Ukuthelekisa ukutya kwezinja akukho lula. Ukuleyibhile kunokuba nzima ukucacisa, kwaye abaninzi abanini bezinja bashiywe bezibuza ukuba loluphi uphawu olunesondlo ngokwenene. Xa uphinda uphose ekukhetheni ukutya okomileyo okanye okunkonkxiweyo, amanzi aba nodaka ngakumbi. Okokuqala, kufuneka uqonde ukuba uhlalutyo oluqinisekisiweyo luthetha ntoni, kwaye emva koko ufunde ukuguqula ezo pesenti zezondlo zibe ngamanani onokuwathelekisa kuzo zonke iintlobo zokutya kwesilwanyana sasekhaya kunye neentlobo.
I-AAFCO kunye neSondlo sokutya kwezilwanyana
I-Association of American Feed Control Officers (AAFCO) ngumbutho olawulayo obeka imigangatho yesiqulatho sesondlo sokutya kwezinja kunye nokunye ukutya kwezilwanyana. Ngokomthetho, konke ukutya kwesilwanyana sasekhaya kufuneka kufezekise ezona mfuno zisezantsi ze-AAFCO zibhalwe I-100% igcwele isondlo . Nangona kunjalo, ngenxa yokuba ukutya kwesilwanyana kuhlangabezana neemfuno ezincinci ze-AAFCO akuqinisekisi ukuba konke ukutya kwezinja kunomgangatho olinganayo.
Amanqaku anxulumeneyoQwalasela uMgangatho weZithako kunye neDigestibility
Ukutya kwenja eyomileyo emibini eneneni inokuba ne-18% yeprotheyini encinci; nangona kunjalo, umthombo waloo proteni umisela indlela etyisa ngayo. Inyama yokwenyani kunye neemveliso zenyama ezingabizi kakhulu zombini zineproteni. Nangona kunjalo, inyama yokwenyani ilula ukugaywa, kwaye ke inja yakho iyakwazi ukufunxa ngakumbi izondlo njengoko ukutya kudlula kwinkqubo yakhe.
Ukufunxa kakhulu izondlo zilingana nesitulo esisezantsi kuba ukutya okuninzi kugaywe ngokupheleleyo. Umbuzo wokwetyisa ukwabhekiselele kwezinye izithako ekutyeni kwesilwanyana sasekhaya. Ukuba inja yakho ayikwazi ukutsala lonke ixabiso lezondlo kuzo, ziziphi izinto ezilungileyo?
Ngoko kutheni zonke izinja zingasebenzisi ezona zithako zigaywayo, ezikumgangatho ophezulu? Ukusebenzisa izithako ezikumgangatho ophantsi, ezingabizi kakhulu ezisavumela ukutya ukuba kuhlangabezene nemigangatho ye-AAFCO kwandisa umda wenzuzo yomenzi.
I-Dry Kibble vs. Ukutya kweNja enkonkxiweyo
Umgaqo wobhontsi wokutya kwezinja ngulo: Okukhona kusezantsi ukuxinana kwezondlo, kokukhona kukhula ubungakanani obufunekayo bokutya ukuze kufunyanwe isixa esicetyiswayo sesondlo.
Ukutya kwenja enkonkxiweyo ngokuqhelekileyo kunomxholo ophezulu wamanzi kune-kibble eyomileyo, oku kuthetha ukuba kuya kufuneka unike inja yakho ukutya okukhulu kwenja enkonkxiweyo ukuze ufumane umlinganiselo ofanayo wezondlo njengoko ziqulethwe kwinkonzo encinci ye-kibble eyomileyo. Ayisiyonto imbi leyo, ukuba nje uyawuqonda umahluko. Zombini iintlobo zokutya zinokunceda isilo-qabane sakho, kwaye ayilombono ilungileyo ukondla uhlobo olunye lokutya kuphela.
Oko kwathiwa, umxholo wamanzi wodwa awunakukuxelela ukuba uhlobo oluthile lokutya luphezulu kumxholo wesondlo wokwenyani kunomnye. Ngaloo nto, kufuneka ujonge uhlalutyo oluqinisekisiweyo kwaye ufunde ukucacisa intsingiselo yokwenyani.
