Avian influenza critical challenge for poultry industry
Avian Influenza is a critical challenge for the industry as it caused the greatest losses in Canada and the USA (H5H7) between 2013 and 2015. In Mexico and Central America, there were outbreaks of H5N2 and H7N3; while in Chile, H7N3, H1N1 and H4 were present, said Dr. Guillermo Zavala of Avian Health International during his presentation at the 2016 International Production & Processing Expo (IPPE). The program was presented entirely in Spanish.
In his presentation on Emerging Diseases in the American Continent, Zavala observed that avian influenza (AI) circulates mainly among wild birds in lake areas. It is also transmitted via insufficient biosecurity measures and infrastructure errors. Zavala remarked that vaccines do not eradicate AI, but help to prevent the virus, and preventive measures need to be accompanied by biosecurity.
Zavala also discussed other diseases, such as erysipelas, infectious bronchitis, infectious laryngotracheitis and mycoplasma, which are making an appearance again in commercial poultry. He remarked that they are less common thanks to increased biosecurity measures. However, they are still around.
Dr. Arturo García of Akey Nutrition talked about “Evaluating New Technology in Formulating Broiler Feed”. He said new technology should be used depending on the company’s objective and the specific problem to be solved. Available information should be considered, and if there is no data, it should be generated with controlled tests or consistent field tests, repeated several times.
García added that to consider a new nutritional technology, a company must take into account a better feed conversion rate, a study of the cost of feed per pound of meat, a better carcass yield, or the aim to place the product in a special market.
