1. Ngokufika kwexesha lokungabikho kwee-antibiotics, izinto ezinoburhabaxa ezifana neeprobiotics zongezwa kancinci kancinci kwii-pellet feeds. Ngenxa yoko, ngexesha lenkqubo yokuvelisa ukutya, ubushushu buya kuba nefuthe elibalulekileyo kumgangatho wee-pellet feeds. Ukuba ubushushu buphezulu kakhulu ngexesha lokuveliswa kokutya kwee-pellet, buya kubulala izinto ezinoburhabaxa ezifana neeprobiotics. Ukuba ubushushu buphantsi kakhulu, izinto ezibangela iintsholongwane kwi-pellet feed aziyi kususwa ngokupheleleyo, nto leyo ekhokelela ekuvelisweni kokutya kwee-pellet. Umgangatho awukho semgangathweni. Ke ngoko, ukuze kuthintelwe impembelelo yobushushu kuvavanyo, olu vavanyo kukufunda impembelelo yobushushu obuphantsi kunye nomlinganiselo womngxuma wokufa kumgangatho wokucubungula ukutya kwee-pellet phantsi kweemeko zobushushu obuphantsi, ukuze kufundwe ukuveliswa kwee-pellets zokutya kwee-pellet phantsi kweemeko ezifanelekileyo emva kokuba izinto eziluhlaza zivuthiwe. Nokuba igcwele na kwaye iyahlangabezana nemigangatho yovavanyo lomgangatho wee-particle. Injongo ephambili yolu vavanyo kukubonelela ngesikhokelo esithile sethiyori sokuvelisa ukutya kwee-pellet zezilwanyana.
2.1 Izithako eziphambili zokutya okulingwayo kunye nezinto eziluhlaza zepellet ziquka: umbona, umgubo wentlanzi, ityuwa, i-methionine, i-threonine, njl. Umbona kufuneka utyunyuzwe ube ngamasuntswana amancinci angama-11.0mm, uze emva koko izinto eziluhlaza zilinganiswe ngokweemfuno zesondlo, uze uvuthwe. Emva kokuphola, kongezwa izinto ezinobushushu ezifana neeprobiotics, kwaye ekugqibeleni zinyibilikiswe zibe ngamasuntswana. Amaqondo obushushu eepellets zokutya ezilungisiweyo ngokubanzi angama-60, 50, 40, kunye nama-30°C, kwaye ubude kunye nobubanzi bemingxuma ye-die ngokubanzi yi-7:1, 6:2, kunye ne-10:1, kunye ne-300 mg/kg yezinto zeprobiotic zongezwa ngokusekelwe kwizixhobo zovavanyo. , kwaye amaqondo obushushu e-pellet nawo kufuneka anyibilikiswe ukukhusela umsebenzi weeprobiotics. Ukongeza, ezinye iivithamini kufuneka zongezwe kwikhilogram nganye yokutya kwepellet ukuqinisekisa ukuba izinto zesondlo zokutya kwepellet zinokuhlangabezana neemfuno zokutya kwesizwe.
2.2 Ukuthatha iisampulu kunye nokuqokelela iisampulu
Ukuze kuqinisekiswe ukuba ukutya kwepellet okuvelisiweyo kuyafaneleka, emva kokuba ukutya kwepellet kuvelisiwe, kuyimfuneko ukukhetha ngokungacwangciswanga ukutya kwepellet ukuze kuhlolwe umgangatho.
2.3 Imigangatho kunye neendlela zokuhlola umgangatho
2.3.1 Inqanaba le-gelatinization yesitatshi
Xa kuvavanywa inqanaba le-gelatinization yesitatshi kwiisampuli zokutya kwe-pellet, abasebenzi banokusebenzisa i-amylase ukuyifumanisa. Yongeza i-amylase kwisitatshi, kwaye ubale impendulo yekhemikhali phakathi kwe-amylase kunye nesitatshi. Okokugqibela, yongeza isisombululo se-iodine, kwaye ugwebe inqanaba le-gelatinization yesitatshi ngokujonga ubunzulu bombala wesiphumo sempendulo yekhemikhali.
2.3.2 Ukuqina kwee-pellets zokutya
Ukuze kuvavanywe umgangatho wesondlo se-pellet, ubulukhuni bayo bufanele buvavanywe. Umgangatho wobulukhuni besondlo se-pellet kufuneka ubhekisele kulwazi olufanelekileyo.
