This My Forage System video explains best practices for producing high quality corn silage.

Here are the key points to remember:

Factors affecting silage quality:

  • Plant maturity: Dry matter is a key indicator of maturity. It is recommended to harvest maize when the dry matter is between 32 and 35%.

  • Cutting length: The cutting length should be adjusted according to the dry matter content. For silage with 32-35% dry matter, a 3/4 inch cut length is recommended.

  • Whether or not to use screening rollers: Screen rollers can help break up corn kernels, making it easier for cows to digest them. They are especially useful for maize harvested before it reaches optimum maturity.

  • Cutting height: Increasing the cutting height can increase dry matter yield, but it can also reduce silage quality. It is important to weigh the pros and cons before choosing a cutting height.

  • Silo compaction: Proper silo compaction is essential to prevent mold and bacteria from growing.

  • Storage: Silage must be covered with plastic to prevent the entry of air and water.

Impact of dry matter on silage quality:

  • Silage with too high dry matter content (over 40%) can lead to a decrease in milk production and health problems in cows.

  • Silage with too low dry matter content (less than 28%) can lead to acetic fermentation and loss of nutrients.

Recommendations for an optimal harvest:

  • Harvest maize when the dry matter is between 32 and 35%.

  • Adjust the cutting length according to the dry matter content.

  • Use screening rolls for maize harvested before it reaches optimum maturity.

  • Compact the silo properly.

  • Cover the silo with plastic to prevent air and water from entering.

Conclusion:

By following these best practices, producers can produce high-quality corn silage that will feed their cows and improve their milk production.
