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.

 

Milk Response

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.

Effect of chromium supplementation in lactating dairy cow diets on response to daily milk yield

Chromium Sensitivity Analysis

A statistical weighted average of the refereed journal publications shown in Figure 1 was calculated. The weighted average response in daily milk yield calculated out at 1.56 ltr/head/day. Table 1 shows a sensitivity analysis based on differing milk prices ranging from $64.10/hectoliter (hl) to $71.30/hl assuming cows achieve anywhere from 20% to 100% of the weighted average milk response.

Feeding KemTRACE® Chromium 0.4% in a High-Producing, Robotically-Milked Jersey Herd in Ontario, Canada

 

Chromium is considered an essential nutrient that improves insulin sensitivity. Supplementing chromium to dairy cows has been shown to increase milk yield and enhance reproductive performance. Recently, chromium propionate has been approved for use as a chromium supplement in diets for dairy cattle in the U.S. and Canada, and it is important to evaluate the effect of chromium propionate supplementation when fed to high-producing Jersey cows.
