Potassium dicarboxylatendiyo yekutanga isiri mishonga inorwisa mabhakitiriya inokurudzira kuwedzera kwekudya kwakabvumidzwa neEuropean Union.Musanganiswa we potassium dicarboxylate uye formic acid kuburikidza ne intermolecular hydrogen bond.Inoshandiswa zvakanyanya munguruve uye kukura kupedza nguruve.Mhedzisiro yekudyisa kuyedza yakaratidza kuti kuwedzera potassium dicarboxylate pakudya kwenguruve kunogona kuwedzera zvakanyanya huremu hwenguruve uye kuderedza huwandu hwenzufu dzinokonzerwa nehutachiona hwehutachiona.Kuwedzera potassium dicarboxylate pakudya kwemombe kunogonawo kuvandudza goho remukaka remombe.

Muchidzidzo ichi, maitiro akasiyana epotassium dicarboxylateyakawedzerwa kune chikafu chepasi peprotein Penaeus vannamei, kuitira kuti iongorore inoshanda uye ine hushamwari nharaunda isina mishonga inorwisa mabhakitiriya inosimudzira mumiriri.

Zvishandiso uye nzira

1.1 yekuedza feed

Kuedza kwekudya kwekudya uye makemikari ekuongorora migumisiro inoratidzwa muTebhu 1. Kune mapoka matatu ezvokudya mukuedza, uye zviri mukati me potassium dicarboxylate ndeye 0%, 0.8% uye 1.5% maererano.

1.2 shrimp yekuedza

Uremu hwekutanga hwemuviri wePenaeus vannamei waiva (57.0 ± 3.3) mg) C. Kuedza kwakakamurwa kuva mapoka matatu ane zvinyorwa zvitatu muboka rimwe nerimwe.

1.3 nzvimbo dzekudyisa

Tsika dzeShrimp dzaiitwa mumakeji emambure ane chirevo che 0.8 mx 0.8 mx 0.8 M. ese mambure matanga akaiswa mune inoyerera inoyerera simende dziva (1.2 m kureba, 16.0 m dhayamita).

1.4 kuedza kwekudya kwe potassium fomati

Mapoka matatu ezvokudya (0%, 0.8% uye 1.5% potassium dicarboxylate) akagoverwa kuboka rimwe nerimwe mushure mekuyera 30 zvidimbu / bhokisi.Nhamba yekudya yaiva 15% yehuremu hwekutanga hwemuviri kubva pazuva 1 kusvika kuzuva 10, 25% kubva pazuva 11 kusvika zuva 30, uye 35% kubva pazuva 31 kusvika kuzuva 40. Kuedza kwakagara kwemazuva makumi mana.Kupisa kwemvura ndeye 22.0-26.44 ℃ uye salinity ndeye 15. Mushure memazuva makumi mana, uremu hwemuviri hwakayerwa uye hwakaverengwa, uye uremu.

2.2 zvabuda

Zvinoenderana nekuyedza kwekuisa density, iyo yakakwana yekuisa density yaive makumi matatu hove / bhokisi.Kupona kweboka rekutonga kwaiva (92.2 ± 1.6)%, uye chiyero chekupona kweboka re 0.8% potassium diformate raiva 100%;Nekudaro, huwandu hwekupona kwePenaeus vannamei hwakadzikira kusvika (86.7 ± 5.4)%, apo mwero wekuwedzera wakawedzera kusvika 1.5%.Iyo feed coefficient yakaratidzawo maitiro akafanana.

3 hurukuro

Muchiyedzo ichi, kuwedzera potassium diformate kunogona kuvandudza kubudirira kwezuva nezuva uye chiyero chekupona chePenaeus vannamei.Maonero akafanana akaiswa pamberi pakuwedzera potassium dicarboxylate kune chikafu chenguruve.Zvakasimbiswa kuti kuwedzera kwe0.8% potassium diformate mu shrimp feed ye Penaeus vannamei yakave nekukura kuri nani kwekusimudzira.Roth et al.(1996) yakakurudzira kuwedzera kwekudya kwekudya kwenguruve, iyo yaiva 1.8% mukudya kwekutanga, 1.2% mukudya kwekuyamwisa uye 0.6% mukukura uye kupedza nguruve.

Chikonzero nei potassium dicarboxylate inogona kukurudzira kukura ndeyekuti potassium dicarboxylate inogona kusvika kune isina simba alkaline intestinal nharaunda kuburikidza nekudyisa dumbu remhuka muchimiro chakazara, uye inongoerekana yaora kuita formic acid uye fomati, ichiratidza yakasimba bacteriostatic uye bactericidal effect, zvichiita kuti mhuka yemukati ionekwe " sterile" mamiriro, zvichiratidza kukura kusimudzira maitiro.
