I-Betaine yi-glycine methyl lactone ekhutshwe kwi-beet processing by-product. Yi-quaternary amine alkaloid. Ibizwa ngokuba yi-betaine kuba yaqala yodwa kwimolasses ye-sugar beet. IBetaine ifumaneka ikakhulu kwimolasi yebhiti yeswekile kwaye ixhaphakile kwizityalo. Ingumnikeli we-methyl osebenzayo kwizilwanyana, ithatha inxaxheba kwi-methyl metabolism kwi-vivo, ingathatha indawo ye-methionine kunye ne-choline ekudleni, kwaye ineempembelelo zokukhuthaza ukutya kwezilwanyana kunye nokukhula kunye nokuphucula ukusetyenziswa kokutya.

Umgaqo wokutsala ukutya kwe-betaine kukukhuthaza ivumba kunye nencasa yentlanzi kunye ne-shrimp ngokuba nencasa ekhethekileyo kunye nokutsha okubuthathaka kwentlanzi kunye ne-shrimp, ukuze kufezekiswe injongo yokutsalwa kokutya. Ukongeza i-0.5% ~ 1.5% ye-betaine kwisondlo sentlanzi inefuthe elinamandla elivuselelayo kwiphunga kunye nencasa yazo zonke iintlanzi, i-shrimp kunye nezinye ii-crustaceans, kunye nokutsalwa kokutya okunamandla, ukuphucula i-feed palatability, ukunciphisa ixesha lokutya Ukukhuthaza ukugaywa kunye nokufunxa, ukukhawulezisa ukukhula kweentlanzi kunye ne-shrimp, kwaye ugweme ukungcoliswa kwesondlo samanzi.

I-Betaine inokukhuthaza ukukhula kweentlanzi kunye ne-shrimp, ukomeleza ukumelana nezifo kunye nokugonywa, ukuphucula izinga lokusinda kunye nesantya sokuguqulwa kwesondlo. Ukongezwa kwe-betaine kunempembelelo ebalulekileyo ekukhuthazeni ukukhula kweentlanzi ezincinci kunye ne-shrimp kunye nokuphucula izinga lokusinda. Inzuzo yobunzima be-rainbow trout etyiswa nge-betaine inyuke nge-23.5%, kwaye i-coefficient yokutya yehle nge-14.01%; Ubunzima be-salmon ye-Atlantic bunyuke nge-31.9% kwaye i-coefficient yokutya yehle nge-20.8%. Xa i-0.3% ~ 0.5% ye-betaine yongezwa kwi-compound diet ye-carp eneenyanga ezi-2, inzuzo yemihla ngemihla yanda ngo-41% ~ 49% kwaye i-coefficient feed yehla nge-14% ~ 24%. Ukongezwa kwe-0.3% ye-betaine ecocekileyo okanye edibeneyo kwisondlo kunokukhuthaza kakhulu ukukhula kwe-tilapia kunye nokunciphisa i-coefficient yesondlo. Xa i-1.5% ye-betaine iye yongezwa ekutyeni koononkala bomlambo, ubunzima bokufumana unonkala bonyuswe ngama-95.3% kwaye izinga lokusinda liye lenyuka ngama-38%.
