Nhanganyaya: National Spotted Saddle Horses
Mabhiza eNational Spotted Saddle Horses (NSSHs) imhando ine mukurumbira yemabhiza ane makumbo, anozivikanwa nemaitiro awo ejasi ane mavara akasiyana uye mafambiro akatsetseka. Yakagadzirwa muUnited States, NSSHs musanganiswa wemarudzi akati wandei, anosanganisira Tennessee Walking Horse, American Saddlebred, uye Missouri Fox Trotter. Ivo vanowanzo shandiswa kutasva nzira, kutasva mafaro, uye kuratidza.
Mhedziso yeGenetic Zvirwere muMabhiza
Kufanana nemhuka dzese, mabhiza anogona kutarisana nezvirwere zvemajini uye kusagadzikana. Mamiriro ezvinhu aya anokonzerwa nekushanduka kana kusiyanisa muDNA yebhiza, iyo inogona kukanganisa mabasa akasiyana-siyana emuviri. Zvimwe zvirwere zvema<em>genetic zvakapfava, nepo zvimwe zvingava zvakakomba kana kutouraya. Zvakakosha kuti vapfuri vemabhiza nevaridzi vazive nezvezvirwere zvemajini zvinogona kukanganisa mhuka dzavo, pamwe nemaitiro akanakisa ekudzivirira nekugadzirisa mamiriro aya.
Genetic Disorders Inowanikwa muSpotted Breeds
Zvinetso zvinoverengeka zvemajini zvinowanzoitika mumabhiza ane mavara ejasi mapatani, kusanganisira maNSSH. Mamiriro aya anogona kusanganisira kukanganiswa kweganda, matambudziko ekuona, uye kusagadzikana kwetsandanyama. Zvimwe zvezvirwere zvinonyanya kuzivikanwa zvemajini mumabhiza ane mavara zvinosanganisira Hereditary Equine Regional Dermal Asthenia (HERDA), Polysaccharide Storage Myopathy (PSSM), Recurrent Exertional Rhabdomyolysis (RER), Equine Hyperkalemic Periodic Paralysis (HYPP), Congenital Stationary Night Blindness (CSNB) ), uye Lavender Foal Syndrome (LFS).
Kuwanda kweGenetic Diseases muNSSHs
Nepo maNSSH asinganyanyi kubatwa nezvirwere zvemajini pane mamwe mabhiza, anogona kunge ari panjodzi huru kune mamwe mamiriro nekuda kweiyo genetic maitiro. Semuyenzaniso, maNSSH anogona kunge achigadzira PSSM, mamiriro ezvinhu anokanganisa mashandisiro anoita tsandanyama dzebhiza nekuchengeta simba. Zvakadaro, kuwanda kwezvirwere zvemajini muNSSH kunosiyana zvichienderana nebhiza rega rega uye nhoroondo yekuzvara kwaro.
Hereditary Equine Regional Dermal Asthenia (HERDA)
HERDA chirwere cheganda chinokanganisa mamwe mabhiza, kusanganisira maNSSH. Chirwere ichi chinoita kuti ganda rebhiza riite zinyekenyeke uye rinoda kubvaruka uye kuva nemavanga. HERDA inokonzerwa nekuchinja kweiyo PPIB gene, iyo inokonzera kubudisa puroteni inobatsira kusimbisa ganda. Iko hakuna mushonga weHERDA, uye mabhiza akabatwa angada kutarisirwa kwakakosha kudzivirira kukuvara.
Polysaccharide Storage Myopathy (PSSM)
PSSM chirwere chemhasuru chinokanganisa mamwe mabhiza, kusanganisira maNSSH. Chirwere ichi chinoita kuti tsandanyama dzebhiza dzichengete glycogen yakawandisa, rudzi rwecarbohydrate inoshandiswa kuita simba. Nokufamba kwenguva, izvi zvinogona kutungamirira kukukuvara kwemhasuru uye kushaya simba. PSSM inokonzerwa ne genetic mutation inobata mabatiro anoita tsandanyama dzebhiza metabolize simba. Iko hakuna mushonga wePSSM, asi mabhiza akabatwa anogona kutarisirwa kuburikidza nekudya uye kurovedza muviri shanduko.
