Lucerne Crown And Taproot Biomass Affected Early-Spring Canopy Expansion, E. I. Teixeira, D. J. Moot, A. L. Fletcher Feb 2023

Lucerne Crown And Taproot Biomass Affected Early-Spring Canopy Expansion, E. I. Teixeira, D. J. Moot, A. L. Fletcher

IGC Proceedings (1977-2023)

Leaf area index (LAI) quantifies canopy expansion in crops and is used in lucerne (Medicago sativa L.) simulation models to predict daily PAR interception (PAR i). This then drives yield through radiation use efficiency (RUE) (Gosse et al., 1984). In perennial crops, like lucerne, the level of biomass stored in crown and taproot may affect canopy expansion in subsequent regrowth cycles (Avice et al., 1997). In temperate regions the impact of this is likely to be greatest in early-spring, when low temperatures delay development. The objective of the current research was to identify whether contrasting levels of winter biomass in …

Extending The Grazing Season With Turnips, P. Thomet, S. Kohler Feb 2023

Extending The Grazing Season With Turnips, P. Thomet, S. Kohler

IGC Proceedings (1977-2023)

A comparison of the actual feeding costs on 86 typical Swiss dairy farms confirmed that the production of hay and grass silage is very expensive with costs from the field to intake in the range of 20-25 Euro cents/kg of dry matter (DM). Options to extend the grazing season for dairy cows in the late autumn and early winter, and hence reduce winter feeding costs, would therefore be welcome (Penrose et al., 1996). The aim of the study was to compare the DM production potential of summer-seeded turnips with other brassicas and Italian ryegrass and to test whether dairy cows …

Milk Production Performance Based On Grazed Grassland In Switzerland, P. Thomet, H. Menzi Feb 2023

Milk Production Performance Based On Grazed Grassland In Switzerland, P. Thomet, H. Menzi

IGC Proceedings (1977-2023)

A common feature of profitable dairy systems is the use of large amounts of low cost feed. One approach to improve the competitive ability of the dairy production therefore is to promote grazing (Dillon et al., 1995). A comparison of the actual feeding costs on typical Swiss dairy farms showed that hay and grass silage were four times and concentrates seven times more expensive than grazed grass. A maximum utilisation of grazed grass can be achieved with a seasonal production system, which synchronises the cow’s feed requirements with pasture growth. This strategy was implemented and consistently optimised on an …

The Effect Of Inclusion Of A Range Of Supplementary Feeds On Herbage Intake, Total Dry Matter Intake And Substitution Rate In Grazing Dairy Cows, S. J. Morrison, D. C. Patterson, S. Dawson, C. P. Ferris Feb 2023

The Effect Of Inclusion Of A Range Of Supplementary Feeds On Herbage Intake, Total Dry Matter Intake And Substitution Rate In Grazing Dairy Cows, S. J. Morrison, D. C. Patterson, S. Dawson, C. P. Ferris

IGC Proceedings (1977-2023)

The milk production potential of dairy cows has increased substantially over the past two decades. This development presents new challenges for managing dairy cows during grazing, particularly where the objective is to maximise the proportion of energy in the diet derived from forage. The objective of the current study was to explore supplementation strategies to maintain high total forage intakes from grazed grass supplemented with alternative forage supplements in dairy cows during the grazing season. A second objective of the study was to examine the effect of supplement on substitution rate (SR) and milk yield response.

White Clover Soil Fatigue: An Establishment Problem On Large And Intensive Dairy Farms, K. Søegaard, K. Møller Feb 2023

White Clover Soil Fatigue: An Establishment Problem On Large And Intensive Dairy Farms, K. Søegaard, K. Møller

IGC Proceedings (1977-2023)

In recent years a new constraint, clover soil fatigue, has appeared for the establishment of white clover (Trifolium repens) in Denmark. Increasing dairy farm size has led to more intensive use of clover in crop rotation schemes in the grazing areas located at convenient distances from stables. It has become common practice to establish new clover/grass in the fields just after ploughing clover/grass swards, and soil fatigue is becoming more common. On fatigued land the clover plants emerge, then become stunted and eventually disappear within the same year. The problem tends to cover the full field area. Obviously, …

