Research Studies Demonstrate Benefits of Supporting Dairy Cattle Immune Function


Research Studies Presented at 2013 American Dairy Science Association Meeting Demonstrate Benefits of Supporting Dairy Cattle Immune Function

PRINCEA healthy immune system is vital to help maintain overall dairy cow health and improve milk production. Research presented at the 2013 American Dairy Science Association – American Society of Animal Science Joint Annual Meeting demonstrated the positive impact of the nutritional supplement OmniGen-AF® from Prince Agri Products, Inc. in helping to support the cow’s natural immune system against multiple sources of year-round stress.

Multiple abstracts were presented at the meeting, summarizing new university and field research studies:

  • “Evaluation of OmniGen-AF® in heat‐stressed Holstein cows in lactation (Abstract 458).” Research conducted at the University of Arizona, using cows housed in environmentally-controlled modules, indicated animals receiving OmniGen-AF had significantly greater dry matter intake, less water consumption, reduced respiration rates and lower rectal temperatures during heat stress than control cows.
  • “Milk and milk quality evaluated on a commercial Holstein dairy following an OmniGen-AF® dry cow and early lactation feeding strategy (Abstract T33).” This trial, conducted at an 8,000-cow farm, showed mature Holsteins fed OmniGen-AF from dry-off through 30 days in milk had statistically higher first test day, 4-week and peak milk yields than cows that did not receive the product.
  • “Growth and health costs used to evaluate OmniGen-AF® feeding strategies in Jersey heifer calves reared on a commercial dairy (Abstract T156).” Jersey calves receiving supplemental OmniGen-AF from one to 50 or one to 160 days of age had improved growth and health, with reduced medication costs, compared to calves not receiving the product.
  • “OmniGen-AF® supplementation improves leukocyte responses and hematology of multiparous peripartum cows (Abstract T162).” Researchers at Texas Tech University found neutrophils (white blood cells that provide early protection against infections) obtained at calving from cows fed OmniGen-AF beginning at dry-off, compared to cells from cows not receiving the product, had higher L-selectin content, but lower oxidative burst intensity in response to E. coli. Cows receiving OmniGen-AF also had lower plasma haptoglobin concentration at 14 days after calving, versus controls. These results suggest feeding OmniGen-AF helped improve health status of cows during the transition period.

OmniGen-AF, a unique patented product from Prince Agri Products, can be supplemented to all classes of dairy cattle as part of their regular diet.
