Acidifiers are mainly designed for weaned piglets as feed additive to compensate for lack of gastric acid in stomach. The research of acidifiers has a history of over 40 years. In 1960, people in feed industry found that piglet diarrhea can be relieved by organic acid. After that, simple acidifiers were used to lower pH.. read more →
Set-Accelerator refers to an additive, which can increase the mortar strength and has no significant effect on the later strength. According to the chemical composition, it is divided into two types: organic and inorganic.The organic includes Calcium Formate , Triethanolamine, Triisopropanolamine, Urea, etc. And the inorganic includes Sulfate, Chloride and so on. The effect of.. read more →

Effect of fumaric acid, calcium formate and mineral levels in diets on the intake and growth performance of newly weaned pigs The weaned pig has limited ability to acidify its stomach contents. The objective of this study (comprising three experiments) was to examine the effect of feeding diets containing fumaric acid (FA), calcium formate (CF).. read more →
