Ithonya Lezinto Ezingokwemvelo Ekukhuleni Kwezilwane
Ukukhula kwezilwane kuyinqubo eyinkimbinkimbi yezinto eziphilayo, ebonakala ngokwanda kobukhulu bomzimba nesisindo, kanye nokuthuthukiswa kwezitho zomzimba kanye nemisebenzi yomzimba. Ukukhula akwenzeki ngengozi kodwa kuthonywa ukusebenzisana kwezici zofuzo kanye nezemvelo. Izakhi zofuzo zinquma amandla okuqala, kodwa indawo ezungezile inquma kakhulu ukuthi lawo mandla afinyelelwa kahle yini. Ngakho-ke, ukuqonda ithonya lezici zemvelo ekukhuleni kwezilwane kubalulekile ekukhuliseni izilwane, ukulondolozwa kwezilwane zasendle, ukufuywa kwezinhlanzi, ngisho nempilo yezilwane ezifuywayo.
1. Ukutholakala kanye nekhwalithi yokuphakelwa
Ukudla kuyisici semvelo esithinta kakhulu ukukhula. Izilwane zidinga amandla nezakhamzimba ukwakha izicubu ezintsha, ukulungisa amaseli alimele, nokugcina i-metabolism yansuku zonke. Uma ukudla kwanele futhi kusezingeni elihle, ukukhula kuvame ukuba ngokushesha futhi kuzinzile. Ngakolunye uhlangothi, ukudla okunganele noma ukudla okungekuhle kungaholela ekukhuleni okulimele, ukwehla kwesisindo, kanye nokwanda kokuthambekela ezifweni.
Ikhwalithi yokudla ihlanganisa amaprotheni, amafutha, ama-carbohydrate, amavithamini, okuqukethwe kwamaminerali, kanye nebhalansi yama-amino acid. Isibonelo, amaprotheni abalulekile ekwakhekeni kwemisipha nama-enzyme. Ezilwaneni ezisencane ezikhula, ukuntuleka kwamaprotheni kuvame ukuba mkhulu kakhulu kunasezikhulile. Amaminerali afana ne-calcium ne-phosphorus adlala indima enkulu ekwakhekeni kwamathambo, kuyilapho amavithamini A, D, no-E esekela ukukhula kanye nokuzivikela komzimba.
Ngokwemvelo, ukutholakala kokudla kuthonywa yizinkathi zonyaka. Izilwane eziningi zikhula ngokushesha ngezikhathi zokudla okuningi, bese zincipha lapho ukudla kuntula. Ezinhlelweni zokufuya izilwane zasemanzini, ukuphathwa kokudla (inani, imvamisa, kanye nohlobo lokudla) kuyisihluthulelo sokukhula okuhle kanye nokusebenza kahle kokudla okuphezulu.
2. Izinga Lokushisa Lemvelo kanye Nesimo Sezulu
Izinga lokushisa lithinta izinga lokuguqulwa kwezakhi zomzimba kanye nezidingo zamandla. Ezilwaneni ezinegazi elifudumele (izilwane ezincelisayo nezinyoni), amazinga okushisa aphezulu kakhulu—ashisa kakhulu noma abandayo kakhulu—aphoqa umzimba ukuthi usebenzise amandla amaningi ukuze ulondoloze izinga lokushisa langaphakathi. Ngenxa yalokho, amandla okufanele asetshenziswe ekukhuleni adluliselwa ekulawuleni izinga lokushisa.
Ezilwaneni ezinegazi elibandayo (izinhlanzi, izilwane eziphila emanzini nasemanzini, izilwane ezihuquzelayo), izinga lokushisa lemvelo libaluleke kakhulu ngoba izinga lokushisa lomzimba libonisa izinga lokushisa elizungezile. Ukukhula kwezinhlanzi, isibonelo, kuncike kakhulu ekushiseni kwamanzi. Uma izinga lokushisa liphansi kakhulu, i-metabolism iyahamba kancane, okuholela ekunciphiseni isifiso sokudla kanye nokukhula okubambezelekile. Uma liphezulu kakhulu, ukucindezeleka kuyanda futhi kungaholela ezinkingeni zomzimba ngisho nasekufeni.
