Questions About OmniGen?

What is unique about the OmniGen family of nutritional specialty products?
Whether they choose to feed OmniGen Pro, OmniGen AF, OmniGen Green or OmniGen WYC, dairy producers can count on the OmniGen family of nutritional specialty products to help their dairy cows maintain a healthy immune system. A healthy immune system can lead to improved health during all phases of lactation.
What is the impact of heat stress on dairy cows and the dairy industry?
Heat stress costs the U.S. dairy industry $1.5 billion annually. When temperatures and humidity interact to create a Temperature Humidity Index of 68, dairy cows can experience heat stress, leading to lower milk production, increased metabolic disorders, reduced reproductive performance and impaired immune function. OmniGen nutritional specialty products help producers stay a step ahead of heat stress by supporting a healthy immune system. Cows with improved immune function can improve producers’ bottom lines as well as cow comfort and health.
How can producers be confident in the quality of OmniGen ingredients?
All OmniGen nutritional specialty products are backed by Phibro’s Dynamic Quality Assurance® (DQA®) program, meaning they’ve undergone a stringent and rigorous testing program.
Which OmniGen product is right for an organic dairy?
OmniGen Green is a nutritional specialty product that was designed to help organic dairy producers optimize profitability and organic milk quality.

What research is available to support the performance of the OmniGen family of products?
The OmniGen Research Index is a collection of over 110 published university research and field studies. The research shows that continual feeding of OmniGen helps support a healthy immune system, which may lead to fewer health events, lower somatic cell counts and fewer cases of mastitis and metritis. With healthy immune function, dairy cattle are better prepared for stressors, reducing the need for antibiotics and other costly treatments, helping cows achieve their full potential while optimizing production costs and overhead. This research is available in Research Index Volume 4, which can be found in the resources section of the website here.
What are the primary benefits of a healthy immune system in dairy cattle?
Increased milk production, better health and improved reproductive performance are among the primary benefits of feeding OmniGen. A recent study by the University of Florida showed a 2.5:1* return on investment (ROI) when feeding OmniGen nutritional specialty product. This study included an economic analysis and was presented at the American Dairy Science Association Annual Meeting in June 2020. This study showed a benefit of $79 per cow minus a feed cost of $32, which resulted in an estimated 2.5:1* ROI, due to increased milk production, better health and improved reproductive performance.
