Preconditioning systems: a solution to decrease respiratory diseases in young bulls fattening units? by Vanbergue, E., Assie, S., Mounaix, B., Guiadeur, M., Aupiais, A., Cebron, N., Meyer, G., Philibert, A., Maillard, R. and G. Foucras 2020 Rencontres Recherches Ruminants : 25°
In Significant Impact Groups: Pathogen management \ Vaccination, Feed / gut health
Species targeted: Beef;
Age: Young;
Summary:
Preconditioning of young bulls is implemented to prevent bovine respiratory diseases occurence in fattening units. A control/case study was set up in nine cow-calf operations and four fattening units to compare preconditioned and control cattle in a French context. Preconditioning protocol consisted of weaning calves 50 days before sale, with adaptation to solid feedstuff and housing. A trivalent vaccine protocol (BRSV, BPI3, Mannheimia haemolytica) and vitamins and micronutrients supplementation was also implemented in order to improve immunity to respiratory diseases. Contrary to what was expected, diseases incidence and lung lesion score were higher for preconditioned young bulls compared to controls. These results could be explained by the epidemiology context of fattening units, poor housing conditions in cow-calf herds and individual immune competence, in relation to immune status and previous vaccination. Pathogens detected in fattening units (BCoV, Pasteurella multocida…) were essentially different from the vaccine valences. This study identifies critical parameters for the settlement of preconditioning programs, and highlights the necessary adaptation to local conditions and husbandry factors.

Involve to help dairy farmers to improve practices. by Mounaix, B., Guiadeur, M., Jozan, T. and S Assie 2020 Rencontres Recherches Ruminants 2020: Session Santé
In Significant Impact Groups: Pathogen management \ Vaccination Biosecurity
Species targeted: Dairy; Beef;
Age: Young; Adult;
Summary:
The relationship between farmers’ attitude and on farm practices has been demonstrated. A trial to test dam vaccination on calf protection has permitted to survey 36 dairy farmers on their perception of this practice: 6 months before the trial (2017), 77% of them had a preventive perception of the vaccination but they associated it to rather curative practices. Their implication through the trial has improved their understanding of calf passive immunity and of the role of colostrum into this process (75% of answers), but also the importance of the delay for colostrum intake (72%) and of the quality of colostrum (65%). After the trial, the farmers declared to be determined to change their practices regarding the distribution of colostrum to improve the health of calves at farm. These results confirmed the benefits of practical application to facilitate the changes in attitude and practices.

492 Research paper
Concomitant vaccination of cows and awareness to colostrum distribution: positive impacts on veal calves strength by Mounaix B., Chanteperdrix M., Jozan T. and S. Assie 2020 Rencontres Recherches Ruminants : Session santé
In Significant Impact Groups: Pathogen management \ Vaccination; Biosecurity
Species targeted: Beef; Dairy;
Age: Young; Adult;
Summary:
The impact of the concomitant vaccination of cows to protect the young calf against neonatal diarrhoea and respiratory diseases was tested: in 40 dairy farms, 819 dams were vaccinated at drying with recommendation to distribute to their calf 4L of colostrum within 6 hours after calving. 211 calves of those vaccinated cows and 214 calves without known history were compared in 10 veal calves fattening farms. Within the first 45 days, calves from vaccinated cows received 1 antibiotic treatment less than other calves and less antibiotic matter. The impact was visible from the arrival at fattening unit: 1.8 less risk for vaccinated cow calves to show clinical respiratory disease, and a higher weight (1 kg) at equivalent ages. As a consequence, the mortality of calves from vaccinated cows was lower.

Vaccination schedules in small ruminant farms by D.Lacastaa, L.M.Ferrera, J.J.Ramosa, J.M.Gonzálezb, A.Ortína, G.C.Fthenakisc, 2015 Veterinary Microbiology 181: 34-46
In Significant Impact Groups: Pathogen management \ Vaccination
Species targeted: Sheep;
Age: Adult;
Summary:
Development and implementation of health management plans is the cornerstone of profitable farms; prevention of microbial diseases by means of vaccination is an integral part of such a plan. In every production type and management system in small ruminants, microbial diseases have a major significance, hence their proper control must be based in good health management practices, including use of effective and safe vaccines. The article reviews and discusses vaccination programs and latest advances in development of vaccines against diseases that cause major economic losses in small ruminants.

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

 

 

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.

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.

In Significant Impact Groups: Pathogen management \ Vaccination; Specific alternatives
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Young; Adult;
Summary:
Vaccines and other alternative products can help minimize the need for antibiotics by preventing and controlling infectious diseases in animal populations, and are central to the future success of animal agriculture. This article, synthesizes and expands on the expert panel discussions regarding opportunities, challenges and needs for the development of vaccines that may reduce the need for use of antibiotics in animals. Vaccines are widely used to prevent infections in food animals. Various studies have demonstrated that their animal agricultural use can lead to significant reductions in antibiotic consumption, making them promising alternatives to antibiotics. To be widely used in food producing animals, vaccines have to be safe, effective, easy to use, and cost-effective. Although vaccines have the potential to improve animal health, safeguard agricultural productivity, and reduce antibiotic consumption and resulting resistance risks, targeted research and development investments and concerted efforts are needed to realize that potential.
