Preventing Newcastle Disease with the avinew vaccine
This video demonstrates the benefits of vaccinating your chickens with the Avinew Vaccine to prevent Newcastle Disease. However, study results were quite revealing. See below the video.
Study Results on Avinew Vaccine for the Prevention of Newcastle disease
Studies on Avinew Vaccine revealed that it was successful and gave 100% protection from Newcastle disease itself but did little to protect against infection and replication of the viruses because many birds who appeared to be healthy otherwise, still had gross lesions. " Six groups of 10-day-old, specific pathogen-free chickens were vaccinated with doses of 10(3.0), 10(4.5) and 10(6.0) EID50 of Avinew vaccine and challenged at 4 weeks of age intramuscularly at a dose of 10(5.3) EID50/0.2 ml/bird of GPMV and RCV.
No statistically significant difference could be found in the protection offered by Avinew vaccine against GPMV as compared to RCV challenge.
The protection offered against the ND challenge was found to be dose dependent. At the recommended field dose of 10(6.0) EID50 the vaccine gave 100% protection from mortality against both the challenge viruses, but not against infection and replication of the viruses, as gross lesions were evident even in apparently healthy birds that survived the challenge. The protective dose (PD90) of the Avinew vaccine against GPMV challenge was calculated at 10(4.38) and against that of RCV at 10(4.43)" (Bwala DG, e. 2019)..

- Labored breathing (gasping)
- Facial swelling
- Paralysis
- Trembling
- Twisting of the neck (sign of central nervous system involvement)
- Eat less feed
- Drink less water
- Significant drop in egg production..
