Turkish Journal of Veterinary & Animal Sciences

The phylum Acanthocephala contains approximately 1300 acanthocephalan species. So far, only nine acanthocephalan species of wild birds have been reported in Türkiye. To study the context of acanthocephalan diversity in wild birds in Türkiye, we examined 193 birds from 69 species belonging to 16 orders. Acanthocephalans were found in seven bird species: Centrorhynchus aluconis in Buteo buteo and Buteo rufinus, Centrorhynchus spinosus in Buteo buteo and Strix aluco, Mediorhynchus papillosus in Iduna icterina, Mediorhynchus tenuis in Luscinia svecica, Plagiorhynchus cylindraceus in Erithacus rubecula and Turdus merula, Polymorphus contortus in Anas platyrhynchos, and Sphaerirostris turdi in Turdus merula. Except for Plagiorhynchus …

Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami

All Theses

Globally, cardiovascular diseases, in most cases associated with calcification, are the main cause of death. However, currently, the only effective cure is to undergo surgery to augment or receive a healthy donor heart, which could be very difficult due to the long waiting list and the associated risks. The possibility of body rejection of the foreign organs is attributed to immunoreaction or the risk of infection, since the donor must be on immunosuppressant drugs that lower the body's immunity and facilitate the body's acceptance of the new organ as one of its own. Taking that into consideration, using tissue-engineered vascular …

The Effect Of Diet Formulations Containing Different Protein Sources On Energy And Nitrogen Utilization In Lactating Jersey Cows, Kortney Ann Harpestad

Department of Animal Science: Dissertations, Theses, and Student Research

It is well understood that lactating dairy cows require metabolizable protein (MP) for milk yield and milk protein synthesis. Diets with conventional feed sources like corn and soybean meal (SBM) may not sufficiently meet all MP and amino acid (AA) requirements so supplementation with more rumen undegradable protein (RUP) rich feeds or rumen-protected AA can be fed to support animal performance. The growth trajectory of biofuels has resulted in dramatic increases in the production of feeds like heat treated soybean meal (HTSBM). While the chemical composition of this product is understood, there is a need to better understand how HTSBM …

Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn

LSU Master's Theses

While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …

Overcoming Maternal Antibody Interference In Swine Influenza: Advancing Dna Vaccine Strateies For Enhanced Immune Protection In Piglets, Danh Cong Lai

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Maternally derived antibodies (MDAs) play a vital role in protecting neonates from infectious diseases, but their presence at the time of vaccination can interfere with vaccine-induced immune responses, thereby reducing vaccine effectiveness. MDA interference has been documented in pigs vaccinated with whole inactivated virus (WIV) vaccines against swine influenza A virus (IAV). In this thesis, we evaluated the efficacy of a lipid nanoparticle encapsulated DNA (LNP-DNA) vaccine against swine IAV in the presence and absence of MDAs, comparing it to a WIV vaccine. In MDA-negative piglets, both the LNP-DNA and WIV vaccines induced strong immune responses and effectively prevented the …

Dietary Organic Selenium Supplementation Improved Some Gross Morphological Parameters And Biochemical Characteristics Of Testes In Young Male Kids, Nadia Rahim, Moolchand Malhi, Asma Babar, Muhammad Awais Soomro, Shazia Rahim

Journal of Bioresource Management

Selenium (Se) plays a vital role in improving reproductive health in ruminants. This study evaluated the impact of Se supplementation on testicular health in young male goats. Twenty goats (2–3 months old, 8.5–10 kg) were randomly assigned to two groups: Control (C, n=10) receiving a basal diet (0.037 mg Se/kg) and Se-Yeast (SY, n=10) supplemented with 0.3 mg Se/kg diet. The trial lasted eight weeks. Results showed that testis weight was significantly higher in the SY group (26.8 ± 2.5 g) compared to C (22.4 ± 2.1 g, p < 0.05). Testis length, width, and circumference also increased significantly in SY goats (4.5 ± 0.3 cm, 2.9 ± 0.2 cm, and 7.4 ± 0.4 cm, respectively) compared to control (3.9 ± 0.4 cm, 2.5 ± 0.3 cm, and 6.7 ± 0.5 cm; p < 0.05). Serum cholesterol was higher in SY (135.27 ± 2.34 mg/dl) than in C (121.15 ± 8.74 mg/dl, p = 0.02), while triglycerides were lower (95.99 ± 1.37 vs. 114.38 ± 1.84 mg/dl, p = 0.0003). HDL increased (51.97 ± 2.10 vs. 45.02 ± 1.32 mg/dl, p = 0.03), and LDL decreased (54.23 ± 1.81 vs. 61.27 ± 1.56 mg/dl, p = 0.02) in SY group. Total serum protein rose significantly (8.14 ± 0.79 vs. 5.25 ± 0.06 mg/dl, p = 0.03), as did testosterone levels (1.95 ± 0.08 vs. 1.43 ± 0.06 ng/ml, p = 0.002). In conclusion, selenium supplementation significantly improved testicular morphology, lipid profile, protein levels, and testosterone, indicating enhanced reproductive health in goats.

