Propylene glycol is used in animal feed. Propylene glycol is a colorless, odorless liquid that may be obtained from oil, natural gas, or plant sources. It is commonly used for industrial air conditioning, cooling, process heating and antifreeze. It improves the freezing and thawing stability of products. It is also a solvent, moisturizing and to some extent enhancing penetration. There are two main types of glycol, ethylene glycol and propylene glycol, which are available in the industrial and food categories.
Ethylene glycol is commonly used in cases where performance is important and due to the chemical toxicity of ethylene glycol, there is no human or animal contact. It can be found in high concentrations in “pet” products. Because it has a wider safety margin than ethylene glycol, it is commonly used to absorb excess water and retain moisture in some medications, cosmetics, or dog and human products. It is classified by the FDA as GRAS (generally known as safe). It is also used as a solvent for food colors, flavorings and medications (such as injectable diazepam).
In 1999, propylene glycol was released in the European Union for use as animal feed. It is now mainly used in ruminant feed, especially dairy cows. During the first 100 days of lactation, dairy cows often suffer from severe energy deficiency due to a lack of litter for glycogenogenesis. Propylene glycol in animal feed can be useful for boosting the energy of pig and poultry feed and can also be used as a preservative for dog food. It has long been used in beef feed to improve negative energy balance.
In the two weeks before delivery and at the beginning of breastfeeding, the use of propylene glycol has been proven to be very effective as part of a proper nutrition strategy. Propylene glycol is widely used due to its special effect in preventing ketosis and stabilizing metabolism. Especially in early lactation, the use of propylene glycol reduces the concentration of ketone bodies in the blood, milk and urine.
This special effect of propylene glycol can be explained by its direct conversion to oxaloacetate, resulting in the rapid elimination of the frequently occurring oxaloacetate deficiency. Oxaloacetate is very important in the energy metabolism of cows. Thus, propylene glycol supports the ketone body by supporting less metabolism in the liver and reduces the risk of ketosis. Other side effects such as fever, placental problems and mastitis are less likely to occur as a result. Also, the use of propylene glycol directly leads to a higher concentration of glucose in the blood this is a Applications of monopropylene glycol.

The purity of propylene glycol for animal feed is 99.7%, which helps to provide high quality, consistent and cost-effective performance in feed applications. It is characterized by exceptional stability, high heat and boiling point, low vapor pressure and extensive solubility. Cats are sensitive to propylene glycol and can no longer be used in cat food. It can cause poisoning if cats or dogs consume large amounts of propylene glycol. This is usually seen when consuming pets with high concentrations of liquid propylene glycol products.
