1 Zvishandiso uye Nzira

1.1 Zvishandiso zvekuyedza uye hove dzekuyedza
S. S' - Dimethylacetic acid thiazole (DMT), DMPT
Iyo carp yekuyedza yakatorwa kubva kupurazi re aquaculture, ine miviri ine hutano uye zvakatsvinda zvakatemwa. Kuedza kusati kwatanga zviri pamutemo, hove dzekuyedza dzichasimudzwa kwenguva pfupi murabhoritari kwemazuva manomwe, panguva iyo dzinozopihwa chikafu checarp chinopihwa nefekitori yekudya.
1.2 Zvekudya zvekuyedza
1.2.1 Lure test feed: Pwanya chikafu checarp chinopiwa nefekitari yefekitari, wedzera huwandu hwakaenzana hweA-starch, sanganisa zvakaenzana, uye sanganisa nehuwandu hwakakodzera hwemvura yakasvibiswa kuti uite 5g inonamira mabhora ega ega sekudya kweboka rekutonga. Panguva imwecheteyo, gadzira chikafu chekudya nekutanga kupwanya chikafu checarp, uchiwedzera huwandu hwakaenzana hwealpha starch, uye kuwedzera chirauro DMT uye.DMPTpazvikamu zviviri zve 0.5g/kg uye 1g/kg, zvichiteerana. Sanganisa zvakaenzana uye sanganisa nehuwandu hwakakodzera hwemvura yakasvibiswa kuita 5g yega yega bhora rinonamira.
1.2.2 Kukura bvunzo feed:

Dzvanya chikafu checarp (kubva panzvimbo imwechete sepamusoro) kuita upfu, upfuure nemusefa makumi matanhatu, wedzera huwandu hwakaenzana hwealpha starch, sanganisa zvakakwana, sanganisa nemvura yakashambidzwa, svina kubva musefa kuita magranules, uye woimisa nemhepo kuti uwane chikafu cheboka rekudzora bvunzo yekukura. The synthesizedDMTuye makristasi eDMPT akanyungudutswa mumvura yakanyungudutswa kuti agadzirire mhinduro yehutano hwakakodzera, iyo yakashandiswa kusanganisa zvakakwana zvakasanganiswa chikafu checarp uye starch mumagranules. Mushure mekuoma, kudya kweboka rekuedza kwakawanikwa, neDMTuye DMPT yakawedzerwa mumatatu ekugadzirisa magiradhi e0.1g/kg, 0.2g/kg, uye 0.3g/kg, zvichiteerana.

1.3 Nzira yekuedza
1.3.1 Muedzo wekukwezva: Sarudza 5 experimental carp (ine avhareji huremu hwe30g) sehove yekuyedza. Pamberi pekuyedzwa, nzara kwemaawa makumi maviri nemana, uye woisa hove yekuyedza mugirazi yemvura (ine saizi ye40 × 30 × 25cm). Chikafu chekukwevesa chinoiswa chinhambwe che5.0cm kubva pasi pemvura yakadzika uchishandisa tambo yakamiswa yakasungirirwa pabhawa yakachinjika. Hove inoruma chirauro uye inodedera tambo yacho, iyo inotumirwa kubhawa yakachinjika yorekodhwa nechirekodha chevhiri. Kuwanda kwekurumwa kwechirauro kunoverengerwa zvichibva pakudedera kwepamusoro kwehove shanu dzekuyedza dzichiruma chirauro mukati memaminitsi maviri. Muedzo wekudya weboka rimwe nerimwe rekudya wakadzokororwa katatu, uchishandisa ichangobva kugadzirirwa kudyisa mabhora ekunamatira nguva imwe neimwe. Nekuita zviedzo zvakadzokororwa kuti uwane huwandu hwese uye avhareji frequency yebhaiti, iyo yekudyisa mhedzisiro yeDMTuye DMPT pane carp inogona kuongororwa.