Stereotypic Behaviors And Physiological Indicators Of Stress Occur In Horses With Restricted Durations Of Turnout, Elizabeth E. Rodgers

Department of Animal Science: Dissertations, Theses, and Student Research

The confinement of horses to stalls with limited or no turnout time restricts their natural roaming behaviors, which potentially increases stress and behavioral stereotypies. This study investigated the impact of turnout duration on behavioral and physiological stress indicators in healthy horses. Adult horses (n = 11) were enrolled in a 3 treatment (0-, 15-, and 60-minute turnout/day) Latin square design, including 3 12 d experimental periods over 6 weeks. Horses were acclimated to turnout (24.38 x 64.01m indoor arena) and stalls (2.74 x 4.87m - 3.66 x 3.66m) stalls prior to data collection on day 1. Experienced handlers managed …

Digestibility, Palatability, And Nutrient Composition Of Three Species Of Whole Prey In Three Species Of Snakes, Morgan R. Kienzle

Department of Animal Science: Dissertations, Theses, and Student Research

Snakes in human care often lack diversity in the diet. Rodents account for the majority of meals, while wild snakes are consuming a varied diet composed of multiple different whole prey species. By feeding only one species of prey, the chance of nutrient deficiencies and other health concerns increases. To promote variety in the managed diet, two commercially available whole prey species (mice (Mus musculus) and chicks (Gallus spp.)) and one novel species (Seba’s short-tailed bats (Carollia perspicillata)), were analyzed for their dry matter (DM), organic matter (OM), crude protein (CP), crude fat …

Both BCA and corn oil were added to the base diet as a top dress. Results from this study did not show any …

Gonadotropin-Releasing Hormone Ii And Its Receptor: Novel Regulators Of Semen Quality And Follicular Function In Swine, Caitlin Elizabeth Ross

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Pigs are the only mammalian livestock species encoding functional proteins for the second form of gonadotropin-releasing hormone (GnRH-II) and its receptor (GnRHR-II). In the first study, GnRHR-II localized to developing germ cells and the connecting piece of ejaculated spermatozoa. Concurrently, GnRH-II was most abundantly produced in the testis compared with other reproductive tract organs and was present within seminal plasma. Moreover, treatment of extended semen with GnRHR-II analogues altered sperm motility, morphology, and kinematics. For remaining studies, we utilized a swine line with ubiquitous knockdown of GnRHR-II (GnRHR-II KD) developed in our laboratory. The second study demonstrated that circulating GnRH-II …

Data From: The Dynamic Responses Of The Mouse Gut Microbiome To Dietary Supplementation With Various Anthocyanin-Rich Foods In The Context Of A Western Diet, Abby D. Benninghoff

Browse all Datasets

Background/Objectives: Anthocyanin (ACN)-rich foods may support gut health by modulating the microbiome and reducing inflammation, potentially lowering the risk of colitis-associated colorectal cancer. However, the dynamic response of the gut microbiome to ACN-rich diets is not well characterized, including in the context of structural and compositional differences among ACN-containing foods. This study examined the temporal response of the mouse gut microbiome to dietary ACNs, focusing on the impact of structural variation. We hypothesized that microbiome shifts would occur rapidly but require sustained dietary ACN intake to persist. Methods: C57BL/6J mice were fed the total Western diet (TWD) supplemented with freeze-dried …

The Design, Construction, And Testing Of Mrna Vaccine Against Equine Herpes Virus, Bhawana Devkota

LSU Master's Theses

Equine Herpesvirus-1 (EHV 1) is a worldwide significant pathogen that causes respiratory illness, abortion, and neurological disorders in equine. Current vaccines, including live attenuated, inactivated, and subunit platforms, do not prevent viral latency, mucosal shedding, or cross-strain immunity, requiring alternative approaches. To address these gaps, this project explores the design, synthesis, and in vitro testing of an mRNA vaccine targeting immunogenic EHV 1 glycoprotein (gB, gC, gD, gG, and gM). Epitopes were computationally predicted using the Immune Epitope Database (IEDB), codon-optimized for Bos taurus, and cloned into pUCIDT vectors using SP6/T7 promoters. In vitro transcription (IVT) used nucleotide modifications …

Karbala International Journal of Modern Science

The viral disease affects the whiteleg shrimp (Litopenaeus vannamei) and causes losses. Immunostimulants are recognized as a more environmentally friendly approach to disease management and antimicrobial properties of aquatic organisms. Watercress (Nasturtium officinale) is an aquatic plant species that contains antioxidant properties that can protect the organism from disease and boost the immune system. Shrimp rely heavily on innate immunity to combat infectious agents due to their absence of adaptive immunity. Peroxinectin and scavenger receptor class B (SRB) play essential roles in the shrimp defense system. This research employs a bioinformatic to assess the immunostimulatory potential …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston

Nebraska Beef Cattle Reports

This study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Heifers were artificially inseminated with semen from one of three single-sires or semen from a combination of the same three sires. Pregnancy rates did not significantly differ. Paternity testing suggests sire parentage can be unequal when semen is mixed from multiple sires. In summary, producers can expect similar pregnancy rates using single-sire and multi-sire semen, but progeny may have unequal sire representation.

Impact Of Overwinter Gain On Growth And Reproductive Performance In March-Born Heifers, Josie N. Crouch, J. Travis Mulliniks, Jacki A. Musgrave, Kacie L. Mccarthy

Nebraska Beef Cattle Reports

Summary with Implications

Heifers developed to lower rates of overwinter gain may reduce development costs without growth and reproduction impacted. A 3-year study was conducted to evaluate different overwinter rates of gain on heifer growth rates, reproductive, and economic performance. Heifers were managed together and individually supplemented (January-May) with dried distillers grains to achieve either a low (0.75 lb/d) or high (1.50 lb/d) average daily gain. At breeding, high gain heifers were heavier than low gain heifers. Average daily gain and body condition score were similar between treatments. Overwinter treatment did not impact attainment of puberty, pregnancy rates, or the …
