Introducing Perennials Into Grasslands In South West Australia Increases Gross Margins For Dual Purpose Merino Enterprises, Paul Sanford
Introducing Perennials Into Grasslands In South West Australia Increases Gross Margins For Dual Purpose Merino Enterprises, Paul Sanford
IGC Proceedings (1997-2023)
Dual purpose Merino enterprises on the south coast of Western Australia (WA) typically utilise agricultural grasslands that comprise entirely of annual plant species. These grasslands face a range of challenges including a variable Mediterranean climate coupled with mostly infertile fragile sandy soils. As a consequence livestock producers have to manage potentially high supple-mentary feeding costs particularly in summer and autumn while running sufficient livestock to remain profitable. Sowing summer-active perennial species into these grasslands has been shown through short-term livestock trials to allow an increase in stocking rates and reduce the amount of supplement fed. The objective of this investigation …
Plantain (Plantago Lanceolata) In Herb And Legume Pastures Increases Lamb Growth Relative To Perennial Ryegrass And White Clover Pasture, Peter D. Kemp, Paul R. Kenyon, Stephen T. Morris, Sharini C. Somasiri
Plantain (Plantago Lanceolata) In Herb And Legume Pastures Increases Lamb Growth Relative To Perennial Ryegrass And White Clover Pasture, Peter D. Kemp, Paul R. Kenyon, Stephen T. Morris, Sharini C. Somasiri
IGC Proceedings (1997-2023)
Increased use of plantain (Plantago lanceolata) by New Zealand farmers has created a demand for a more complete understanding of the performance and manage-ment of plantain by itself and in various combinations with chicory (Cichorium intybus) and legumes such as white clover (Trifolium repens) and red clover (T. pratense). The objective of this study was to evaluate lamb finishing on plantain by itself and combined with chicory, white and red clover as part of a research programme to develop a temperate perennial pasture superior in animal performance to perennial ryegrass and white …

Effects Of Two Intake Levels Of Leucaena Leucocephala On Rumen Function Of Sheep, Marcos Barros-Rodríguez, Javier Solorio-Sánchez, Carlos Sandoval-Castro, Athol V. Klieve, Eduardo Briceño-Poot, Luis Ramírez-Avilés, Rafael Rojas-Herrera
IGC Proceedings (1997-2023)
Ruminant production systems based on grass pastures often produce poor animal performance as expressed by growth or reproductive rates. The nutrient imbalance affecting rumen function is due to their low energy and protein intake. The incorporation of leguminous forages such as Leucaena leucocephala, in the diet of ruminants, can stimulate rumen function by providing protein-rich forage (Barros-Rodriguez et al. 2012). This increases the availability of compounds such as ammonia, amino acids and peptides as well as branched short-chain fatty acids, which are produced as a result of degradation of proteins. These substances promote fibre breakdown by acting as ruminal …

Characterizing Foraging Patterns Among Cattle And Bonded And Non-Bonded Small Ruminants Using Spatial Point Process Techniques, D. M. Anderson, L. W. Murray, P. Sun, E. L. Fredrickson, R. E. Estell, V. B. Nakamatsu
Conference on Applied Statistics in Agriculture
This paper uses the technique of spatial point processes to describe the spatial patterns of freeranging cattle and small ruminants. Two mixed-species livestock groups were monitored while foraging on 410 ha of brush-infested Southern New Mexico rangeland during July and August 1988. The groups consisted of crossbred Bos taurus and Bos indicus beef cattle with white-faced sheep (Ovis aries) and mohair goats (Capra hircus). The bonded group consisted of small ruminants that had their behaviours modified through socialization with cattle to form a ‘flerd’ in which small ruminants consistently remained near cattle. Small ruminants in the non-bonded group had not …
