EVALUATION OF A NEWLY KIT, MULTIPLEX REAL-TIME RT-PCR METHOD FOR THE DETECTION OF SWINE CORONAVIRUSES (PEDV, TGEV AND SDCOV)

The coronaviruses, porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), and porcine delta coronavirus (PDCoV) are causative agents for gastrointestinal diseases in pigs. All three coronaviruses show similar initial clinical signs, but treatments and remediation may be different for each. Tests specific for each of these can advise the course followed, greatly aiding herd management. The Applied Biosystems™ VetMAX™ PEDV/TGEV/SDCoV Kit is an assay that detects and differentiates the three coronavirus species in a single reaction mix.

EFFECTS OF DIFFERENT FEED PROGRAMS ON SECOND LITTER SYNDROME IN AFTER FIRST WEANING TO SECOND PARITY SOWS

Introduction: It is well known that second parity sows may have low farrowing rate or low reproduction performance. Furthermore, it made a negative impact on farm productivity. Hence, improving reproductive performance of second parity sows might improve farm productivity. This experiment was conducted to evaluate the effects of different feed programs on reproductive performance, litter performance and second litter syndrome in after first weaning to second parity sows. Material & methods: The experiment was started when sows in the first weaning, and a total of 52 sows, average body weight (BW) of 173.4 kg, were allotted to one of four treatments based on BW and backfat thickness with 4 treatments and 13 replicates.

EFFECTS OF FEEDING FREQUENCY DURING EARLY GESTATION ON REPRODUCTIVE PERFORMANCE IN GESTATING SOWS

Introduction: Our research group has been used daily once feeding to gestating sows from 35 day for saving labor and its cost. The period of once daily feeding in previous study was the day after pregnancy checking (35 day) due to concerns about conception and pregnancy in early gestation. To improve once daily feeding scheme, this study was conducted to evaluate the effects of feeding frequency during early gestation on reproductive performance in gestating sows. Material and Methods: A total of 40 multiparous sows (Yorkshire x Landrace, average parity 4.1) were used in this experiment.

A NORWEGIAN PROJECT STUDYING OUTBREAKS OF ACUTE RESPIRATORY DISEASE IN FATTENING PIGS

Introduction The Norwegian pig population has a favorable health status when viewed in an international perspective. The population is free from Mycoplasma hyopneumoniae and several viral agents [(PRRSV, PRCV, SIV (except H1N1pdm09)] involved in respiratory infections in pigs. However, over the last four years, there has been an increase in reported cases of acute respiratory disease in the Norwegian pig population. The project aims to investigate the etiology and risk factors of outbreaks of respiratory disease in Norwegian pig herds.

INVESTIGATION OF PORCINE RESPIRATORY DISEASE COMPLEX (PRDC) OUTBREAKS AT POST-WEANING IN FARMS FROM WESTERN FRANCE USING A NEW BRONCHOALVEOLAR LAVAGE TECHNIQUE  

Recently, a French swine practitioner developed a bronchoalveolar lavage (BAL) sampling method that uses two catheters and can be performed on live, unsedated pigs without causing undue stress. The trachea is accessed via the mouth. In its diagnostic support services to practitioners, Zoetis’ technical service in France implemented this sampling method in the field when requested by practitioners. The experience from  31 farms with respiratory disease post- weaning in 2015-2016 is summarized.

A NEW APPROACH TO DETECT REPRODUCTIVE DISEASE OUTBREAKS USING SOW PRODUCTION RECORDS. A FOCUS ON PRRSV

Porcine reproductive and respiratory syndrome (PRRSV) is a viral disease with negative impact on sow reproduction, being associated to a decrease in the number of born alive piglets (NBA) and an increase in the number of lost piglets (NLP). It is of interest to quickly assess whether a farm is under a PRRSV outbreak situation. The aim of this research work is to develop a new method to distinguish between healthy and disease phases in PRRSV positive and negative farms using performance data.   Material & Methods NBA and NLP records from a farm were used.

EFFECT OF FARM MANAGEMENT PROCEDURES ON THE PRODUCTIVE PERFORMANCE IN A PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME (PRRSV) VIRUS INFECTED FARM USING PDP MODELS

Several strategies to control PRRSV have been described such as implementing a gilt acclimation protocol, a PRRSV vaccination program for gilts and sows and to control the spread of pathogens in suckling pigs. In this context, the impact of management procedures, focus on limiting the transmission of infectious agents through the population (non-mixing litters and limit cross fostering), has not been deeply analyzed. The aim of this research work is to use PDP models to decipher the impact of different management decisions on the epidemiology of PRRSV under field conditions.

 ARE PIGS WITH IRON DEFICIENCY LESS ABLE TO PRODUCE ANTIBODIES IN RESPONSE TO VACCINATION COMPARED TO PIGS WITH ADEQUATE IRON STATUS? 

Iron deficiency is common among newly weaned fast growing pigs and it is possible iron status is associated with immune function. Pigs are often vaccinated at weaning for diseases they will face in the grower stage of production. The objective of this research trial was to determine if antibody production in response to vaccination against Mycoplasma hyopneumoniae is affected by the iron status of pigs at the time of vaccination. Material and Methods: Three different iron treatment groups were created.

CONSIDERATIONS FOR ASSESSING THE IMPACT OF INFLUENZA IN GROWING PIGS

Observational studies have reported the cost of IAV-S in swine production systems to range from approximately US$3-10 per growing pig. At this time there is no standard method to assess the impact of interventions targeted against IAV-S. Here we propose key parameters which, when collected in the growing phase, provide insight into the association of pathogens and disease presence with key performance indicators (KPI). Materials and Methods: The measurable unit of growing pigs is defined as a group of pigs that starts and markets together, resulting in a single closeout. Collecting routine measurements in multiple groups, over time is necessary for assessment.
