Characterizing Environmental Background Microflora And Assessing Their Influence On Listeria Persistence In Dairy Processing Environment, Vaishali Poswal, Sanjeev Anand, Brian Kraus

Dairy Science and Food Science Faculty Publications: 2022 to Present

Listeria monocytogenes (Lm) may persist in food processing environments (FPEs) alongside diverse background microflora. While microbial communities in FPEs can in- fluence Lm survival, their role in supporting or suppressing its growth remains unclear. This study aimed to characterize the microflora in floor swabs and air samples collected from a dairy processing facility across three seasons and assess their potential impact on the growth of a Lm test strain previously isolated from a dairy processing environment. A total of 167 environmental isolates, representing 30 bacterial genera, were identified. Pseudomonas was consistently prevalent across all sample types. Seasonal shifts in bacterial …

Impact Of Polysaccharides On Advancing Plant-Based Meat Alternatives, Prashant Dahal, Clifford Hall, Srinivas Janaswamy

Dairy Science and Food Science Faculty Publications: 2022 to Present

Plant-based meat products are a valued choice for vegetarians and others. Their production has been perceived as an innovation promoting animal welfare and sustainability. However, there are challenges in simulating desirable appearance, texture, and flavor using only plant-based protein sources. Polysaccharide addition during the formulation and texturization of plant proteins can improve the physi- cochemical and sensory properties of texturized protein products. In this regard, a clear understanding of the fundamental properties of polysaccharides is essential for transforming plant proteins into fibers or nonfilamentous protein aggregates. Enhancing water-holding capacity, gelation, and binding functionality is crucial for overcoming structural and textural …

Cooperative Extension Service Records, Sdsu Archives And Special Collections, Hilton M. Briggs Library

University Archives

The Smith-Lever Act of 1914 established a national agricultural extension system, which was implemented at South Dakota State College, building on earlier efforts like Farmers' Institutes. Over time, the service expanded to provide personalized assistance to farmers, youth programs like 4-H, and specialized technical expertise in various agricultural fields.

This collection documents the Cooperative Extension Service's work in South Dakota, including Administrative Records, such as annual reports, impact statements, and the service's history and philosophy. It features 4-H Publications, including guides and historical materials, as well as Personnel Communications distributed to Extension staff. News Releases cover outreach efforts from 1939 …

Potential Of Anogenital Distance As A Genetic Selection Trait In Canadian Holstein, G.R. Dodd, F.S. Schenkel, F. Miglior, T.C. Bruinjé, M. Gobikrushanth, J.E. Carrelli, M. Oba, D.J. Ambrose, C.F. Baes

Dairy Science and Food Science Faculty Publications: 2022 to Present

Maintaining optimal fertility in dairy cattle herds is a global challenge that is typically addressed through the genetic selection of fertility indicator traits. However, many of the traits currently implemented in breeding programs are heavily influenced by environmental factors, resulting in a slow rate of genetic improvement. Anogenital distance (AGD) has recently emerged as a promising fertility indicator trait due to its association with favorable reproductive outcomes and its higher heritability estimates compared with currently evaluated traits. This study aimed to enhance the understanding of AGD's genetic potential by estimating its genetic parameters in Canadian Holsteins, assessing the reliability …

Integrating Invasion Risk And Habitat Suitability To Guide Invasive Species Management In Wetlands, Lakes, And Rivers, Brenden M. Elwer

Electronic Theses and Dissertations

Invasive species disrupt ecosystems by altering habitats, competing with native species, and disrupting food webs. The northern Great Plains is an ecologically important region with many wetlands, lakes, and rivers that are under threat from two invasive species, Bighead (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix; bigheaded carp). These large planktivores change the abundance and composition of phytoplankton and zooplankton communities which alters prey for native mussels, fishes, and, potentially, waterfowl. Bigheaded carps have invaded a portion of the Northern Great Plains, and preventing further spread is a primary management goal. My work assists these efforts by providing tools to …

Effects Of Storage Conditions On The Composition, Physical Properties, And Functionalities Of Peas And Lentils, Fatimah Alsaeed

Electronic Theses and Dissertations

Peas (Pisum sativum L.) and lentils (Lens culinaris) are nutritionally rich pulses valued for their high protein, fiber, and starch content. Although their composition and health advantages are widely known, little is known about the effects of long-term storage on their functional qualities and nutritional value. The purpose of this study was to investigate the impact of storage conditions and duration on the proximate composition, physical attributes, and techno-functional traits of lentils and peas. Storage conditions included bin (BIN; -30 to 41°C, 20–98% RH), non-environmentally controlled warehouse (NECW; -23 to 32°C, 25–84% RH), and environmentally controlled warehouse (ECW; 19–21°C, 50–53% …

Assessment And Management Of Dectes Stem Borer, Dectes Texanus Leconte, In South Dakota Soybeans, Zachary Loomis

Electronic Theses and Dissertations

The Dectes stem borer (Dectes texanus LeConte, Coleoptera: Cerambycidae) has emerged as an increasingly significant pest of soybean (Glycine max) in South Dakota. Although historically considered a minor concern, rising populations of this insect have led to significant preharvest lodging and subsequent yield loss in affected fields. The Dectes stem borer's larval feeding within the soybean stem interferes with nutrient flow, and as the season progresses, this internal feeding weakens stem integrity, amplifying lodging risks and causing considerable challenges for farmers and researchers. Since 2017, both the number and severity of Dectes stem borer infestations have been on the rise …