Ukuqonda Uhlalutyo Oluqinisekisiweyo
I-AAFCO eneneni isekela iimfuno zabo ze-100% zokutya kwenja okunesondlo ngokungqongqo kumxholo 'owomileyo'. Nangona kunjalo, iitheyibhile zohlalutyo malunga nazo zonke iilebhile zokutya kwezinja zitshintshiwe ukubonisa iingcebiso zepakethe nganye yokutya. Olu hlalutyo lunokuba ludideke kancinane, ekubeni isixa sokutya osifunayo ukuze ufumane iziphumo eziqinisekisiweyo zihluka ukusuka kwi-brand ukuya kwi-brand. Ukuba ufuna ukwenza uthelekiso olunolwazi lwenyani, kufuneka ujonge ezi pesenti ngendlela efanayo ne-AAFCO isenza ngayo, ngomxholo owomileyo.
Ifomula yokuguqulwa yokuthelekisa imixholo yezondlo
Ngokutsho kwe Iziko lezonyango lwezilwanyana kwiYunivesithi yaseOhio State , 'Ukuthelekisa ukutya kumbandela owomileyo kuthatha iiyantlukwano kumxholo wamanzi ngaphandle kwe-equation ukuze izondlo zithelekiswe ngokufanayo.' Nantsi indlela yokukunceda uguqule itheyibhile yohlalutyo eqinisekisiweyo ibe yiprofayile yomcimbi owomileyo ukuze uthelekiseke lula.
- Qala nge-100%, kwaye uthabathe ipesenti yokufuma okudweliswe kwileyibhile. Oku kukunika ipesenti yokwenene yezinto ezomileyo kwimveliso yokutya.
- Thatha ipesenti edwelisiweyo yesinye sezondlo eziphambili, kwaye wahlule elo nani ngepesenti yezinto ezomileyo. Oku kuya kukunika eyona pesenti yokomileyo yeso sondlo sithile ekutyeni. Phinda inkqubo yesondlo ngasinye kwitheyibhile yohlalutyo oluqinisekisiweyo kwiphakheji.
Ukuthelekisa umxholo woMba owomileyo wokutya okumanzi kunye nokomileyo
Umzekelo, yithi isiqulatho samanzi sohlobo oluthile lokutya kwenja enkonkxiweyo zidweliswe njenge-75%, kwaye uhlalutyo lomxholo weprotheyini ekrwada luqinisekisiwe ukuba luncinci luyi-6%.
- Thabatha amanzi angama-75% (.75) kwisiqulatho samanzi kwi-100% (1.0) iyonke imveliso, kwaye oko kushiya i-25% (0.25) yezinto ezomileyo.
- Yahlula loo 6% (0.06) yeprotheyini ngama-25% (0.25) eyomileyo, kwaye ufumana isiqulatho seprotheyini eyomileyo esiyi-24% (0.24).
Ngoku ingxowa yokutya kwenja eyomileyo ithwala ukufuma okuncinci kakhulu. Ukusebenzisa ifomula efanayo, imveliso equlethe i-6% (0.06) ukufuma iqulethe umxholo owomileyo we-94% (0.94). Ukuba ubuncinci bohlalutyo lweprotheyini ekrwada yi-18%, ukwahlula elo nani (0.18) ngesixa sento eyomileyo (0.94) ijikelezisa ukuya kumxholo weprotein oyomileyo phakathi kwe-19% kunye ne-20% (okanye 0.1914893617021277 ukuba ngqo).
Kulo mzekelo, ukutya okomileyo kuqulethe umxholo weprotheyini ephantsi kunokonkcenkceshe, kodwa iziphumo ziya kuhluka njengoko iipesenti zitshintsha ukusuka kwi-brand ukuya kwi-brand, eyona ngongoma yokuguqula iipesenti zomtho owomileyo ukuthelekisa.
Lusebenzise olu Luthelekiso
Ngoku uyayazi ifomula, unokuguqula ezinye iipesenti zezondlo ezikrwada ezidweliswe kuyo nayiphi na itheyibhile yohlalutyo eqinisekisiweyo ibe linani elinokuthelekiswa ngokwenyani ukusuka kwenye ukutya kwenja ukuya kwelinye. Oku kuya kukunceda wenze olona khetho lulungileyo lokutya kwesilwanyana sakho sasekhaya ngokusekwe kwiimfuno zaso zobuqu, apho ugqirha wakho wezilwanyana anokukunceda ukuba usivavanye.
