365 Research paper – Campbell – 2019 – A review of environmental enrichment for laying hens during rearing in relation to their behavioral and physiological development

Housing and welfare \ Enrichment
Species targeted: Poultry;
Age: Young;
Summary:
Recently, there has been increasing focus on the impacts of the rearing environment on long-term behavior, health, and welfare of layers. Enriching the rearing environments with physical, sensory, and stimulatory additions can help to maximize the bird’s developmental potential. This review describes the available literature regarding enrichments provided during rearing and the subsequent impact they have on different aspects of behavioral and physiological development, including identifying the ways enrichments could have biological impact. The behaviour of the birds and their needs (dustbathing, perching, foraging) will improve their well-being and will probably result in a bird that is better able to respond to infections. But what exactly the mechanism behind the positive impact of enriched housing environments is on immunocompetence are currently poorly understood due to limited research in this area. There is a need to identify practical cost-effective enrichments that producers would use on-farm and to have commercial validation of positive impacts on aspects of behavior and biology.

364 Industry Innovation – LalFilm PRO by by Lallemand

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.

353 Industry Innovation – Health effects of on-farm hatching by WUR

In Significant Impact Groups: Housing and welfare \ New housing systems
Species targeted: Poultry;
Age: Young;
Summary:
Broilers that hatch in the barn show less mortality and have less foot sole lesions. This is shown by research of Wageningen Livestock Research that compares the traditional hatching system to on-farm hatching. The results show that chicks that hatch on farm have a better health. It seems plausible that conditions in early life influence the health and behavior of chicks for a long time. The different outcome systems show no difference in behavior in the pens. However, there are differences in the reaction when the chicks are exposed to a test situation, not only at a young age but also at an older age.

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.

350 Research paper Abdul Rasheed 2020 Effects of methylsulfonylmethane

In Significant Impact Groups: Pathogen management \ Eradication; Feed / gut health
Species targeted: Poultry;
Age: Young;
Summary:
This experiment showed promising results in the recovery of broiler chicks after a challenge with mild coccidiosis infection (E. Tenella). The chicks were fed a feed containing an additive that boosted their immuneresponse to the parasite and an additional antioxidant to mitigate tissue damage to the gut from an excessive immune response. Both the chicks on the control diet (without the new additives) and the chicks receiving the treatment were challenged with a mild coccidiosis infection and did not differ in overall performance. However, the chicks on the treatment diet showed faster recovery and better daily gain instantely after the infection with the parasite. This led the researchers to believe that chicks under a more severe infection could benefit more from this innovative dietary supportive treatment.

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements; Specific alternatives
Species targeted: Beef;
Age: Young; Adult;
Summary:
A scoping review (systematically map the literature with regard to the extent, range, and nature of the existing research) on non-antibiotic interventions in the form of products or management practices that could potentially reduce the need for antibiotics in beef and veal animals living under intensive production conditions was conducted. The objectives of this review were 3-fold: first, to examine and describe the range and nature of research on nonantibiotic approaches that may ultimately reduce the need for medically important antibiotics to prevent, control, or treat illnesses in beef and veal production; second, to identify areas where the available literature may support systematic reviews that could summarize the effect of specific non-antibiotic approaches within the broader topic area; and third, to identify knowledge gaps where additional primary research might provide valuable insight into the effectiveness of different specific nonantibiotic approaches. The four most frequent interventions included non-antibiotic feed additives, vaccinations, breed type, and feed type.

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.
