Propylene glycol is a clear, moderately viscous liquid that dissolves well in water and many organic solvents. It offers high chemical purity and remains stable across a wide range of temperatures. With a high boiling point of around 188°C and a freezing point as low as -59°C, it is exceptionally resistant to fluctuations during transport and storage.

Feed-grade glycol is known for its low toxicity and high bioavailability. With a neutral pH, it does not affect the structure or taste of other components in the feed mix. Its naturally sweet flavor improves the palatability and uptake of the product by animals. Thanks to its chemical stability and resistance to degradation, propylene glycol for animal feed retains its properties even during long-term storage.

In dairy cattle nutrition, feed-grade glycol plays a crucial role during the first weeks after calving, when the animals’ energy requirements increase sharply. Administering glycol during this period effectively helps prevent negative energy balance – a primary cause of both clinical and subclinical ketosis. Regular supplementation improves cows’ metabolic balance, increases appetite, supports milk production, and positively impacts reproductive performance. Moreover, properly managed supplementation can significantly shorten the time needed for animals to return to full fertility after calving.

Beyond dairy cattle, propylene glycol is also used in the nutrition of other livestock species, such as sheep and goats – particularly during periods of increased energy demand related to pregnancy, lactation, or rapid growth. In some species, glycol supplementation is even considered a key part of preventing pregnancy toxemia (ketosis), a condition that can lead to serious losses within the herd.

Propylene glycol for animal feed is a valued additive in modern livestock farming, helping to improve animal health, productivity, and the overall profitability of animal production.
