KemTRACE® Chromium and Immunity

 

KemTRACE® Chromium is a highly bioavailable, organic source of chromium that helps stabilize insulin receptors in cattle. This improves glucose utilization for increased energy and proper cell function, resulting in better immunity.

Animals Experiencing Frequent Immune Challenges May Have:

  • Decreased growth
  • Inefficient feed utilization
  • Poor reproduction
  • Increased health costs

How Often Does an Immunity Challenge Occur?

Dairy cows are constantly at risk of being challenged by Escherichia coli  mastitis, Salmonella  infections, mycotoxin insults and more. The impact of even a minor immune challenge could be significant, especially if lipopolysaccharides (LPS) are reduced. In fact, 1/10 less of the LPS could result in 2.78 kg of milk loss per day.1 At $70 per hectoliter, that's $1.95 lost per cow per day.

 

In order to combat an immune challenge, an active immune system requires 4 lbs. of sugar over a 24-hour period. The sugar meant for milk production will instead be used to support this immune function, reducing total milk production and profitability.

Impact of Chromium on Immunity

Research studies have reported improved immune function of activated leukocytes when animals were supplemented with chromium.2,3,4

A recent study conducted with lactating Holstein cows observed the following:

INCREASED CIRCULATING NEUTROPHIL COUNTS IN LIPOPOLYSACCHARIDE (LPS) - administered cows supplemented with chromium (Figure 1).5

Fending Off Infection

Research at Cornell University suggests that:

SUPPLEMENTAL CHROMIUM ENHANCED IMMUNE RESPONSES in early lactation to bacterial challenges in the uterus by increasing neutrophil proliferation (Table 1).6

Increased neutrophil proliferation more effectively cleared infections, which resulted in fewer cows with subclinical endometritis – a leading cause of reduced first service insemination conception rates. Ultimately, improving overall herd reproductive health should contribute to lower veterinary/medical costs, lower improved conception rates, and more optimal milk production.
