Use Of Objective Planning Techniques In The Development Of Large Livestock Farm In New Zealand, K I. Lowe

IGC Proceedings (1977-2023)

Limestone Downs is a sheep and beef cattle property of 3200 ha near Port Waikato, and provides funds for the C Alma Baker Trust for "the furtherance of the science of agriculture". A development programme slatted in 1981 transformed the farm from an extensive "station" into an intensive farming operation, lifting animal performance and financial returns. This followed the adoption of well-proven and relatively inexpensive modifications to management. Similar programmes should have realistic goals, and established decision rules with priorities. These should be supported by an appropriate monitoring programme and the use of objective data in decision making.

Interdisciplinary Research: A Vehicle For Meeting The Information Needs Of Grassland Producers, Robert O. Burton Jr, K P. Coffey, J L. Moyer, L W. Lomas, P T. Berends

Applied Scientific Concepts For Dairy Cows And Crops, J R. Rodgers

IGC Proceedings (1977-2023)

Prom a rural town to a dairy farm, from the halls of ivy to the smooth beauty of contour strips on the land: this paper is a practical application of science and technology transferred, through the life of the author, from the textbook to the bottom line of a financial report at year end. How this transfer of technologies (i.e. alfalfa, manure pits, computers, etc.) was used to develop the workable plan for my dairy farm operation will be addressed in detail in this presentation.

Extension Through The Landcare Movement In Australia's Pastoral Zone, B R. Roberts

IGC Proceedings (1977-2023)

The Landcare movement, presently based on over 1300 landholder committees nationwide, is potentially Australia's most significant popular movement ever. Its success largely depends on producers identifying with the movement and "owning" its objectives and programmes, Central to attainment of Landcare's goals is the support given by technical advisors, These advisors require a special understanding of group extension techniques, group dynamics and the subtleties of invisible leadership when appropriate. In the vast pastoral zone of Australia, where highly independent graziers operate very individualistically, the required group extension is a special challenge to committed advisory officers.

Adopting New Technologies For Grazing Lands: The Role Of Decision Systems, John A. Ludwig, Steve Marsden

IGC Proceedings (1977-2023)

The management of Australia's arid and semi-arid grazing lands involves the consideration of many complex and interconnected issues related to both ecological and economic factors. Climates are highly variable across these lands and markets fluctuate widely; decision making is . difficult at the best of times, As new grazing and land management technologies become available through research organisations, such as CSIRO, the adoption of these technologies is a prime concern, Traditionally, State extension services provide this information to grazing land managers, which has proven effeclive for transferring information about current short-term problems (e,g,, locust plagues) and easy to apply products …

Technology Transfer Strategies For Products Of Environmental Research And Development Projects, N D. Macleod, J A. Taylor, P.G H. Van Beek, P N. Vance

IGC Proceedings (1977-2023)

Potentially high net benefits from Research and Development on sustainable grazing systems will not be captured unless the outcomes are adopted. Adoption is a complex process, often requiring integration with other technologies, and specialised extension packages. Technology transfer strategies based on experiences with relatively simple innovations are unsuited to more complex environmental innovations, A 6-stage interactive process involving researchers, extension specialists and potential end-users is suggested.

Grazier's Pattern Of Understanding Vegetation In The Semi-Arid Rangelands Of New South Wales, S.M M. Kersten, R L. Ison

IGC Proceedings (1977-2023)

A matrix ranking (MR) technique was used by graziers in western New South Wales to rank rangeland plants according to preference. Graziers preferred a variety of plant species in their paddocks: "bushes" and "50f1 feed", perennials and annuals, winter-and summer­growing plants, on both stock-based and non-stock-based criteria, The criteria for evaluation were rarely independent of each other nor of different soil types on the grai:ier's property. Drought resistance was perceived as one of the more important criteria, followed by stock-based criteria such as "nutritious", "palatable" or "quick fattening" stock feed. The utility of MR for allowing graziers' knowledge to be …

