Ukutshintshwa ngokuyinxenye komgubo wentlanzi kunye nomgubo weembotyi zesoya (SBM) njengenye indlela ezinzileyo neyoqoqosho iye yaphononongwa kwiintlobo ezininzi ezijoliswe ekurhwebeni ngezilwanyana zasemanzini, kuquka i-rainbow trout (i-rainbow trout)Oncorhynchus mykiss).Nangona kunjalo, i-soy kunye nezinye izinto ezisekelwe kwizityalo ziqulethe amanqanaba aphezulu e-saponins kunye nezinye izinto ezichasene nesondlo ezenza i-subacute enteritis ye-distal intestine kwiintlanzi ezininzi zezi ntlanzi.Le meko ibonakala ngokunyuka kwamathumbu emathunjini, ukudumba, kunye nokungahambi kakuhle kwe-morphological ekhokelela ekwehleni kokusebenza kokutya kunye nokukhubazeka kokukhula.

Kwi-rainbow trout, kubandakanywa ne-SBM ngaphezu kwe-20% yokutya kuye kwaboniswa ukuba kubangele i-soy-enteritis, ibeka i-physiological threshold kwinqanaba elinokuthi litshintshwe kwi-standard aquaculture diet.Uphando lwangaphambili luye lwavavanya inani leendlela zokulwa nale enteritis, kubandakanywa ukuguqulwa kwe-gut microbiome, ukulungiswa kwezithako zokususa izinto ezichasene nesondlo, kunye ne-antioxidant kunye ne-probiotic additives.Enye indlela engakhange ihlolwe kukuqukwa kwe-trimethylamine oxide (TMAO) kwisondlo sasemanzini.I-TMAO yi-cytoprotectant yendalo yonke, eqokelelwe kwiintlobo ezininzi njengeprotheni kunye ne-membrane stabilizer.Apha, sivavanya isakhono se-TMAO sokwandisa uzinzo lwe-enterocyte kunye nokucinezela isibonakaliso se-HSP70 esivuthayo ngaloo ndlela silwa ne-enteritis eyenziwe ngesoya kwaye ikhokelele ekonyukeni kokutya okusebenzayo, ukugcinwa kunye nokukhula kwi-trout yamanzi amnandi.Ngapha koko, sivavanya ukuba i-marine fish solubles, umthombo otyebileyo we-TMAO, unokusetyenziswa njengendlela yoqoqosho yokulawula olu songezo, okwenza ukuba isicelo saso sisetyenziswe kwisikali sorhwebo.

I-rainbow trout efamayo (i-Troutlodge Inc.) zaye zagcinwa kubunzima bokuqala obuyi-40 g kunye ne-n=15 ngetanki nganye kwiitanki zokunyanga eziphindwe kathathu.Amatanki atyiswa enye yezidlo ezintandathu ezilungiselelwe ngokwesiseko sezakhamzimba ezigaywayo ezibonelela ngama-40% eprotheyini egaywayo, i-15% yamafutha akrwada, kunye nokuhlangabezana nemilinganiselo efanelekileyo ye-amino acid.Ukutya kwakuquka i-fishmeal 40 control (% of dry diet), SBM 40, SBM 40 + TMAO 3 g kg^-1, SBM 40 + TMAO 10 g kg^-1, SBM 40 + TMAO 30 g kg^-1, kunye ne-SBM 40 + 10% ye-solubles yentlanzi.Iitanki zondliwa kabini yonke imihla ukuya kwi-satiation ecacileyo kwiiveki ze-12 kunye ne-fecal, proximate, histological and molecular analysis eyenziwa.

Iziphumo zolu phononongo ziya kuxutyushwa kunye nokusebenziseka kokubandakanya i-TMAO ukwenza ukusetyenziswa okuphezulu kweemveliso zesoya zase-US kwi-salmonid aquafeeds.
