Chromium propionate is an essential trace mineral that has been proven safe and effective as an animal feed additive for more than two decades. KemTRACE® Chromium, the chromium propionate product manufactured by Kemin Industries, has helped customers increase production and profitability in the swine, broiler, beef and dairy industries. KemTRACE Chromium, fed to millions of animals around the world since its introduction in 2000, is registered in more than 30 countries.

In a perfect world, feedlot cattle would never be under stress. However, feedlot cattle are presented with daily challenges, which impact their health and performance. Several factors negatively affect animal performance, which causes approximately $1.5 billion in losses per year due to health-related issues.3 One of the most significant factors in animal health and performance is the response to stress. Stress causes the body to redistribute nutrients to maintain and support life. The utilization of glucose by the animal's body is governed by specific hierarchical processes and is dependent on the type of stress the animal is facing.
The body stores chromium in extremely microscopic quantities (parts per billion).4 During times of stress, chromium is rapidly used and released from the body. Research conducted in humans has shown chromium is not stored in the body and is excreted during stress: "Urinary chromium excretion may increase 10-300 times in stressful situations or due to a carbohydrate-rich diet" (Table 1).5
Table 1. Chromium excretion in response to stress factors4,5,6
|STRESS FACTOR||Cr IN URINE (µg/day)|
|Basal State (no stress)||0.16 +/- 0.02|
|Acute Stress||0.30 +/- 0.07 (2X)|
|Diet Rich in Carbohydrates||0.28 +/- 0.01 (2X)|
Research conducted at Ohio State University in feedlot animals demonstrated a positive correlation between days on feed and insulin response. As days on feed increased, the insulin response to the glucose tolerance test increased dramatically. Insulin response to glucose infusion was nearly double on day 111 versus day 21 (Figure 1).7 The longer cattle are on feed, the more insulin resistance increases.
|GLUCOSE||DAY 41||DAY 111||P-VALUE|
|Clearance, mg/min||0.93||1.17||< 0.001|
|Ins: Glc AUC||0.023||0.049||0.0002|
