Breeding Morphogenetic Traits To Match Genotypes To Their Utilization, L Hazard, M Betin, M Ghesquiere Mar 2024

Breeding Morphogenetic Traits To Match Genotypes To Their Utilization, L Hazard, M Betin, M Ghesquiere

IGC Proceedings (1997-2023)

A divergent selection for lamina length was done from natural populations of perennial ryegrass. Tested in a multi-site experiment in France, the short-leaved perennial ryegrass was more productive under simulated grazing and less productive under infrequent cutting than the long-leaved perennial ryegrass. Matching cultivars to their management is possible by selecting for morphogenetic traits. However, our results suggest the range of adaptation to different managements of perennial ryegrass cultivars could be extended by increasing their phenotypic plasticity.

Evaluation Of Oat Genotypes For Forage And Seed Production In The Northeast Region Of Sao Paulo State-Brazil, R A. Reis, L R. De A. Rodrigues, T De J D. Rodrigues

IGC Proceedings (1997-2023)

The DM production (DMP), chemical composition, and seed production of black oats (Avena strigosa Schreb.) and the yellow oat cultivars ‘UPF2’ , ‘UPF3’ and ‘UPF7’ (A. byzantina C. Kock.) were evaluated under two management systems: plants cut (60 days after sowing-DAS) and uncut for seed production. Oat genotypes were sown in 1993 and 1994. UPF7 was the least productive. No difference was detected (P > 0.05) in the cell wall composition of the genotypes. High values of CP (22.9%) and IVDMD (77.6%) were determined across all genotypes. In 1994, cutting at 60 DAS affected the seed production of the cultivars. …


Contribute To A Definition Of Extensive Grazing (Mediterranean), J. Potes, J. P. F. Almeida, C. Matos, A. Teixeira Feb 2024

Contribute To A Definition Of Extensive Grazing (Mediterranean), J. Potes, J. P. F. Almeida, C. Matos, A. Teixeira

IGC Proceedings (1997-2023)

The subject of this paper is a definition of Extensive Grazing from Extensive Systems of Animal Production in Mediterranean environments. The edaphoclimatic characterization is essential to understand the low level of primary productivity as a consequence of irregular precipitation over the year and its absence during the long, dry and hot summer. The powerless of soils justify the limited contribution of plants and make clear the necessary recovery of the soil and storage of water naturally (soil) or artificially (irrigation). Considering the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) definition of extensive grazing it has been used the …

Integrating Plant Secondary Metabolites And Foraging Behavior To Enhance Animal Health In Ruminant Production Systems, J. J. Villalba, J. W. Macadam, S. Van Vliet, F. D. Provenza Feb 2024

Integrating Plant Secondary Metabolites And Foraging Behavior To Enhance Animal Health In Ruminant Production Systems, J. J. Villalba, J. W. Macadam, S. Van Vliet, F. D. Provenza

IGC Proceedings (1997-2023)

Legumes and forbs contain bioactives or plant secondary compounds (PSC) with potential to enhance animal health through their antibiotic, antioxidant and immunomodulatory properties that are evident even at small dietary concentrations. In turn, ruminants can regulate their ingestion of PSC through behavioral mechanisms that allow for the efficient achievement of homeostasis. High concentrations of PSC lead to food avoidance, whereas lower content of PSC in the diet achieved through regulatory mechanisms of ingestion could promote medicinal and/or prophylactic effects in the animal and concomitant health benefits to milk and meat products. Under this context, we discuss the restructuring of rangelands …


The Future Of Clovers In Forage Systems And As Cover Crops, J. H. Bouton, John R. Caradus Jan 2024

The Future Of Clovers In Forage Systems And As Cover Crops, J. H. Bouton, John R. Caradus

IGC Proceedings (1997-2023)

Clovers (Trifolium spp.) are the most widely used genera of legumes in forage systems, although only a limited number of the hundreds of perennial and annual species are commercially available. The number of varieties available within each of the main commercial species can be high and demonstrates past breeding achievements. Success relates to any clover’s ability to persist in mixtures with other forage species, across a range of soil types, management systems, and climates, while providing animal nutrition and biologically fixed nitrogen benefits. Uses range from traditional pasture mixtures with grasses to inclusion in multi-species mixtures, and as cover …

Comparing Forage Biomass Estimation Between Forager-Mounted Near Infrared Spectroscopy (Nirs) And Rising Plate-Meter (Rpm) Techniques, Andy G. Jones, G. Irisarri, T. Takahashi, M. J. Rivero, P. Harris

