I-Vitamin K ikwabizwa ngokuba yi-vitamin coagulation.Ngokusuka kwigama layo, sinokwazi ukuba umsebenzi wayo ophambili we-physiological kukukhuthaza ukuhlangana kwegazi.Ngelo xesha, i-vitamin K nayo ibandakanyeka kwi-metabolism yamathambo.

I-Vitamin K1 okwangoku ayisetyenziswanga ngokubanzi kwizongezo zokutya kwezilwanyana ngenxa yeendleko zayo.Uzinzo lwe-menaquinone ekutyeni luye lwancipha emva kwe-extrusion, ukomiswa kunye nokugquma, ngoko ke kusetyenziswe i-derivatives elandelayo ye-VK3 (ngenxa yokubuyisela okuphezulu): i-menadione sodium bisulfite, i-menadione sulfite ye-sodium bisulfate complex, i-menadione sulfonic acid dimethylpyrimidinone, kunye ne-menaquinone nicotinamide sulfite.

Ukunqongophala kwe-Vitamin K kwiikati

Iikati ziintshaba zendalo zeempuku, kwaye kuye kwaxelwa ukuba iikati zaginya ityhefu yeempuku ene-dicoumarin ngempazamo, ekhokelela kwixesha elide lokujika kwegazi.Uninzi lwezinye iimpawu zeklinikhi, ezinje ngesibindi esinamafutha, isifo sokukrala kwamathumbu, i-cholangitis, kunye ne-enteritis, nazo zinokukhokelela kwi-malabsorption ye-lipids, kunye nokusilela kwe-vitamin K yesibini.

Ukuba kuyenzeka ukuba ube nekati ye-Devon Rex njengesilwanyana sasekhaya, kubalulekile ukuqaphela ukuba uhlobo luzalwa lunqongophele kuzo zonke izinto ezinxulumene ne-vitamin K ezinxulumene ne-clotting.

Iimfuno zeVithamin K kwiikati

Ukutya okuninzi kwekati yorhwebo akuncediswa nge-vitamin K kwaye kuxhomekeke kwisenzo sezithako zokutya kwezilwanyana kunye nokuhlanganiswa kumathumbu amancinci.Akukho ngxelo yokuxhaswa kwe-vitamin K ekutyeni kwezilwanyana.Ngaphandle kokuba kukho isixa esikhulu sentlanzi ekutyeni kwesilwanyana esikhulu, akukho mfuneko yokongeza.

Ngokweemvavanyo zangaphandle, iindidi ezimbini zokutya kwekati ezinkonkxiweyo ezityebileyo kwi-salmon kunye ne-tuna zavavanywa kwiikati, ezinokubangela iimpawu zekliniki zokunqongophala kwe-vitamin K kwiikati.Iikati ezininzi zabasetyhini kunye neekati ezityileyo oku kutya zafa kukopha, kwaye iikati ezisindileyo zinexesha elide lokujiya ngenxa yokunqongophala kwevithamin K.

Oku kutya kwekati kunentlanzi kuqulethe i-60μg.kg-1 yevithamin K, ugxininiso olungahlangabezani neemfuno ze-vitamin K zeekati.Iimfuno ze-vitamin K zekati zinokuhlangatyezwa yi-bacterial bacteria synthesis ngokungabikho kokutya kwekati okunentlanzi.Ukutya kwekati okunentlanzi kufuna ukongezwa okongeziweyo ukuhlangabezana nokungaphumeleli kwi-synthesis yamavithamini ngama-microbes amathumbu.

Ukutya kwekati okutyebileyo kwiintlanzi kufuneka kuqulathe i-menaquinone, kodwa akukho datha ikhoyo malunga nokuba ingakanani ivithamin K eyongezwa.I-dose evumelekileyo yokutya yi-1.0mg / kg (4kcal / g), engasetyenziselwa njengento efanelekileyo yokungena.

Hypervitamin K kwiikati

I-Phylloquinone, ifom ye-vitamin K eyenzeka ngokwemvelo, ayizange iboniswe ukuba inetyhefu kwizilwanyana ngayo nayiphi na indlela yokulawula (NRC, 1987).Kwizilwanyana ngaphandle kweekati, amanqanaba etyhefu ye-menadione aphindaphindwa kayi-1000 ubuncinane kwimfuno yokutya.

Ukutya kwekati okusekelwe kwintlanzi, ngaphezu kwesidingo sokunikela ingqalelo kwiimpawu ze-vitamin K, kufuneka kwakhona ingqalelo kwiimpawu ze-thiamine (i-vitamin B1)
