DETERMINING THE OPTIMAL NUMBER AND CONFIGURATION OF SOUND MONITORING DEVICES FOR DETECTING AND ASSESSING DIRECTIONALITY OF COUGH IN GROWING PIGS

Continuous sound monitoring systems have been shown to better detect clinical episodes of respiratory disease. However, microphones used in such systems have distance limits of sound detection. The purpose of this project was to evaluate the optimal placement and configuration of a continuous sound monitoring system in large airspace buildings containing growing pigs to enable both a high sensitivity for detection and establishing directionality of clinical respiratory episodes. Materials and Methods Cough monitors (SOMO+ Respiratory Distress Monitor, SoundTalks NV, Leuven, Belgium) were obtained and installed in three large commercial wean-to-finish facilities designed to house 1200 to 2400 pigs per airspace.

A STUDY OF TILMICOSIN SUPPLEMENTATION IN FEED AND IT'S EFFECT ON LACTATION PERFORMANCE IN SOWS

Porcine Reproductive and Respiratory Syndrome (PRRS) is considered as the most economically important diseases in pig industry worldwide. Active infection during farrowing period cause vertical transmission of PRRSv from sow to piglets. Umbilical blood testing can be used to identify such transmission. Tilmicosin, a macrolide antibiotic has been reported to reduce the severity of PRRSv infection in nursery pigs. Moreover, tilmicosin provides activity against PRRSv. The objective of this study was to investigate the effect of tilmicosin (Pulmotil<sup>®</sup>) supplementation in sows feed prior to farrow and during lactation on lactation performance parameters in a farm with PRRSv infection.

IS SKIN TEMPERATURE RELIABLE AS CORE BODY TEMPERATURE INDICATOR?

The circadian system is based on a multioscillatory neural network that generates and sends a temporal signal throughout the entire organism, which drives biological rhythms. From the main marker rhythms of the circadian system core body temperature (CBT) and skin temperature (ST) are two of the most used due to its reliability and ease of use, respectively. Thus, the aim of this study is to check the reliability of ST as CBT indicator. MATERIAL AND METHODS Thermochron iButton DS1921H (Maxim Integrated Products, Sunnyvale, California) were used to measure CBT and ST with a precision of ±0.125°C and a sample rate of 1 minute during 1,4 days.

EFFECTS OF HISTOPATHOLOGICAL ABERRATIONS ON LUNG FUNCTION IN PIGS

Diseases of the respiratory tract are often summarized as the “porcine respiratory disease complex” (PRDC). PRDC shows a high variability in the field. Because of a wide spectrum of etiological factors, diagnosis needs to combine clinical examination, dissection and the isolation of pathogens. Impulse oscillometry (IOS) might be a new, non-invasive method that could add valuable information from living pigs. The aim of the present study was to validate IOS in pigs with respiratory diseases based on their associated histopathology.

SURVEY UPDATE ON MYCOPLASMA HYOPNEUMONIAE ACCLIMATION OF GILTS IN THE SPANISH SWINE INDUSTRY

The introduction and management of replacement gilts is an important topic with regard to the control of Mycoplasma hyopneumoniae in the farm. Improper acclimation may result in colonization of the suckling piglets and increased M. hyo related respiratory disease in growing pigs. This survey is the second part of a previous one on the same subject in the Spanish swine farms.     Materials and Methods   The survey included 16 questions designed to identify which gilt acclimation methods for M. hyo are currently used in Spanish farms nowadays.

AIRBORNE DETECTION OF SWINE INFLUENZA A VIRUS, PRRS VIRUS AND MYCOPLASMA HYOPNEUMONIAE IN FRENCH SWINE HERDS

The detection in bioaerosols of three pathogens involved in the porcine respiratory disease complex (PRDC), namely swine influenza A virus (swIAV), porcine reproductive and respiratory syndrome virus (PRRSV) and Mycoplasma hyopneumoniae (Mhp), was evaluated in six pig herds affected by PRDC.   Material & methods The herds were previously known to be affected by swIAV, PRRSV and Mhp. Bioaerosols were collected using a wet cyclone technology (Coriolis®µ air Sampler). In all herds, air samples were taken in rooms housing pigs. The loading area with pigs waiting for the slaughterhouse delivery was sampled in two herds.

PRRSV IGM-IGA ELISA DETECTS INFECTION IN THE FACE OF CIRCULATING MATERNAL IGG ANTIBODY 

Oral fluids (OF) are used extensively for PRRSV surveillance: qRT-PCR detects active infection and antibody ELISA is useful for establishing prior exposure.  However, in weaned pig populations originating from PRRSV infected and/or vaccinated sow herds, colostral IgG cannot be differentiated from IgG produced by the pigs in response to infection.  To address this problem, we developed and evaluated IgM- and/or IgA-specific oral fluid ELISAs as a means to detect PRRSV infection in weaned pig populations with circulating colostral antibody.

SPATIAL AUTOCORRELATION AND WHAT IT MEANS FOR SWINE SURVEILLANCE 

Spatial autocorrelation is based on Tobler’s 1st law of geography:  “everything is related to everything else, but near things are more related then distant things.”  This simple concept has huge implications for the way we conduct disease surveillance.  In a recent study, spatial patterns associated with the spread of PRRSV were explored using oral fluid sampling data. Materials & Methods</strong> Oral fluids were collected from every occupied pen (108 pens; ~25 pigs per pen) in 3 commercial wean-to-finish barns on one finishing site for 8 weeks for a total of 972 OF samples.

SURVEILLANCE OF EDEMA DISEASE IN NURSERY AND FATTENING SWINE FARMS.

Edema disease (ED) in pigs is caused by verotoxigenic strains of Escherichia coli producing Vt2e. Currently, a bacteriology test is the gold standard to confirm Vt2e infection, which is a resource-intensive process. The aim of this study was to test an alternative diagnostic method for ED surveillance, based on the detection of bacterial shedding in growing pigs. Material & Methods A descriptive longitudinal study was conducted in the nursery and fattening units of 5 farms. Individual rectal swabs (RS, n=30-50/cohort) and pen oral fluids (OF, n=3-7/cohort) were collected at the entrance in the nursery, at 6-7 weeks of age, at the entrance in fattening unit, at 15-16 weeks of age and at the end of the fattening unit. Samples were assessed for Vt2e by real-time PCR.

COLOSTRUM HERITABILITY IN SOWS

<strong>Introduction: </strong>Pork production has experienced tremendous genetic progress, which has been achieved an increase in litter size and survival of young piglets; this resulting in an increase of piglets at farrowing and negative consequences as higher variability in weight and higher percentage of weak piglets that compromise his vitality and require intensive care. Thinkinpig studied heritability of colostrum since colostrum is the first food for piglets at birth being essential the intake to reduce mortality pre-weaning. The aim of this study is to analyze colostrum heritability and assess this parameter to include in selection programs.

STRATEGIC MEDICATION OF SUCKLING PIGLETS

Strategic medication of piglets in the first week of life is common to prevent umbilical hernias, arthritis, and other infections. In Denmark, the drugs used can roughly be grouped into penicillins/amoxycillins and long-term acting macrolides. Due to the public debate about antibiotic resistance, some farmers are reluctant to use macrolides, but in some cases the clinical problems cannot be handled by administration of penicillins or amoxycillin.   Materials & methods This study was set up in a Danish 800 sow herd with high prevalence of umbilical hernias despite strategic medication of all piglets on day 1 after birth.
