Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Epigenetic Regulation Of Insect Development, Yaoyu Jiao

Theses and Dissertations--Entomology

Insects undergo a series of distinct life stages such as egg, larva and pupa to develop into mature adults capable of reproduction throughout their life cycle. In the larval stage, insects experience the fastest growth with voracious feeding and multiple cuticle shedding resulting in hundreds-of-fold increasing of size. During metamorphosis, insects stop increasing body size but go through dramatic tissue transformation, developing wings and other adult features. The characteristic mode of insect development, especially the metamorphosis, makes insects the most successful group of animals on the earth. However, the epigenetic mechanisms behind insect development remain elusive. Studying the epigenetic regulation …

Livestock Management In 2023 - 2024, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock published reports

Parts of WA have experienced below average rainfall resulting in feed limitations, with below average rainfall also predicted for the coming months. The feed shortage has been further compounded by limited slaughter space and reduced market prices for sheep.

Sheep industry economist, John Young, of Farming Systems Analysis Service was commissioned to look at the economics of some key decisions this season, taking into account current seasonal and market conditions.

WA sheep producers need to have plans in place early to monitor stock condition and make decisions about which classes of stock to keep. This will also include the feed …

Tedera is a resilient legume pasture that can fill feed gaps at a lower cost while offering livestock productivity gains.

Tedera: A Guide To Growing And Utilising This Perennial Pasture Legume, Daniel Real

Animal production and livestock published reports

The commercial release of a new pasture species is a rare and, potentially, important event. In the case of tedera (Bituminaria bituminosa var. albomarginata) we have a novel perennial pasture legume with characteristics which set it apart from anything currently available to growers in Australia or internationally.

Specifically, it is a drought-tolerant, highly productive perennial pasture with the capacity to provide nutritious forage, especially when other feed sources are scarce. Its reaction to drought is in contrast with the few successful perennial legumes available for Mediterranean climatic zones, such as lucerne, as it retains green leaves when water stressed, allowing …

Abiotic Stress Mitigation: A Case Study From 21 Trials Using A Natural Organic Matter Based Biostimulant Across Multiple Geographies, Rachel L. Sleighter, Terry Hanson, David Holden, Kristen M. Richards

Chemistry & Biochemistry Faculty Publications

Crop productivity and yields can be greatly diminished by abiotic stress events including drought, extreme temperatures, excess moisture, and saline irrigation water. Multiple stressors occurring simultaneously can further exacerbate the strain on plants. Various types of biostimulants have been shown to mitigate abiotic stress and here, the results of 21 trials on corn, wheat, soybean, and various high-value crops are discussed in the context of the abiotic stress that either occurred naturally or was experimentally induced. Treatments in these trials included stressed and non-stressed plants, as well as either an untreated control or grower standard fertilizer applications alone and in …

Genome-Wide Association Studies And Advanced Genomic Selection Strategies: Towards The Optimization Of Oat (Avena Sativa L) Breeding, Girma Ayana

Electronic Theses and Dissertations

Oats are important cereal crops worldwide, primarily valued for their nutritional and health benefits. The primary goal of oat breeding programs is to accelerate genetic gain to develop oat varieties with the desired product profiles, with the aim of meeting the needs and expectations of growers, processors, and consumers. Achieving this goal involves conducting extensive and resource-intensive field trials, particularly for traits such as crop yield and grain quality, which are strongly influenced by environmental factors. The availability of cost-effective molecular markers and tools like genome-wide association studies (GWAS) and genomic selection have the potential to accelerate the oat breeding …

Building No-Tillage Maize Nitrogen Recommendation Algorithm That Considers Improvements In Soil Health, Dwarika Bhattarai

Electronic Theses and Dissertations

In long-term no-till fields, farmers have reported that less N is required to optimize maize (Zea mays L.) yields in long term no-tillage fields than conventional tillage fields. These reductions may be attributed to improved soil health resulting from increasing soil organic matter, higher soil microbial activities, and improved water and nutrient use efficiency. However, the impact of soil health measurements on fertilizer-N requirement has not been determined. The objective of this dissertation was to compare different regional N recommendation models to measured values and develop a maize fertilizer-N recommendation model, using machine learning approaches, that includes adjustments based on …

Increasing Efficiency Of Finishing Beef Production: Strategies To Optimize Starch Digestion, Improve Flake Quality, And Reduce Methane Emissions, Ronald J. Trotta

Theses and Dissertations--Animal and Food Sciences

To continue to meet the demands of increasing food production and environmental sustainability, new strategies are needed to enhance the efficiency of finishing cattle production. A review of the literature identified several nutritional and physiological constraints that limit the ability for cattle to digest starch and absorb glucose from the small intestine. Comparative sequencing analyses revealed a missing region of the sucrase-isomaltase protein which could affect the capacity for starch digestion in cattle. Post-flaking sampling and handling recommendations were generated based on a series of experiments to improve estimates of starch availability and flaking consistency for commercial feedlots and laboratories. …

Plant Cell Wall Composition And In Vitro Fermentation Characteristics Of Cool-Season Forage Grasses From Two Growing Seasons In Central Kentucky, Sophia Danielle Newhuis

Theses and Dissertations--Animal and Food Sciences

Grass cell walls are rich in cellulose, hemicellulosic arabinoxylan (AX) polysaccharides, and lignin. AX structural differences such as degree and pattern of branching and the ester-linked phenolic acid content could affect plants’ digestibility when used as forage for livestock. However, there is little information about how these structural elements change over the growing season in the vegetative tissue of cool-season perennial grasses. Enhanced information about the cell wall composition and carbohydrate structure of forage material will provide a foundation for expanding our knowledge of how forage cell wall carbohydrate structures are utilized by ruminants. The objectives of this study were …
