In Significant Impact Groups: Pathogen management \ Biosecurity
Species targeted: Pigs; Poultry; Other;
Age: Different for different species;
Summary:
All microbial species can be biofilmogenic under certain stress conditions, nutrient concentration, colony size and degree of confinement. The exchange of information and gene expressions that characterize the biofilm make it an enemy to be fought as part of the fight against antibiotic resistance. During a webinar organised by Lallemand and Unitec, a method to combat the formation of pathogenic biofilm was presented, exploiting the antagonism between bacteria. LalFilmPRO, Lallemand’s apatogenic biofilm, can be used to reverse the paradigm, using the same weapons as bacteria to extend the hygiene protocol. The exclusive technology is based on the use of specific bacterial strains, with antagonistic efficacy and high adherence power. Bacterial strains have been selected to colonise an environment quickly and uniformly, which can inhibit and antagonise the growth of other species.

357 Research paper – Mounaix – 2018 – Comparison of three protocols of vaccination against Bovine Respiratory Disease in fattening commercial farms

In Significant Impact Groups: Pathogen management \ Vaccination
Species targeted: Beef;
Age: Young;
Summary:
Three protocols of vaccination against Bovine Respiratory Disease (BRD; Bovilis Bovigrip®) for young Charolais cattle were conducted in commercial feedlots to identify respective benefits. The average daily gain was significantly higher (p<0,05) when animals were completely vaccinated (2 shots) at breeding farms (early vaccination) compared to those where part of the vaccination was done at the assembly center (intermediate vaccination). The number of cattle which were observed as sick by farmers was low in average, as well as the proportion which were treated by them (<15%/lot) but no significant difference could be demonstrated between protocols. In the context of reducing medication inputs, this experiment suggests the benefits to vaccinate cattle at the breeding farm to prevent and decrease BRD incidence in feedlots.

351 ToolsChecklists – Recommendations about biosecurity for small poultry farms by European Rural Poultry Association

In Significant Impact Groups: Biosecurity
Species targeted: Poultry;
Age:
Summary:
In a context where all poultry farms must apply strict biosecurity measures in order to protect themselves from several health threats such as Avian Influenza, ERPA, the European Rural Poultry Association, has produced two biosecurity information sheets for rural poultry farmers in Europe. These sheets are the result of a work carried out by ERPA in 2017, which first consisted of comparing the biosecurity regulations of several Member states to protect against AI, then defining homogenous biosecurity measures for all the rural poultry farmers in Europe. Simple to understand, these information sheets remind the basic principles to be respected in a poultry farm: protection of the rearing areas and management of interventions, management of the production units independently from each other, separation of palmipeds/gallinaceans, protocol of use of the changing room, application of waiting periods, and protection of animal feed, water and poultry in case of Avian Influenza in wild birds.

346 Research paper – Proudfoot – 2019 – Genome editing for disease resistance in pigs and chickens

In Significant Impact Groups: Breeding for disease resistance or robustness
Species targeted: Pigs; Poultry;
Age: Not stated;
Summary:
Targeted breeding is common practice, with measurable production traits such as feed conversion in cattle or wool production in sheep. In the late 20th century, genomic selection was added to the livestock breeding tool box achieving faster improvement in livestock production efficiency. Genome editing offers new opportunities to livestock breeding for disease resistance, allowing the direct translation of laboratory research into disease-resistant or resilient animals. Shown progress in genome editing so far in pigs and chicken are discussed (PRRS, PEDV, ASFV and ALV, avian influenza virus).The two major hurdles still to be faced prior to implementation of this promising technology are consumer acceptance and the regulatory framework.

329 Research paper – Luyckx – 2016 – Comparison of competitive exclusion with classical cleaning and disinfection on bacterial load in pig nursery units

In Significant Impact Groups: Biosecurity
Species targeted: Pigs;
Age: Young;
Summary:
Colonization of the environment of nursery units by pathogenic micro-organisms is an important factor in the persistence and spread of endemic diseases in pigs and zoonotic pathogens. These pathogens are generally controlled by the use of antibiotics and disinfectants. Since an increasing resistance against these measures has been reported in recent years, methods such as competitive exclusion (CE) are promoted as promising alternatives. Results in this study showed despite sufficient administration of probiotic-type spores, the analysed bacteria did not decrease in number after 3 production rounds in CE units, indicating no competitive exclusion. There was also no effect on feed conversion and faecal consistency (indicator for enteric diseases) was noticed. These results indicate that the CE protocol is not a valuable alternative for classical Cleaning & Disinfection protocols.

328 Research paper – Luyckx – 2016 – A 10-day vacancy period after cleaning and disinfection has no effect on the bacterial load in pig nursery units

In Significant Impact Groups: Biosecurity
Species targeted: Pigs;
Age: Young;
Summary:
Biosecurity measures such as cleaning, disinfection and a vacancy period between production cycles on pig farms are essential to prevent disease outbreaks. However, no studies have tested the effect of a longer vacancy period on bacterial load in nursery units. This study evaluates the effect of a 10-day vacancy period in pig nursery units on total aerobic flora, Enterococcus spp., Escherichia coli, faecal coliforms and methicillin resistant Staphylococcus aureus (MRSA). Three vacancy periods of 10 days were monitored, each time applied in 3 units. The microbiological load was measured before disinfection and at 1, 4, 7 and 10 days after disinfection. Results show that prolonging the vacancy period in nursery units to 10 days after disinfection with no extra biosecurity measures has no impact on the environmental load of total aerobic flora, E. coli, faecal coliforms, MRSA and Enterococcus spp.

327 Research paper – Luyckx – 2015 – On-farm comparisons of different cleaning protocols in broiler houses

In Significant Impact Groups: Biosecurity
Species targeted: Poultry;
Age: Young;Adult;
Summary:
The present study evaluated the effectiveness of 4 cleaning protocols designed to reduce the bacteriological infection pressure on broiler farms and prevent food-borne zoonoses. Additionally, difficult to clean locations and possible sources of infection were identified. Cleaning and disinfection rounds were evaluated in by sampling 12 broiler houses on 5 farms. Bacterial counts counts on the swab samples showed that cleaning protocols which were preceded by an overnight soaking with water caused a higher bacterial reduction compared to protocols without a preceding soaking step. Moreover, soaking of broiler houses leads to less water consumption and reduced working time during high pressure cleaning. No differences were found between protocols using cold or warm water during cleaning. Drinking cups, drain holes, and floor cracks were identified as critical locations for cleaning and disinfection in broiler houses.

326 – Vaccines as alternatives to antibiotics for food producing animals Part 2 (Research paper – Hoelzer – 2018)

 

 

326 Research paper – Hoelzer – 2018 – Vaccines as alternatives to antibiotics for food producing animals Part 2

In Significant Impact Groups: Pathogen management \ Vaccination; Specific alternatives
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep; Other;
Age: Young; Adult;
Summary:
This article highlights new approaches and potential solutions for the development of vaccines as alternatives to antibiotics in food producing animals. Many current vaccines fall short of ideal vaccines in one or more respects. Promising breakthroughs to overcome these limitations include new biotechnology techniques, new oral vaccine approaches, novel adjuvants, new delivery strategies based on bacterial spores, and live recombinant vectors; they also include new vaccination strategies in-ovo, and strategies that simultaneously protect against multiple pathogens. However, translating this research into commercial vaccines that effectively reduce the need for antibiotics will require close collaboration among stakeholders, for instance through public–private partnerships. Targeted research and development investments and concerted efforts by all affected are needed to realize the potential of vaccines to improve animal health, safeguard agricultural productivity, and reduce antibiotic consumption and resulting resistance risks.