Composition Of The Fractions Of Dry, Mature Subterranean Clover Digested In Vivo And In Vitro, L Klein, S K. Baker

IGC Proceedings (1977-2023)

A modified pepsin-cellulase procedure was used to improve the prediction of in vivo digestibility of dry, mature subterranean clovers (Trifolium subterraneum). Feed, faeces, and the residues from this /11 vitro procedure and the i11 vitro procedure of Tilley & Terry were analysed for protein, ash and fibre fractions lo determine the composition of the cell-wall functions that were digested. The extent of digestion of the cell-wall fractions differed between the two in vitro procedures, but the cell-wall fraction that was digested contained similar proportions of cellulose, hemicellulose, protein and lignin. The cellulose and protein contents of the cell-wall digested …

Effect Of Plant Leaf Age On The Production Of Tannins, Phenols, Proanthocyanidins And Flavanols In Eulalia Villosa, M M. Wolfson, E W. Du Toit, P Chesselet

IGC Proceedings (1977-2023)

Histochemical and biochemical analyses have confirmed the presence of condensed tannins in a number of southern African tropical grasses. The ability to precipitate proteins, total phenols, condensed tannin and proanthocyanidin levels were significantly higher in mature leaves of Eulalia villosa than in young leaves. The ratio of condensed tannin to Jlavan 3,4-diols indicated that the young leaf material contained more monomeric unpolymerised flavan 3,4-diol units than mature leaves. The trend is repeated in the ratio 'of proanthocyanidin to flavan-4-ols, These low molecular weight proanthocyanidin precursors probably do not have the ability to precipitate proteins, The histochemical tests can be used …

Effect Of Inoculants And Absorbents Incorporated In Grass Silage On Silage Quality, Effluent Production And Animal Performance, Raymond Jones

IGC Proceedings (1977-2023)

Unwilled ryegrass crops (151 kg DM) were enslled in 70-t bunker silos. Crop analysis (g/kg/DM) was water-soluble carbohydrates 153, nitrogen 24.1 and predicted digestibility (DOMD) 0.67. Molassed sugar beet feed pellets were incorporated at a rate of 25 kg/t in the harvested crop with or without inoculant treatment ("Live Systems", MMB, UK), and compared with a control silage with no additive. Absorbent addition with or without inoculant significantly reduced silage pH and ammonia-N compared with the control. Inoculant treatment further increased lactic acid content. Silage effluent production was reduced by up to 33% by absorbent inclusion with effluent DM losses …

Understanding Point And Slope In Linear Equations And Approximations: A Case Study, Kyunghee Moon

The Mathematics Enthusiast

This article delves into an intervention designed to enhance a precalculus student’s understanding in constructing linear equations and in approximating function values. Before the intervention, the student primarily relied on the algebraic formula y₂-y₁/x₂-x₁ to determine slope, knew slope geometrically as Δ_y/Δ_x solely for integer values, and struggled to construct a linear equation without an explicitly shown y-intercept. Through the intervention, the student comprehended slope m as a unit rate and expanded this understanding to Δy = 𝑚Δ𝑥 for integer Δx by iterating m, Δ𝑥 number of times. She …

Quantinar: A Blockchain Peer-To-Peer Ecosystem For Modern Data Analytics, Raul Bag, Bruno Spilak, Julian Winkel, Wolfgang Karl Hardle

Sim Kee Boon Institute for Financial Economics

The power of data and correct statistical analysis has never been more prevalent. Academics and practitioners require nowadays an accurate application of quantitative methods. Yet many branches are subject to a crisis of integrity, which is shown in an improper use of statistical models, p-hacking, HARKing, or failure to replicate results. We propose the use of a Peer-to-Peer (P2P) ecosystem based on a blockchain network, Quantinar, to support quantitative analytics knowledge paired with code in the form of Quantlets or software snippets. The integration of blockchain technology allows Quantinar to ensure fully transparent and reproducible scientific research.
