The Victorian Volcanic Plains Grassland: Past, Present And Future, Steve G. Clark, J. Crosthwaite, J. Dorrough, J. R. Hirth, Y. Ingeme, J. Mavromihalis, V. Turner

IGC Proceedings (1997-2023)

The Grasslands of the Victorian Volcanic Plains have been replaced with introduced pastures and crops since European settlement with the loss of many plant and animal species. What remains, on public and private land, has high conservation value and needs urgent protection.

Portuguese Society Of Pastures And Forages, J. Potes, E. V. Lourenço, T. Carita

IGC Proceedings (1997-2023)

The Portuguese Society of Pastures and Forages (SPPF) was born from a course on pastures and forages held in the National Plant Breeding Station of Elvas (where the headquarters of SPPF are located) in 1979. It was organised by the head of the Pastures and Forages Department, David Gomes Crespo, who was the first and founder member. According to Abreu et al. (1999), the structure established was that of a Scientific Society and was considered by the Government as a Service of Public Interest. It gathered inspiration from the British Grassland Society, the Association Francaise pour la Production Fourragére, …

Application Of Molecular Markers In Genetic Resources Management Of Perennial Ryegrass, R. Van Treuren

IGC Proceedings (1997-2023)

Key points

1. Molecular markers are effective tools to support traditional approaches in plant genetic resources management.
2. Genetic diversity assessed for perennial ryegrass by AFLP analysis revealed differentiation of populations occurring in traditional Dutch grasslands from commercial varieties, but not from populations occurring in Dutch nature reserves.
3. No specific conservation measures were recommended to maintain the genetic diversity of perennial ryegrass occurring in traditional Dutch grasslands.
4. Pollination rates estimated by microsatellite analysis for a rejuvenated population of a perennial ryegrass genebank accession were very well described by an inverse quadratic function of inter-plant distance between potential mating pairs, while recorded flowering …

Nutritive Value For Finishing Beef Steers Of Wheat Grain Conserved By Different Techniques, P. Stacey, P. O'Kiely, A. P. Moloney, F. P. O'Mara

IGC Proceedings (1997-2023)

Wheat grain harvested at dry matter (DM) concentrations above 860 g/kg is slow to deteriorate during long-term storage. However, high moisture grain (HMG) ranging from below 600 to 750 g DM/kg is conserved on some farms in the form of anaerobic storage of acid-treated, rolled wheat (AR) and urea-treated whole-wheat (UN) (Stacey et al., 2003). This experiment quantified the nutritive value for beef cattle of standard wheat grain (propionic acid-treated and rolled:PR) compared to AR and UN at different levels of intake.
