Influence Of Different Alfalfa-Grass Mixtures And The Use Of Additives On Nutritive Value And Fermentation Of Silage, P. Lättemäe, U. Tamm

IGC Proceedings (1977-2023)

Legumes have a high nutritive value but they are known to be difficult to ensile and often result in poorly fermented silage. This is usually due to high buffering capacity and low available sugar concentration. However, the results have shown that silage quality can considerably be improved by using additives or when legume-grass mixtures are ensiled (Lättemäe & Tamm, 2002). Different legume-grass mixtures differ in their ensiling properties and also may affect the fermentation. The objective of this experiment was to study the effect of alfalfa-grass mixtures and the use of additives on nutritive value and fermentation of silage.

Effects Of Inoculation Of Lab On Fermentation Pattern And Clostridia Spores In Easily Ensilable Grass Silages, J. Thaysen, G. Pahlow, E. Mathies

IGC Proceedings (1977-2023)

Clostridia can damage the protein quality of grass silages. They cause high gas losses during the fermentation process and quality problems in dairy products like semi-hard cheeses. In comparison to the effect of chemicals such as nitrite on undesirable clostridia in grass silages the respective inhibitory mechanism of LAB requires further investigation. The objective of this experiment was to study under laboratory conditions novel isolates of lactic acid bacteria (LAB), selected for their inhibitory effect on clostridia in grass silages.

Application Of A New Inoculant “Chikuso-1” For Silage Preparation Of Forage Paddy Rice, Y. Cai, C. Xu, S. Ennahar, N. Hino, N. Yoshida, M. Ogawa

IGC Proceedings (1977-2023)

Forage paddy rice is currently one of the most important silage crops in Japan. In fact, the use of paddy rice culture for silage production has been steadily increasing in recent years, not only because this represents a new way towards achieving self-sufficiency in animal feed, but also because of the interest of combining crop cultivation and livestock farming as a more effective use of idle paddy fields that often remain unused. However, the preparation of quality silage from paddy rice and its long-term storage are often challenging (Cai et al., 1999, 2003). In this study, a new bacterial …

IGC Proceedings (1977-2023)

Sugarcane has a high productive potential (30 t DM/year) and it is commonly used in its fresh form. The ensiling of sugarcane is increasing but little research has been carried out to reduce nutrient losses during fermentation.

Effects Of Stage Of Growth And Inoculation On Fermentation Quality Of Field Pea Silage, G. Borreani, L. Cavallarin, S. Antoniazzi, E. Tobacco

IGC Proceedings (1977-2023)

Field peas (Pisum sativum L.) are a short-term catch crop with a high crude protein content, which provides a high forage yield in a short growing period. Since field peas are a succulent crop and are difficult to field cure, it is preferable to directly ensile them to prevent weather damage and excessive grain losses. The onset of lodging is delayed in field pea varieties, since the crop is supported by the tendrils in a more erect manner, and this allows easy harvesting without soil contamination even at advanced stages of maturity (Koivisto et al., 2003). To …

Inoculant Effects On Ensiling And In Vitro Gas Production In Lucerne Silage, R. E. Muck, I. Filya, F. E. Contreras-Govea

IGC Proceedings (1977-2023)

Inoculants are the most common additives used in making silage. While inoculant effects on fermentation and dry matter (DM) recovery are understood, animal performance effects are often greater than expected. In vitro analyses may help uncover how inoculants affect rumen fermentation and ultimately dairy cattle performance. Our objective was to study how inoculation of lucerne silage affected in vitro gas production.

A Novel Bacterial Silage Additive Effective Against Clostridial Fermentation, E. Mayrhuber, M. Holzer, W. Kramer, E. Mathies

IGC Proceedings (1977-2023)

Silage quality is determined by factors including the content of butyric acid and ammonium-N. These parameters have to be restricted especially in lightly wilted silages due to a higher risk of clostridia contamination. In this study a novel silage additive was tested in grass silages of low dry matter content. The objective of this experiment was to explore the effect of the silage additive on quality parameters in comparison to an untreated control.

In Vitro Gas Production And Bacterial Biomass Estimation For Lucerne Silage Inoculated With One Of Three Lactic Acid Bacterial Inoculants, F. E. Contreras-Govea, R. E. Muck, I. Filya, D. R. Mertens, P. J. Weimer

IGC Proceedings (1977-2023)

Silages inoculated with microbial inoculants frequently have a lower pH than non-inoculated crops. Less often inoculated crops have a positive effect on milk production (Weinberg & Muck, 1996). One hypothesis is that bacterial inoculants produce a probiotic effect that could enhance animal performance (Weinberg & Muck, 1996). Our objective was to use the method of Blümmel et al. (1997) to study differences in in vitro fermentation among lucerne silages inoculated with three microbial inoculants.