Loving Blackness: A Sense Experience, Ricardo J. Millhouse Feb 2023

Loving Blackness: A Sense Experience, Ricardo J. Millhouse

Feminist Pedagogy

The late bell hooks framed feminist pedagogies as a set of practices and systems that provide a description of feminism, a feminist learning environment, and ways to cultivate a community that is ready for feminist instruction. Using intersectionality, hooks (1992) discussed “loving blackness” as a representational and destabilizing practice to de-center whiteness. hooks (1992, 20) writes, “loving blackness as a political resistance transforms our ways of looking and being, and thus creates conditions necessary for us to move against the forces of domination and death and reclaim black life.” I propose a black feminist praxis teaching tool, “a sense experience,” …

Academic Spaces Of Possibility? A Proleptic Dialogue With Blackfeminism At The Center, Liliana Herakova, Lauren O. Babb, Kevin Roberge Feb 2023

Academic Spaces Of Possibility? A Proleptic Dialogue With Blackfeminism At The Center, Liliana Herakova, Lauren O. Babb, Kevin Roberge

Feminist Pedagogy

This critical commentary engages our experiences as co-educators in a “Black Feminist Thought and Expression” (BFTE) course, first-of-its-kind at our predominantly white institution in the U.S.. We imagine and provoke redefinitions of “classrooms” and “students” toward the liberatory dialogic learning bell hooks continues to inspire. We reflect on the potentials and perils of BFTE as pedagogical moves toward 1) becoming learners over and over again and 2) creating multiple different learning spaces, not confined to the physical classroom or to texts-as-usual. By bringing our beings together in both this essay and in BFTE, we re-member the dialogic pedagogy of love-as-action …

Black Feminist Pedagogy In White Southern Spaces, Frances B. Henderson Feb 2023

Black Feminist Pedagogy In White Southern Spaces, Frances B. Henderson

Feminist Pedagogy

In Teaching to Transgress, bell hooks situates the classroom as “the most radical space of opportunity in academia” (hooks 1994,), as it is within this space that we might challenge and transcend ways of knowing centered in patriarchy, sexism and racism. But what happens when the classroom is located in spaces loyal to the historical frameworks that buttress white supremacist heteropatriarchy? This article examines my twelve years of experience in teaching undergraduate courses in political science at a small liberal arts college in the mid-South. At its center are critical reflections on attempts to formulate and employ a black feminist …

How I Learned To Love Teaching: Bell Hooks And The Possibilities Of The Feminist Classroom, Patti Duncan Feb 2023

How I Learned To Love Teaching: Bell Hooks And The Possibilities Of The Feminist Classroom, Patti Duncan

Feminist Pedagogy

In this critical commentary, I describe the influence bell hooks has had on my pedagogy since first reading her book, Teaching to Transgress: Education as the Practice of Freedom, when I was a graduate student in Women’s and Gender Studies in the 1990s. The profound influence hooks’ work had on me, as a first generation, woman of color scholar from a working-class background, cannot be overstated. Her words helped me name and begin to critique and resist the isolation, alienation, and oppressive systems that had, up to that point, shaped my experience and the experience of many women of color …

Engaged Pedagogy And Journaling: A Pathway To Self-Transformation, Maria Guajardo Feb 2023

Engaged Pedagogy And Journaling: A Pathway To Self-Transformation, Maria Guajardo

Feminist Pedagogy

Journaling, a reflective teaching activity, is an approach for engaged learning that allows students to find one’s voice, reexamine one’s identity, and create a deeper understanding of self, identity, and agency. Central to bell hooks’ feminist pedagogy is engaged teaching and learning, a pathway that allows learner and teacher to actively question what is and what must be (hooks, 1994). This learning-teaching space examined the intersecting topics of gender, culture, and leadership by unlearning, learning, and relearning one’s understanding and experience of these three identities. The main learning objectives of this teaching activity were to 1) engage in critical inquiry; …

Playing With Privilege: A Creative Way For Students To Unpack Privilege, Ashley D. Garcia Feb 2023

Playing With Privilege: A Creative Way For Students To Unpack Privilege, Ashley D. Garcia

Feminist Pedagogy

Although privilege is a foundational concept in many courses, students often have only a vague notion of it, which hinders discussion and analysis. This activity/assignment, grounded in bell hooks' engaged pedagogy, tasks students with visually representing and explaining a concrete instance of privilege to their peers. Through creating comic strips, students must interrogate their assumptions of privilege and begin to encounter its intersectional structure. Creating comic strips that depict privilege helps students grasp the concept and apply it in their self-reflection. Moreover, this establishes a foundation from which students can interrogate the positions of privilege that structure their social realities.

