Assessing The Microbiological Profile Of Raw Goat Milk And Understanding Producer Practices And Perceptions, Jacinda Skye Leopard
Theses and Dissertations
Raw milk sales are legal in 30 states, including Mississippi, where regulations are largely management-based and not food-safety related. The research objectives were to analyze the microbial profile of raw goat milk from Mississippi farms and assess food safety practices and perceptions of dairy goat farmers. Deficiencies and opportunities for improvement in raw goat milk safety were identified. Staphylococcus spp. was present in most (70%) milk samples but aligned with drying-off. E. coli, Enterobacteriaceae, and coliforms were observed in 4, 10, and 12 samples, respectively; no Salmonella spp. or Listeria monocytogenes were detected. The survey highlighted farmers' need for educational ...
Oestrogenic Subterranean Clover Guide. Identification And Remediation, 2022 Department of Primary Industries and Regional Development, Western Australia
Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd
Bulletins 4000 -
Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the ...

Wc1 And Tcr Interactions For Γδ T Cell Activation, 2022 University of Massachusetts Amherst
Wc1 And Tcr Interactions For Γδ T Cell Activation, Alexandria Gillespie
Major subpopulations of gamma delta T cells within ruminant and pigs are defined by expression of WC1, a hybrid pattern recognition receptor/co-receptor to the T cell receptor (TCR). It is known that when WC1 is knocked down cells fail to respond. Showing that WC1 plays an active role in the stimulation of bovine gamma delta T cells. Here we explored the spatio-temporal dynamics of WC1 and TCR interaction using imaging flow cytometry and stochastic optical reconstruction microscopy. We found that in quiescent gamma delta T cells both WC1 and TCR existed in separate protein domains (protein islands) but after ...

The Penn State Extension Animal Systems Team developed a toll-free hotline phone number to convey short educational messages to maintain contact and outreach to Pennsylvania’s animal producing Amish, Mennonite, and other plain Anabaptist populations. During the COVID-19 pandemic, Penn State Extension’s programming went largely online via webinars, online courses, and emails. This change in programming excluded a large sector of Pennsylvania farmers who do not use or have access to the internet and, as such, were liable to miss important best management practice reviews and timely updates in animal agriculture. The Animal Systems Hotline offered callers the choice ...
Is There Room In The United States Diet For Goat Meat? Analysis Of The 2019 National Goat Meat Survey, 2021 Missouri State University
Is There Room In The United States Diet For Goat Meat? Analysis Of The 2019 National Goat Meat Survey, Everett Marcus Martin
MSU Graduate Theses
Demand for goat meat has steadily increased in the past decade, but few studies have been conducted addressing goat meat attributes and demographic factors on consumers’ willingness to buy goat meat products. Analyzing a national consumer survey on goat meat preference, a logit modeling is used addressing factors affecting willingness to buy three goat meat products: grass-fed, locally grown, and organically raised. Results indicate that quality and freshness attribute characteristics significantly affect consumer willingness to buy grass-fed, organic, and locally grown goat meat.

Animal, Dairy, and Veterinary Science Student Research
Surgical destabilization of the stifle joint via cranial cruciate ligament desmotomy (CCLD) is a routine procedure for the study of osteoarthritis (OA). Traditionally performed in rats, rabbits, cats, and dogs, CCLD in sheep provides an opportunity to study the pathology and treatment of joint instability in a species whose stifle better represents the equivalent human femorotibial joint. The surgical approaches for CCLD in sheep are variable and can result in inconsistent outcomes. Eight sheep underwent CCLD for use in a gene therapy study. We report this case in which six of the eight sheep were clinically diagnosed by pathognomonic signs ...
The Effects Of Poor Maternal Nutrition During Gestation On Colostrum And Milk Quality And Immunoglobulin G Concentrations In Sheep, Alexandra Bettencourt
Honors Scholar Theses
Maternal over- and under-nutrition have negative effects on the growth and development of offspring. Colostrum and milk are critical to neonatal development, and composition and quality of colostrum and milk may be influenced by maternal factors, including diet. In this study, 46 pregnant ewes received one of three diets, 60% (RES), 100% (CON), or 140% (OVER) of National Research Council (NRC) nutrition requirements for total digestible nutrients from d 30 of gestation until parturition. Colostrum samples were collected within 24 hours of parturition. Milk samples were collected on d 3 and d 21 postpartum. Total solid concentrations of samples were ...

