219 Research paper – Olofsson – 2014 – Patterns of between-farm contacts via professionals in Sweden

In Significant Impact Groups: Biosecurity \External biosecurity
Species targeted: Dairy;
Age: Adult;
Summary:
The objective of the study was to examine the travel patterns of professionals visiting Swedish farms (veterinarians, milk tanker drivers, artificial inseminators, maintenance technicians and livestock hauliers). There were twelve participating organisations, and data was provided for one to three individuals/vehicles/veterinary practices per professional category and per geographic region (except for dairy service technicians and livestock hauliers who did not provide data from all regions). Generally, the greatest areas were travelled by milk tankers and livestock hauliers, and the profession travelling over the smallest areas tended to be the veterinarians. The results of this study indicate that in Sweden a highly contagious disease might spread over a large area in the time span of one incubation period, which ought to be kept in mind in case of an outbreak and in outbreak investigations. The difficulties in contacting some professionals visiting farms could be a problem in an outbreak situation.

In Significant Impact Groups: Biosecurity \External biosecurity
Species targeted: Pigs; Dairy;
Age: Adult;
Summary:
Registration of cattle and pig movements is mandatory in Sweden and all registered movements between farms in the years 2006-2008 were investigated. The networks were analysed as monthly and yearly networks, separately per species and with the two species together. Many farms had few or no contacts, while others had many, a pattern which has also been described from other countries. The cattle network and the combined network showed a recurring seasonal pattern, while this was not seen in the pig network. The in-degree was not equivalent to the ingoing infection chain; there were holdings with limited direct contacts, but a large number of indirect contacts. The ingoing infection chain could be a useful measure when setting up strategies for disease control and for risk based surveillance as it identifies holdings with many contacts through live animal movements and thus at potentially higher risk for introduction of contagious diseases.

In Significant Impact Groups: Pathogen management
Species targeted: Dairy;
Age: Adult;
Summary:
Financial resources may limit the number of samples that can be collected and analysed in disease surveillance programmes. In this paper, the association between two network analysis measures, i.e. ‘in-degree’ and ‘ingoing infection chain’, and signs of infection is investigated. Results show that compared to completely random sampling these approaches increase the number of detected positives, both for BCV and BRSV in our study population. It is concluded that network measures for the relevant time period based on updated databases of animal movements can provide a simple and straight forward tool for risk-based sampling.

216 Research paper – Frossling – 2014 – A novel method to identify herds with an increasedprobability of disease introduction due to animal trade

In Significant Impact Groups: Biosecurity \External biosecurity
Species targeted: Dairy;
Age: Adult;
Summary:
This paper presents a new method to assess herd disease risk in animal movement networks. It is an improvement to current network measures that takes direction, temporal order, and also movement size and probability of disease into account. In the study, the method was used to calculate a probability of disease ratio (PDR) of herds in simulated data sets, and of real herds based on animal movement data from dairy herds included in a bulk milk survey for Coxiella burnetii. The results show that the PDR is able to capture the different circumstances related to disease prevalence and animal trade contact patterns. The method shows a potential to be useful for risk-based surveillance, in the classification of herds in control programmes or to represent influential contacts in risk factor studies.

In Significant Impact Groups: AMU reduction strategies
Species targeted: Sheep;
Age:
Summary:
The SHAWG guidance document has been written to outline the key steps in ensuring veterinary surgeons and farmers work together to review and achieve responsible use of antibiotics within the sheep flock. Examination of antibiotic use in the sheep sector, identified the following three areas of concern with regards to prescribing practices for sheep. In some cases these involved whole flock prophylactic treatment for these three specific disease management areas: control of infectious lameness, prevention of enzootic abortion and treatment of lambs against neonatal bacterial infections. The primary recommendations are that, in order to replace, refine and reduce antibiotics in these target areas, vets and sheep farmers should work to plan ahead, prevent disease and protect their flocks.

