Animal care

For livestock, our IgY applications focus on supporting the animals’ gastrointestinal health and, thus, enhancing their performance

Thanks to decades of research on maternal immunity mechanism, IRIG has successfully developed many patented IgY applications against different pathogens in human and animals.

Focus areas

IgY for piglets

Diarrhea is the most important disease affecting piglets, causing death and poor performance. As the causative agents of diarrhea consist of various bacteria, viruses, parasites, etc., its control in the farms is very difficult. For more than two decades, we have proven that IgY can be useful in preventing diarrhea and improving piglets’ performance.

IgY for calves

Like piglets, newborn calves frequently suffer from diarrhea and subsequent death due to various infectious agents in the gastrointestinal tract. These include bacteria, viruses, and protozoa. More than 20 years ago our institute was the first to demonstrate that IgY specifically prepared against E. coli and rotaviruses could be used to control these infections in newborn calves.
Our research has shown that specific combinations of different IgY can help the animals grow better.
