The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, Crystal Collier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans rely on the health of their joints for stability and mobility in daily life. In a normal, healthy functioning joint, complex processes maintain joint tissues, including remodeling, lubrication, and immune function among many other tasks. Osteoarthritis (OA) is the most common joint disorder in the U.S. It becomes most prevalent in adults 60+ years of age and causes decreased mobility, discomfort, and in some cases, excruciating pain. In the biological processes of osteoarthritis, the metalloproteinase enzymes responsible for the degeneration of cartilage are upregulated. The inhibitors of metalloproteinase activity are known as Tissue Inhibitor of Metalloproteinases (TIMPs), which keep …

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 …

Effect Of Selected Tanniniferous Leaves On In Vivo Enteric Methane Emission In Sheep, M. Saravanan, R. Bhatta, L. Baruah, P. K. Malik, N. Ravi

IGC Proceedings (1997-2023)

Concentration of methane is continuously increasing in atmosphere and now almost 155% (IPCC, 2007) more than that recorded during pre-industrial era. Livestock production is a major sector accountable for high methane emission into atmospheric pool. World’s livestock is contributing around 15% of total atmospheric methane on annual basis feeds (Moss et al., 2000). Additionally, methane emission from ruminants leads to a loss of 2 to 15% of the dietary energy (Holter and Young, 1992). Due to these two crucial issues, researchers are working tirelessly to find a suitable and effective way for enteric methane amelioration accompanied with minimal inputs. …

We conducted a cross-sectional survey of Crimean-Congo hemorrhagic fever virus (CCHFV) in dromedary camels and attached ticks at 3 locations in the United Arab Emirates. Results revealed a high prevalence of CCHFV-reactive antibodies in camels and viral RNA in ticks and camel serum, suggesting the virus is endemic in this country.

Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones

Animal Science Undergraduate Honors Theses

Abstract

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 …

Quantifying Greenhouse Gas Emissions And Ammonia Volatilization From Soil Amended With Excreta From Ruminants Fed Alternative Forage-Based Diets, Samuel Park

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 …

The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba

IGC Proceedings (1997-2023)

Pastoralist groups in India, including the Raika of Rajasthan, Pullikulum cattle breeders in Tamil Nadu, and groups such as the Dhangar, Kuruba and Kuruma of the Deccan Plateau realize a major proportion of their income from penning their herds and flocks on farmers’ fields. Focusing on shepherds from Northern Karnataka, this paper makes a first attempt at calculating the impact of penning on livelihoods, soil fertility and the national economy.

Poor Maternal Nutrition During Gestation Alters Placental Igf-I, Igf-Ii, And Igfbp-3 Mrna Expression In Sheep, Caitlyn Splaine

Honors Scholar Theses

Insulin-like growth factors (IGF) modulate placental and fetal growth and development through nutrient sensing and endocrine signaling. We hypothesized that poor maternal nutrition during gestation would alter IGF-I, IGF binding protein (IGFBP)-2, and IGFBP-3 mRNA expression in the ovine placenta, but would not affect IGF-II mRNA expression. Pregnant ewes (n=57) were individually fed: 60% (restricted fed; RES), 100% (control fed; CON), or 140% (over fed; OVER) of National Research Council requirements for TDN starting at day 30±0.2 of gestation. Ewes were euthanized and cotyledon and caruncle samples were collected at days 45, 90, and 135 of gestation. Relative mRNA expression …

Policy Measures For Extensive Farming Systems In Southwest Norway, Lief Jarle Asheim, Pål Thorvaldsen, Odd J. Øvreås

IGC Proceedings (1997-2023)

The open landscapes produced over centuries by farming in southwest Norway are threatened by agricultural abandonment, raising public concern for maintenance of the species rich and valuable coastal grasslands. A study in two municipalities revealed that semi-natural grasslands, traditionally grazed in spring and fall and mowed in-between, are most affected. Two linear programming models, one for part time sheep farms and one for larger mixed dairy and meat farms, were developed to study measures for stimulating production, in particular effects on grazing and land utilization of altering support between leys, farm pasture, and grazing animals. Yields and fertilization level in …

