Izinto ezitsala iintlanziligama eliqhelekileyo lezinto ezitsala iintlanzi kunye nezinto ezikhuthaza ukutya kweentlanzi. Ukuba izongezo zeentlanzi zihlelwe ngokwesayensi, ngoko izinto ezitsalayo kunye nezinto ezikhuthaza ukutya ziindidi ezimbini zezongezo zeentlanzi.

Oko sidla ngokukubiza ngokuba zizinto ezitsala iintlanzi zizizinto ezikhuthaza ukondliwa kweentlanzi. Izinto ezikhuthaza ukutya kweentlanzi zahlulwe zibe zizizinto ezikhuthaza ukutya kweentlanzi ezisebenza ngokukhawuleza kunye nezikhuthaza ukutya kweentlanzi ezingapheliyo. Zinokwahlulwahlulwa zibe zizizinto ezikhuthaza ukutya eziphucula incasa, ezikhuthaza indlala, kunye nezikhuthaza uvuyo. Siza kuthelekisa size sihlalutye iziphumo zokutya zeentlobo ngeentlobo zezitsala iintlanzi zamanzi acocekileyo ngokwahlukeneyo.

1, iBetaine.

I-Betaineyi-alkaloid ekhutshwa kakhulu kwi-sugar beet molasses, engasetyenziswa njengesongezelelo kwi-fish feed ukuze ithathe indawo ye-methionine kunye ne-choline ekunikezelweni kwe-methyl, iphucule ukusebenza kwemveliso, kwaye inciphise iindleko zokutya. I-Betaine inokukhuthaza imvakalelo yevumba kunye nencasa kwiintlanzi kwaye inomtsalane weentlanzi ongapheliyo. Xa yongezwa kwi-fish feed, inokunyusa ukutya kweentlanzi, inciphise ixesha lokutya, inciphise ukusebenza kakuhle kokutya, kwaye ikhuthazeukukhula kweentlanzi.

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

I-DMPTyintlanzi ehlala itsala iintlanzi, esetyenziswa kakhulu ukongezwa ekutyeni kweentlanzi, inyusa kancinci inani lokutya kunye nokuphindaphinda kweentlanzi, kwaye iphucula izinga lokukhula kwazo. Isiphumo sayo esitsalayo singcono kune-betaine. Abalobi abaninzi basebenzise i-DMPT, kodwa isiphumo asibalulekanga kuba yintlanzi ehlala itsala iintlanzi efuna ukongezwa ixesha elide ukuze isebenze kwaye ayifanelekanga ukuloba. Ukuloba kufuna izinto ezitsala ngokukhawuleza, kwaye iimfuno zesiphumo "zimfutshane, zithe tyaba, kwaye ziyakhawuleza".

3, ityuwa yeDopamine.

Ityuwa yeDopa yihormone yendlala kwintlanzi zamanzi acocekileyo enokuvuselela incasa yentlanzi kwaye iyidlulisele kwinkqubo yemithambo-luvo ephakathi ngemithambo-luvo ehambelana nayo, nto leyo ebangela indlala enamandla kwintlanzi. Ityuwa yeDopa ikhuthaza ukutya kwentlanzi ngokukhawuleza kwaye ikwakhuthaza indlala. Emva kovavanyo lwesayensi, kufunyenwe ukuba ukongeza iimililitha ezi-3 zetyuwa yedopamine ngekhilogram yebait yeyona ndlela isebenzayo yokukhuthaza ukondla xa uloba i-carp; Xa uloba i-crucian carp, ukongeza iimililitha ezi-5 zetyuwa yeDopa ngekhilogram yebait kunempembelelo engcono yokukhuthaza indlala.

4, intlanzi i-Afa.

I-Fish alpha sisivuseleli seentlanzi, into enokuphucula umsebenzi weemolekyuli zeeseli zeentlanzi. I-Fish alpha inomdla ophezulu kwii-receptors zeseli zeentlanzi, ezinokuphucula umsebenzi wazo wangaphakathi kwaye zivelise iziphumo eziphezulu ngokuzibophelela kwii-receptors. Emva kokuba iintlanzi zivuyile, ziya kuba namandla kwaye zibe nomnqweno onamandla wokutya. I-Fish Alpha sisivuseleli seentlanzi esisebenza ngokukhawuleza, ngoko ke siyinxalenye yezivuseleli zokutya kweentlanzi ezivuselelayo nezikhawulezayo.