214 Industry Innovation – Essential Oils in Drinking Water_ Using Flexibility and Speed to Help Poultry During Gut Health Challenges by Biomin

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Poultry;
Age: Adult;
Summary:
While adding phytogenic feed additives (PFAs) to feed is the most common application method, many producers are realizing the benefits of including PFAs in drinking water. PFAs can be used to tackle necrotic enteritis (NE) in poultry, a challenge likely to result in decreased feed intake. Bans on the use of antibiotic growth promotors in livestock production around the world have resulted in a performance gap. Phytogenic feed additives (PFAs) can help bridge the gap due to their beneficial biological effects. Drinking water application of PFAs (example of Digestarom® P.E.P. sol.) ensures they are delivered to the gut during times when they are most needed. Drinking water application of PFAs is flexible and quick and is increasing in popularity. Application can take place in combination with other additives such as organic acids, probiotics, or vaccines. Improved broiler gut quality and function results in reduced disease incidence and less treatment costs.

Species targeted: Poultry;
Age: Adult;
Summary:
Even with good management, bacterial infections stemming from the imbalance of the gut microbiota can cause production losses in layers. Preventive nutrition strategies that support gut performance can offer a cost effective alternative to antibiotic application, particularly around peak production. In fact, unsaleable eggs and the challenge of drug-resistant bacteria can make antibiotic application more expensive than non-antibiotic alternatives. Organic acids and phytogenic feed additives have been accepted as an efficient tool to prevent and control disease proliferation in poultry. The case of a commercial layer farm in Hungary illustrates how preventive nutritional strategies using novel feed additives can offer a profitable alternative to antibiotics in cases of chicken disease.

In Significant Impact Groups: Prudent use AB \ Veterinarian; AMU reduction strategies
Species targeted: Pigs;
Age: Not stated;
Summary:
The potential effects of the Yellow Card intervention, enforced by Danish authorities since 2010 on the antimicrobial prescription in the Danish pig production were investigated. Descriptive analysis of temporal trends in quantitative antimicrobial prescription for pigs were performed for each administration route, age and disease group. There was a 25% decline in the total antimicrobial use per pig produced between 2009 and 2011, both in sows, piglets, weaners and finishers. Reduced prescription of some antibiotics for oral use in weaners and finishers explained 76% of the total reduction. In 2012, the overall antimicrobial use increased by 10%, as a result of slight changes of prescription patterns. On herd level, the decline and subsequent increase was mainly related to changes in number of herds receiving regular monthly prescriptions. The steep decrease in antimicrobial use in the Danish pig production was temporally related with the announcement and introduction of the Yellow Card intervention.

In Significant Impact Groups: Biosecurity \External biosecurity
Species targeted: Pigs;
Age: Not stated;
Summary:
One hundred Spanish pig farms were surveyed to determine the biosecurity measures currently applied, as reported by farmers, and to investigate the importance awarded by farmers and veterinarians to each of these measures. Data was gathered by means of a questionnaire administered to farmers and veterinarians. Biosecurity measures were reported based on two scenarios: presence and absence of a highly contagious disease. The effect of farm type on the biosecurity level was also investigated. Farmers awarded significantly higher scores to their farms’ biosecurity than the veterinarians. According to both, the most important biosecurity measures were those aimed at minimising the risk of disease introduction by visits and vehicles. Biosecurity practices seeking to reduce the risk of disease introduction by breeding stock were not applied in many farms. Medium-sized to large farms located in high pig density regions reported higher biosecurity measures than small herds located in low pig density areas.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Pigs;
Age: Adult;
Summary:
The monitoring of the antimicrobial resistance of Escherichia coli commensal strains isolated from caecal samples collected from slaughtered pigs was implemented for the first time in Romania, in 2015, by testing a number of 399 samples. The prevalence of commensal ESBL/AmpC producing E. coli strains isolated from the slaughtered strains were resistant to cefotaxime (100%), ampicillin (100%), cefepime (91.93%), ceftazidime (90.13 %), sulfamethoxazole (73.54%), tetracycline (71.30 %), trimethoprim (62.33%), ciprofloxacin (53.81%), chloramphenicol (41.70%), nalidixic acid (39.91%), gentamicin (20.63%), cefoxitin (20.63%), azithromycin (14,35%), colistin (3.59%), ertapenem (1.79%). This survey shows that the pigs slaughtered in Romania during the year 2015 were colonized, in a proportion of more than 60%, with strains resistant to cephalosporins, sulfonamides, tetracyclines and fluoroquinolones. The results obtained will provide important insight into effects of using antimicrobials at animals.