Survey Of Tetraploid And Diploid Perennial Pastures In The Waikato For Number Of Spores Produced By The Fungus Pithomyces Chartarum, J. P. J. Eerens, W. W. Nichol, J. Waller, J. M. Mellsop, M. R. Trolove, M. G. Norriss

IGC Proceedings (1977-2023)

Facial eczema (FE) is a disease of livestock, caused by a toxin released into the bloodstream after digestion of spores of Pithomyces chartarum, a fungus residing in necrotic plant material in the base of pastures (di Menna & Bailey, 1973). Spore numbers tend to be highest in warm, humid conditions, where high post grazing residuals have lead to a build up of necrotic plant material. Tetraploid perennial ryegrass pastures tend to be more palatable, and with lower post gazing residuals, than equivalent diploid pastures; thus we hypothesised that spore numbers would be lower in tetraploid pastures. A survey of …

A Survey Of European Regional Adaptation In Italian Ryegrass Varieties, T. J. Gilliland, A. J. P. Wijk

IGC Proceedings (1977-2023)

Ryegrass is widely adapted to cool temperate eco-zones and breeders often submit individual varieties for testing in a number of EU countries. National testing programmes often combine data from several trial sites that may differ climatically, but not from sites in other member states, despite the possibility of high ecological similarity. Given increasing interest in ‘animal value’ characters (soluble sugars, lipids, sward geometry), additional testing for these would be valuable but is prohibited by capped or declining funding. Data sharing between EU national authorities could be advantageous but is inhibited by the lack of statistically valid data on the sensitivity …

Correlation Between Epiphytic Microflora And Microbial Pollution And Fermentation Quality Of Silage Made From Grasses, B. Osmane, J. Blūzmanis

IGC Proceedings (1977-2023)

Grass forage in Latvia is the main and inexpensive cow feed, however its composition and nutritive value differ during the growth period of grasses. The traits of grasses, their natural ensilage capacity, count of epiphytic microflora, the timing of harvest and ensilage making technology affecting the quality of grass silage are important issues to be studied. Silage making for the winter period is the treatment of green material to minimise the breakdown of nutrients being the results of biochemical and microbiological processes. The aim of the research was to clarify the methodologies to reduce the count of epiphytic microflora and …

Nerve Tissue Targeted Fluorophore Synthesis: From Scheme To Administration, Cassandra D. Mathieson

PSU McNair Scholars Online Journal

Nerve tissue damage as a result of surgical injury is a common negative outcome during many surgical interventions. Depending on the site of the injury and the amount of cellular damage, nerve tissue injury may potentially have a life altering effect on the surgical patient. Post-surgical nerve pain is often a chronic problem which persists long after injuries have healed, and can severely infringe upon quality of life for individuals.

Surgery that is fluorescence guided will aid in the visualization of nerve structure patterns, and as a result may significantly improve patient outcomes. Small molecule fluorophores may potentially cross the …

Perceptual Mismatch Between Meso And Macro Policy At Tokyo International University, Brianna M. Ross

PSU McNair Scholars Online Journal

Educational policies of Japanese institutions of higher education regarding English language instruction have looked at both macro and micro level variables. Through conducting interviews researchers gained knowledge of how or if institutions portray their standards to students and staff and how those goals are displayed through curriculum. This research showed a disconnect between the stated goals and in class instruction. While the researchers looked at overall disconnects, none looked at specific universities and their programs. My study aims to fill that gap, focusing on a university known for its international approach to learning. The intention is to find if there …

Survival In The City Streets: An Autoethnographic Analysis Challenging The Criminalization Of Urban Street Gangs, Robert Northman

PSU McNair Scholars Online Journal

To varying outcomes, many attempts have been made to understand and define urban street gangs. Though these understandings and definitions of gangs may vary, they almost always rely on criminality as at least one of the gang’s “purposes.” The author, a gang member for approximately thirty years seeks to contribute lived experiences to the conversation centered on gangs. This auto-ethnographic analysis of urban street gang culture seeks to highlight the author’s experiences as potential determinants of gang membership while also exacting the realities of some common myths and other misconceptions surrounding the urban street gang, including the criminalization thereof.

Invasive Plant Species And Their Impact On Stream Health Using Macroinvertebrates In The Willamette Valley, Oregon, Michelle Hesek, Patrick Edwards

PSU McNair Scholars Online Journal

Oregon spends approximately $83 million annually to maintain invasive plant species, which decreases resource availability for the environment and humanity. Their continued spread affects riparian zones, one of the most biologically diverse ecosystems that supplement stream and upland habitats. Some of the energy flow in these systems circulates by macroinvertebrates that decompose leaf litter during their immature stage of life. Upon metamorphosis, they rely on plants in riparian zones for reproductive habitat, making them prey to predators in stream and upland food webs, referred to as a transformational link. This research examines how invasive plant species affect stream health in …

The Effect Of Rhizophagus Intraradices Mycorrhizal Fungus On Iron Uptake Of Corn: A Global Overview On The Effects Of Climate Change On The Nutritional Content Of Crops, Caitlin R. Costello

PSU McNair Scholars Online Journal

Global iron deficiency is a major factor contributing to malnutrition and varied health conditions. One way to combat this is to maintain or increase the iron uptake of the globe’s major crops. Research has shown that certain types of mycorrhizal fungi can increase the nutrient uptake of plants. To further this research, we looked at the arbuscular fungi Rhizophagus intraradices and its potential relationship with the corn variety “Golden Bantam 8 Row”. This type of mycorrhizal fungi improves plant nutrition including the plant’s ability to source iron from the natural environment. Much of the iron found in the natural environment …

Creating Equitable And Inclusive Basic Course Classrooms: A Response Essay, Kristina Ruiz-Mesa, Melissa A. Broeckelman-Post

Basic Communication Course Annual

In 1992, Jo Sprague challenged communication educators to think more critically about how we teach and what we include in our communication curriculum. In the decades since Sprague’s powerful call for instructional communication researchers and instructors to ask ourselves, “What is knowledge and how is curriculum established?” (p. 11), we find ourselves needing to engage with ongoing contemporary conversations about what counts as knowledge in a basic communication course and which knowledge is viewed as important enough to include in the curriculum. A meta-synthesis of basic communication course surveys showed little change in the basic communication course content over the …