2.3.3 Isalathisi sokunyamezelana kokutya kwepellet
Faka ukutya kwepellet kwibhokisi ejikelezayo uze ukujikelezise nge-50r/min imizuzu engama-20. Emva kokumisa, khupha ukutya kwepellet uze ulinganise ubunzima obuseleyo bokutya kwepellet uze ukugalele nge-m.
3. iziphumo zovavanyo
3.1 Impembelelo yomgangatho wesondlo, ubushushu kunye nomlinganiselo wobubanzi bemingxuma kumgangatho kunye nobunzima besondlo se-pellet. Olu vavanyo lufunda ikakhulu indlela yokutshintsha komgangatho wesondlo se-pellet phantsi kweemeko zobushushu obuphantsi. Izinto eziphambili ezisetyenziswayo ziquka umbona, umgubo wesoya, njl.njl., ezicutshungulwa kwaye zivuthwe. Emva koko, emva koko ziyaqhekeka kumaqondo obushushu aphantsi. Kufunyaniswe ukuba umgangatho wesondlo se-pellet awuchaphazeleki kuphela bubungakanani bezinto ezisetyenziswayo, kodwa bukwachaphazeleka bububanzi bomngxuma womatshini wokucubungula. Xa ubushushu bokuvelisa ukutya kwe-pellet buphezulu, umlinganiselo wobubanzi kunye nobude bomngxuma we-membrane womatshini mkhulu, kwaye ubunzima bokutya kwe-pellet obuvelisiweyo buphezulu, kodwa kuya kuchaphazela umsebenzi wee-probiotics kwisondlo, kwaye amandla asetyenziswa ekuveliseni ukutya kwe-pellet aya kwanda ngokufanelekileyo. Iziphumo zovavanyo zibonisa ukuba ukuqinisekisa ukuba umgangatho wesondlo se-pellet esivelisiweyo ufikelela kumgangatho, kufuneka uveliswe phantsi kweemeko ezinjalo zemveliso.
3.2 Impembelelo yobushushu bokulungisa kunye nobubanzi bemingxuma yokufa kwizinga le-gelatinization yesitatshi kwi-pellet feed. Emva kothotho lwezifundo zovavanyo, kufunyenwe ukuba ubushushu bokulungisa oomatshini kunye nobubanzi bemingxuma yokufa zinempembelelo ebaluleke kakhulu kwizinga le-gelatinization yesitatshi kwi-pellet feed. Phantsi kweemeko ezifanayo zobushushu, okukhona ububanzi bemingxuma yokufa buncinci, kokukhona impembelelo enkulu kwizinga le-gelatinization yesitatshi kwi-pellet feed.
3.3 Impembelelo yobushushu obuphantsi kunye nomlinganiselo womngxuma odityanisiweyo ukuya kubude kwizinga lokugcina iiprobiotics kwiigranules. Emva kothotho lweemvavanyo, kwafunyaniswa ukuba umsebenzi weeprobiotics uchaphazeleka kakhulu bubushushu. Ukuba ubushushu buphezulu kakhulu ngexesha lokuveliswa kokutya kwepellet, kuya kunciphisa ngokuthe ngqo umsebenzi weeprobiotics. Ke ngoko, ukuqinisekisa ukugcinwa kweeprobiotics ngexesha lenkqubo yokuveliswa kokutya kwepellet kunye nemigangatho yovavanyo lomgangatho wokutya kwepellet, kuyimfuneko ukuvelisa ukutya kwepellet phantsi kweemeko zobushushu obuphantsi.
4. Isiphelo
Ngolu vavanyo, kunokufunyaniswa ukuba umgangatho, ubulukhuni kunye nenani leeprobiotics kwi-pellet feed azichatshazelwa kuphela bubushushu bemveliso, kodwa nakububanzi bomngxuma wokufa. Ngoluhlu lwezifundo, kufunyenwe ukuba ukusebenzisa izinto ezivuthiweyo zokwenza ukutya kwe-pellet phantsi kweemeko zobushushu obuphantsi kunceda ekuphuculeni umgangatho kunye nobulukhuni bokutya kwe-pellet; phantsi kweemeko zobushushu ezifanayo, kokukhona umlinganiselo wobubanzi bomngxuma wokufa uphezulu, kokukhona ukuveliswa kwe-pellets kungcono. Amandla asetyenziswa kwinkqubo yokondla aphezulu. Ngovavanyo, kufunyenwe ukuba isisombululo esifanelekileyo sokwenza ukutya kwe-pellet kukusebenzisa izixhobo ezinomlinganiselo wobubanzi bomngxuma wokufa we-6:1 kubushushu be-65°C ukuvelisa ukutya kwe-pellet komgangatho ophezulu.
