asses less diversity and domestication

changes.

Biological characteristics of horse

• Herbivorous, can not ruminate and vomit.

• Odd-toed.

• Loving a group.

• Uniparous.

• Short and long hairs, shedding.

• Vivid, scary, but trainable.

• Escaping lifestyle (frequent ingestion and suckling).

• Large framed.

• Long time periods (slow genetic improvement).

• Dicromatic vision.

Terminology (various sexes, age and life cycle)

• Foal: less than one year old of either sex; nursing foal, suckling, weanling (at 4-6 months of age).

• Yearling: between one and two years.

• Colt: male under the age of four; common error: to call any young horse a colt.

• Filly: female horse under the age of four.

• Mare: female horse four years old and older, brood-mare.

• Stallion: stud, non-castrated male horse four years old and older. A "rig" is a stallion having undescended testicle.

• Gelding: castrated male horse of any age.

• She-ass: jennet,

• He-ass: jack

Horses to distinguish

• Wild horse: the only living species: Equus ferus

Przewalski (taki).

• Domesticated horses: horse breeds and types.

• Feral horses: free-roaming

horses of domesticated ancestry, often are

popularly called as "wild" horses. Feral horses

live in groups called a band, herd, harem, or mob.

• Semiferal horses: live in a feral condition but

may be occasionally handled or managed by

humans.

Most common feral horses

• Mustang: Europeans (Conquistadors)

reintroduced the horse to the American Continent in

the 15th century, some horses escaped and

formed feral herds known today as Mustangs.

• Brumby: Australia has the largest population of

feral horses in the world (400,000). The Australian

name is the Brumby, feral descendants of horses

brought to Australia by English settlers.

• In Portugal, there are two populations of free-

ranging feral horses, known as Sorraia in the

southern plains and Garrano in the northern

mountain chains.

• There are also isolated populations of feral horses

in a number of other places (Islands of Nova

Scotia, of Virginia and Maryland, of Georgia etc).

Mustang, mestena, the „wild horse” of America (in USA gene
