Evaluation Of Boron Supplementation In Swine And Poultry, Tyler B. Chevalier Jan 2023

Evaluation Of Boron Supplementation In Swine And Poultry, Tyler B. Chevalier

Theses and Dissertations--Animal and Food Sciences

The objectives of this dissertation were to evaluate dietary boron (B) supplementation as sodium borate in various swine models and broiler chicks through a series of experiments. The initial experiment evaluated supplemental B (0, 25, 50, and 100 ppm B) on serum insulin, glucose, and clinical chemistry panel of growing pigs. Serum insulin/glucose ratio tended to decrease linearly with increasing supplemental B in a fasting state (P = 0.08). These findings were more noticeable (linear effect, P = 0.02) in a postprandial state (~ 50 minutes following a meal). A series of follow-up studies further evaluating B supplementation (0, 5, …

Transitioning To Net Energy: A Swine Story, John F. Patience Sep 2022

Transitioning To Net Energy: A Swine Story, John F. Patience

Proceedings of the Arkansas Nutrition Conference

Net energy (NE) is one member of the sequence of energy systems which also includes gross energy (GE), digestible energy (DE), and metabolizable energy (ME). It is perhaps the most sophisticated because it attempts to consider more components of the ingredient or diet which normally cannot be used by the pig for maintenance and/or productive purposes. Gross energy makes no such adjustment and therefore has little direct value in diet formulation. Digestible energy corrects for energy which is lost in the feces, and metabolizable energy also adjusts for energy lost in the urine. The data in Table …

Genomic Organization And Expression Of The Wc1 Hybrid Coreceptor And Pattern Recognition Receptor On Porcine Gamma Delta T Cells, Lauren Le Page Mar 2022

Genomic Organization And Expression Of The Wc1 Hybrid Coreceptor And Pattern Recognition Receptor On Porcine Gamma Delta T Cells, Lauren Le Page

Doctoral Dissertations

gd T cells are a crucial component of the immune response to a number of increasingly relevant and largely zoonotic pathogens to which efficacious vaccination is lacking. In ruminants and swine, gd T cells represent a major population of peripheral blood and epithelial tissue-resident lymphocytes. gdT cells respond to both protein and non-protein antigens independently of MHC presentation and possess immunological memory. Upon activation, gamma delta T cells illicit a variety of effector functions and play an indispensable role of orchestrating the downstream immune response. These characteristics make gamma delta T cells a promising candidate for recruitment by vaccination, however, …

Development Of A Self-Emulsifying Adjuvant For Use In Swine Vaccines, Rachel Madera, Yulia Burakova, Lihua Wang, Jishu Shi

Kansas Agricultural Experiment Station Research Reports

Emulsion-based adjuvants are commonly used in animal vaccine formulations for several reasons including affordability, stability, and efficacy in inducing disease-protecting immune responses. Here we report a novel, cost-effective, stable, self-emulsifying adjuvant (SEA1) that is prepared by a simple low shear process or low-energy mixing without the use of expensive and complex proprietary equipment. Characterization of the SEA1 adjuvant showed good stability at different temperatures (4°C, 20°C, and 37°C) after one month of storage. Minimal changes in droplet size distribution, polydispersity index, Zeta potential and pH in 1-month-old SEA1 preparations were observed when compared with a fresh SEA1 preparation. SEA1 emulsion-based …

Breed Differences In Placental Development During Late Gestation Between Chinese Meishan And White Crossbred Gilts In Response To Intrauterine Crowding, Jeremy R. Miles, Jeffrey L. Vallet Mar 2021

Breed Differences In Placental Development During Late Gestation Between Chinese Meishan And White Crossbred Gilts In Response To Intrauterine Crowding, Jeremy R. Miles, Jeffrey L. Vallet

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The objective of this study was to evaluate placental development during late gestation (day 100) between Chinese Meishan (CM; n = 7) and White crossbred (WC; n = 5) gilts following intrauterine crowding induced by unilaterally hysterectomy-ovariectomy. Gross placental morphology and areolae density as well as histological morphology (i.e., folded bilayer and placental stroma) were analyzed using computer-assisted morphometry for placentas of the smallest and largest fetuses within each litter. There was a breed by fetal size interaction (P < 0.01) for areolae density in which placentas for large CM fetuses had greater areolae density compared to small CM fetuses, but the density of areolae was greater for CM fetuses compared to WC fetuses, irrespective of fetal size. The width of the folded bilayer was greater (P < 0.01) in placentas for WC gilts compared to CM gilts, irrespective of fetal size. Placentas for small fetuses had greater (P < 0.01) folded bilayer width compared to large fetuses, irrespective of breed. The placental stromal width was greater (P < 0.01) in placentas for large fetuses compared to small, irrespective of breed. The difference between stromal width in placentas between divergent-sized littermates, however, was greater (P = 0.05) in WC gilts compared to CM gilts, indicating there was a limited response to intrauterine crowding in CM gilts. These results indicate there is an altered placental development during late gestation in CM compared to WC gilts, thus, there are likely different mechanisms for responding to intrauterine crowding between breeds.

BACKGROUND: Lethal removal of invasive species, such as wild pigs (Sus scrofa), is often the most efficient approach for reducing their negative impacts. Wild pigs are one of the most widespread and destructive invasive mammals in the USA. Lethal management techniques are a key approach for wild pigs and can alter wild pig spatial behavior, but it is unclear how wild pigs respond to the most common removal technique, trapping.We investigated the spatial behavior of wild pigs following intensive removal of conspecifics via trapping at three sites within the Savannah River Site, SC, USA. We evaluated changes in …

A Framework For Surveillance Of Emerging Pathogens At The Human-Animal Interface: Pigs And Coronaviruses As A Case Study, Kim M. Pepin, Ryan S. Miller, Mark Q. Wilber

USDA Wildlife Services: Staff Publications

Pigs (Sus scrofa) may be important surveillance targets for risk assessment and risk-based control planning against emerging zoonoses. Pigs have high contact rates with humans and other animals, transmit similar pathogens as humans including CoVs, and serve as reservoirs and intermediate hosts for notable human pandemics. Wild and domestic pigs both interface with humans and each other but have unique ecologies that demand different surveillance strategies. Three fundamental questions shape any surveillance program: where, when, and how can surveillance be conducted to optimize the surveillance objective? Using theory of mechanisms of zoonotic spillover and data on risk factors, …

The Effect Of Triptorelin On Ovulation Rate And Conception Rate In Gilts And The Endocrine Profile In Non-Pregnant And Early Pregnant Gilts, Joseph Wollbrink

Electronic Theses and Dissertations

Triptorelin is a gonadotropin releasing hormone agonist that has been shown to be effective in weaned sow single fixed time artificial insemination protocols. Administration of triptorelin 96 h after weaning has been shown to be effective in synchronizing sows to be inseminated one time 24 h later without reducing pregnancy rate or the number of pigs born. In the current experiment, 23 crossbred gilts (249 d, 123 kg) were administered an intramuscular injection of PG600. Nine days after PG600 administration, gilts were fed 15 mg of altrenogest once daily for 16 d. Twelve gilts (OVU) were administered 200 μg triptorelin …
