1,2-Propandiol USP
1,2 Propandiol (propylene glycol) is a feed additive used for multiple purposes. In 1999, 1,2 ÂPropandiol was released within the EU for use as an energy-rich animal feed. It is now mainly used in feed for ruminants, particularly dairy cattle. In the first 100 days of their lactation period, dairy cattle frequently suffer from extreme energy deficiency due to a lack of substrate for glyconeogenesis.