Isimo sezulu sihlanganisa nomswakama kanye nemvula. Umswakama ophezulu ungandisa ingozi yezifo zesikhumba noma izifo zesikhunta kwezinye izilwane, kuyilapho umswakama ophansi kakhulu ungaholela ekuphelelweni amanzi emzimbeni. Ukuhlanganiswa kwezinga lokushisa kanye nomswakama kuvame ukufingqwa njengenkomba yenduduzo, ikakhulukazi emfuyweni njengezinkomo nezinkukhu. Lapho inkomba yenduduzo imbi, ukukhula kungancipha ngisho nalapho ukudla kwanele.
3. Ukutholakala Kwamanzi kanye Nekhwalithi
Amanzi ayisici esibalulekile somzimba wesilwane futhi adlala indima ekugayweni kokudla, ukujikeleza kwegazi, ukulawulwa kwezinga lokushisa, kanye nokulahlwa kwemfucuza. Ukuntuleka kwamanzi kubangela ukuphelelwa amanzi emzimbeni, ukuncipha kokudla, kanye nokuphazamiseka kwe-metabolic, okungaholela ekukhuleni okulimele.
Ikhwalithi yamanzi nayo ibalulekile. Amanzi angcoliswe amabhaktheriya, amagciwane, noma amakhemikhali angabangela izifo zokugaya ukudla, ubuthi, kanye nokuncipha kokuzivikela komzimba. Ekufuyweni kwezinhlanzi, imingcele efana ne-pH, umoya-mpilo oncibilikisiwe, i-ammonia, i-nitrite, kanye nosawoti kuthinta kakhulu ukukhula kwezinhlanzi nezimfanzi. Amanzi anamazinga aphansi omoya-mpilo angacindezela isifiso sokudla futhi anciphise ukuguqulwa kokudla kube yinyama.
4. Ubuningi babantu kanye nendawo yokuhlala
Ubuningi babantu buhlotshaniswa nokuncintisana ngokudla, amanzi, isikhala, kanye nokufinyelela indawo yokukhosela. Ukuminyana kwenza izilwane zibe sengozini enkulu yokucindezeleka, kwandisa ulaka, futhi kusheshise ukusabalala kwezifo. Ukucindezeleka okungapheli kubangela amazinga aphezulu ama-hormone okucindezeleka njenge-cortisol, angacindezela ukukhula, aphazamise amasosha omzimba, futhi anciphise ukusebenza kahle kokusetshenziswa kwezakhamzimba.
Ekulimeni okujulile, kufanele kucatshangelwe ubuningi bezindlu ezifanele. Izinkukhu ze-broiler, isibonelo, zidinga isikhala esanele sokuhambahamba nokufinyelela ukudla namanzi ngaphandle kokuncintisana ngokweqile. Uma zigcwele kakhulu, ukukhula ngeke kungalingani: ezinye izilwane ziyachuma, kanti ezinye zisala ngemuva ngenxa yokuncintisana.
5. Izifo, Izimuncagazi, kanye Nokuhlanzeka Kwemvelo
Izifo kanye nezilokazane ziyizinto eziphilayo zemvelo ezithinta kakhulu ukukhula. Ukutheleleka ngamagciwane, amagciwane kanye nezikhunta kunganciphisa isifiso sokudla, kwandise izidingo zamandla okulwa nezifo, futhi kulimaze izicubu zomzimba. Izilokazane ezifana nezimpethu zamathumbu zimunca izakhamzimba ezivela kubasingathi bazo, okubangela ukungondleki kahle ngisho nalapho izilwane zidla ukudla okwanele.
Ukuhlanzeka kwekheji noma indawo yokuhlala kuthinta izinga lokuchayeka ezifweni ezibangelwa amagciwane. Indawo engcolile, enomswakama, nengcolile isheshisa ukukhula kwamagciwane abangela izifo. Ngaphezu kwalokho, ukuphefumula okungenampilo kwandisa amazinga e-ammonia, okungalimaza indlela yokuphefumula futhi kunciphise ukusebenza kahle kokukhula, ikakhulukazi ezinkukhu.
Izinhlelo zokuhlanzeka, ukugoma, kanye nokulawula izimuncagazi kubalulekile ekugcineni ukukhula okuhle. Ngokunciphisa umthwalo wesifo, amandla amaningi kanye nezakhamzimba kungabekwa ekwakhekeni kwezicubu.
