Silage and Haylage — Perennial Ryegrass

Lolium perenne L.

Perennial ryegrass is characterized by high digestibility and significant sugar content, which allows it to ensile well. The efficiency of harvesting depends on the morphological characteristics of the varieties and strict adherence to mowing schedules to balance nutritional value.

In the reference 129 varieties crop Perennial ryegrass, where this is mentioned in the description.

Perennial ryegrass possesses high organic matter digestibility, which can reach 70–78% at early heading stages. Due to the significant content of water-soluble carbohydrates, the crop is capable of fermenting without the addition of preservatives; however, if compaction technology or moisture levels are not managed correctly, there is a risk of Clostridia development.

Variety selection influences harvesting technology: diploid varieties are distinguished by a higher dry matter content, whereas tetraploid varieties contain more sugars but require monitoring due to higher mass moisture. The optimal harvesting period is between 5 and 7 weeks; later dates lead to a decrease in sugar concentration and overall feed digestibility.
