Zokopa nsombandi mawu ofala a zinthu zokopa nsomba ndi zinthu zolimbikitsa chakudya cha nsomba. Ngati zowonjezera za nsomba zagawidwa m'magulu asayansi, ndiye kuti zinthu zokopa ndi zinthu zolimbikitsa chakudya ndi magulu awiri a zowonjezera za nsomba.

Zomwe nthawi zambiri timazitcha kuti zokopa nsomba ndi zinthu zopatsa thanzi nsomba. Zinthu zopatsa thanzi nsomba zimagawidwa m'magulu awiri: zinthu zopatsa thanzi nsomba zomwe zimagwira ntchito mwachangu komanso zinthu zopatsa thanzi nsomba zomwe zimakhala nthawi yayitali. Zingagawanso m'magulu awiri: zinthu zopatsa thanzi kukoma, zinthu zopatsa thanzi, ndi zinthu zopatsa thanzi. Tidzayerekeza ndikuwunika momwe zinthu zopatsa thanzi nsomba zambiri za m'madzi oyera zimakhudzira kudyetsa kwawo.

1, Betaine.

Betainendi alkaloid yomwe imachokera ku shuga beet molasses, yomwe ingagwiritsidwe ntchito ngati chowonjezera mu chakudya cha nsomba kuti ilowe m'malo mwa methionine ndi choline mu methyl, kupititsa patsogolo ntchito yopanga, ndikuchepetsa ndalama zogulira. Betaine imatha kulimbikitsa fungo ndi kukoma kwa nsomba ndipo imakopa nsomba nthawi zonse. Ikawonjezeredwa ku chakudya cha nsomba, imatha kuwonjezera kudya kwa nsomba, kufupikitsa nthawi yodyetsa, kuchepetsa kugwiritsa ntchito bwino chakudya, ndikulimbikitsakukula kwa nsomba.

2, DMPT (Dimethyl - β - Propionate Thiophene).

DMPTndi chokoka nsomba nthawi zonse, chomwe chimagwiritsidwa ntchito makamaka kuwonjezera pa chakudya cha nsomba, pang'onopang'ono kuwonjezera kuchuluka kwa chakudya ndi kuchuluka kwa nsomba, ndikuwonjezera kukula kwawo. Mphamvu yake yokoka ndi yabwino kuposa betaine. Asodzi ambiri agwiritsa ntchito DMPT, koma zotsatira zake sizofunika chifukwa ndi chokoka nsomba nthawi zonse chomwe chimafuna kuwonjezera kwa nthawi yayitali kuti chigwire ntchito ndipo sichiyenera kusodza. Kusodza kumafuna zokoka nsomba mwachangu, ndipo zofunikira kuti chigwire ntchito ndi "chachifupi, chosalala, komanso chachangu".

3, Dopamine mchere.

Dopa salt ndi hormone ya njala yomwe imapezeka mu nsomba za m'madzi oyera yomwe imatha kuyambitsa kukoma kwa nsomba ndikuzitumiza ku dongosolo lapakati la mitsempha kudzera mu mitsempha yolumikizana, zomwe zimapangitsa kuti nsomba zikhale ndi njala yambiri. Dopa salt ndi chothandizira chakudya cha nsomba chomwe chimagwira ntchito mwachangu komanso chothandizira njala. Pambuyo poyesa asayansi, zapezeka kuti kuwonjezera ma mililita atatu a mchere wa dopamine pa kilogalamu imodzi ya nyambo ndiyo njira yabwino kwambiri yolimbikitsira kudyetsa nsomba mukasodza carp; Mukasodza crucian carp, kuwonjezera ma mililita asanu a mchere wa dopa pa kilogalamu imodzi ya nyambo kumakhala ndi zotsatira zabwino kwambiri zolimbikitsa njala.

4, Nsomba Afa.

Alpha wa nsomba ndi cholimbikitsa nsomba, chomwe ndi chinthu chomwe chingawonjezere ntchito ya maselo a nsomba. Alpha wa nsomba ali ndi mphamvu zambiri pa ma receptor a maselo a nsomba, zomwe zimatha kuwonjezera ntchito yawo yamkati ndikupanga zotsatira zabwino kwambiri polumikizana ndi ma receptor. Nsomba zikayamba kusangalala, zimakhala ndi mphamvu zambiri ndipo zimakhala ndi chilakolako champhamvu chofuna kudya. Alpha wa nsomba ndi cholimbikitsa nsomba mwachangu, kotero ndi cha zolimbikitsa chakudya cha nsomba zomwe zimatsitsimula komanso zomwe zimagwira ntchito mwachangu.
