5 facts about alpha-monolaurin

Monoglycerides are highly effective against pathogens and fortify body defence mechanisms of livestock animals. Specifically alpha-monolaurin possesses unique properties, enabling it to stimulate animal health via multiple actions.

1. Virus control

Alpha-monolaurin is gaining more interest in the fight against various viral diseases because of its ability to destroy the fat-envelope. Several in vitro trials reveal that the anti-viral effect of alpha-monolaurin outperforms glycerides of other medium-chain fatty acids (MCFAs). Globally, alpha-monolaurin is applied to suppress the negative impact of Marek’s disease, Newcastle disease, infectious bronchitis, avian influenza and others.

2. Bacteria control

MCFAs show antibacterial properties, especially against Gram-positive bacteria. MCFAs are therefore an interesting alternative for Antibiotic Growth Promotors (AGPs). Alpha-monolaurin, a glyceride of MCFAs, is showing even stronger antibacterial properties than free MCFAs. As a result, it improves animal health and performance when applied to the diet of livestock animals. Above that, pathogens do not develop resistance against alpha-monolaurin. Which makes it a successful tool to reduce curative antibiotic usage.

3. Body defence

The immune system is crucial for both animal health and performance. Animals with a properly working immune system respond adequately to diseases and do not overreact when small challenges occur. Such overreactions can even restrict the animal’s performance to reach genetic growth potential. In vivo trials revealed that alpha-monolaurin improves the immune response of infectious bronchitis vaccinated broilers. In vitro trials confirmed the inflammation inhibiting properties of alpha-monolaurin compared to Oxytetracycline (Figure 1). Oxytetracycline is an antibiotic with strong anti-inflammatory properties.

4. Intestinal health

Its structure enables alpha-monolaurin to remain in active form during the complete passage through the animal’s intestinal tract because it does not dissociate under high pH values. Therefore, alpha-monolaurin is considered pH independent. In addition, alpha-monoglycerides of MCFAs are not susceptible to enzymatic breakdown.

5. User-friendly

Alpha-monolaurin is considered user-friendly because it is easy to handle in the diet of livestock animals. Alpha-monolaurin is non-volatile, non-corrosive, odorless and heat-stable up to 160 degrees Celsius. It already shows promising effects at a low inclusion rate.