Resisting Burnout: Bell Hooks’ Pedagogy Of Hope And Teaching Antiracist Feminism Online At The University Of Wyoming During The Covid-19 Pandemic, Samantha L. Vandermeade Feb 2023

Resisting Burnout: Bell Hooks’ Pedagogy Of Hope And Teaching Antiracist Feminism Online At The University Of Wyoming During The Covid-19 Pandemic, Samantha L. Vandermeade

Feminist Pedagogy

After earning a PhD in Women’s Studies from an urban, multicultural, R1 university in 2020, I accepted a teaching position at the University of Wyoming, where I was hired primarily to teach feminist and critical race-focused courses. When an in-person position suddenly moved entirely online, I found myself facing not only the culture shock of teaching at a rural, primarily White institution whose state legislature and general populace are largely hostile to antiracist feminism, but also the myriad daily challenges of teaching online during a global pandemic. I had felt personally prepared--as a White lesbian raised in a rural environment, …

Effect Of Farm Grass Cover At Turnout On The Grazing Management Of Spring Calving Dairy Cows, M. O'Donovan, L. Delaby, P. Defrance Feb 2023

Effect Of Farm Grass Cover At Turnout On The Grazing Management Of Spring Calving Dairy Cows, M. O'Donovan, L. Delaby, P. Defrance

IGC Proceedings (1977-2023)

Early spring grazing is an objective for most Irish dairy farmers. If more grass is included in the diet of the cow in early lactation, the profitability of the farm system can be increased. Post turnout, dairy cow feeding management varies with the amount of farm grass cover (FC) available. Experiments on the consequences of different FC at turnout require large resources and all scenarios cannot be accounted for. Consequently, a decision support system, Pâtur’IN (Delaby et al., this volume), was used to describe the effects of various FC at turnout on grazing management in spring.

What Supplementation Type For Spring Calving Dairy Cows At Grass In Autumn?, M. O'Donovan, E. Kennedy, T. Guinee, J. J. Murphy Feb 2023

What Supplementation Type For Spring Calving Dairy Cows At Grass In Autumn?, M. O'Donovan, E. Kennedy, T. Guinee, J. J. Murphy

IGC Proceedings (1977-2023)

In spring-calving herds the requirement for conserved forages for indoor feeding is very limited but these feeds may have a role to play as buffer feeds in the spring and autumn periods when grass supply is less than required or as alternatives to concentrates on pasture for cows in early lactation. The objective of this experiment was to compare alternative forages and concentrates as buffer feeds on pasture with spring-calving cows in the autumn.

Manipulation Of Grass Growth Through Strategic Distribution Of Nitrogen Fertilisation, M. Stettler, P. Thomet Feb 2023

Manipulation Of Grass Growth Through Strategic Distribution Of Nitrogen Fertilisation, M. Stettler, P. Thomet

IGC Proceedings (1977-2023)

The objective of this study was to evaluate possibilities and limits of manipulating the grass growth of pastures by different nitrogen (N) application strategies with the aim to better synchronise grass supply and feed demand. In Switzerland, the use of N is strongly restricted by legislation. An efficient and well allocated N fertilisation is therefore important.

A Comparison Of Three Systems Of Milk Production With Different Land Use Strategies, L. Shalloo, P. Dillon, J. J. Murphy Feb 2023

A Comparison Of Three Systems Of Milk Production With Different Land Use Strategies, L. Shalloo, P. Dillon, J. J. Murphy

IGC Proceedings (1977-2023)

Under the Luxemburg agreement FAPRI-Ireland (Breen & Hennessey 2003) projects that milk price will decrease by 5.0 to 5.5 c/l because of reductions in support for butter and skimmed milk powder. These changes mean that many dairy farmers need to reappraise their systems of milk production and consider necessary adjustments that will ensure viability in the longer term. The objective of this study was to model three different systems of milk production in scenarios where quota, cow numbers or land was restricted.

Project Opti-Milk: Optimisation And Comparison Of High Yield And Low Input Milk Production Strategies On Pilot Farms In The Lowlands Of Switzerland, H. Menzi, T. Blaettler, P. Thomet, B. Durgiai, S. Kohler, R. Staehli, R. Mueller, P. Kunz Feb 2023

Project Opti-Milk: Optimisation And Comparison Of High Yield And Low Input Milk Production Strategies On Pilot Farms In The Lowlands Of Switzerland, H. Menzi, T. Blaettler, P. Thomet, B. Durgiai, S. Kohler, R. Staehli, R. Mueller, P. Kunz

IGC Proceedings (1977-2023)

Compared to other European countries milk production costs in Switzerland are high. Therefore Swiss milk producers must drastically reduce their costs. The high yield strategy (HY) and the full grazing (FG) or low-cost strategy appear most promising, at least for the lowland regions. Although the basic knowledge is available for both strategies, they have been applied very little in Switzerland in a consistent and optimised form.