6. Ukukhanya kanye ne-Photoperiodism
Ukukhanya kuthonya imijikelezo yezinto eziphilayo zezilwane ngokulawulwa kwamahomoni. Ezinyonini, isikhathi sokuvezwa kokukhanya (isikhathi se-photo) singathinta isifiso sokudla, umsebenzi, kanye nokukhiqizwa kwamahomoni athile ahlobene nokukhula nokuzala. Ukuphathwa kokukhanya kuvame ukusetshenziswa emapulazini ezinkukhu, kokubili ukulawula izikhathi zokudla kanye nokugcina izimo zomzimba ezisekela ukukhuluphala.
Ezilwaneni zasendle, ubude bemini nobusuku buyashintsha ngezinkathi zonyaka futhi buthinta amaphethini okudla kanye nemisebenzi yokudla. Ngaphansi kwezimo ezithile, ukukhanya okungafanele kungabangela ukucindezeleka noma kuphazamise ibhalansi yama-hormone, okuthinta ukukhula.
7. Ukucindezeleka Kwemvelo Nokuphazamiseka Kokuziphatha
Ukucindezeleka akuhlobene nje nokuminyana, kodwa futhi nomsindo, ukuhamba, izinguquko ezisheshayo zemvelo, izilwane ezidla ezinye izilwane, noma ukuphathwa kabi ngabantu. Ukucindezeleka kwesikhathi esifushane kunganciphisa isifiso sokudla okwesikhashana, kodwa ukucindezeleka okungapheli kungacindezela amasosha omzimba futhi kuvimbele ukukhula kakhulu.
Isibonelo, izilwane ezibhekana nokuphazamiseka okuvamile zizosebenzisa amandla amaningi ekuqapheni nasekunyakazeni, ukuze amakhalori asetshenziswayo angaguqulwa abe izicubu zomzimba ngempumelelo. Ukucindezeleka kungaphazamisa futhi amaphethini okulala, abalulekile ekuvuseleleni umzimba kanye nokukhululwa kwama-hormone okukhula ezinhlotsheni eziningi.
8. Ukusebenzisana Kwezinto Zemvelo: Ukungami Wedwa
Izici zemvelo azivamile ukusebenza zodwa. Amazinga okushisa aphezulu avame ukuhambisana nezidingo zamanzi eziphakeme. Ubuningi obukhulu bandisa ingozi yezifo. Ukudla okungekuhle kwandisa umthelela wezinambuzane. Ngakho-ke, ukukhula kwezilwane kumele kuqondwe njengomphumela ohlangene wezimo ezahlukahlukene. Isilwane singase sibe nokudla okwanele, kodwa ekushiseni okukhulu kanye nomoya ongemuhle, ukukhula kusenokuncipha ngenxa yokucindezeleka kokushisa kanye nezinkinga zokuphefumula.
Emikhubeni yemfuyo kanye nokulima, indlela ephumelelayo ukuphathwa okuhlanganisiwe: ukuqinisekisa ukudla okulinganiselayo, amanzi ahlanzekile, izimo zokuhlala ezikhululekile, ubuningi obuhle, kanye nokuphepha okuhle kwezinto eziphilayo. Ngokwemvelo, ukuqonda lokhu kuxhumana kusiza nemizamo yokonga, isibonelo ngokugcina ikhwalithi yendawo yokuhlala, imithombo yamanzi kanye nokutholakala kokudla kwemvelo.
Isiphetho
Ukukhula kwezilwane kuthonywa kakhulu yizici zemvelo, okuhlanganisa ukudla, izinga lokushisa, amanzi, ubuningi, impilo yemvelo, ukukhanya, kanye namazinga okucindezeleka. Indawo esekelayo yenza izilwane zikwazi ukusebenzisa kahle izakhamzimba ukuze zikhule, kuyilapho indawo empofu iphoqa umzimba ukuthi udlulisele amandla ukuze uphile. Ngakho-ke, imizamo yokuthuthukisa ukukhula kwezilwane—kungakhathaliseki ukuthi kusekufuyweni kwezilwane, ekulimeni, noma ekulondolozweni—kumele igxile ekuthuthukiseni izimo zemvelo zizonke. Ngendawo efanele, izilwane zingafinyelela amandla azo ezakhi zofuzo, zithuthukise impilo yazo, futhi zithuthukise umkhiqizo.
