IGC Proceedings (1977-2023)

To investigate availability of major elements to animals, N, P, K, Ca and Mg of plant dry matter were partitioned into 4 cell fractions based on enzyme solubility. When the elemental concentration of forage was compared, Dactylis glomerata was higher in K (1.69%), Festuca aru11dinacea in N (2.35%), K (1.68%) and Mg (Q.341 %) and Lolimum perenne in N (2.54%), P (0.224%) and Ca (0.457%). When compared between plant parts, concentrations of all elements.were higher in leaf than in stem, especially P, Ca and Mg. As a result of partitioning, more than 85% of P, K and Mg resided …

Improvement Of The Feeding Value Of Senescent Grass Pastures By Molecular Genetic Manipulation, G D. Bonnett, K R. Stevenson, R J. Simpson

IGC Proceedings (1977-2023)

Senescent grass pasture has low feeding value end is the major limitation to animal productivity during summer in annual environments. The loss of fructan from the stems of temperate grasses as they senesce contributes significantly to the decline in feeding value of the grass, Temporary retention of fructan during senescence achieved by treating grass with a herbicide increases both the feeding value of the grass and the productivity of animals grazing the modified pasture. We have identified an enzyme responsible for initiating the loss of fructan from stems of Lolium rigidum. It has been purified, characterized and will be used …

Modeling The Effects Of Climate Variability And Climate Change On A Pastoral Farming System, R J. Martin, D B. Baird, M J. Salinger, P R. Van Gardingen, D G. Mccall

IGC Proceedings (1977-2023)

A simulation model was used to investigate the pasture and animal production and gross margins of a typical all sheep permanent pasture farm in South Canterbury, New Zealand, using 60 years of current climate data, and also a climate change scenario. The model was run on a fixed management system at different stocking rates with and without destocking during feed shortages. Mean annual pasture production was 8060 kg/ha, with a coefficient of variation of 22%. Destocking enabled more stock to be carried on average, with higher, but rh.ore variable, returns. A climate change scenario of a 75% increase in CO2' …

Effects Of Defoliation Height And Time Of Initital Defoliation On Regrowth Components In A Poa Pratensis- Dominated Sward, B E. Frankow-Lindberg

IGC Proceedings (1977-2023)

Two experiments on swards dominated by Poa pratensis L. were conducted in 2 climatically contrasting (wann/dry and cold/wet) years. There were either 4 or 3 initial defoliation dates in spring and 3 defoliation heights (2, 6 and 10 cm). Regrowths were harvested 4 weeks after the initial defoliation. The swards received a total of 80 kg/ha nitrogen split into 2 dressings. Regrowth characteristics, based on samples cut to ground level, depended on weather conditions. The yield of vegetative shoots was affected most by shoot size, which in turn was determined by initial defoliation date, in the dry year. In the …

IGC Proceedings (1977-2023)

The innuence of continuous grazing management on leaf extension, leaf senescence and tiller density of 3 grass species with contrasting tillering rates, tiller size and growth habit was examined. Perennial ryegrass (Lolium perenne L. cv. Grasslands Nui), tall fescue (Festuca arundinacea Schreb, cv. Grasslands Roa) and Yorkshire fog (Holc,,s la11allls L. cv. Massey Bnsyn) were maintained in as near a steady state as possible at sward heights of 3-10 cm. The balance between leaf extension and senescence, and tiller density resulted in net extension per unit area being generally greatest at sward heights of- 5.5 cm in Yorkshire fog and …

Applications Of Random Amplified Polymorphic Dna (Rapd) Markers In Plant Biology, Gail M. Timmerman, John A. Mccalum

IGC Proceedings (1977-2023)

RAPDs are a new class of molecular marker based on PCR amplification of genomic DNA using random sequence primers. Their value for studying plant genomes has been clearly demonstrated in the short lime they have been in use. Uses of RAPD markers include genome mapping, lagging of genes, studying genetic diversity, identifying cultivars and analysing parentage. RAPDs should prove to be as applicable to the study of animal genomes ns they have for plant genomes, It is important that researchers using or planning to use this type of molecular marker be aware of two possible drawbacks of RAPDs. Since RAPDs …

A Traditional Exporter's Perspective Of Trade Reforms, N R. Mitchell

IGC Proceedings (1977-2023)

The agriculture and trade policies which governments commonly have pursued over the last three decades, particularly governments in the large developed countries, have had a major impact on world patterns of production and trade in livestock and livestock products. This has been especially so for milk and dairy products where government involvement in markets has been most pervasive. One effect has been that the comparative advantages derived from the production of livestock products based on pasture feeding of animals \lave been suppressed or overridden. Reform of the international trading system for agricultural products now being developed in the GATT, and …

Impact Of Changing Trade Opportunities On Livestock Production In Developing Countries, J K. Camoens

IGC Proceedings (1977-2023)

For the lesser developed countries (LDCs) and advanced countries (ACs), the paper identifies the determinants of "free" trade, analyses protectionism, examines the global trade picture with respect lo "free" trade, relates trade to production and the structure of demand, and finally predicts the impact of trade reforms. The analysis concludes that: (i) trade policies per se do not impact in any significant manner on domestic production or imports in the LDCs since world trade constitutes a small fraction of production; (ii) demand, and hence supply, of animal products are determined primarily by GNP, income distribution and price; (iii) grassland farming …

