Viral Corner

What is happening in the area today in regards to viral threats to our industry? Those major viruses being PRRSv, Swine Influenza Type A virus (IAV-S) and Swine Coronavirus (PEDv, Delta).

PRRSv: If you have been hit with PRRSv this year, it has been a struggle cleaning up. Most people were hit with a strain 1-7-4. This struck many farms causing sow mortality, abortion storms, and reproductive failure. The industry has been moving toward testing of piglets at a younger age to determine time to stability at birth. Upon knowing this, some wean down techniques have been implemented to try and clean the virus up in a more timely manner. We have seen that the sow unit environment has played an important role in clean up time. Important areas to monitor are farrowing room hygiene, castration/tail docking equipment management, how often needles are changed, and how piglet mortalities are disposed of, to name a few. The next page provides a graph showing the trend of PRRS. Continue reading “Viral Corner”

Avian Influenza

Why are we talking about avian influenza in a swine newsletter? It is important to know the effect that avian influenza may have on other species.

Recently in December 2014 and early January 2015, “USDA has confirmed several cases of highly pathogenic avian influenza (HPAI) H5 in the Pacific, Central, and Mississippi flyways (migratory bird paths). The Centers for Disease Control and Prevention considers the risk to people from these HPAI H5 to be low.” Currently, no human cases of these HPAI H5 have been reported. Additionally, avian influenza does not present a food safety risk; poultry and eggs are safe to eat. Continue reading “Avian Influenza”

Porcine Reproductive and Respiratory Syndrome (PRRSv)

Unfortunately, PRRSv has not followed the same trend as PEDv this past winter. PRRSv continues to be one of the main threats to the swine industry, and economically devastating. PRRS was first reported as “mystery swine disease” in the mid-1980s. This January and again mid-April, western Ohio sow units were hit with a 1-7-4 strain. The effects varied slightly depending on previous PRRSv history, and vaccination strategies. Current work is being done to compare these differences among the herds. Producers worked with their veterinarian on a plan for herd stability, which all included a load, close, homogenize strategy. In general, this strain of PRRSv has been associated with significant late term abortion losses, and sow deaths. Continue reading “Porcine Reproductive and Respiratory Syndrome (PRRSv)”

Swine Enteric Coronaviruses

It has been said that “the only thing constant in life is change”. As an agricultural industry, farmers are very well aware of this; it’s just how significant that change affects your bottom line. Many of these changes, such as weather, market prices, and disease introductions are out of our hands.

I hope that your spring planting season has found everyone well. So, you might ask what happened to Swine Enteric Coronaviruses this past winter compared to winter 2013. Continue reading “Swine Enteric Coronaviruses”
