Ua ʻimi ʻia ka hoʻololi hapa o ka ʻai iʻa me ka ʻai soybean (SBM) ma ke ʻano he ʻokoʻa hoʻomau a hoʻokele waiwai i kekahi mau ʻano iʻa iʻa i hoʻopaʻa ʻia ma ka pāʻoihana, e like me ke anuenue wai maʻemaʻe.ʻO Oncorhynchus mykiss).Eia nō naʻe, ʻo ka soy a me nā mea kanu ʻē aʻe i loaʻa i nā kiʻekiʻe o nā saponins a me nā mea anti-nutritional ʻē aʻe e hoʻoulu ai i ka subacute enteritis o ka ʻōpū ʻōpū i loko o ka nui o kēia mau iʻa.Hōʻike ʻia kēia ʻano e ka piʻi ʻana o ka intestinal permeability, ka ʻāʻī, a me nā mea ʻino morphological e alakaʻi ana i ka emi ʻana o ka pono o ka hānai a me ka ulu ʻana.

I loko o ke ānuenue trout, me ka SBM ma luna o 20% o ka meaʻai i hōʻike ʻia e hoʻoulu i ka soy-enteritis, e kau ana i ka paepae physiological ma ka pae i hiki ke hoʻololi ʻia i kahi meaʻai iʻa maʻamau.Ua nānā ka noiʻi mua i nā ʻano hana e hakakā ai i kēia enteritis, me ka hoʻoponopono ʻana i ka microbiome o ka ʻōpū, ka hoʻoili ʻana i ka meaʻai e hoʻoneʻe i nā mea anti-nutritional, a me nā mea hoʻohui antioxidant a me probiotic.ʻO kekahi ala ʻike ʻole ʻia ʻo ia ka hoʻokomo ʻana i ka trimethylamine oxide (TMAO) i loko o nā meaʻai iʻa.ʻO TMAO kahi cytoprotectant āpau, i hōʻiliʻili ʻia i nā ʻano he nui e like me ka protein a me ka stabilizer membrane.Maʻaneʻi, ho'āʻo mākou i ka hiki o TMAO e hoʻonui i ka enterocyte paʻa a hoʻopaʻa i ka hōʻailona HSP70 a me ka hakakāʻana i ka enteritis soy-induced a alakaʻi i ka hoʻonuiʻana i ka pono o ka hānai, ka mālamaʻana a me ka uluʻana i ka wai anuanu.Eia hou, ke nānā nei mākou inā hiki ke hoʻohana ʻia nā mea hoʻoheheʻe iʻa moana, kahi kumu waiwai o TMAO, ma ke ʻano he mea hoʻokele waiwai no ka lawelawe ʻana i kēia mea hoʻohui, e hiki ai ke hoʻohana ʻia ma ka pālākiō kalepa.

Ua mālama ʻia ka ʻiʻo ānuenue i mahi ʻia (Troutlodge Inc.) ma ke ʻano kaumaha mua o 40 g a me n=15 i kēlā me kēia pahu i loko o nā pahu lapaʻau ʻekolu.Ua hānai ʻia nā pahu i hoʻokahi o nā meaʻai ʻeono i hoʻomākaukau ʻia ma ke kumu meaʻai digestible e hāʻawi ana i ka 40% digestible protein, 15% crude fat, a me ka hoʻokō ʻana i nā koina amino acid kūpono.ʻO nā meaʻai i loaʻa i ka ʻai iʻa 40 mana (% o ka meaʻai maloʻo), SBM 40, SBM 40 + TMAO 3 g kg^-1, SBM 40 + TMAO 10 g kg^-1, SBM 40 + TMAO 30 g kg^-1, a me SBM 40 + 10% mea hoʻoheheʻe iʻa.Hānai ʻia nā pahu i ʻelua manawa i kēlā me kēia lā e ʻike i ka māʻona no nā pule he 12 a mālama ʻia nā fecal, proximate, histological and molecular analysis.

E kūkākūkā ʻia nā hopena o kēia haʻawina a me ka pono o ka hoʻokomo ʻana i ka TMAO e hiki ai i ka hoʻohana kiʻekiʻe o nā huahana soy US i loko o nā wai salmonid.
