Impact of Grow-Finish Performance and Carcass Characteristics in Response to an Increased Apparent Health Challenge

. Karriker, VDPAM; John F. Patience, Department of Animal Science Summary and Implications There are a variety of health challenges that affect pork producers; these challenges can have a significant impact

Pig Age and Approachability Behavior to a Human Observer

The objective of this experiment was to determine if nursery pig age affected how many pigs touched and orientated to a human, or were classified as not-orientated during a human-animal interaction test using live human observation and digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

Distance of Nursery Pig Snout and Tails from a Human Observer during an Approachability Test

The objective of this experiment was to determine the distance of nursery pigs snout and tails from a human observer when classified as touched, orientated to the human or s not-orientated during a human-animal interaction test using a digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

Gilt and Barrow Approachability Behavior to a Human Observer

The objective of this experiment was to determine if nursery pig sex affected how many pigs touched and orientated to the human or were classified as not-orientated during a human-animal interaction test using a live human observation and a digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

The Impact of Translactational Delivered Meloxicam Analgesia on Biomarkers of Pain and Distress after Piglet Processing

Oral meloxicam was administered to sows post-farrowing to investigate a novel route of providing analgesia to processed piglets via translactational drug transfer. Physiologic indicators of piglet pain were analyzed to determine the effects on pain control. An effective meloxicam dosage was reached in 4/5 sow litters with no adverse clinical effects. Both piglet cortisol and...

Proximity of Nursery Pigs from a Human Observer during an Animal-human Interaction Test Before and After Vaccination

The objective of this experiment was to determine distance between two anatomical measures in nursery aged pigs to a human observer before and after vaccinations in their home pen using a digital image. Three treatments were compared TRT One: Saline (Saline; n =50), TRT Two: Ingelvac® CircoFLEX-MycoFLEX® (Boehringer-Ingelheim Vetmedica, Inc., St. Joseph, MO; MCFLEX; n = 48) and...

Embedded Micro-Computer Base Force Plate as an Objective Tool to Measure Hoof Lameness Phases in Multiparous Sows

The objective of this study was to compare differences in weight placed on each hoof from sows in differing lameness phases. Twelve, clinically healthy, mixed-parity, crossbred sows (228.89±19.17 kg) were used. The sow was the experimental unit and a cross-over design with a 2 (hind left and hind right hoof) x 3 (days: D-1, D+1 and D+6) factorial arrangement of treatments were...

Gait Analysis as an Objective Tool to Measure Hoof Lameness Phases in Multiparous Sows

Impact of Transmammary-Delivered Meloxicam on Biomarkers of Pain and Distress in Piglets after Castration and Tail Docking

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 biomarkers and infrared...

Using Classification Trees to Detect Lameness in Sows

Developing an automatic lameness diagnosis algorithm will benefit scientists and producers in timely and effective identification of lame individuals before clinical signs are apparent as well as aid producers in their efforts to decrease herd lameness. Being able to predict the lameness in sows can aid in delivering maximum animal health benefits, improving sow lifetime...

Yohimbine (alpha 2-antagonistic reversal agent) Effect on Return to Sensibility in Anesthetized Sows

Swine may be anesthetized in order to complete routine `production procedures or surgical operations. Swine are difficult to restrain, effectively anesthetize, and their response and reaction to anesthesia can vary substantially. The objective of this study was to determine if Y is an effective anesthetic reversal agent in mature sows. Twelve, clinically normal, mixed-parity...

A Review on the Impact of Mycoplasma hyopneumoniae Vaccination on Average Daily Gain in Swine

Mycoplasma hyopneumoniae is an enzootic pneumonia affecting swine. Globally it has been estimated that 93% of swine herds have Mycoplasma hyopneumoniae which may result in performance losses (Ross, 1992). Losses may incur from a decrease in performance, lower weight gains, decreased feed efficiency, antibiotic treatments, and an increased risk of other respiratory diseases. The...

Pharmacokinetics of flunixin meglumine in mature swine after intravenous, intramuscular and oral administration

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 (121–168 kg) were...

Blood Cortisol as an Objective Tool to Measure Painful and Non-painful Hoof Lameness States in Multiparous Sows

The objective of this study was to compare blood plasma cortisol concentrations from sows in painful and non-painful hoof lameness states. Ten, clinically healthy, mixed-parity, crossbred sows were used. The sow was the experimental unit and a cross-over design with a 2 (legs) x 3 (days) factorial arrangement of treatments were compared.On D 0, Ten mg of amphotericin B were...

Isolation and Characterization of Methicillin-Resistant Staphylococcus aureus from Pork Farms and Visiting Veterinary Students

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 experienced by veterinary...
