Heat stress and performance; a matter of balance
Heat stress in animals causes a shift in blood pH that suppresses feed intake. Of course this is bad news for the animal’s performance, so optimizing the dietary electrolyte balance (dEB) is often used as a tool to manage the blood pH. The product most often used for this is sodium bicarbonate. We believe that sodium formate is equally effective at managing the dEB of feed. Last August we put this theory to the test.>>

Product Spotlight: ProSid^TM MI 700
After a few years of R&D Perstorp is now revealing its latest breakthrough in the area of mould inhibition: ProSidTM MI 700. The effectiveness of propionic acid in preservation of grain and other feed is very well known. ProSidTM MI 700 has shown the same effectiveness as propionic acid but with several key advantages such as lower evaporation, high nutritional value, reduced odour and no ADR restriction because of its low corrosiveness and high flash point.  >>

Hens at age
The optimal economic lifespan of a layer has increased significantly the past few decades due to improved breeding programs, nutrition, housing etcetera. Today's layers are productive for up to 25 more weeks than in the 1970's. Keeping layers until past their prime can be very beneficial, however, it does ask for some specific measures to assure continued productivity. >>

Perstorp on International Symposium on Digestive Physiology in Pigs
Perstorp Performance Additives participated in the eleventh International Symposium on Digestive Physiology in Pigs, held in Tarragona, Spain on 20-22 May 2009.

Acid treatment of salmonella
"De Molenaar" is a leading Dutch magazine aimed at the grain processing and feed industries. In issue number 5 of 2009 an article was printed on the suppression of Salmonella by using organic acids in the feed or drinking water. The article was written in by Perstorp's Dr. Albert van Dijk. >>
