Cultivar Effects of Perennial Ryegrass on Herbage Intake by Grazing Dairy Cows
Perennial ryegrass is the most abundant grass species in temperate climates. An increased herbage intake of dairy cows by breeding new cultivars could have a large potential impact on agriculture. The effects of cultivars on sward structure, nutritive value, physical characteristics and disease resistance of perennial ryegrass are discussed. Cultivar differences were found in several studies fo...
متن کاملSimulating perennial ryegrass cutting
Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...

متن کاملGrowth Characteristics of Perennial Ryegrass
Mature perennial ryegrass plants in pastures persist through the asexual reproduction of the tiller. Leaves are initiated from the flanks of the tiller stem apex. Generally, two leaves arc growing on a tiller at any one time. New tiller buds may arise from the axils of mature leaves depending on environmental conditions. Flowering results from a physiological change at the stem apex, which then...
متن کاملEffect of pre-grazing herbage mass on dairy cow performance, grass dry matter production and output from perennial ryegrass (Lolium perenne L.) pastures.
A grazing study was undertaken to examine the effect of maintaining three levels of pre-grazing herbage mass (HM) on dairy cow performance, grass dry matter (DM) production and output from perennial ryegrass (Lolium perenne L.) pastures. Cows were randomly assigned to one of three pre-grazing HM treatments: 1150 - Low HM (L), 1400 - Medium HM (M) or 2000 kg DM/ha - High HM (H). Herbage accumula...
