In the last decade livestock-associated methicillin-resistant S. aureus (LA-MRSA) has become a public health concern in many parts of the world. Sequence type 398 (ST398) has been the most commonly reported type of LA-MRSA. While many studies have focused on long-term exposure experienced by swine workers, this study focuses on short-term exposures(More)
The objective of this study was to quantify pain sensitivity differences using mechanical nociception threshold (MNT) and thermal nociception threshold (TNT) tests when sows were in painful and nonpainful transient lameness phases. A total of 24 mixed parity crossbred sows (220.15 ± 21.23 kg) were utilized for the MNT test, and a total of 12 sows (211.41 ±(More)
BACKGROUND The purpose of this study was to determine intravenous (IV), intramuscular (IM) and oral (PO) FM PK in mature swine. Appropriate pain management for lameness in swine is a critical control point for veterinarians and producers, but science-based guidance on optimal housing, management and treatment of lameness is deficient. Six mature swine(More)
To investigate a novel route for providing analgesia to processed piglets via transmammary drug delivery, meloxicam was administered orally to sows after farrowing. The objectives of the study were to demonstrate meloxicam transfer from sows to piglets via milk and to describe the analgesic effects in piglets after processing through assessment of pain(More)
Objective: To provide diagnostic and veterinary support to niche producers in order to generate information on disease pressures in niche herds. Materials and methods: Twenty-six producers under contract with three niche-marketing companies were accepted into the program. A standardized diagnostic protocol, including serology and tissue diagnostics, was(More)
Transmammary-delivered meloxicam in piglets undergoing castration and tail docking: impact on pharmacokinetics and pain biomarkers" (2015). Graduate Theses and Dissertations. Paper 14754. DEDICATION This thesis is dedicated to my parents, Kent and Marla Bates. Without their unwavering support, guidance, and encouragement towards education, I wouldn't be the(More)
Objective: To determine how quickly all pigs visited the nipple cup drinker, the number and duration of visits, and water disappearance when water was restored after a 15-hour withholding period. Materials and methods: A total of 184 seven-week-old pigs, identified with unique numbers, were commercially housed (23 pigs per pen), with one stainless steel(More)
Objectives: To determine stability of ace-tylsalicylic acid (ASA) and sodium salicy-late (SS) stock solutions, and to determine plasma concentrations of SS in swine after administration in drinking water. Materials and methods: Stock solutions of liquid ASA and SS products were placed in a nursery environment for 24 hours (Trial One). Salicylate(More)
Objective: To assess the diagnostic accuracy of two minimally invasive methods of blood collection and a reference method. Materials and methods: Blood samples were collected from 30 pigs at 7 and 8 weeks of age. Fifteen pigs were then inocu-lated with porcine reproductive and respiratory syndrome virus (PRRSV) VR-2332 and 15 remained uninoculated. Pigs(More)
