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.

490 Research report
Benefits from cutting antibiotic use in dry cows by Mc Pherson L. 2019 British Dairying 2019: 50-52
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.

Summary:
Haemophilus parasuis is a gram-negative bacillus, responsible for Glässer’s disease, a disease with worldwide distribution characterized by fibrinous polyserositis, polyarthritis, and meningitis in swine. The incidence and prevalence of H. parasuis infection are especially high in developed countries, where it is one of the main causes of lethality and economic loss. This article make a characterization from a molecular perspective of β-Lactam resistance in Haemophilus parasuis.

In Significant Impact Groups: AMU reduction strategies \ Feed / gut health
Species targeted: Pigs;
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.

In Significant Impact Groups: AMU reduction strategies \ Feed / gut health
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: Other
Species targeted: Pigs;
Age: Not stated;
Summary:
Monitoring systems are essential for detecting changes in disease status in a timely and effective manner. This is of paramount importance to reduce the impact of outbreaks and to avoid trade restrictions. The ability to detect changes in disease occurrence depends to a large extent upon the choice of data source. The increasing availability of electronic records collected actively or passively enables the targeting of specific groups and the monitoring and prediction of specific events. Monitoring changes in mortality data and antibiotic consumption showed changes at herd level prior to and in the same month as confirmation from diagnostic tests. These results also show a potential value for using these data streams as part of surveillance strategies.

Gut Health of Pigs: Challenge Models and Response Criteria with a Critical Analysis of the Effectiveness of Selected Feed Additives — A Review by Adewole, D. I., Kim, I. H., and C. M. Nyachoti 2016 Asian-Australasian Journal of Animal Sciences Jul: 909–924
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.

G. Pantoja 2018 PLoS One 13: e0208430
In Significant Impact Groups: AMU reduction strategies \ Pathogen management
Species targeted: Pigs;
Age: Adult;
Summary:
There is growing advocacy for antibiotic-free (ABF) livestock production to minimize the emergence of antibiotic-resistant food-borne pathogens and subsequent human exposure to these treatment-refractory organisms. This trend has been driven by the escalating presence of antibiotic resistance, including multi-drug resistance, among a variety of important bacterial pathogens that infect both animals and humans. In food-animal settings, resistant pathogens include methicillin-resistant Staphylococcus aureus (MRSA), multi-drug resistant non-typhoidal Salmonella, ciprofloxacin-resistant Campylobacter spp, multi-drug resistant E. coli, and vancomycin-resistant enterococci. Under the conditions of this study, these results indicate that in a PRRSV-endemic setting involving bacterial co-infections, an ABF production strategy may leave pigs at considerable risk of exposure to severe clinical disease and that judicious use of antibiotics can significantly improve animal health.

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.