IGC Proceedings (1997-2023)

Quantifying the forage mass harvested per paddock is essential for informing late-season management decisions on grazing livestock farms. This information can be used to calculate winter feed budgets and thus support decisions such as area of land to defer for autumn grazing, and head of stock to sell before winter housing. However, there are practical limitations associated with existing measurement methods, which can influence the accuracy of forage biomass estimates. The purpose of the current study was therefore to compare biomass estimation from two alternative precision farming methods — near infrared spectroscopy (NIRS) integrated within-spout of a self-propelled forage harvester, …


Conservation Reserve Program Hay Quality From Producer Submissions To A Commercial Laboratory In Central Nebraska, R. J. Kern-Lunbery Jan 2024

Conservation Reserve Program Hay Quality From Producer Submissions To A Commercial Laboratory In Central Nebraska, R. J. Kern-Lunbery

IGC Proceedings (1997-2023)

The Conservation Reserve Program (CRP) sets aside hectares to be permanent grassland and keeps those acres out of rotation for agricultural use. In drought conditions, these acres open to emergency haying and grazing. CRP hay is harvested at the end of the primary nesting season, mid to late summer, therefore this is a very mature product for stored forage. Many beef cow producers in the Midwest feed CRP hay in the last third of gestation until cattle can be turned out for spring grazing. Data was obtained from CRP hay samples to evaluate forage nutritive value and supplementation needs relative …

School of Natural Resources: Faculty Publications

Background: Large-river decision-makers are charged with maintaining diverse ecosystem services through unprecedented social-ecological transformations as climate change and other global stressors intensify. The interconnected, dendritic habitats of rivers, which often demarcate jurisdictional boundaries, generate complex management challenges. Here, we explore how the Resist–Accept–Direct (RAD) framework may enhance large-river management by promoting coordinated and deliberate responses to social-ecological trajectories of change. The RAD framework identifies the full decision space of potential management approaches, wherein managers may resist change to maintain historical conditions, accept change toward different conditions, or direct change to a specified future with novel conditions. In the Upper Mississippi …

USDA Wildlife Services: Staff Publications

Having entered into its second century, the eradication program for bovine tuberculosis (bTB, caused by Mycobacterium bovis) in the United States of America occupies a position both enviable and daunting. Excepting four counties in Michigan comprising only 6109 km2 (0.06% of US land area) classified as Modified Accredited, as of April 2022 the entire country was considered Accredited Free of bTB by the US Department of Agriculture for cattle and bison. On the surface, the now well-described circumstances of endemic bTB in Michigan, where white-tailed deer (Odocoileus virginianus) serve as a free-ranging wildlife maintenance host, may appear to be …


Is Biodiversity Declining In The Traditional Haymeadows Of Skye And Lochalsh, Scotland?, G. E. D. Tiley, D. G. L. Jones Aug 2023

Is Biodiversity Declining In The Traditional Haymeadows Of Skye And Lochalsh, Scotland?, G. E. D. Tiley, D. G. L. Jones

IGC Proceedings (1997-2023)

Species-rich haymeadows have developed on crofts in the Isle of Skye and Lochalsh Districts of north-west Scotland as a result of a century or more of traditional land use. This has involved long rotations of late cutting for hay with aftermath grazing by cattle and short breaks for cropping. The traditional haymeadows are increasingly coming under threat from changes taking place in the countryside. A survey of the main haymeadows still remaining in Skye and Lochalsh was carried out during 2003 to assess the current botanical composition, management and conservation value, and to compare with earlier surveys.

Modelling The Effect Of Breakeven Date In Spring Rotation Planner On Production And Profit Of A Pasture-Based Dairy System, P. C. Beukes, B. S. Thorrold, M. E. Wastney, C. C. Palliser, G. Levy, X. Chardon

IGC Proceedings (1997-2023)

The breakeven date is the expected date when pasture supply exceeds cow demand. This date is used to plan the rotation rates, slow during the winter, when pasture growth is low and cows are dry, to a fast rotation in spring, when growth is accelerating and most cows lactating. This date is influenced by regional climate, mainly rainfall and soil temperature, which affects timing and rate of growth acceleration. The objective of this modeling exercise was to explore the effect of the breakeven date on milksolids (MS), grass silage, farm cover and economic farm surplus (EFS) over different climate years …


Grasscheck: Monitoring And Predicting Grass Production In Northern Ireland, P. D. Barrett, A. S. Laidlaw Aug 2023

