Milk Response
The research with chromium in dairy cattle since the turn of the century has shown chromium supplementation is beneficial for improving milk yield in transition cows, maintaining milk yield in heat stressed cows and enhancing reproductive performance in dairy cows. The calculation of the weighted average milk response from all the chromium research between 2000 and 2015, and the sensitivity analysis at differing milk prices, allows producers to understand the impact chromium can have on herd profitability.
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. Optimized glucose utilization can result in better animal maintenance, production, immunity, growth and reproduction.
Review of the Milk Yield Response to Chromium Supplementation in Lactating Cows
Figure 1 demonstrates the effects of supplementing chromium on milk production. Seventeen published articles between 2000 and 2015 from refereed journals focusing on dairy cows were used to generate the figure. The graph depicts the milk yield response to chromium supplementation within a university-controlled study in comparison to the control (i.e. non-chromium supplemented cows). This summary includes different chromium sources fed at different levels and is not limited to KemTRACE® Chromium.

Chromium and Milk Response Literature
KemTRACE® Chromium for Dairy: Milk Response
The research with chromium in dairy cattle since the turn of the century has shown chromium supplementation is beneficial for improving milk yield in transition cows, maintaining milk yield in heat-stressed cows and enhancing reproductive performance in dairy cows.
The Effect of Chromium Propionate on Lactating Jersey Cows in Early to Peak Lactation
A field trial was conducted at a dairy in the Central Valley region of California. Approximately 500 cows in second or greater lactation in the high producing group (60-120 DIM) were used. The objective was to determine if chromium propionate had a benefit to dairy cows in early to peak lactation.
Effects of Chromium Propionate Fed Through the Periparturient Period and Starch Source Fed Postpartum on Productive Performance and Dry Matter Intake of Holstein Cows
Forty-eight Holsteins entering second or greater lactation were used to determine milk production, DMI and metabolic responses to chromium propionate supplementation through the periparturient period and starch source in postpartum.
