The IMM Index is a robust index with CBCD, Lactanet, Zoetis¹, Semex data and the bull’s own response to bacteria and viruses.

The IMM Index enables broad selection for overall reduction of most bacterial, viral, and mycobacterial diseases.

Immunity+ bulls’ daughters have 30% less overall disease compared to herdmates:

• 30% less Mastitis
• 31% less Lameness
• 25% less Retained Placenta
• 42% less Ketosis
• 15% less Displaced Abomasum
• 6% less Metritis
• 24% less treatment necessity for Bird Flu

The easiest way to select for permanent herd health is using the Immunity Index.

Elevate genomic test gives you all the data you need to know which calves, heifers, and cows are the healthiest with an Immunity+ index ranking.

Females that are High Immunity (≥ 105) have 30% less overall disease than herdmates.

Knowing genomic immune response equals better management and breeding strategies for both herd health and genetic merit.

Healthier calves grow better and are the foundation of a healthy, fertile and profitable herd.

High Calf IM bulls’ (≥ 105) daughters have less disease than herdmates:

• 32% less overall calf disease
• 33% less Pneumonia
• 31% less Diarrhea

Colostrum is the number one most important factor in keeping calves alive.

Calves are born with no immunity, and most will not survive without quality colostrum.

High Immunity females are proven to produce higher quality colostrum with more antibodies, total immunoglobulin, and beta lactoglobulin.

Colostrum from high Immunity cows leads to better calf development and growth.

Calves that respond better to vaccines have lower disease risk, grow better, eat more and are stronger, more productive cows.

96% of high Immunity females have a positive, high response to vaccines compared to 80% of population.

Healthy cows have fewer days open, higher conception rates and more lifetime productivity.

High Immune females are healthier:

• Less disease
• Stronger hormone functions
• Healthier uterus
• Undergo less stress

High-heritability means faster genetic progress.

Fertility and health traits are generally low heritability.

Immunity is 30% heritable.

Immunity+ accumulates with each generation like milk, fat and other high-heritability traits.