Glycerol-Free Biodiesel Via Catalytic Interesterification: A Pathway To A Netzero Biodiesel Industry, Nessren Farrag, Omar Youssef Youssef, Esraa Khaled, Omar Aboelazayem

Chemical Engineering

Conventional biodiesel manufacturing uses alcohol as an acyl acceptor, resulting in glycerol as a side product. The increased demand for biodiesel has led to the production of a substantial surplus of glycerol, exceeding the market need. Consequently, glycerol is now being regarded as a byproduct, and in some cases, even as waste. The present study aims to suggest an economically viable and ecologically friendly approach for maintaining the viability of the biodiesel sector. This involves generating an alternative byproduct of higher value, rather than glycerol. Triacetin is produced through the interesterification of triglycerides with methyl acetate, and is a beneficial …

Use Of Pulsed Electric Fields And Hydrogen Peroxide For Pre And Postharvest Strategies To Reduce Microbial Loads On Fresh Produce, Zachary Rosenzweig

Theses and Dissertations

Several issues exist within the agricultural industry surrounding failure to prevent pathogen transfer to plants preharvest and failure to decontaminate foods postharvest. Fresh produce, like leafy greens, pose a large threat to public safety if contaminated because they are minimally processed and often eaten raw. Numerous outbreaks have been linked to fresh produce in recent decades, with irrigation water emerging as a potential source. These outbreaks have severe economic repercussions and can contribute to millions of hospitalizations and deaths each year, worldwide. This thesis focuses on the usage of pulsed electric fields (PEF) and hydrogen peroxide (H2O2) as a means …

Oxa-Iboga Alkaloids Lack Cardiac Risk And Disrupt Opioid Use In Animal Models, Václav Havel, Amanda Hunkele, Rohini S Ople, Susruta Majumdar, Et Al.

2020-Current year OA Pubs

Ibogaine and its main metabolite noribogaine provide important molecular prototypes for markedly different treatment of substance use disorders and co-morbid mental health illnesses. However, these compounds present a cardiac safety risk and a highly complex molecular mechanism. We introduce a class of iboga alkaloids - termed oxa-iboga - defined as benzofuran-containing iboga analogs and created via structural editing of the iboga skeleton. The oxa-iboga compounds lack the proarrhythmic adverse effects of ibogaine and noribogaine in primary human cardiomyocytes and show superior efficacy in animal models of opioid use disorder in male rats. They act as potent kappa opioid receptor agonists …

Stardust: A Pipeline For The Unbiased Analysis Of Astrocyte Regional Calcium Dynamics, Yifan Wu, Yanchao Dai, Katheryn B Lefton, Timothy E Holy, Thomas Papouin

2020-Current year OA Pubs

Calcium imaging has become a popular way to probe astrocyte activity, but few techniques holistically capture discrete calcium signals occurring across the astrocyte domain. Here, we introduce STARDUST, a pipeline for the spatio-temporal analysis of regional dynamics and unbiased sorting of transients from fluorescence recordings of astrocytes. We describe steps for installing software, detecting active pixel patches, obtaining region of activity (ROA) maps, and extracting time series from ROAs. We then detail procedures for extracting signal features using custom-made code.

Cyp1b1-Rmdn2 Alzheimer's Disease Endophenotype Locus Identified For Cerebral Tau Pet, Kwangsik Nho, Muhammad Ali, Tammie Benzinger, Carlos Cruchaga, Diana Hobbs, Et Al.

2020-Current year OA Pubs

Determining the genetic architecture of Alzheimer's disease pathologies can enhance mechanistic understanding and inform precision medicine strategies. Here, we perform a genome-wide association study of cortical tau quantified by positron emission tomography in 3046 participants from 12 independent studies. The CYP1B1-RMDN2 locus is associated with tau deposition. The most significant signal is at rs2113389, explaining 4.3% of the variation in cortical tau, while APOE4 rs429358 accounts for 3.6%. rs2113389 is associated with higher tau and faster cognitive decline. Additive effects, but no interactions, are observed between rs2113389 and diagnosis, APOE4, and amyloid beta positivity. CYP1B1 expression is upregulated in AD. …

Using the Xishuangbanna World Biosphere Reserve as a case study, the joint efforts between China and Laos are examined, and the effectiveness in the …

Tumor-Infiltrating Nerves Functionally Alter Brain Circuits And Modulate Behavior In A Mouse Model Of Head-And-Neck Cancer, Jeffrey Barr, Austin Walz, Anthony C Restaino, Moran Amit, Sarah M Barclay, Elisabeth G Vichaya, William C Spanos, Robert Dantzer, Sebastien Talbot, Paola D Vermeer

Faculty, Staff and Student Publications

Cancer patients often experience changes in mental health, prompting an exploration into whether nerves infiltrating tumors contribute to these alterations by impacting brain functions. Using a mouse model for head and neck cancer and neuronal tracing, we show that tumor-infiltrating nerves connect to distinct brain areas. The activation of this neuronal circuitry altered behaviors (decreased nest-building, increased latency to eat a cookie, and reduced wheel running). Tumor-infiltrating nociceptor neurons exhibited heightened calcium activity and brain regions receiving these neural projections showed elevated Fos as well as increased calcium responses compared to non-tumor-bearing counterparts. The genetic elimination of nociceptor neurons decreased …
