Live Salmonella typhimurium (LVST) and E. coli (LVEC) vaccines have been widely used across the poultry industry as successful measures of controlling colibacillosis and salmonella, respectively. Both products are applied by mass administration, either by spray or water. This results in high mucosal exposure to the vaccine, which induces immunity mostly driven by cellular and IgA immunity. A seque ...

AL2 is the most prevalent IBD virus in U.S. broilers, accounting for as much as half of today’s field isolations. The newest recombinant rHVTIBD vaccine was introduced in 2021. Previous studies in broilers with no IBD maternal antibodies showed this vaccine gave high levels of protection (70-78%) against AL2 challenge by 18-19 days. This paper will present 2 studies conducted to measure AL2 ...

However, vaccination may be accompanied by some adverse effects, such as a negative impact on growth and/or the development of necrotic enteritis.

In particular, I have experience in the use of air traps in the spaces where the EVAPORATIVE PANELS go, and supplementing with a line of micro sprinklers (FOGGERS).

Thank you for your question.
My comment was meant to highlight the fact that these are all live coccidiosis vaccines that work through a similar process of initial infection, followed by subsequent reinfection until immunity is developed in the host. Many companies have made changes to how their live coccidiosis vaccine is applied (through new equipment or application methods) or formulated (thr ...
