From Initial Opportunities To The Awakening: A Paradoxical View Of The Rise Of Women's Literature, Rebecca Christensen Feb 2024

From Initial Opportunities To The Awakening: A Paradoxical View Of The Rise Of Women's Literature, Rebecca Christensen

The Thetean: A Student Journal for Scholarly Historical Writing

The 1800s saw the broadening of the female press with an expanded audience and increasing numbers of women writers. These women, following the admonition of Sarah Hale, emphasized the role of women as defenders of morality. Women, they believed, functioned in a separate sphere and their writing stressed women's proper place in family and home environments. The strong literary foundation created by the success of these women, however, paradoxically lead to the emergence of Kate Chopin, whose works reject the conventional model of women as the ideal of virtue and demonstrate women's needs as an individuals.

Wheat Landraces, Small Farmers And Urban Consumers: Revival Of Einkorn In Turkey, Nurcan Atalan Helicke Feb 2024

Wheat Landraces, Small Farmers And Urban Consumers: Revival Of Einkorn In Turkey, Nurcan Atalan Helicke

Journal of Critical Global Issues

Cultivated for more than 10,000 years, wheat (Triticum) is one of the world’s most widely grown and important crops. Wheat has sustained humans for thousands of years in a multitude of ways. In recent years, there has been a global movement to revive wheat landraces. Landraces are typically adapted to a local area and to traditional farming systems. This article examines the revival of wheat landrace, einkorn (Triticum monoccoccum L. subsp. monoccoccum) through a case study of Turkey. There is limited literature examining the interaction of actors in decision-making processes that balance subsistence and market motivations. …

Use Of The Grazing Animal In Forage Breeding, J H. Bouton, C S. Hoveland, R N. Gates Feb 2024

Use Of The Grazing Animal In Forage Breeding, J H. Bouton, C S. Hoveland, R N. Gates

IGC Proceedings (1977-2023)

The objective of these studies was to determine, in the context of a forage breeding program, the effect of cattle grazing on survival of alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), and tall fescue (Festuca arundinacea Schreb.). Different cultivars of each species were compared in grazed and ungrazed areas. Results consistently demonstrated that grazing reduced plant stands when compared to ungrazed conditions for each species tested. In alfalfa, however, cultivars developed for grazing tolerance showed much better grazing survival. Infection with the fungal endophyte, Acremonium coenophialum Morgan-Jones & Gams, likewise substantially increased grazing survival in …

Selection Of Stylosanthes Guianensis For The Cerrados Of Brazil, B Grof, C D. Fernandes, A V. Dos Santos, C B. Almeida

IGC Proceedings (1977-2023)

Progenies of intervarietal hybrid stylos (Stylosanthes guianensis var.vulgaris x S.guianensis var.pauciflora) with mid-season maturity date (early-and mid-June), high dry matter and seed yields have been identified at the National Beef Cattle Research Center (CNPGC), Campo Grande, MS, Brazil. Dry matter yields of the best selections were comparable to those of the late-flowering control, cv. Mineirão. Several mid-season hybrids produced 150 to 200 kg/ha of seed-inpod and a single plant selection yielded in excess of 300 kg/ha. The high degree of resistance to anthracnose observed in the advanced generations is attributed to the immense genetic diversity of these …

Ruminal Fill Effect Of Forages: Prediction And Relationship With Voluntary Intake, R Baumont, A Barlet, J Jamot Feb 2024

Ruminal Fill Effect Of Forages: Prediction And Relationship With Voluntary Intake, R Baumont, A Barlet, J Jamot

IGC Proceedings (1977-2023)

Voluntary dry matter intake (VDMI) and rumen fill were measured on sheep fed with 18 forages ranging from wheat straw to lucerne hay. In vivo fill effect (IVFE i.e. rumen DM pool divided by VDMI), in situ degradability, cell-wall composition, pepsin-cellulase digestibility and in vitro gas production were determined. In situ estimated fill effect (ISFE) was calculated as the retention time of insoluble potential degradable and undegradable fractions using a constant rate of passage. ISFE and IVFE were highly correlated (r2=0.89) but ISFE values were lower than IVFE values because in situ degradability does not integrate comminution time of …

Modeling Intake Of Grazing Cows Fed Complementary Feeds, D R. Buckmaster, L A. Holden, L D. Muller, R H. Mohtar Feb 2024

Modeling Intake Of Grazing Cows Fed Complementary Feeds, D R. Buckmaster, L A. Holden, L D. Muller, R H. Mohtar

IGC Proceedings (1977-2023)

A model suitable for predicting intake for grazing or non-grazing dairy cows is presented. The model integrates the potentially intake limiting factors of physical fill, physiological energy demand, wet mass, herbage availability, herbage cover, and grazing time. Integration of these factors with a simple set of linear ration balancing constraints yields a model suitable for predicting supplemental feed requirements as well as potential animal production from a grazed land. The model is semi-theoretical, being descriptive in structure, but containing empirical relationships.

