2.Nzira yekufema ndiyo inonyanya kupiswa mushure mekudzivirira;

3.Iyo antibody titer haina kuenzana, mwero wekudzivirira hauna kunaka, saka huku dziri nyore kurwara;

4.The immune blank nguva yakareba, kudzivirira kwemuchinjikwa kwakaderera, uye chirwere chichiri kuitika mushure mekudzivirira;

5.Mabroilers pazera remazuva makumi maviri haabaiwe nhomba yechirwere cheNewcastle.Paive nematambudziko mazhinji muchikamu chekupedzisira uye mutengo wezvinodhaka wakakwira;

6.Chirwere chacho chiri kuramba chichiwedzera kuoma kurapa.Kazhinji kacho mishonga yepamusoro-dose haigone kuita zvinotarisirwa.

Ichi chigadzirwa chinogona:

1. kusimudzira kukura kwenhengo dzemuviri, kuvandudza kudzivirira kwechirwere uye kuderedza kufa.

2. Zadza nguva isina chinhu yekudzivirira kweNDV, wedzera antibody titer uye kuderedza chiitiko.

3. kurapwa kwezvirwere zvakasiyana-siyana, kupfupisa nguva yavo yekudzorera uye kuwedzera hupfumi.
