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.

Species targeted: Dairy; Pigs;
Age: Not stated;
Summary:
Agro-ecological transition of livestock farming systems requires strong changes in animal health management, toward more preventive approaches of livestock practices, e.g. feeding management, and less use of medical inputs for animal. These systemic changes concern farm managers but also their advisors and teachers. In this study, surveys have been made to study the particular needs of farmers and their advisors for education, both professional and academic. These surveys were realised with advisors and farmers of different educational backgrounds, from pork and dairy sector. Results of these surveys show a very small contribution of initial and academic education for useful knowledge on health management , expressed by farmers and advisors ; they also show strong needs addressed toward professional training, that should combine peer exchanges of practises, practical exercises and specialized knowledge coming from animal health experts.

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.

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.

In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics; Prudent use AB
Species targeted: Dairy;
Age: Not stated;
Summary:
Selective Dry Cow Therapy (SDCT) is becoming more common on many dairy farms in response to increasing pressure to use antibiotics responsibly in agriculture, as well as the demands from milk buyers and supermarkets. Trials have shown that cows with no evidence of existing infection within the udder can be successfully dried off with only a teat sealant. The use of antibiotic dry cow therapy can then be targeted to only those cows with evidence of infection at dry off—usually indicated by a high somatic cell count in late lactation.

Age: Young;
Summary:
Antibiotics (AB) are an effective tool to control and treat infectious diseases in intensive production systems where high densities of animals facilitate the spread of pathogens. However, there is an overreliance on their usage and farmers often see them as the only solution to disease challenges. Prophylactic use of AB in feed around weaning is common on Irish pig farms. This could contribute to create AB resistance which is a major global concern for human as well as animal health. This study has shown removing AB from the feed of weaner pigs had minimal effects on health and welfare indicators.

Species targeted: Pigs;
Age: Not stated;
Summary:
The pig industry uses more medication (mg of active ingredient / population correction unit) than other livestock sectors, especially during the weaning period when pigs face several challenges and stressors including changes in diet, separation from the sow and re-mixing. These changes stress the animals and compromise their immune system, making them more susceptible to infectious agents. This study conclusion suggests that the removal of prophylactic in-feed antibiotics is possible with only minor reductions in productive performance and health which can be addressed by improved husbandry and use of parenteral antibiotics.

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Pigs;
Age: Not stated;
Summary:
To improve productivity of pigs, researchers have evaluated a wide range of feed additives (such as immunoglobulin, omega 3 fatty acids, yeast derived B glucans, organic and inorganic acids, high levels of zinc oxide, essential oils, herbs and spices, some types of prebiotics, bacteriophages and anti-microbial peptides, probiotics, glutamine, threonine, cysteine, and nucleotides) as substitute products for antibiotics. One approach to evaluate the effectiveness of these additives in vivo is to use an appropriate disease challenge model. Over the years, researchers have used a number of challenge models which include the use of specific strains of enterotoxigenic Escherichia coli, bacteria lipopolysaccharide challenge, oral challenge with Salmonella enteric serotype Typhimurium, sanitation challenge, and Lawsonia intercellularis challenge. These challenge models together with the criteria used to evaluate the responses of the animals to them are also discussed in this review.

Species targeted: Pigs;
Age: Young;
Summary:
Neonatal piglet diarrhea is a major cause of pre-weaning mortality, resulting in significant economic loss for swine producers. The relative importance of different diseases contributing to neonatal diarrhea in piglets appears to be changing, possibly because of changes in husbandry and management practices, advances in diagnostic techniques, and/or the emergence of new diseases.This study shows that E. coli, C. perfringens type A, rotavirus, and C. difficile are enteric pathogens of concern for Ontario swine farrowing operations and further research is required to understand the reasons for the cases that are not diagnosed.
