The main mechanism of defense against intracellular infections, particularly virus.

In most fattening herds, the biggest risk for the finisher pigs to become infected with Salmonella is the within-farm contamination cycle of Salmonella. The biggest risk for introduction of Salmonella is buying infected piglets.

From September 12 to 15 took place the 30th edition of SPACE. Visit our photo gallery.

Although the seasonal fall in prices in the US is normal at this time of the year, prices have been really low in recent days. In fact, we have to go back to 2009 to find prices below the current ones. The sharp fall in belly primal price and the increase in slaughter weight in recent weeks are some of the reasons of such drop.

Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission.

Community legislation on veterinary medicinal products and medicated feed is currently being reviewed with the aim of contributing to the reduction of antimicrobial resistance. The points of debate of these regulations are...

Weaning stress accompanied by outburst of aggression is a critical point in pig production as it compromises piglets’ welfare and leads to poor growth rate and health problems. Therefore, a weaning methods to smoothen the lactation–weaning transition are of great importance.

The role of each player in the innate immunity response: Type 1 Interferons and pro-inflammatory cytokines, complement, acute phase proteins, antimicrobial proteins, phagocytes, NK cells, γ/δ T lymphocytes,...

This article helps us to define the minimum biosecurity measures that should be internally established to prevent indirect PEDv transmission.

Guided interventions as a team effort of farmer and herd veterinarian/other advisors have shown to be a promising method in the reduction of antimicrobial usage in pig production.

Influenza A viruses (IAVs) are endemic in swine and represent a public health risk. However, there is limited information on the genetic diversity of swine IAVs within farrow-to-wean farms, which is where most pigs are born.

When productivity decreases, but productive efficiency is maintained...

The effect of dietary fats differing in fatty acid (FA) composition on the metabolism of saturated FA (SFA) and monounsaturated FA (MUFA) in growing pigs was investigated.

The α-ketoglutarate supplementation may affect intestinal microbiota promoting SCFA production in the intestine.

Here, we describe the PRRS epidemic in Chile between October 2013 and April 2015, and we studied the origins and spread of PRRSV throughout the country.

This article shows the different measures taken and the strategy followed to eradicate PEDv in a commercial farm: stabilization, creation of a disinfection bubble, monitoring and verification.

This second part on AI stud management reviews the procedure for calculating sperm concentration and the elements that affect a correct assessment.

While the remainder of the year will likely have challenges a little deeper than most are thinking now, it is not looking like a disaster…

The development of piglet immune system under vaccination against PRRSV it is not improved by the use of probiotics and prebiotics or colostrum.

Global Consumer Trends and the Opportunity for American Agriculture - Dr. Mark Lyons, Global Vice President & Head of Greater China, Alltech, from the 2017 NIAA Annual Conference, U.S. Animal Agriculture's Future Role In World Food Production - Obstacles & Opportunities, April 4 - 6, Columbus, OH, USA.

It is difficult for a single additive to mimic the effect of the addition of antibiotics or ZnO. This is why we need to combine groups of additives in water and feed, so they act both, as prevention and treatment.

High feeding level during the wean-to-oestrus may increase farrowing rate but also may increase stillborn rate and reduce piglet birth weight.

Liquid manure in deep anaerobic storage, contains sulfur (from amino acids in feed, manure or in water) which certain bacteria (anaerobes) use as a substitute for oxygen. They produce H₂S as an end product, which is toxic to living tissue, by stopping the energy supplying reactions in the tissue cells.
