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.

Age: Not stated;
Summary:
Wild animals foraging in the human-influenced environment are colonized by bacteria with clinically important antibiotic resistance. The occurrence of such bacteria in wildlife is influenced by various biological, ecological, and geographical factors which have not yet been fully understood. More research focusing on the human-animal-environmental interface and using novel approaches is required to understand the role of wild animals in the transmission of antibiotic resistance and to assess potential risks for the public health.

Effect of welfare standards and biosecurity practices on antimicrobial use in beef cattle by Diana, A., Lorenzi, V., Penasa, M., Magni, E., Alborali, G. L., Bertocchi, L., & De Marchi, M. 2020 Scientific Reports 10: 13-Jan
In Significant Impact Groups: Housing and welfare \ Weaning age and management; Biosecurity
Species targeted: Beef;
Age: Young; Adult;
Summary:
This study aimed to investigate the impact of welfare standards and biosecurity on AMU in beef cattle. Data on performance traits and AMU were collected over a 3.5 year time from 27 specialised beef farms and a treatment incidence was calculated using the defined daily dose for animals. An on-farm assessment was carried out. The highest average score was obtained for the welfare section (76%) followed by emergency management (39%) and biosecurity (24%). This suggests that major focus on strategies for the implementation of biosecurity measures and emergency management is needed, due to the low scores reported. A statistically significant lower AMU was observed with improved level of welfare. These results may be helpful for farm benchmarking and highlight the importance of improved animal welfare for an efficient antimicrobial stewardship

Age: Not stated;
Summary:
Hydrolysis of death animals is a system for an intermediate storage of cadavers during at least 6 months. The main advantages are: (i) bacterial and virus control in the environment because hydrolysis produce an inactivation of the majority of the pathogens, and (ii) reduce the carcass collection frequency. It is not needed to collect the death animals once or twice per week, with this system the carcass collection is once or twice per year.

Comparing Farm Biosecurity and Antimicrobial Use in High-Antimicrobial-Consuming Broiler and Pig Farms in the Belgian–Dutch Border Region by Caekebeke, N., Jonquiere, F. J., Ringenier, M., Tobias, T. J., Postma, M., van den Hoogen, A., Houben, M. A. M., Velkers, F. C., Sleeckx, N., 2020 Veterinary Science 7: 11-Jan
In Significant Impact Groups: Biosecurity \Internal biosecurity; Animal
Species targeted: Pigs; Poultry;
Age: Young;
Summary:
On average, more biosecurity measures were implemented on Dutch farms, compared to Belgian farms in both animal species. In addition, more opportunities were found to increase the level of internal biosecurity compared to external biosecurity in both countries. There was a substantial difference in AMU between farms from both countries. In both poultry and pig production, the majority of antimicrobials used were extended-spectrum penicillins. Compared to Belgian farms, Dutch poultry farms used high amounts of (fluoro)quinolones (1 and 15% of total AMU, respectively). None of the production parameters between broiler farms differed significantly, but in pig production, weaning age in Belgian farms (median: 23) was lower than in Dutch farms (median: 27). These results indicate considerable room for improvement in both countries and animal species. Farm-specific preventive strategies can contribute to lowering the risk for animal disease and hence the need for AMU.

Hoof trimming in dairy cows

/in , , /by

Diseases of the hoof affect the welfare of the animal and require expensive treatments, with negative effects on milk production and reproductive activity. Studies conducted worldwide estimate that the prevalence of laminitis is between 20 and 30%. The dairy cow is expected to produce large amounts of milk, often leading to combined problems of the udder and hooves. The pressure on the cow’s body to produce milk determines a metabolic stress that decrease her immunity.

The main causes of diseases of the hoof in cows are: high stocking densities in the stable; poor quality of the floor on which the cow treads, frequent changes to grouping, excessive energy and protein from the feed ration, and genetics (the problems of the hooves are inherited through breeding).

Several measures can help to prevent hoof diseases in dairy cows, such as: maintaining good hygiene in the shelters, keeping the floors of the barn clean and dry; bathing the hoof of the cows before or after leaving the milking parlour and maintaining the same bath for a period of 2-3 days; periodic trimming, at least 2-3 times a year; feeding rations which are energy and protein balanced during the transition period; reducing the frequency of modifications to the feed rations; and ensuring feeds utilise good quality fats according to nutritional requirements.

In the dry period, the concentrated feed should be reduced, or even eliminated, from the ration, and after calving the inclusion of concentrates should gradually increase. The addition of Zinc to the ration has favourable effects on the skin and the hooves. Furthermore, animal breeding should be directed towards obtaining animals with strong bones, correct statutre and resistance to hoof diseases.

Biosecurity measures on Pig Farms

/in , /by

 

Biosecurity is ensured on a pig farm by implementing a set of organizational and technical measures in order to prevent the introduction, persistence and spread of pathogens, as well as to protect animal and public health.
The main objective of implementing these measures is to reduce the risk of introducing and spreading diseases to, from or within:
• an animal population
• a unit, area, compartment, means of transport or any other facilities, premises or locations;

The key objectives of a biosecurity plan:

1. preventing the penetration of pathogens (exclusion of pathogens or external biosecurity)
2. reducing the penetration / spread of pathogens already existing among animals or other sections of the farm (biomanagement or internal biosecurity).
3. preventing the penetration / spread of pathogens existing in the farm to other non-infected farms / animals (e.g. biocontamination).
4. minimizing the incidence and spread of infections that impact the health of the population.

Biosecurity measures

I. Ensuring the farm perimeter:
II. The existence, operation and proper maintenance of the veterinary sanitary filter:
III. The proper maintenance of the facilities used for housing, feeding and watering animals;
IV. Feed supply;
V. Transporting live animals to and from the farm:
VI. Code of good practice and good hygiene practice
VII. Adhering to the technological principle “all-in, all-out” at the compartment/pen level.
