Gusimbuza igice cy’amafi n’ifunguro rya soya (SBM) nk’uburyo burambye kandi bw’ubukungu bwakorewe ubushakashatsi ku moko menshi y’ubworozi bw’amafi agamije ubucuruzi, harimo umukororombya w’amazi meza (Oncorhynchus mykiss).Nyamara, soya nibindi bikoresho bishingiye ku bimera birimo urugero rwa saponine nizindi mpamvu zirwanya imirire itera subacute enteritis yo mu mara ya kure muri ayo mafi menshi.Iyi miterere irangwa no kwiyongera kwimbere mu mara, gutwika, hamwe na morphologie idasanzwe itera kugabanuka kwibiryo no gukura nabi.

Mu mukororombya, harimo SBM iri hejuru ya 20% yimirire byagaragaye ko itera soya-enterite, igashyira urwego rwa physiologique kurwego rushobora gusimburwa nimirire isanzwe y’amafi.Ubushakashatsi bwibanze bwasuzumye uburyo butandukanye bwo kurwanya iyi enterite, harimo gukoresha mikorobe yo mu nda, gutunganya ibikoresho kugira ngo ikureho ibintu birwanya imirire, hamwe na antioxydeant na porotiyotike.Bumwe mu buryo butarondoreka ni ugushyiramo trimethylamine oxyde (TMAO) mu biryo by’amafi.TMAO ni cytoprotectant yisi yose, ikusanyirijwe mubwoko bwinshi nka poroteyine na stabilisateur ya membrane.Hano, turagerageza ubushobozi bwa TMAO kugirango twongere enterocyte ituje kandi duhagarike ibimenyetso bya HSP70 byangiza bityo turwanye enterite iterwa na soya kandi biganisha ku kongera umusaruro wibiryo, kugumana no gukura mumazi yumukororombya wamazi meza.Byongeye kandi, turasuzuma niba amafi yo mu nyanja ashonga, isoko ikungahaye kuri TMAO, ashobora gukoreshwa nkuburyo bufatika bwubukungu bwo gukoresha iyi nyongeramusaruro, bigatuma ikoreshwa ryayo mubucuruzi.

Umukororombya uhingwa (Troutlodge Inc.) wabitswe muburemere bwa mbere bwa 40 g na n = 15 kuri buri kigega mubigega bitatu byo kuvura.Ibigega byagaburiwe imwe mu mafunguro atandatu yateguwe ku ntungamubiri zifungura zitanga 40% bya poroteyine igogorwa, ibinure 15%, hamwe no guhura na aside amine nziza.Indyo zirimo amafi 40 yo kugenzura (% yimirire yumye), SBM 40, SBM 40 + TMAO 3 g kg^-1, SBM 40 + TMAO 10 g kg^-1, SBM 40 + TMAO 30 g kg^-1, na SBM 40 + 10% gushonga amafi.Ibigega byagaburwaga kabiri kumunsi kugirango bigaragara ko bihaze ibyumweru 12 hamwe nisesengura rya fecal, hafi, amateka na molekile byakozwe.

Ibyavuye muri ubu bushakashatsi bizaganirwaho kimwe n’akamaro ko gushyiramo TMAO kugira ngo hashobore gukoreshwa cyane ibicuruzwa bya soya yo muri Amerika muri salmonide aquafeeds.
