Shrimp uye kurima gakanje kunowanzo kutarisana nematambudziko akadai sekusakwana kwekudya kwekudya, asynchronous molting, uye kugara uchinetseka kwezvakatipoteredza, izvo zvinokanganisa zvakananga mararamiro ehupenyu uye kurima. Uyebetaine, inotorwa kubva kune yakasikwa shuga beet, inopa mhinduro inoshanda kune idzi marwadzo.

SezvinoitaAquatic feed additive, betaineinopa dziviriro yekukura kwakanaka kweshrimp nemakanje kuburikidza nenzira dzakawanda dzakadai sekusimudzira kudya, kukurudzira crustacean synthesis, uye kudzora osmotic pressure.

Betaineine akawanda anobatsira pa shrimp uye crab aquaculture uye yakakosha inoshanda mukuwedzera mukudya kwemvura. Basa rayo guru rinoratidzwa mune zvinotevera:

Simba rinokwezva maitiro:

Betaineine kunakidza kunotapira uye kutsva, kwakafanana nezvinhu zvinokwezva mugungwa rezvisikwa (senge glycine betaine yakapfuma muhove).

Inogona kukurudzira zvakanyanya kunhuhwirira uye kunakidza receptors ye shrimp nemakanje, zvakanyanya kuvandudza kunaka kwekudya uye kuwedzera kudya kwekudya.

Izvi zvakakosha pakuvandudza mashandisirwo echikafu nekusimudzira kukura, kunyanya panguva yekudyara kana kushushikana kwezvakatipoteredza (sekushushikana, chirwere) kuchikonzera kudzikira kwechido.

Inoshanda methyl donor:

Betaineinonyatsoshanda methyl donor mumuviri, kutora chikamu mune zvakakosha methylation maitiro. Kune makustaceans (shrimp uye crab), methylation reaction yakakosha mukuumbwa kwechitin.

Chitin ndicho chikamu chikuru che shrimp uye crab shells. Kupa mapoka e-methyl akakwana anogona kubatsira kukurudzira kunyungudika, kukurumidza kuomesa maitiro, kunatsiridza molting synchrony, uye kuwedzera chiyero chekupona.

Molting inhanho yakakosha mukukura kwe shrimp nemakanje, uye zvakare ndiyo yakanyanya kutambudzika nguva muhupenyu hwavo.

Kudzora osmotic pressure (osmotic protectant):

Betaineinoshanda organic osmotic regulator.

Kana shrimp nemakanje zvinotarisana nekushandurwa kwemunyu kwezvakatipoteredza (sekunaya kwemvura, shanduko yemvura, kuderera kwemunyu) kana kumwe kushushikana kweosmotic.

Betaineinogona kubatsira masero (kunyanya masero mumatumbo, gill nedzimwe nhengo) kuchengetedza mvura uye kuwedzera kuramba kwemuviri kune osmotic stress. Izvi zvinobatsira kuderedza kuita kwekushushikana, kuchengetedza zvakajairika physiological mabasa, uye kunatsiridza mararamiro ekupona.

Kurudzira mafuta metabolism uye kudzivirira mafuta echiropa:

Betaineinogona kukurudzira kuparara uye kutakurwa kwemafuta, kunyanya kutakura mafuta kubva pachiropa (hepatopancreas) kuenda kune tsandanyama tishu.

Izvi zvinobatsira kuderedza kuiswa kwemafuta muchiropa uye pancreas ye shrimp uye crab, uye kudzivirira kuitika kwechiropa chemafuta. Panguva imwecheteyo, kusimudzira kutakurwa kwemafuta kune tsandanyama kunogona kubatsira kuwedzera mhasuru muzana (nyama goho) uye kuvandudza nyama kunaka.

Kunatsiridza kugayiwa kwechikafu uye kubatwa:

Zvidzidzo zvakaratidza kuti betaine inogona kuvandudza kugaya uye kunwisa chiyero chezvinovaka muviri senge mapuroteni nemafuta mukudya kusvika pamwero wakati nekuvandudza nharaunda yematumbo kana kukanganisa digestive enzyme basa, nekudaro ichiwedzera kutendeuka kwekudya.

Kuwedzera kusadzivirirwa (indirect effect):Nokuwedzera kudya kwekudya, kubvisa kushushikana (kunyanya osmotic stress), nekuvandudza chiropa uye pancreas hutano (kuderedza ngozi yechiropa chemafuta).

Betaine inogona kuwedzera zvisina kunanga iyo isiri-yakananga immune immune ye shrimp nemakanje, uye kuvandudza kurwisa kwavo kune hutachiona.

Pfupiso uye mapoinzi ekushandisa mune yemvura feed:

Core function: Betaineine basa rakakosha uye rakakosha mukurima shrimp uye gakanje, iri kudya kwakanaka uye semethyl donor kusimudzira ganda synthesis uye molting.

Kuwedzera mari:Iyo yakajairika yekuwedzera huwandu mu shrimp uye crab compound feed i 0.1% -0.5% (kureva 1-5 kilogiramu patani yekudya).

Iyo chaiyo yekuwedzera mari inoda kugadziridzwa zvichienderana nerudzi rwe shrimp negakanje, nhanho yekukura, feed formula base, uye chimiro chebetaine inoshandiswa (senge hydrochloride betaine, pure betaine).

Kurudzira kutaura kune kurudziro dzevashambadziri kana kuita zviedzo zvekupfuya kuti uone iyo yakakwana dosage.
Fomu: Betaine hydrochlorideinowanzoshandiswa mukudya kwemvura nekuda kwekugadzikana kwayo, kudhura kwakaderera, uye kunyungudika kwemvura kwakanaka.
Synergistic effect:Betaine inowanzoshandiswa pamwe chete nemamwezvinokwezva(zvakadai senyucleotides, mamwe amino acids), zvinovaka muviri (zvakadai secholine, methionine, asi kuenzanisa kunofanira kuonekwa), nezvimwewo, kuti zvive nemigumisiro yakanaka.

Betaine chinhu chakanakisa chekuwedzera chine mutengo wakakwira uye mabasa akasiyana mushrimp uye gakanje chikafu chemumvura.

Inosimudzira zvinobudirirakukura, chiyero chekupona, uye hutano hwehutano hwe shrimp nemakanje kuburikidza nenzira dzakawanda dzakadai sekudya, kupa methyl, kugadzirisa osmotic pressure, nekusimudzira mafuta metabolism, iyo inokosha zvikuru pakuvandudza kushanda kwemvura.