1.3.2 Kuedza kwekukura kunoshandisa 8 magirazi emvura (saizi 55 × 45 × 50cm), ine kudzika kwemvura kwe40cm, tembiricha yemvura chaiyo, uye inflation inoenderera. Hove dzekuyedza dzakapihwa zvisina tsarukano uye dzakakamurwa kuita mapoka maviri ekuedza. Boka rekutanga rine ma aquariums mana, akaverengwa X1 (control group), X2 (0.1gDMT/kg feed), X3 (0.2gDMT/kg feed), X4 (0.3gDMT/kg feed); Rimwe boka re 4 aquariums, nhamba Y1 (control group), Y2 (0.10g DMPT/kg feed), Y3 (0.2g DMPT/kg feed), Y4 (0.30g DMPT/kg feed). 20 hove pabhokisi, inodyiswa katatu pazuva pa8: 00, 13:00, uye 17:00, nehuwandu hwekudya hwezuva nezuva hwe5-7% yehuremu hwemuviri. Kuedza kwakatora mavhiki matanhatu. Pakutanga uye pakuguma kwekuedza, huremu hwakanyorova hwehove yekuedza hwakayerwa uye chiyero chekupona kweboka rimwe nerimwe chakanyorwa.

2.1 Mhedzisiro yekudyisa yeDMPT uyeDMTpa carp
Mhedzisiro yekudyisa yeDMPT uyeDMTpamusoro pecarp inoratidzwa nehuwandu hwekuruma kwehove yekuedza panguva yekuedza kwemaminiti e2, sezvakaratidzwa muTebhu 1. Kuedza kwakawana kuti mushure mekuwedzera DMPT uye DMT feed ku aquarium, hove yekuedza yakakurumidza kuratidza kushingaira kwekudya kwekudya, apo painoshandisa boka rekutonga kudya, maitiro ehove yekuedza yakanga isinganyanyi kunonoka. Kuenzaniswa nekudzora chikafu, hove dzekuyedza dzaive nekuwedzera kukuru muhuwandu hwekuruma chikafu chekuyedza. DMT uye DMPT zvine zvakakosha zvinokwezva mhedzisiro pakuyedza carp.

Kuwedzera uremu, kuwedzera kwekukura kwekukura, uye mararamiro ekupona kwecarp akadyiswa nezvikamu zvakasiyana zveDMPT zvakawedzera zvakanyanya kuenzaniswa neavo vakadyiswa nekutonga kwekudya, asi chikafu chekudya chakaderedzwa zvakanyanya. Pakati pavo, kuwedzerwa kweDMPT kuT2, T3, uye T4 kwakawedzera kuwedzera kwezuva nezuva kwemapoka matatu ne52.94%, 78.43%, uye 113.73%, maererano, zvichienzaniswa neboka rinodzora. Uremu hwekuwedzera huwandu hweT2, T3, uye T4 hwakawedzera ne 60.44%, 73.85%, uye 98.49%, pamwe chete, uye kuwedzera kwekukura kwakawedzera ne 41.22%, 51.15%, uye 60.31%, maererano. Huwandu hwekupona hwakawedzera kubva pa90% kusvika 95%, uye feed coefficients yakaderera ne28.01%, 29.41%, uye 33.05%, zvichiteerana.

3. Mhedziso

Mukuedza uku, kanaDMTkana DMPT yakawedzerwa, kuwanda kwekudya, kuwedzera kwekukura kwekukura, uye kuwedzera kwezuva nezuva kwehove yekuedza muboka rimwe nerimwe yakawedzerwa zvakanyanya kana ichienzaniswa neboka rinodzora, asi chidimbu chekudya chakaderera zvikuru. Uye kana iri DMT kana DMPT, kukura kwekusimudzira kunowedzera kukosha nekuwedzera kwehuwandu hwekuwedzera muzvikamu zvitatu zve 0.1g / kg, 0.2g / kg, uye 0.3g / kg. Panguva imwecheteyo, kuenzanisa kwekudya uye kukura kwekusimudzira migumisiro yeDMT neDMPT yakaitwa. Yakawanikwa kuti pasi pehutano hwakafanana hwebvudzi, kuwanda kwekudya, kuwedzera kuwanda, uye kuwedzera kwekukura kwehove yekuedza muboka rekudya reDMPT yakawedzera zvakanyanya kana ichienzaniswa neboka reDMT rekudya, nepo chidimbu chekudya chakaderedzwa zvakanyanya. Zvichienderana nekutaura, DMPT ine mhedzisiro yakakosha pakukwezva nekusimudzira kukura kwecarp kana ichienzaniswa neDMT. Ichi chiedzo chakashandisa DMPT uye DMT yakawedzerwa kune carp feed kuti iongorore kudya kwavo uye kukura kwekusimudzira mhedzisiro. Mhedzisiro yacho inoratidza kuti DMPT neDMT vane tarisiro yakakura yekushandisa sechizvarwa chitsva chezvinokwezva mhuka dzemumvura.
