KWS evaluates corn silage with nutrition experts

KWS selects new corn silage varieties using evaluations that include partnerships with animal nutrition specialists and trials conducted by Arvalis. This approach ensures that the chosen varieties not only yield well but also provide high nutritional value for dairy cows.

Nutritional value impacts dairy farm profitability

The choice of corn silage variety should not focus only on yield, as the profitability of a dairy farm also depends on the nutritional value of the forage. Factors such as starch content, fiber digestibility, and milk yield are crucial in determining overall performance.

KWS uses MCA to measure performance

To evaluate the overall performance of corn silage varieties, KWS highlights the Margin on Feed Cost (MCA). This indicator combines yield and nutritional quality, providing a comprehensive measure of the variety's impact on farm profitability.

EnergyBOOST label identifies high-performing varieties

KWS has developed the EnergyBOOST label to distinguish corn silage varieties with high energy density. These varieties are designed to improve milk production and the profitability of dairy farms by offering better nutritional benefits.

Trials confirm EnergyBOOST effectiveness

Nine varieties are currently labeled under the EnergyBOOST label, and trials conducted by Arvalis have validated their effectiveness. An independent trial at the experimental farm of La Jaillière showed that using a KWS variety increased milk production and improved the margin on feed cost.

KWS trial results show significant improvements

In a twelve-week trial, cows fed with the KWS variety produced an additional 1 kg of raw milk per cow per day. This resulted in a 16-cent improvement in the margin on feed cost per cow per day. For a herd of 120 cows, this translates to about 43,800 liters of milk and an additional 7,000 euros of margin per year.

Experts highlight importance of forage quality

Fabrice Bedel, ruminant manager at Mixsciences, notes that the Arvalis trial for KWS is innovative. It directly links the performance of corn in the field to its impact on milk production. He emphasizes that high starch content and good fiber digestibility contribute to better milk output and animal health.

MCA is key to measuring livestock profitability

Bedel also points out that the Margin on Feed Cost (MCA) is an essential but rarely used indicator by seed companies. He argues that the better the forage quality, the greater the technical and economic performance of the farmer.
