Zokopa nsombandi mawu otchulira okopa nsomba komanso olimbikitsa chakudya cha nsomba. Ngati zowonjezera za nsomba zili m'magulu asayansi, ndiye kuti zokopa ndi zolimbikitsa zakudya ndi magulu awiri a nsomba.

Zomwe timazitcha kuti zokopa nsomba ndi zowonjezera chakudya cha nsomba Zowonjezera chakudya cha nsomba zagawika m'magulu ang'onoang'ono owonjezera chakudya cha nsomba ndi zowonjezera chakudya chambiri cha nsomba. Athanso kugawidwa muzowonjezera kukoma kwa chakudya, zowonjezera njala, ndi zowonjezera chisangalalo. Tiyerekeza ndi kuwunika momwe zimadyetsera zokopa zingapo zamadzi am'madzi am'madzi ambiri mosiyana.

1, Betaine.

Betainendi alkaloid makamaka yotengedwa shuga beet molasses, amene angagwiritsidwe ntchito ngati chowonjezera mu chakudya nsomba m'malo methionine ndi choline mu methyl kotunga, kusintha ntchito yopanga, ndi kuchepetsa ndalama chakudya. Betaine imatha kulimbikitsa kumva kununkhiza ndi kukoma kwa nsomba ndipo imakhala yokopa kwanthawi yayitali. Akawonjezeredwa ku chakudya cha nsomba, amatha kuonjezera kudya kwa nsomba, kuchepetsa nthawi yodyetsa, kuchepetsa kudya bwino, ndi kulimbikitsakukula kwa nsomba.

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

DMPTndi chokopa cha nsomba zosatha, zomwe zimagwiritsidwa ntchito kuwonjezeredwa ku chakudya cha nsomba, kuonjezera pang'onopang'ono kuchuluka kwa madyedwe ndi mafupipafupi a nsomba, ndikuwongolera kukula kwake. Zotsatira zake zokopa ndizabwino kuposa betaine. Owotchera nsomba ambiri agwiritsa ntchito DMPT, koma zotsatira zake sizofunika chifukwa ndizokopa nsomba zosatha zomwe zimafuna kuwonjezera kwa nthawi yaitali kuti zigwire ntchito ndipo siziyenera kupha nsomba. Kusodza kumafuna zokopa mwachangu, ndipo zofunikira pakuchitapo ndi "zachidule, zosalala, komanso zachangu".

3, Dopamine mchere.

Mchere wa Dopa ndi hormone ya njala mu nsomba zam'madzi zomwe zimatha kulimbikitsa kukoma kwa nsomba ndikuzipereka ku dongosolo lapakati la mitsempha kudzera mu mitsempha ya afferent, kuchititsa njala yamphamvu mu nsomba. Mchere wa Dopa ndi wolimbikitsa chakudya cha nsomba mwachangu komanso wolimbikitsa njala. Pambuyo poyesa sayansi, zapezeka kuti kuwonjezera 3 milliliters a mchere wa dopamine pa kilogalamu ya nyambo ndiyo njira yabwino kwambiri yolimbikitsira kudyetsa pamene nsomba za carp; Mukawedza nsomba za crucian carp, kuwonjezera ma milliliters 5 a mchere wa dopa pa kilogalamu imodzi ya nyambo kumakhala ndi zotsatira zabwino kwambiri zolimbikitsa njala.

4, Nsomba Afa.

Nsomba alpha ndi nsomba stimulant, chomwe ndi chinthu chimene chingapititse patsogolo maselo a nsomba maselo. Nsomba za alpha zimakhala ndi kuyanjana kwakukulu kwa ma cell receptors, zomwe zimatha kupititsa patsogolo zochitika zawo zamkati ndikupanga zotsatira zabwino kwambiri pomanga ma receptor. Nsombazo zikasangalala, zimakhala zodzaza ndi mphamvu komanso zimakhala ndi chikhumbo chofuna kudya. Nsomba Alpha ndi chokondoweza cha nsomba chomwe chimachita mwachangu, chifukwa chake ndi cha zinthu zopatsa chidwi komanso zachangu za nsomba.
