Athangudi Venugopalan I appreciate your comment. According to the OIE Terrestrial Manual, it prevents the presence of antibodies to AI by vaccination, which means that it can be vaccinated. It is recommended not to vaccinate so that the country does not lose the status of free, however, as mentioned in a previous comment (June 1) , the infection entered Mexico by a very important poultry area (7 ...

Raul Cortes I thank you for the valuable information you share with us. The TNF response is given by the infection. When the number of receptors decreases by the molt, the antigenic load decreases, which can be controlled by the immune response induced by the vaccination.

Marcos Rebollo We appreciate your kind words. Regarding his approach. Indeed that is the theory that we have. however, the bird will survive as long as it has an adequate vaccination schedule. The idea of the pelecha is to protect the reproductive tract of the bird, the vaccine is the one that protects the life of the bird.

Dr. Ramon Lopez, expert in egg production, gave the indication of pelechar and the surprise was that the birds continu ...

In the case of IA H7N3 of high pathogenicity the important thing was not mortality, it was the affectation to the reproductive system of the hen. The hens did not die but the oviduct was affected and production was never recovered.

Oscar Briceño Unless something has changed in the last decade or so, you can't. I did my PhD in methionine for pigs, and had a whole section on methionine alternatives in my first chapter. It was hypothesized that as a methyl-donor, betaine could spare methionine (itself a major methyl donor). In vitro liver homogenate trials showed some potential. However, when tested in vivo, my recollection is ...
