Iintlobo zeenkukhu ezizalela amaqanda zorhwebo.

Ziziphi iintlobo zeenkukhu ezizalela amaqanda zorhwebo?

 Ngokwemibala yeqokobhe leqanda, iintlobo zorhwebo zanamhlanjeiinkukhu ezibeka amaqandazahlulwe kakhulu kwezi ntlobo zilandelayo zintathu.

 (1) Iinkukhu zanamhlanje ezineqokobhe elimhlophe zonke zivela kwiintlobo zeLeghorn ezimhlophe ezine-crowned single-crowned, kwaye iinkukhu ezixutyiweyo zorhwebo ezizalayo ezinemigca emibini, ezintathu okanye ezinemigca emine ziveliswa ngokuzalanisa ii-imigca ezahlukeneyo ezicocekileyo.

Ngokwesiqhelo, i-sex-linked feathering gene isetyenziselwa ukwahlula amantshontsho angamaduna namabhinqa kwisizukulwana sorhwebo. Le nkukhu ifanelekile kulawulo olunzulu lwekheji.

Iindidi eziqhelekileyo zeenkukhu ezineqokobhe elimhlophe eziveliswayo ziquka iXingza 288, iBabcock B300, iHyland W36, iHyland W98, iRoman White, iDeca White, iNick White, iJingbai 938, njl.

 (2) Umaleko weqokobhe elimdaka usebenzisa kakhulu i-gene yombala weentsiba ezidityaniswe ngokwesini ukuze kuphunyezwe ukwahlulwa kwamantshontsho kwinkunzi nakwimazi.

Eyona ndlela ibalulekileyo yokufanisa kukusebenzisa iLuodao Red Chicken (enomlinganiselo omncinci weNew Hanxia Chicken bloodline) njengomgca wendoda, kunye neLuodao White Chicken okanye iBailuoke Chicken kunye nezinye iintlobo ezineejini zesilivere ezihamba nazo njengomgca wendoda. Xa kusetyenziswa ijini ethe tyaba njengezahlulo, inkukhu ebomvu yeLuodao okanye ezinye iintlobo zenkukhu ezingenamabala anqamlezileyo (ezifana nenkukhu emnyama yase-Australia) zisetyenziswa njengomgca wendoda, kwaye inkukhu yeRock enebala elithe tyaba isetyenziswa njengomgca wendoda wokufanisa ukuvelisa amaqanda enkukhu emdaka. Iindidi eziqhelekileyo zeenkukhu ezineegobolondo ezimdaka eziveliswayo ziquka iHyland brown, iRoman brown, iIsa, iHessex brown, iNick red njalo njalo.

 (3) Iinkukhu ezizalayo ezinombala omdaka okhanyayo (okanye iqokobhe elipinki) ziintlobo zeenkukhu eziveliswa ngokudityaniswa kweenkukhu ezimhlophe ezikhanyayo kunye neqokobhe eliphakathi elimdaka ophakathiiinkukhu ezibeka amaqanda, ngoko ke zisetyenziswa njengeentlobo eziqhelekileyo zeenkukhu zanamhlanje ezibeka amaqanda amhlophe kunye neenkukhu ezibeka amaqanda amdaka. Zingasetyenziselwa iinkukhu ezimdaka ezikhanyayo. Okwangoku, eyona nto isetyenziswa kakhulu yinkukhu yohlobo olubomvu lweLuodao njengomgca wenkunzi, owela umgca wenkunzi yenkukhu yohlobo lweWhite Leghorn, kwaye inkunzi nemazi zahlulwe ngokusebenzisa iijini zeentsiba ezikhawulezayo nezicothayo ezidityaniswe ngokwesini.

 Iinkukhu ezibeka amaqanda kwiigobolondo zomgubo Iinkukhu ezibeka amaqanda kwiigobolondo zomgubo zahlulwe zibe ziindidi ezilandelayo ngokweendlela zokuvelisa ezixhasayo:

 ①Iinkukhu ezinombala omdaka kunye neenkukhu ezinombala omhlophe zi-hybrids. Ezi ntlobo zisetyenziswa kakhulu kwimveliso ziquka iYakang, iXingza 444, i-Isa powder, iHyland ash, iBaowan Sigaolan powder, iRoman powder, iHessex powder, iNickel powder, iJingbai 939 njalo njalo.

 ②Uhlobo lwe-hybrid phakathi iinkukhu ezibeka amaqandakunye nezinye iintlobo zenkukhu yinkukhu exutyiweyo eveliswa ngokuhlanganisa iinkukhu ezineqokobhe elimhlophe okanye ezineqokobhe elimdaka nezinye iintlobo zenkukhu.
