Huku Zai Kukandira Decline Syndrome

Chicken egg-laying syndrome chirwere chinotapukira chinokonzerwa neavian adenovirus uye chinoratidzwa nekuderera kwechiyero chekugadzirwa kwezai, izvo zvinogona kukonzera kuderera kamwe kamwe muhuwandu hwekugadzirwa kwezai, kuwedzera kwemazai akapfava uye akaremara, uye kupenya kwemavara ebrown eggshells.

Huku, madhadha, hanzi nemallards ndiwo ari kubatwa nechirwere ichi, uye kutapurira kwemarudzi akasiyana ehuku kunokandira mazai kunosiyana, huku dzine magoko ebrown-shelled dzinokandira dziridzo dzinonyanya kubatwa nechirwere ichi. Chirwere ichi chinonyanyobata huku dzine masvondo makumi maviri nematanhatu kusvika makumi matatu nemaviri ekuberekwa, uye hachinyanyi kubatwa nepamusoro pemasvondo makumi matatu nemashanu ekuberekwa. Huku diki hadziratidzi zviratidzo mushure mekutapukirwa, uye hapana masoja ekudzivirira chirwere anoonekwa muserum, inova yakanaka mushure mekutanga kugadzirwa kwemazai. Kunobva kutapurirana kweutachiona kunyanya huku dzine utachiona, huku dzinotakura utachiona, nhiyo dzine utachiona, uye kubata tsvina nekubuda kwehuku dzine utachiona. Huku dzine utachiona hadzina zviratidzo zvekiriniki zviri pachena, mavhiki makumi maviri nematanhatu kusvika makumi matatu nemaviri ekukandira hanzi zai rekugadzira zai rakangoerekana radonha 20% kusvika 30%, kana kunyange 50%, uye mazai akatetepa-akatetepa, mazai akapfava, mazai asina goko, mazai madiki, mazai madiki, goko remazai rough kana zai magumo aive akanaka granular (sandpaper-kufanana), zai chena chinhu cheyero chakasanganiswa neropa rekune imwe nyika. Kuberekesa uye kuchechenywa kwemazai anokandwa nehuku dziri kurwara kazhinji haabatwi, uye huwandu hwehuku dzisina simba hunogona kuwedzera. Chirwere chechirwere chinogona kutora mavhiki mana kusvika gumi, mushure mezvo kuwanda kwemazai eboka kunogona kudzokera kune zvakajairika. Dzimwe huku dziri kurwara dzinogonawo kuratidza zviratidzo zvakaita sekushaikwa kwemweya, korona chena, minhenga yakaparara, kusada kudya uye kubuda ropa.

Tichifunga nezvekuunzwa kwevapfuri vanobva kunzvimbo dzisina utachiona, mapoka evapfuri akaunzwa anofanirwa kugara ari ega uye kuchengetwa ari ega, uye hemagglutination inhibition test (HI test) inofanirwa kushandiswa mushure mekukandira mazai, uye avo chete vane HI negative vanogona kuchengetwa kuti vabereke. Mapurazi ehuku uye mahoro ekuchechenya anonyatso shandisa nzira dzekuuraya hutachiona, teerera kuchengetedza chiyero cheamino acids uye mavhitaminzi mukudya. Kwemazuva 110 ~ 130 huku dzakura dzinofanirwa kubaiwa neoil adjuvant inactivated vaccine.
