Are Your Birds Reaching Their Full Genetic Potential?

Chromium supplementation has been shown to interrupt the biological stress cycle by minimizing the negative effects of stressors — like disease and temperature fluctuations.

Mode of Action

When a bird is exposed to environmental or disease stressors, a stress hormone called corticosterone is released. The release of corticosterone alters how nutrients are utilized by the bird. During periods of stress, nutrients are re-allocated from growth toward minimizing the stress being experienced by the bird. When nutrients are siphoned away from growth in this way, performance can be negatively impacted. 

Chromium supplementation has been shown to decrease the levels of corticosterone in the blood, thereby alleviating the negative effects of stress on growth and performance to allow the bird to reach its full genetic potential.1-4

Four separate university studies utilizing different genetic strains of birds, ages, body weights and environmental stressors (e.g. heat stress, vaccinations, etc.) demonstrated that the addition of chromium propionate in feed resulted in consistent improvements in adjusted feed conversion ratio (FCR), mortality and breast meat yield (Table 1). These university results coincide with the results seen in field evaluations with chromium propionate supplementation.

The results of both university and field evaluations demonstrate that KemTRACE Chromium is a highly bioavailable source of chromium that minimizes the impacts of stress, thus improving both performance and processing parameters.5
