Ngesikhathi sokufuywa kwezimfanzi eNingizimu Melika, abalimi abaningi bathola ukuthi izimfanzi zabo zidla kancane futhi azikhuli inyama.Siyini isizathu salokhu?Ukukhula kancane kwezimfanzi kungenxa yembewu, ukudla kanye nokuphathwa kwezimfanzi ngesikhathi senqubo yokufuywa kwezilwane zasemanzini.I-Potassium diformateingaxazulula inkinga yokudla kancane kanye nokuntuleka kokukhula kwenyama ekulimeni kwezimfanzi.Abanye abafuyi babike ukuthi badla ukudla okwejwayelekile ngenyanga yokuqala kodwa bengadli kakhulu ngenyanga yesibili okwenza abalimi abaningi bacabange ukuthi kuyinkinga kulolo bese besola ukuthi izinga eliphansi lokudla lidala ukwehla kwezinga lokudla. isifiso sokudla nezimfanzi kanye noshintsho ohlotsheni lokudla.Ngenxa yalokho, isimo sokudla kancane asizange sibe ngcono, futhi amanye amachibi aba bucayi nakakhulu.

Ngokusekelwe kulezi zinkinga, izizathu zokusetshenziswa kancane kwezimfanzi zaseNingizimu Melika zingafingqwa ngale ndlela elandelayo:

1. Isizathu sembewu yezimfanzi:

Enye imbewu ye-shrimp inobukhulu obuhlukahlukene ngokwemvelo, futhi ukukhula kwayo kuzohluka ngesikhathi sokutshalwa kamuva.Kukhona nembewu yezimfanzi evela emithonjeni ehlukene, evame ukukhula kancane noma iyeke ukukhula esigabeni sakamuva.

2. Izinga lamanzi:

Amazinga aphezulu e-ammonia nitrogen, i-nitrite, ne-pH emanzini angabangela izinguquko ze-pathological kuma-shrimp aseNingizimu Melika, ngaleyo ndlela athinte ukudla kwazo.

3. Kunamagciwane amaningi echibini:

ingahlinzeka ngezilwane eziningi zokudoba izimfanzi, futhi inqubo yokudla izohamba kancane ngalesi sikhathi.

4. Izinto zokuphatha:

Ukuminyana kwesitoko esikhulu, izinga lamanzi angashoni, ukushintshana kwamanzi okunganele, kanye nokudla okunganele (okuvame ukulawulwa ku-6-8% wesisindo somzimba) konke kungabangela ukuphakelwa kancane kwezimfanzi.

 

Ngaphezu kwalezi zici ezingenhla ezibangela ukudla kancane kwezimfanzi, kukhona nezifo ezibangelwa amagciwane kanye negciwane.Ama-shrimp anezifo azodla kancane kancane.

Umphumela we-potassium diformate ekusebenzeni kokukhiqizwa kwezimfanzi zaseNingizimu Melika:

I-Potassium diformateinganciphisa izinga le-enteritis e-Penaeus vannamei.I-Potassium diformate ayikwazi nje ukuthuthukisa ukungena kwamathumbu emathunjini, ikhuthaze ukugayeka kokudla kanye nokumuncwa kwamaprotheni, ikhuthaze ukukhula kwezimfanzi, kodwa futhi ikhuthaze ukoloni nokwanda kwamabhaktheriya anenzuzo emgudwini wamathumbu, ivimbele amagciwane ayingozi emathunjini, ilawule i-PH emathunjini. amapheshana, akhuthaze ukuthuthukiswa kwamathumbu, alondoloze impilo yamathumbu emfucumfucu, anciphise kakhulu izinga le-enteritis e-Penaeus vannamei, athuthukise kakhulu ukuzivikela kwezimfanzi, akhulise ukumelana nezifo kwezimfanzi, futhi athuthukise ubungqabavu bezimfanzi.Umphumela wokwengeza amazinga ahlukene e-potassium diformate ukuze udle ekusebenzeni kokukhiqizwa kwezimfanzi ezimhlophe zaseNingizimu Melika.Ukwengeza u-0.8% we-potassium diformate ekudleni kukhuphule isisindo esiphelele sezimfanzi ezimhlophe zaseNingizimu Melika ngo-20.6%, isisindo sansuku zonke sazuza ngo-26%, kanye nezinga lokusinda ngo-7.8%.Imiphumela yokuhlolwa ibonisa ukuthi ukungeza izinga le-potassium diformate elingu-0.8% ekudleni kwezimfanzi ezimhlophe zaseNingizimu Melika kungathuthukisa kakhulu ukukhula kwezimfanzi futhi kwandise izinga lokusinda kwazo.

Umsebenzi oyinhloko we-potassium diformate ukuba nemiphumela elwa namagciwane kanye ne-bactericidal, engathuthukisa ukumelana nezifo zama-shrimp futhi ithuthukise ukuqina kwawo ngokomzimba.Izingxenye eziyinhloko zei-potassium diformateingalawula ukwakheka kwe-microbiota yamathumbu futhi igcine ibhalansi ye-microbiota yamathumbu, engathuthukisa ukungena kwamathumbu ezimfanzi, ikhulise umsebenzi wama-protease, ikhulise ukugaya kanye nokusetshenziswa kwamaprotheni okuphakelayo, inciphise isilinganiso sokudla, ithuthukise isimo sokudla kwezimfanzi, futhi ukhuthaze ukukhula kwezimfanzi.