Intake And Partial Digestibility Of Panicum Maximum (Cv. Gatton) At Three Stages Of Maturity During Summer, W.A. Van Niekerk, N F.G. Rethman

IGC Proceedings (1977-2023)

The objective of this study was to determine the influence of stage of maturity on the intake and digestibility of P. maximum (cv. Gatton) during the active growing season. Low DM content at the young and medium growth stages (24.9 and 25.2%) did not hamper DOMI (48.8 and 44.1 g/kg W0.75/d) respectively. The N concentration of the three stages were well within the limit required for optimal rumen microbial production (1.8 - 2.0%). The high NDF value of the adult stage (59.5%) resulted in a significantly lower IVDOM value (62.3%) but the IVDOM values of all stages were on the …

Implications Of Biomechanical Characters Of Subterranean Clover On Feeding By Redlegged Earth Mite And Intake By Sheep, D A. Henry, S K. Baker, T J. Ridsdill-Smith Feb 2024

Implications Of Biomechanical Characters Of Subterranean Clover On Feeding By Redlegged Earth Mite And Intake By Sheep, D A. Henry, S K. Baker, T J. Ridsdill-Smith

IGC Proceedings (1977-2023)

The biomechanical strength of cultivars of subterranean clover (Trifolium subterraneum) that were either resistant or susceptible to feeding by redlegged earth mite was measured as the force required to penetrate their leaves with a small, tubular punch. Cotyledons and trifoliate leaves of cultivars resistant to redlegged earth mite had a higher resistance to penetration than cultivars susceptible to redlegged earth mite. Cotyledons needed a higher force to penetrate than trifoliate leaves. The possible implications for intake by ruminants of differences between the cultivars in biomechanical characters are also considered.

High Instantaneous Spring Stocking Rates To Improve Year Round Herbage Utilization In Argentine Dairy Production, M H. Wade, D E. Dalla Valle

IGC Proceedings (1977-2023)

In much of Buenos Aires Province, Argentina 60% of the year’s pasture production occurs during spring. This trial was carried out to test the minimum area necessary for grazing in the period of maximum pasture growth in the 3 to 4 months of spring, so that in turn the maximum potential area for forage conservation could be estimated. At the two levels of herbage allowance aimed for (achieving 18.1 and 36.6 kgDM/cow/d), herbage intake was 11.1 and 13.4 kgDM/cow/d and milk production 20.9 and 22.3 l/cow/d respectively. While these differences were not significant, the trial demonstrated a potential of 70 …

The Effect Of Sward Height And Bulk Density On Herbage Intake And Grazing Behaviour Of Dairy Cows, C S. Mayne, D Mcgilloway, A Cushnahan, A S. Laidlaw Feb 2024

The Effect Of Sward Height And Bulk Density On Herbage Intake And Grazing Behaviour Of Dairy Cows, C S. Mayne, D Mcgilloway, A Cushnahan, A S. Laidlaw

IGC Proceedings (1977-2023)

The effects of sward height and bulk density on herbage intake and grazing behaviour of dairy cows during 1 hour grazing periods was investigated. Sward factors had a marked effect on dry matter (DM) intake/bite, which ranged from 0.4 to 1.1 g, and this was reflected in hourly intake rates. Intake/bite was largely influenced by sward height, reflecting increased bite depth in taller swards, with inherent differences between swards at low sward heights largely attributable to differences in bulk density (BD). The results indicate that DM intake rates up to 4.0 kg DM/hour can be achieved in short term grazing …

IGC Proceedings (1977-2023)

The objective of this study was to compare the composition and degradation characteristics of early bloom alfalfa and fenugreek harvested after 9, 15 and 17 wk of growth. Crude protein (CP) content of fenugreek cut at 9, 15 and 17 wk was lower (P<0.05) than that of alfalfa. Neutral detergent fibre (NDF) and lignin content of fenugreek harvested after 15 and 17 wk were higher (P<0.05) than that of alfalfa. Ash content was lower (P<0.05) in fenugreek than for alfalfa. In vitro dry matter disappearance (IVDMD) of fenugreek cut at 15 and 17 wk was similar to that of alfalfa. Total in vitro gas production of fenugreek cut at the three stages of growth was not significantly different from those observed for alfalfa. Results indicate that chemical composition and IVDMD of fenugreek at all stages of …
