The influence of feed structure on the health

The influence of feed structure on the health of the GI-tract in pigs has been extensively studied in recent years in Denmark and more recently in Germany (Hannover DBIS), among others to find a relationship between particle size and the prevention of Salmonella infections. When comparing pelletised and mash feed with each other, the thermally treated (thus pelletised) feed obtains superior pig performance due to gelatinisation that takes place in the pelleting die.

In addition the pressure and temperature during pelleting also form a perfect hygienisation stage. Up to 99 percent of the natural microbial flora is eliminated. Therefore in Denmark for years it was ruled that feeds for fattening pigs had to be heated to at least 81°C during the pelleting process, so that any Salmonella would be killed.