Grasscheck: Monitoring And Predicting Grass Production In Northern Ireland, P. D. Barrett, A. S. Laidlaw

IGC Proceedings (1997-2023)

Grass budgeting is a key management practice on dairy farms to balance grass supply on paddocks with grass demand by the grazing herd. Grass budgets must be pre-emptive to be effective. The uncertainty of grass production and the difficulty in quantifying both current and forecasted rates of growth hamper effective budgeting and paddock management. Grass growth rates are highly variable both in time and space. Therefore, they vary greatly between locations at any given time and also across the season at any given location. Figure 1 shows the pattern of growth rates recorded at the Agricultural Research Institute of Northern …

On-Farm Information: A Valuable Tool For The Sustainable Management Of Mountain Pastures In Protected Natural Areas, N. Mandaluniz, A. Bernués, A. Igarzabal, I. J. L. Riedel, R. Ruiz, A. Sanz, I. Casasús, L. M. Oregui

IGC Proceedings (1997-2023)

Mountain pastures have traditionally been maintained by livestock. The analysis of data concerning farms' characteristics, productive-reproductive management and land use of commercial farms can constitute a real approach to study these systems and the changes that are occurring. This information is necessary to develop new utilisation guidelines, making compatible livestock production and conservation of natural resources. This paper describes a methodological framework to study the issues described above through some examples taken out from a wider research project (Mandaluniz et al., 2003).


Disappearance Of Residual Dry Matter On Annual Grassland In The Absence Of Grazing, W. E. Frost, J. W. Bartolome, K. R. Churches Aug 2023

Disappearance Of Residual Dry Matter On Annual Grassland In The Absence Of Grazing, W. E. Frost, J. W. Bartolome, K. R. Churches

IGC Proceedings (1997-2023)

Residual dry matter (RDM) is a standard used by grassland managers for assessing the level of grazing use on annual grasslands and associated savannas and woodlands. Residual dry matter is the old plant material left standing or on the ground at the beginning of a new growing season. It indicates the combined effects of the previous season's forage production and its consumption by grazing animals of all types. The standard assumes that the amount of RDM remaining in the fall, subject to site conditions and variations in weather, will influence subsequent species composition and forage production, in addition to providing …

Institutions, Structures And Topics Of Grassland Research In Germany - From Science To Practice, Johannes Isselstein, H. Hochberg

IGC Proceedings (1997-2023)

In Germany, grassland covers some 30% of the agriculturally used land. It forms the basis of forage production in dairy and beef cattle husbandry as well as sheep and horse feeding. The intensification of grassland farming during the last fifty years was made possible through extended basic and applied research in all fields of grassland management. This included the improvement of forage species and varieties by plant breeding, the adaptation of botanical knowledge for the control of the botanical composition of permanent grass swards, the application of regular fertilisation, the improvement of the grazing management, the increased frequency of utilisation …


The Flow Of Power: Addressing Asymmetric Flood Risk In The Upper Valley, Eric Vr Hryniewicz Jun 2023

The Flow Of Power: Addressing Asymmetric Flood Risk In The Upper Valley, Eric Vr Hryniewicz

Geography Undergraduate Senior Theses

Floods are the most damaging natural disasters in America. Land use change in upland watersheds can increase the probability and severity of floods (Bronstert, Niehoff, & Burger, 2002). When watersheds are divided by political and private property boundaries it leads to a misalignment of incentives in which downstream users lack recourse for upstream land use decisions contributing to flood risk. In this thesis, researchers interrogate the attributes of town officials and towns that determine what motivates town governments to act on flooding and what motivates and enables town officials to collaborate on planning and how do they collaborate in practice. …

Sustainability Analysis: Large-Scale Desalination Implications For Coastal California, Elizabeth H. Whitford May 2023

Sustainability Analysis: Large-Scale Desalination Implications For Coastal California, Elizabeth H. Whitford

Master's Projects and Capstones

In response to prolonged drought, desalination is gaining popularity as an alternative water production method for fresh water. However, water desalting technology poses concerns; the process is energy intensive, creates brine waste, and has the potential to damage sensitive coastal ecosystems. Significant research is available on the technological, economic, and energy efficiency aspects of desalination, while only a small percentage of the current literature focuses on environmental impacts. This research analyzes the desalination literature holistically in terms of both energy consumption and environmental impacts by conducting 1) a historical and current state review of the sector, 2) a technology analysis …