Economic Trade-Offs Of Novel Forage Use In Livestock Production Systems: Insights From Australia, Marta Monjardino, Neil D. Macleod, Dean K. Revell

IGC Proceedings (1997-2023)

Globally, livestock are a major component of agricultural systems and natural resource management, as well as an important contributor to nutrition and livelihoods, but are often undervalued (Herrero et al., 2009). In Australia, livestock production systems occupy half of the available land and contribute to ~50% of gross agricultural production. The main livestock systems are beef cattle grazing at low intensity in the arid and semi-arid regions of northern and central Australia; and sheep flocks integrated in crop-livestock systems in the temperate zone of southern Australia (Bell et al., 2014). Despite increased physical productivity (changes in outputs relative …

Ethical Use Of Cereal Legume Intercrop Forages For Feeding Of Sheep And Pasture Development, S. B. Maity, K. K. Singh, G. Prabhu, N. Das

IGC Proceedings (1997-2023)

Cereal forages are important in the feeding of livestock for their high energy and dry matter content. However, they are low in protein content and inferior in other nutritional quality than the legume forages. Ruminants required protein as well as energy to maintain their production. Supplementation of protein through concentrates is cost effective in livestock production. Besides, ruminant is unique in having the potential for cycling forage materials, poor quality protein and non protein nitrogen sources into human food supply as meat and milk (Eskandary et al., 2009). Thus, management of forages for livestock feeding either in feedlot or in …

Plant And Animal Responses To Different Grazing Regimes On A Meadow Steppe In Northeast China, Deli Wang, Zhiming Yang, Ling Wang

IGC Proceedings (1997-2023)

Grazing by domestic herbivores is often considered to be an essential factor governing grassland vegetation and animal production (Hodgson and Illius 1996). During recent decades, there is increasing interest as a fundamental interaction between plant-animal interface, especially for the simultaneous or interactive responses of plants and animals to grassland grazing regimes (Liu et al., 2015), which benefits on improving the efficiency of grazing or grassland resource management. To achieve sustainable animal productivity and maintain the stability of grasslands, farmers or stakeholders need to employ optimal grazing strategies or regimes based on practical grassland vegetation and environments. Unfortunately, up to date …

Effect Of Mineral Supplementation On Rumen Metabolites And Enzymes In Sheep Fed Sorghum Stover Based Diets, Shweta Singh, S. K. Mahanta, Rishi Saxena

IGC Proceedings (1997-2023)

Supplementation of area specific mineral mixture (ASMM) containing Ca, P, Na, Cu, and Zn to producing animals showed noticeable improvement in growth, milk production and reproductive performances. However, there was paucity of information on rumen metabolites and enzymes in animals supplemented with ASMM. Therefore, the present investigation was conducted to study the effect of mineral supplementation (ASMM) on rumen metabolites and enzymes in sheep fed sorghum stover based diets.

Sequential Analysis Of Livestock Herding Dog And Sheep Interactions, Jonathan Early, Jessica Alders, Elizabeth R. Arnott, Claire M. Wade, Paul Mcgreevy

Interactive Behavior Collection

Livestock herding dogs are crucial contributors to Australian agriculture. However, there is a dearth of empirical studies of the behavioural interactions between dog and livestock during herding. A statistical approach that may reveal cause and effect in such interactions is lag sequential analysis. Using 48 video recordings of livestock herding dogs and sheep in a yard trial competition, event-based (time between behaviours is irrelevant) and time-based (time between behaviours is defined) lag sequential analyses identified several significant behavioural interactions (adjusted residuals greater than 2.58; the maximum likelihood-ratio chi-squared statistic for all eight contingency tables identified all sequences as highly significant …
