Most models of protein evolution are based upon proteins that form relatively rigid 3D structures. A significant fraction proteins, the so-called disordered do not structures and sample a broad conformational ensemble. Disordered typically maintain long-range interactions, so constraints on their should be different than ordered proteins. To test this hypothesis, we developed compared for Substitution matrices were constructed using sequences putative homologs sets experimentally...
Abstract 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 swine is a critical control point veterinarians producers, but science-based guidance on optimal housing, treatment deficient. Six (121–168 kg) were administered an IV, IM, or PO dose flunixin meglumine at target 2.2 mg/kg cross-over design with 10 day washout period between treatments. Plasma samples collected up 48...
Two hundred steers and heifers from a large feedyard (65,000-head capacity) were used to determine the prevalence levels of enterohemorrhagic Escherichia coli O157 (EHEC O157) Salmonella spp. prior after shipping commercial packing facility. samples, ventral midline hide swab fecal sample, aseptically collected each animal 2 weeks date transportation at plant immediately exsanguination. Samples all trailers (n = 46) before animals loaded for transport The average EHEC on hides (18%) in feces...
Two hundred eighty-seven lactating Newsham sows and their litters were used to determine the effects of intensive indoor (n = 147) outdoor 140) production systems on sow litter productivity behavior. All contemporary age fed a completely balanced sorghum-based diet. Behavior data collected by live observation 40 (20 20 outdoor) using 5-min scan sample over 4-h period in afternoon (1400 1800). The durations lying (90.0 vs 72.1 +/- 2.76% time observed) drinking (4.42 1.41 0.6% higher (P <...
The objective of this review was two-fold. First, a series meta-analyses (analyses treatment effects across studies) were performed on available data from scientific literature to determine whether sow behavior, performance, or physiology differed for sows in group pens individual stalls. Second, research publications areas performance and health, physiology, behavior pregnant gilts studies that directly compared gestation housing systems summarized. Common stalls, tethers, various types...
The objective of this study was to identify environmental and management factors that are associated with the frequency fatigued, injured, dead pigs on arrival in resting pens during lairage at a commercial Midwest abattoir. terms transport losses or total refer die become nonambulatory any stage marketing process. In study, were summed into variable termed losses. Relative humidity (%), temperature ( degrees C), wind speed (m/s), dew point C) data collected 12,333 trailer loads pigs. Week,...
Few issues in swine production are as complex floor space allowances. One method for pork producers to calculate allowance (A) is convert BW into a 2-dimensional concept yielding an expression of A = k * BW0.667. Data on ADG, ADFI, and G:F were obtained from published peer-reviewed studies. Five data sets created: grower-finisher pigs, fully slatted floors, consistent group size; B pigs floors (group size did not need be consistent); C partially D E nursery or woven wire consistent). Each...
ABSTRACT With worldwide concern over the use of antibiotics in animal agriculture and their contribution to spread antibiotic resistance, alternatives conventional are needed. Previous research our laboratories has shown that colicin E1 is effective against some Escherichia coli strains responsible for postweaning diarrhea (PWD) vitro. In this study we examined efficacy dietary inclusion preventing experimentally induced PWD caused by F18-positive enterotoxigenic E. young pigs. Twenty-four...
The objective of this study was to estimate genetic associations for gilt growth, compositional, and structural soundness with sow longevity lifetime reproduction.

Behavioral trade off with traits through acquisition allocation resources.

The objective of this study was to develop a validated, transient, chemically induced lameness model in sows using subjective and detection tools. Experiment 1 determined an effective joint injection technique based on volume placement dye feet collected from 9 finisher pigs 10 multiparity cull sow carcasses. 2 confirmed the live animals produced transient clinical 4 anesthetized injected with amphotericin B (15 mg/mL) distal interphalangeal joints claw.

Abstract Timely euthanasia on swine farms can help to reduce the incidence of poor welfare outcomes for compromised pigs (Sus scrofa) when recovery is prolonged or impossible. relies upon caretakers’ abilities identify and administer in various environments. To determine appropriate timelines most common reasons on-farm euthanasia, an online survey was conducted with members United States National Pork Board. Additionally, two focus groups were investigate barriers possible solutions...
Introduction Precision livestock farming (PLF) technology development has proliferated recently, but on-farm adoption lagged. Understanding PLF stakeholders’ views, practical applications, limitations, and concerns are necessary to understand the factors influencing of technology. Methods Using semi-structured online interviews, 12 influential views lived experiences were investigated. A phenomenological paradigm was used generate qualitative data that analyzed using template analysis....
Pain associated with lameness on farm is a negative affective state and has detrimental impact individual animal welfare. Animal pain can be managed utilizing husbandry tools through pharmacological approaches. Nonsteroidal anti-inflammatory drugs including meloxicam flunixin meglumine are compounds used in many species for management because they easy to administer, long lasting, cost-effective. Assessing an animal's biomechanical parameters using such as the embedded microcomputer-based...
