Kukura kwekuyedza carp mushure mekuwedzera kwakasiyana siyana kweDMPTkune chikafu chinoratidzwa muTebhu 8. Maererano neTafura 8, kudyisa carp nehuwandu hwakasiyana hweDMPTKudyisa kwakawedzera kuwedzera kuwanda kwehuremu, mwero wekukura, uye chiyero chekupona kana zvichienzaniswa nekudya chekudzora chikafu, nepo coefficient yekudya yakadzikira zvakanyanya. Pakati pavo, kuwedzera kwezuva nezuva kweY2, Y3, uye Y4 mapoka akawedzerwa neDMPT akawedzera ne52.94%, 78.43%, uye 113.73% maererano neboka rinodzora. Uremu hwekuwedzera huwandu hweY2, Y3, uye Y4 hwakawedzera ne60.44%, 73.85%, uye 98.49% maererano neboka rekutonga, uye kuwedzera kwekukura kwakawedzera ne 41.22%, 51.15%, uye 60.31% maererano. Huwandu hwekupona hwese hwakawedzera kubva pa90% kusvika 95%, uye feed coefficients yakadzikira.

Kuvandudzwa kwezvinokwezva zvemumvura

Parizvino, kune matambudziko mazhinji mukugadzirwa kwekudya kwemvura, pakati pawo matambudziko matatu akanyanya kukosha ndeaya:

1. Nzira yekupa sei kudyisa mhedzisiro yezvigadzirwa zvekudya.

2. Nzira yekupa sei kugadzikana kwechigadzirwa mumvura.

3. Nzira yekudzikisa sei mbishi uye mari yekugadzira.

Kudya kwekudya ndiyo hwaro hwekukura nekukura kwemhuka, zvigadzirwa zvechikafu zvine mhedzisiro yakanaka yekudya, yakanaka palatability, kwete chete inogona kupa chikafu chekudya, inosimudzira kugaya kwemhuka uye kutorwa kwezvinovaka muviri, inopa zvimwe zvinovaka muviri zvinodiwa pakukura nekusimudzira, asi zvakare kupfupisa zvakanyanya nguva yekudyisa, kuderedza chikafu chehove kurasikirwa nekudyiwa kwekudya.Kuona kugadzikana kwakanaka kwechikafu mumvura ndicho chiyero chakakosha chekupa mashandisirwo echikafu, kuderedza kurasikirwa kwechikafu uye kuchengetedza mvura yemadziva.

Maitiro ekudzikisa chikafu uye mutengo wekugadzira, isu tinofanirwa kudzidza nekugadzira zviwanikwa zvechikafu senge zvinokwezva zvekudyisa, kutsiva mapuroteni emhuka neprotein yezvirimwa, kuvandudza mutengo uye nhevedzano yematanho ekuyedza. In aquaculture, yakawanda chirauro haina kutorwa nemhuka kunyura pasi pemvura zvakaoma kunyatsopinzwa, kwete chete kukonzera guru tsvina, asiwo kusvibisa mvura kunaka, saka muchirauro kuwedzera kukurudzira mhuka havi zvinhu -chikafu chinokwezvakwakakosha.

Kukurudzira chikafu kunogona kukurudzira kunhuhwirira, kuravira uye kuona kwemhuka, kukurudzira kukura kwemhuka, asiwo kunopa kudzivirira kwechirwere uye kusadzivirirwa, kusimbisa physiologic hulling, kuderedza kusvibiswa kwemvura uye zvimwe zvakanakira.
