Kangangamashumi eminyaka i-asidi ye-butyric isetyenziswe kwishishini lokutya ukuphucula impilo yamathumbu kunye nokusebenza kwezilwanyana.Izizukulwana ezininzi ezitsha ziye zaziswa ukuphucula ukuphathwa kwemveliso kunye nokusebenza kwayo ukususela kwiimvavanyo zokuqala zenziwa kwi-80s.

1 Uphuhliso lwe-asidi ye-butyric njenge-feed additive

Ngoo-1980 > I-Butyric Acid yayisetyenziselwa ukuphucula uphuhliso lwerumen
1990s> iityuwa ze butyrin acid ezisetyenziselwa ukuphucula ukusebenza kwezilwanyana
2000s> iityuwa ezigqunyiweyo zaphuhliswa: ukufumaneka okungcono kwamathumbu kunye nevumba elincinci
2010s> Iasidi entsha esterified nesebenzayo ngakumbi ibutyric yaziswa

Namhlanje imarike ilawulwa kakuhle yi butyric acid ekhuselweyo.Abavelisi bokutya abasebenza ngezi zongezo abanazo iingxaki kwimiba yevumba kwaye umphumo wezongezo kwimpilo yamathumbu kunye nokusebenza kungcono.Ingxaki ngeemveliso ezigqunyiweyo zesiqhelo koko kuxinana okuphantsi kwe butyric acid.Iityuwa ezigqunyiweyo zihlala zine-25-30% ye-asidi ye-butyric, ephantsi kakhulu.

Uphuhliso lwamva nje lwezongezo ezisekelwe kwi-butyric acid kuphuhliso lweProPhorce™ SR: i-glycerol esters ye-butyric acid.Ezi triglycerides ze butyric acid zinokufumaneka ngokwemvelo kubisi nobusi.Ziyeyona mithombo isebenzayo ye-butyric acid ekhuselweyo kunye ne-concentration ye-butyric acid ukuya kuma-85%.IGlycerol inendawo yokuba neemolekyuli ezintathu ze butyric acid ezincanyathiselwe kuyo ngento ebizwa ngokuba 'yi-ester bond'.Olu nxibelelwano lunamandla lukhona kuzo zonke i-triglycerides kwaye lunokwaphulwa kuphela ngama-enzyme athile (lipase).Kwisityalo kunye nesisu i-tributyrin ihlala yomelele kwaye emathunjini apho i-pancreatic lipase ifumaneka lula i-butyric acid iyakhululwa.

Ubuchwephesha be-esterifying butyric acid bubonakalise ukuba yeyona ndlela isebenzayo yokudala iasidi ye-butyric engenavumba ekhutshwa apho ufuna khona: emathunjini.Umahluko ngeetyuwa ezigqunyiweyo zidweliswe kwifig.2.

Kwi-ESPN ye-20 ePrague, uphononongo oluthelekisayo lwaboniswa kwimpembelelo ye-2 eyahlukeneyo ye-asidi e-butyric esekelwe kwi-broilers.Ulingo lwenziwa kwiziko lophando lwe-ADAS e-UK kwi-2014. Bathelekisa ityuwa ye-sodium edibeneyo (kunye ne-68% yokugqoka) kunye ne-ProPhorce™ SR 130 (55% butyric acid).Amantshontsho angamadoda angama-720 e-Coss308 ahlulwa angamaqela ama-3, aneenbaya ezili-12 zeentaka ezingama-20 kwiqela ngalinye.Ukulinganisa iimeko zorhwebo ngokusondeleyo kunokwenzeka, inkunkuma engcolileyo yongezwa emva kovavanyo lwe-parasitological, ibhaktheriya kunye nentsholongwane.

umsebenzi Tributyrin

1.Ukulungisa i-intestinal villi encinci yezilwanyana kwaye inqanda iibhaktheriya ezinobungozi zamathumbu.

2.Ukuphucula ukufunxa kunye nokusetyenziswa kwezondlo.

3.Unokunciphisa urhudo kunye noxinzelelo lokulunyulwa kwezilwanyana ezincinci.

4.Ukwandisa izinga lokusinda kunye nokuzuza ubunzima bemihla ngemihla yezilwanyana ezincinci.