Assessment Of Grass Production And Efficiency Of Utilisation On Three Northern Ireland Dairy Farms, A. J. Dale, P. D. Barrett, C. S. Mayne Feb 2023

Assessment Of Grass Production And Efficiency Of Utilisation On Three Northern Ireland Dairy Farms, A. J. Dale, P. D. Barrett, C. S. Mayne

IGC Proceedings (1977-2023)

Recent research has shown that grazed grass can be an expensive forage for milk production, particularly if herbage production is low or utilisation is inefficient. There is very limited data on the level of herbage grown and utilised on commercial farms. The objective of this project was to quantify grass production and efficiency of utilisation on farm to substantiate the potential of grazed grass for profitable milk production.

The Effect Of Grassland Management On Bovine Nitrogen Efficiency, N. J. Hoekstra, R. P. O. Schulte, E. A. Lantinga, P. C. Struik Feb 2023

The Effect Of Grassland Management On Bovine Nitrogen Efficiency, N. J. Hoekstra, R. P. O. Schulte, E. A. Lantinga, P. C. Struik

IGC Proceedings (1977-2023)

Nitrogen (N) losses through grazing bovines are at the heart of the current debate on environment and agriculture. N utilisation of grazing bovines is predominantly determined by the form and amount of energy and protein in their diet, which in Ireland consists mainly of grazed grass. The two main problems of grazed grass with respect to animal N utilisation are 1) the imbalance between total N content and energy content, and 2) the lack of synchronisation between the release of N and carbohydrates in the rumen. It was hypothesised that both the balance and synchronisation of N and energy in …

The Effect Of Stocking Rate And Initial Grass Height On Herbage Production And Utilization, And Milk Production Per Unit Area Under Set Stocking By Lactating Dairy Cows, H. Nakatsuji, T. Endo, S. Bawm, T. Mitani, M. Takahashi, K. Ueda, S. Kondo Feb 2023

The Effect Of Stocking Rate And Initial Grass Height On Herbage Production And Utilization, And Milk Production Per Unit Area Under Set Stocking By Lactating Dairy Cows, H. Nakatsuji, T. Endo, S. Bawm, T. Mitani, M. Takahashi, K. Ueda, S. Kondo

IGC Proceedings (1977-2023)

In our previous study with lactating dairy cows (Nakatsuji et al., 2004), annual herbage production and utilization, and milk production per unit area under set stocking was not always lower than under rotational grazing at the same stocking rate (6 cows/ha). Furthermore, there was a possibility that set stocking could increase pasture utilization and milk production over rotational grazing when cows were grazed at adequate stocking rate and at the appropriate initial date of grazing. The purpose of the present study was to evaluate the effect of stocking rate and initial grass height on herbage production and utilization, and …

Better Dairy Farm Management Increases The Economic Return From Phosphorus, J. D. Morton Feb 2023

Better Dairy Farm Management Increases The Economic Return From Phosphorus, J. D. Morton

IGC Proceedings (1977-2023)

Some 60% of New Zealand dairy farms on allophanic and sedimentary soils have soil Olsen phosphorus (P) levels to 75 mm depth above the target range for near-maximum pasture production of 20-30 µg/ml (Roberts & Morton 1999). For an economic response in milksolids (MS) production from high Olsen P, the pasture needs to be capable of high production, and the extra pasture grown be converted to milk. This paper seeks to justify this contention and outline some of the farm management practices required to achieve it.

The Effect Of Two Magnesium Fertilisers, Kieserite And Mgo, On Herbage Mg Content, M. B. O'Connor, A. H. C. Roberts, R. Haerdter Feb 2023

The Effect Of Two Magnesium Fertilisers, Kieserite And Mgo, On Herbage Mg Content, M. B. O'Connor, A. H. C. Roberts, R. Haerdter

IGC Proceedings (1977-2023)

Supplementing Mg to dairy cows is widely practised in New Zealand. Various methods are used including drenching, pasture dusting, water trough treatment and adding to hay, silage and other feedstuffs (Young et al., 1979). Fertiliser Mg (calcined magnesite, MgO) is widely used to maintain soil Mg status but research has shown that using fertiliser Mg to achieve good soil, pasture and animal Mg status requires large inputs of Mg (120 kg/ha) and maintaining blood serum Mg status in dairy cows tends to be short-lived without further animal supplementation (O’Connor et al., 1987). The objective of these experiments was …
