Sachin Patil The F-vax in the United States has changed over the years and now is very non-reactive compared to the past. in 2000, 1/4 of a dose of F-vax by water or spray would result in respiratory signs and 100% seroconversion. In 2010, a full dose of F-vax by spray produced no respiratory reaction and 30 to 40% positive seroconversion. Our producers now have gone to the eyedrop method of appli ...

Here is my assessment of the use of live Ts-11 vaccine in commercial layers: - The vaccine must be applied by eyedrop usually at 8 to 14 weeks of age. - It is delivered frozen so the cold chain must be maintained during shipment and storage at the destination before reconstitution for application. - The vaccine colonizes the upper trachea (in the cooler areas of the trachea) so the amount of resp ...

Diamond V XPC can work very well in antibiotic free broiler production in combination with probiotics and cocci vaccines. XPC can aid in preventing coccidiosis and necrotic enteritis by itself but with the addition of a good probiotic, the results are even better. Be aware that our new recommended rate for broilers since August 2014 is 1.25 kg/MT from day old to market.

Outbreaks of highly pathogenic avian influenza (HPAI serotype H5N2) appear to be slowing. Higher seasonal temperatures are helping, along with growth of vegetation – corn and soybeans growing in fields around poultry houses – which helps to reduce movement of dust carrying virus particles.However, during summer, migratory waterfowl flyways interm ...

IBV, Mg, ammonia, infectious coryza, Pasteurella, avian influenza, Newcastle can all produce the signs you describe. Antigen or pathogen detection tests need to be utilized to differentiate these diseases. For ILT diagnosis, one can also use histopathology. Finding intranuclear basophilic inclusion bodies in syncytia of the tracheal or brohchial epithelium is diagnostic for ILT.