Incorporation Of Summer Annual Mixtures Into Grazing Systems In Kentucky, 2021 University of Kentucky
Incorporation Of Summer Annual Mixtures Into Grazing Systems In Kentucky, Kelly Marie Mercier
Theses and Dissertations--Plant and Soil Sciences
Utilizing summer annual grass-legume forage mixtures has the potential to improve forage yield and nutritive characteristics, and/or animal performance during times when cool-season pasture growth is limited by high temperatures. Legumes can utilize atmospheric nitrogen, which can increase crude protein and forage digestibility in mixtures. As nitrogen application generally improves both the yield and nutritive characteristics of summer annual forages, but can have a negative effect on legume competitiveness, nitrogen fertilizer recommendations for legume-containing summer annual mixtures are not well established.
Two experiments were conducted to determine the feasibility of utilizing summer annual mixtures in Kentucky, USA. The first ...
Effect Of Fecal Egg Count Estimated Breeding Value On Antibody Production In Katahdin Lambs, 2021 West Virginia University
Effect Of Fecal Egg Count Estimated Breeding Value On Antibody Production In Katahdin Lambs, Kelsey L. Bentley
Graduate Theses, Dissertations, and Problem Reports
With current pressures to seek out genetic solutions to combat antimicrobial resistance, genetic resistance to the gastrointestinal nematode Haemonchus contortus may reduce need for prophylactic antibiotic use. The Katahdin breed has effectively utilized post-weaning fecal egg count estimated breeding value (PFEC EBV) to reduce parasitism within their flocks, but there still remains significant opportunity for selection within breed. In a previous study, Katahdin sheep sired by low PFEC sires had greater survivability to weaning than lambs sired by high PFEC rams and preweaning was caused by other diseases than parasitism. Those data lead to the hypothesis that selection for PFEC ...
Classification Of Small Ruminant Lentivirus Subtype A2, Subgroups 1 And 2 Based On Whole Genome Comparisons And Complex Recombination Patterns, Aaron M. Dickey, Timothy P.L. Smith, Michael L. Clawson, Michael P. Heaton, Aspen M. Workman
Roman L. Hruska U.S. Meat Animal Research Center
Background: Small ruminant lentiviruses (SRLVs) cause a multisystemic chronic wasting disease in sheep across much of the world. SRLV subtype A2 is prevalent in North America and further classified into multiple subgroups based on variation in the group antigens gene (gag) and envelope (env) genes. In sheep, the ovine transmembrane protein 154 (TMEM154) gene is associated with SRLV susceptibility. Ewes with at least one copy of TMEM154 encoding a fulllength protein with glutamate at position 35 (E35; haplotypes 2 and 3), are highly susceptible to SRLV infection while ewes with any combination of TMEM154 haplotypes which encodes lysine (K35 ...
Evaluation Of Different Ensiling Methods On Storage And Feeding Value Of The Residual Material From Edamame Soybean Processing, 2020 University of Arkansas, Fayetteville
Evaluation Of Different Ensiling Methods On Storage And Feeding Value Of The Residual Material From Edamame Soybean Processing, Ellen Herring
Graduate Theses and Dissertations
Use of organic waste material by ruminant animals from food processing operations potentially reduces costs and reduces environmental issues from disposal of these residues. Therefore, 2 experiments were conducted to evaluate the storage and feeding value of residual from edamame soybean processing for ruminant animals. Two types of waste streams, waste during harvest time and waste from processing stored material, were ensiled (on a laboratory scale) using various methods and effects on post-ensiling nutritive value were examined. Material from both waste streams were ensiled either without wilting or after wilting; each moisture level was ensiled with and without an inoculant ...

Prospects For Enhancing The Market For Goat Meat Products: Analysis Of The 2019 Goat Meat Survey, Ashton M. Light
MSU Graduate Theses
The objective of this study was to identify goat meat product attributes and sociodemographic drivers of consumers’ willingness to buy to goat meat products. To do so the study used a nationwide consumer survey on goat meat preferences. A binary logit model was used to examine the factors affecting willingness to buy. Results show that gender, age, region, primary shopper, and product attribute preference for quality, price, leanness, cholesterol, and freshness significantly affect consumer willingness to buy goat sausage, jerky, burger, and patties.
Livestock Preference For Endophyte-Infected Or Endophyte-Free Oxytropis Sericea, Ipomoea Carnea, And Ipomoea Asarifolia, James Pfister, Daniel Cook, Stephen T. Lee, Dale R. Gardner, Franklin Riet-Correa
Poisonous Plant Research (PPR)
Fungal endophyte-infected forages have been shown to alter herbivore feeding preferences. The objective of this experiment was to compare the preference of cattle, sheep, and goats for plants containing (E+) and not containing (E-) fungal endophytes using freshly harvested Oxytropis sericea, Ipomoea carnea, and Ipomoea asarifolia. Goats and sheep rejected all forage choices regardless of endophyte status except for grass and alfalfa hay. Endophyte status had no influence on cattle forage preferences. Cattle rejected all Oxytropis sericea E+ and E- choices. Cattle discriminated between Ipomoea species, preferring Ipomoea carnea to Ipomoea asarifolia (P = 0.004). In all comparisons, Ipomoea carnea ...

Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones
Animal Science Undergraduate Honors Theses
Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and ...

Graduate Theses and Dissertations
Forage-based ruminant diets supplemented with condensed tannins or polyphenolic-containing legumes may alter nitrogen (N) metabolism in the animal and reduce gas emissions from soil receiving excreta. The objective of the study was to determine if soil receiving urine or manure from sheep fed forage diets supplemented with condensed tannin or polyphenolic-containing legumes would decrease N gas emissions. Two field trials were conducted: in the first trial, sheep were fed alfalfa (Medicago sativa L.) silage diets supplemented with 0, 9, 18, or 27% sericea lespedeza (Lespedeza cuneate [Dumont de Courset] G. Don) (n = 4). In the second trial sheep were fed ...
