Ryegrass Staggers: Management and Control
An outline is given of some of the main factors and interactions involved in the development of ryegrass staggers viz: pasture structure, neurotoxin distribution within the pasture, and livestock feeding behaviour. Because neurotoxicity is mainly associated with ryegrass leaf sheath the aim of control measures is to minimise ingestion of this component when it is toxic. This can best be achieve...
متن کاملRyegrass Staggers: Clinical, Pathological and Aetiological Aspects
This paper briefly introduces animal disease aspects of ryegrass staggers IFiGS) and describes the occurence and the clinical signs of the disease. Recent suggestions for the production of a reversible biochemical lesion in the central nervous system are mentioned in relation to the apparent lack of specific morphological lesions found in sheep. The recent isolation of novel potent neurotoxins,...
متن کاملRyegrass in pastures – breeding for resilience
The suggestion that modern pasture cultivars persist less well than their predecessors is not supported by facts. However in some regions there is a crisis in farmer experience of persistence of ryegrass pastures, and ryegrass breeding can contribute to a resolution. This paper considers the turnover of tillers in a pasture, the population structure of a grass sward and the involvement of endop...
متن کاملRyegrass Swards Compared with Perennial Ryegrass Swards on the Performance and Carcass Quality of Grazing Beef
An experiment investigated whether the inclusion of chicory (Cichorium intybus) in swards grazed by beef steers altered their performance, carcass characteristics or parasitism when compared to steers grazing perennial ryegrass (Lolium perenne). Triplicate 2-ha plots were established with a chicory/ryegrass mix or ryegrass control. Forty-eight Belgian Bluecross steers were used in the first gra...
