Studying the pattern of traffic flows for your production site is important when designing your “bioexclusion” game plan.

ASF spreads mainly through the movement of infected pork and other animal products, as well as live animals, which includes wild boar.

Many of these tools are difficult to clean and, in many cases, they may be damaged by water, soap, and disinfectants.

The role that wild birds can play in the spreading of this infection cannot be underrated.

This study demonstrates the added profitability that air filtration can give to sow farms located in highly dense swine regions. However, it is important to point out that these figures are long term averages and not necessarily predictors for individual herds.

Among the numerous genetically distinct isolates that are identified in high pig density areas every year, only a few are able to be transmitted between herds and even less able to widely spread and dominate the entire region or system.

This study, based on some 120,000 sows, quantifies the reduction of the risk of introducing PRRS viruses when using air filtering.

In this article Salmonella critical contamination points in the abattoir will be analyzed, as well as the measures that can be taken with regard to them.

When exposed, the pigs get infected in less time than the length of the transportation and the waiting period (prior to the slaughter) in the abattoir.

It is very important to establish a series of preventive measures to prevent a worsening health status with the introduction of new serotypes.

The clinical profile seen to date of ASF in Russia and neighboring countries is a typical acute disease. The animals die between 7 and 15 days post-infection and the symptoms observed include fever, huddling together due to cold, and injuries described above.

In high-density swine regions of North America, air filtration is playing an important role in the effort to maintain PRRS free commercial sow herds

Despite its scarce use in commercial artificial insemination programs (used only in 1% of all inseminated sows) nowadays no one questions the sanitary, economic, and productive advantages of cryogenically preserved semen with respect to fresh or refrigerated semen.

Any failure in a cleaning and disinfection programme costs money. This comes from the costs of the programme, the loss of its potential benefits and very probably the costs of disease the failure has allowed to occur. It is also very disappointing for the management and staff of the farm who have done the hard work, and the veterinarian who is trying to ensure healthy efficient production.

In the last article we looked at the need for thorough complete cleaning of a building, room or equipment in any efficient biosecurity programme. If done properly this will reduce the pathogen burden hugely as shown by a typical reduction in bacterial counts by 99%.

Since 1987, Porcine Reproductive and Respiratory Syndrome virus (PRRS) has become a global drain on pig productivity, profitability, and many a producers’ morale. One thing that remains certain is PRRS virus continually finds ways to circumvent our best bio-management efforts. PRRS marches on in a ceaseless continuum of antigenic change making current vaccines and other control techniques of limited value.
