A NOVEL CONGENITAL SYNDROME WITH PALATOSCHISIS IN PIGLETS IN THE PROGENY OF A SINGLE PIETRAIN BOAR COULD BE EXPLAINED BY A DE NOVO MUTATION

Palatoschisis are oronasal fistulas, and often supposed to be inherited resulting in death. Material & Methods In a satellite farrowing farm of a sow pool system, piglets with palatoschisis were noticed in six out of thirty litters. A DNA-based examination was conducted, revealing that all affected litters were progeny of the same Pietrain boar. Thirteen affected piglets, males and females, had a unilaterale or bilaterale palatoschisis. All sows were from the same origin and had received the same feed. All littermates and their parents were sampled and the affected piglets were finally euthanized.

EVALUATION OF THE EFFICACY OF A SINGLE SHOT VACCINE, HYOGEN®, IN COMPARISON WITH A TWO SHOT VACCINE, ON PROTECTION AGAINST SWINE ENZOOTIC PNEUMONIA IN THE PARMA HAM - PIGS IN ITALY

Pigs raised for the Parma ham production in Italy are slaughtered at approximately 170kg body weight. Typical late infections like <i>M.hyopneumoniae</i> represent a severe challenge in those farms. The efficient prevention of infection and its impact on growth performance requires a long lasting immunity and protection, which can be evaluated by scoring lungs at slaughter and by recording pigs’ growth rate. Therefore, the aim of this trial was to evaluate the efficacy of a single shot vaccine, Hyogen®, in comparison with a two shot vaccine (A), on protection against Enzootic Pneumonia (EP) in Parma ham-pigs.

EUBIOTICS AS AN ALTERNATIVE STRATEGY TO ZINC OXIDE USE IN WEANING PIGS

The recent EU ban on therapeutic levels of zinc in animal diets has led to concern regarding potential performance losses and animal welfare. The aim of this trial was to evaluate a eubiotic in replacement for therapeutic zinc oxide in an E. coli challenge piglet study. Material & methods Thirty six piglets (PIC (Yorkshire × Landrace) × Duroc)) were allocated to treatment diets at weaning (21 days) for 28 days in a random block design (2 pigs per pen, 6 replicates).  All diets were formulated in excess of recommendations in NRC (2012) and were fed in a mash form. Treatments were; Control (CON), basal diet no additive; Eubiotic (EUB), organic acid blend on a mineral carrier (Anpario plc, Worksop, UK) 4g/kg; Zinc oxide (ZnO) commercially available 3g/kg.

ASSESSMENT OF SUBJECTIVE HEALTH STATUS PERCEPTION IN WEANER PIG HOLDINGS WITH RECURRING RESPIRATORY DISEASE OUTBREAKS

Respiratory diseases are identified as a priority issue in raising weaners. One approach to reduce the application of antibiotics for treatment of such respiratory diseases is to improve assessment of early disease development to maintain a good health status of the pigs after weaning. Therefore in this study the subjective respiratory disease assessing by the farmers was evaluated by comparing their individual estimation with an objective respiratory health score.   Material/Methods 30 piglet producer farms with preceding recurring respiratory diseases in weaner units were visited twice. The first visit (day1) took place when according to the farmer the health status of the weaners was not affected; the second visit (day2) when the farmer recognized a respiratory disease outbreak requiring antibiotic treatment.

HEALTH MONITORING IN NURSERY AND FINISHER PIGS BY EXTENDING DIAGNOSTIC SCREENING

Infectious diseases are of great economic importance in swine production, causing both clinical and subclinical disease influencing welfare, productivity and antibiotic use. The course of diseases is often multifactorial and laboratory diagnostics are not routinely performed. The aim of the study was to evaluate the benefit of monthly health monitoring in nursery and finisher pigs using fecal sock samples and oral fluid samples on a high-throughput qPCR platform, able to detect up to 48 pathogens, combined with serology. Materials and methods Three monthly sampling rounds were conducted in 6 nursery and 4 finisher herds.

LUNG SCORING SURVEY IN EUROPEAN COUNTRIES IN 2017

Scoring of lung lesions in slaughter pigs provides very important information about the respiratory health in the pig population. Lesions suggestive for previous M.hyo or A.p. infections and their scoring were described before. Scoring of those lesions allows quantifying the problems with enzootic pneumonia end pleuropneumonia. The aim of this survey was to collect the results of major swine producing European countries in 2017. Materials and methods Ceva Lung Program scoring methodology was implemented to score the lesions at the slaughterhouse.

ECOPORC SHIGA® VACCINATION AND PERFORMANCE IMPROVEMENT  

Introduction Edema disease (ED) is a disease due to an enteric bacteria, E. coli producing Shiga toxin 2e (Stx2e). Since October 2013, Ecoporc SHIGA®, a vaccine against Stx2e is available in France. The vaccine reduces mortality and clinical signs due to ED, but users observed that vaccinated pigs were in general healthier and showed better performance. This study was conducted to scientifically verify these observations.   Material and Methods Inclusion criteria of the farms (n = 5) were: Clinical ED post weaning and implementation of Ecoporc SHIGA® for over 1.5 year Performances registered every trimester and piglets weighted when entering fattening No significant changes in genetics or animal management, and no concomitant disease incident The comparison was made between 1 year before vaccination (trimester T-4 to T-1) and 1 full year after vaccination (T2-T5). The trimester when vaccination had been implemented (T0) and the following (T1) were excluded; therefore the effect of the ED crisis itself was not evaluated.

VACCINATION FAILURE/SUCCESS – ARE VETS DOING A PROPER MANAGEMENT OF ON-FARM VACCINATION?

Sometimes a vaccination strategy that you recommended did not present the expected results? It can be frustrating when you did an excellent veterinary work, with accurate diagnostics, proper selection of vaccine and vaccination program, and in the end it didn´t work. In our practice we evaluated vaccination success and failure in over 50 farms for several diseases (Aujeszky´s, PCV2, MHYO, PRRS and Bordetella) and found that this is highly influenced by the PEOPLE that manage on-farm vaccination procedures. We implemented a program (Plan.Explain.Demonstrate.Register.Audit.) to improve vaccination success involving Vets, farm managers and workers.

PREVALENCE OF MATERNALLY DERIVED IAV ANTIBODIES IN SUCKLING PIGS IN 28 US SWINE HERDS

Influenza A virus (IAV) is known to persist in swine breeding herds. The herd level prevalence of IAV and within herd prevalence of IAV antibodies in US swine herds is poorly understood.   Materials and Methods: A convenience sample of 28-mixed parity herds (inventory >2000) from 7 states were enrolled. A 73-question survey identified herd characteristics and management practices. Three to five day old piglets were sampled in three separate cohorts at monthly intervals. Each consisted of 2 pigs from 24 litters (n=48) stratified over three dam parity groups. Antibodies in serum against IAV were detected with three assays: 1) NP ELISA assay (NP), 2) Hemagglutination Inhibition (HI) assay against H1N1 (H1) and 3) an HI assay against H3N2 (H3).

THE COUGH INDEX CALCULATOR APP: US EXPERIENCE WITH THE TOOL IN A LARGE SCALE FIELD TRIAL

Coughing pigs are a common complaint that producers report and veterinarians make recommendations to address.  The measurement of cough is subjective, e.g. “better or worse”, or categorical, e.g. mild, moderate or severe, which makes the assessment of an intervention based on cough challenging.  In 2016, a free, app-based tool was published by Boehringer Ingelheim Animal Health Gmbh to make the measurement of cough more standardized and objective in a production setting.  The tool is a Cough Index Calculator and results in a cough index score.