Recurrent Exertional Rhabdomyolysis (RER)
RER chirwere chetsandanyama chinokanganisa mamwe mabhiza, kusanganisira maNSSH. Chirwere ichi chinoita kuti tsandanyama dzebhiza dzityoke mushure mekuita maekisesaizi, zvichikonzera kuoma, kurwadza, uye kutadza kufamba. RER inokonzerwa nekushanduka kwemajini kunokanganisa kuti tsandanyama dzebhiza dzinoburitsa sei calcium, chinhu chakakosha chemusuru kuputika. Iko hakuna mushonga weRER, asi mabhiza akabatwa anogona kutarisirwa kuburikidza nekudya uye kurovedza muviri shanduko.
Equine Hyperkalemic Periodic Paralysis (HYPP)
HYPP chirwere chemhasuru chinokanganisa mamwe mabhiza, kusanganisira maNSSH. Chirwere ichi chinokonzeresa zvikamu zvetsandanyama kudedera, kupera simba, uye kudonha. HYPP inokonzerwa neiyo genetic mutation inokanganisa kuti tsandanyama dzebhiza dzinogadzirisa sei potassium ions. Iko hakuna mushonga weHYPP, asi mabhiza akabatwa anogona kutarisirwa kuburikidza nekudya uye shanduko yemishonga.
Congenital Stationary Night Blindness (CSNB)
CSNB idambudziko rekuona rinobata mamwe mabhiza, kusanganisira maNSSH. Chirwere ichi chinoita kuti bhiza riomerwe nekuona muchiedza chakaderera, uye zvinogona kutungamirira kuupofu hwehusiku. CSNB inokonzerwa ne genetic mutation inobata kuti retina yebhiza inopindura sei chiedza. Iko hakuna mushonga weCSNB, asi mabhiza akakanganisika anogona kutarisirwa kuburikidza nekuchinja kwezvakatipoteredza uye kudzidziswa kwakasarudzika.
Lavender Foal Syndrome (LFS)
LFS idambudziko risingawanzo genetic rinobata mamwe mabhiza, kusanganisira maNSSH. Ichi chirwere chinoita kuti bhachi rebhiza rishandure ruvara rwelavender, uye zvinogona kukonzera matambudziko etsinga. LFS inokonzerwa nekuchinja kwemajini kunokanganisa kuti masero ebhiza anobudisa sei mamwe ma enzymes. Iko hakuna mushonga weLFS, uye vana vakabatwa vanogona kusararama.
Mhedziso: NSSHs uye Genetic Zvirwere
Nepo maNSSH ari rudzi rwunodiwa rwemabhiza anomhanya, anogona kunge ari nyore kune dzimwe zvirwere zvemajini uye kusagadzikana. Zvakakosha kuti vapfuri vemabhiza nevaridzi vazive nezvemamiriro ezvinhu aya, uye kutora matanho ekudzivirira nekugadzirisa. Nekushanda nevarapi vezvipfuyo nemasangano ekupfuya mhuka, varidzi veNSSH vanogona kubatsira kuona hutano nekugara zvakanaka kwezvipfuwo zvavo.
Kudzivirira Zvirwere zveGenetic muNSSHs
Nzira yakanakisa yekudzivirira zvirwere zvemajini muNSSH ndeyekungwarira maitiro ekurera. Vapfuri vemabhiza vanofanirwa kuitisa genetic test pane yavo yekuberekesa kuti vaone chero vangango takura genetic mutations. Vanofanirwawo kudzivirira kupfuya mabhiza ane anozivikanwa genetic kusagadzikana, uye kuyedza kuchengetedza akasiyana uye ane hutano gene dziva. Varidzi vemabhiza vanogonawo kubatsira kudzivirira zvirwere zvemajini nekupa mhuka dzavo kutarisirwa kwakanaka uye kudya kunovaka muviri, uye nekushanda nevarapi vemhuka kuti vatarise hutano hwebhiza ravo.
