Poultry vaccines
Disease prevention by vaccination is an integral part of flock health management protocols. Active immunization using live vaccines is the current industry standard. Routinely used vaccines in chickens include MDV, NDV, IBV, and IBDV, and in turkeys NDV and HEV. Newer vaccines, including molecular recombinants in which genes of immunogenic proteins from infectious agents are inserted into a live viral vector, are also being examined for commercial use. Efforts are under way to enhance vaccine efficacy by the use of adjuvants, particularly cytokines. The vaccine delivery systems include in ovo injection, aerosol, spray, drinking water, eye drop, and wing web injection. The in ovo vaccination procedure is relatively new and at the present time it is used primarily to vaccinate broiler chickens against MDV. Birds respond to vaccines by developing humoral and cellular immune responses. There are two main types of vaccine available for poultry: live or killed.

Although plants and animals began to be acquired as domesticants nearly 10,000 years ago, it has only been the last 50 years in which animals have been intensively raised for food. In 1892 Wehman wrote “Poultry, to be successful on a large scale must be kept in small colonies of about 50 birds, for many more than that number in a single house is apt to cause sickness or disease ere long among”. Given the scale and concentration of the modern poultry industry, one must ponder whence we have...

Because of the threat of a pandemic flu, possibly from avian influenza, authorities world wide are increasing their stocks of flu vaccine. Today’s flu vaccines are developed in fertile chicken eggs. The eggshell is cracked, and the influenza virus is injected into the fluid surrounding the embryo.
The egg is resealed, the embryo becomes infected, and the resulting virus is then harvested, purified and used to produce the vaccine. Because of the large demand of flu vaccines, there is a...

Egg producers now have access to a new tool developed by the Agricultural Research Service that helps protect laying flocks from serious diseases like infectious bronchitis, mycoplasmosis and exotic Newcastle disease. Each year, mycoplasmosis alone costs U.S. producers more than $140 million, partly due to uneven vaccine delivery.
Vaccines are currently dispensed to egg-laying leghorn chickens as an inhalable mist sprayed inside poultry houses. The applicator consists of a hose attached to...

Vaccines would only be used to immunise fighting cocks, domestic poultry, expensive birds and free-range ducks, while chickens and ducks raised for export would not be vaccinated.
Approval came during a three-hour meeting of the anti-bird flu committee chaired by Prime Minister Thaksin Shinawatra, who last week put the talks on hold for a week to give him...
