Alberto Torres (Exports Manager, Cobb-Vantress) comments on AI outbreaks as a major disruption in international breeding stock trade, especially poultry meat, during this Engormix interview.
Poultry breeding and genetic improvement became a very specialized research activity majored by a few breeding companies. These companies follow the best disease prevention biosecurity to protect their stocks. HPAI is a deadly disease that wipes out the flock in two days, and there is no way to save leave exporting the diseased chicks. Good vaccines are being manufactured to prevent the disease in lower level breeding and commercial stocks. No vaccination policy is making many flocks vulnerable to disease outbreaks and the virus multiplies in the area in large scale. Hence allowing vaccination in place of stamping out will reduce the viral load in the country.
This HPAI virus mutates very often, developing a good vaccine against it is just not possible, cross protection in mutated strains is very difficult to achieve, the breeding companies should breed for strong immune system capable of handling the virus and its mutants, and vaccine manufacturer should produce multi valent ( original virus and its mutants) vaccine for the market, Or develop birds that can resist immunosuppression of all types.
COVID also is a mutating virus. They found some technology. If we work on it I am sure a suitable technology can be evolved. Sitting with stamping out process is multiplying the virus in un vaccinated flocks much faster. The teams working with mortality flocks are at a higher risk
If we have beaten one of worst virus proteiform type so it is our best interest to syndicate a synergy to find a real targeting vaccine. Too much at stake.
All continents have been severely hit and sooner we guess we ll have a real vaccine
Stamping out flocks is not at all a solution. Maximising the RISK REDUCTION and looking forward to better utilisation of the valuable animal protein using technology might serve food security better. Will LASER BASED egg treatment along with quick testing for ensuring AI virus destruction possible ?
The main problem is not the virus but how to react to the troubles the virus can cause in the flock, whether the flock is vaccinated or not. I think we can overcome the high risk of mortality by the production of breeds that resist this virus ---and or by minimizing the causes of mortality by treating the symptoms that lead to the death of birds
Breeding resistance to each virus is time taking and expensive process. Avoid virus introduction in to your farm. It is common for all viruses. This lack of disease reduces medication and we get better productions.
