281 Research paper – Popescu – 2010 – Relationship Between Barn Hygiene and Lameness Prevalence in Thirty- Five Transylvanian Dairy Farms

In Significant Impact Groups: Biosecurity \ Pathogen management
Species targeted: Dairy;
Age: Not stated;
Summary:
This study focuses on the relationship between hygiene and lameness prevalence in dairy cattle kept in tie-stall barns in Transylvania (Romania). The barns’ hygiene was assessed based on the body hygiene of the housed cattle. The prevalence of lameness was determined and the cleanliness of the two body areas of the cows in 35 dairy farms with tie-stall housing. A total of 2028 dairy cows were evaluated. The percentage of hygiene scores of 3 and 4 for the upper leg and flank was on average 41% and for the lower leg on average 33%, with significant differences between the hygiene of the two body areas. They found an association between leg hygiene and lameness, both with respect to lower leg hygiene and upper leg and flank hygiene. The obtained results showed that the poor hygiene of barn represents a risk factor associated to lameness prevalence in tied dairy cattle.

280 Research paper – Pasca – 2017 – Medicinal Plants Based Products Tested on Pathogens Isolated from Mastitis Milk

In Significant Impact Groups: Specific alternatives \ New antibiotics
Species targeted: Dairy;
Age: Adult;
Summary:
The search for alternative drugs based on plants has become a priority in livestock medicine. In this context, the main objective of this study was to determine the antimicrobial effect of extracts and products of several plants on pathogens isolated from bovine mastitis. A total of eleven plant alcoholic extracts and eight plant-derived products were tested against 32 microorganisms from milk. The obtained results have shown an inhibition of bacterial growth for all tested plants, with better results for Evernia prunastri, Artemisia absinthium, and Lavandula angustifolia. Moreover, E. prunastri, Populus nigra, and L. angustifolia presented small averages of minimum inhibitory and bactericidal concentrations. Among the plant-derived products, three out of eight have shown a strong anti-microbial effect comparable with the effect of florfenicol and enrofloxacin. These results suggest an important anti-microbial effect of these products on pathogens isolated from bovine mastitis with a possible applicability in this disease.

279 Research paper – Nadas – 2016 – Antimicrobial Susceptibility Profile of Microbial Pathogens Isolated From Calves With Respiratory Diseases

In Significant Impact Groups: Pathogen management \ Managing sick animals; Targeted use of antibiotics
Species targeted: Dairy; Beef;
Age: Young;
Summary:
Respiratory disease are frequent in calves due to the weaning stress, transport and environmental changes. The aim of this study was isolate bacteria from 30 calves with respiratory disorders and test their antimicrobial susceptibility. Samples were collected from calves with respiratory disorders (nasal discharge) aged 6 to 9 weeks in 2 series, using sterile swabs. The study carried out on nasal discharge samples collected from calves with respiratory disorders and their antimicrobial profile testing led to the following conclusions: 1) Low susceptibility to Florfenicol is caused by previous treatments when this molecule was excessively used and without prior sensitivity testing. 2) Cefquinome may represent an emergency therapeutic antibiotic for respiratory infections in calves, but the administration should always be preceded by susceptibility testing of the isolates.

278 Research paper – Maciuc – 2015 – A New Software Programme for Data Management in Dairy Farms

In Significant Impact Groups: Precision Livestock Farming & Early detection \
Species targeted: Dairy;
Age: Not stated;
Summary:
The current paper presents the original results regarding a software programme for production and reproduction data management in dairy farms, used also in the accounting department and in the genetic breeding of bovine herds. A management system database – SGBD – which assures the independence of logical correlations between dates and their minimum redundancy – was used for this purpose. This provided a fast development and a cost-effective use of application programmes for data exploring from a complex structure and also fast access to the dates, providing them a very good security. Therefore, SGBD is an assembly of programmes which allow the users to interact with a database, designed for large amounts of information, whose management requires not only a rigorous structure but also a rational access and processing. The programme called “C.O.P & R.G” addresses farmers and units dealing with accounting and improving the milk production of dairy cattle.

Species targeted: Dairy;
Age: Not stated;
Summary:
Definitions and importance of animal welfare are presented in this article. Among one of the definitions presented is that animal welfare is “the degree to which the requirements for physical, behavioral and psychological needs of the animal are satisfied.” Also for animals that are dependent on humans, animal welfare also entails the so-called five freedoms simultaneously: 1- ensuring access to fresh water and food; 2-ensure appropriate environment, including watering and comfort; 3- prevention of pain, injury, rapid diagnosis and treatment of wounds; 4- elimination of fear and mental suffering; 5- providing space, facilities and the company of other animals to express normal behavior. The concept of animal welfare must be made common knowledge to all the employees in the farm. The idea that animal welfare depends on their behavior and their behavior towards animals may induce or prevent fear response and undesirable emotional state should be transmitted and understood.

Summary:
Bovine mastitis is a major disease affecting dairy cattle worldwide. The milk collected from cows with different type of inflammation, including mastitis, is characterized by an increased number of somatic cells (SCC). The aim of this study was to evaluate the antioxidant/oxidant status in normal cow’s milk and in subclinical mastitis milk using three parameters: total antioxidant status (TAS); levels of malondialdehyde (MDA); and levels of proteins (DNPH). Subclinical mastitis was diagnosed using an electrical conductivity method and by SCC in milk. Comparative analysis of TAS showed this parameter was on average significantly lower for mastitis milk samples. The results describing the antioxidant status were correlated with those on lipid and protein oxidative degradation. The average level of MDA in mastitis milk was higher compared with normal milk. The levels of SCC, MDA, and DNPH were significantly higher in subclinical mastitis milk compared to milk from healthy cows.

275 Research paper – Rousset – 2019 – Water management practices in rabbit and poultry farms improve understanding of different attitudes

Water \ Water quality
Species targeted: Poultry; Other;
Age: Not stated;
Summary:
In poultry and rabbit farms, the control of water quality is an important animal health measure. Technical guides describe good water management practices, and criteria of water quality. However, the level of receptivity and application of theses advices is very different between breeders. In order to sensitize farmers effectively, a qualitative study was conducted with 11 rabbit farmers and 7 broilers farmers, to improve understanding of different attitudes to water management practices. The majority of breeders define the quality of water in an imprecise way. Four profiles have been identified that can be represented along two axes: the level of knowledge and the level awareness of the importance of water quality subject. Breeders require advices that are more personal. It will be necessary to encourage them, to guide them more. Based on these profiles, suitable supports are being built.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Poultry;
Age: Not stated;
Summary:
Currently poultry production organizations are committed to defining an indicator monitoring the reasoned use of antibiotics. That is why, the French Poultry Institute (ITAVI), with the French poultry’s inter-professional organizations and Anses formalize a professional network to collect computerized data on use of antibiotics at farm level (RefA²vi project). In 2014 and 2015, two surveys allowed collecting data from poultry farms in all species and production types. The partners were invited to create a scheme of network organization, which have been tested during a pilot phase.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use; Prudent use AB
Species targeted: Poultry;
Age: Not stated;
Summary:
In order to improve the characterization of the influence of the human factor on the variability of antimicrobial uses, a survey was conducted in 2016 with 68 broiler breeders in the Brittany and Pays de la Loire regions. The use of antimicrobials, or at least the perception of the level of use by farmers (up or down), is directly related to the perception of their profession (positive or negative). The perception of the poultry profession also seems to be linked to the observance of certain health prevention practices. Finally, a positive view of the profession seems to be associated with farmers who have an easier time taking a step back from the health events (animal mortality) and the use of antibiotic treatments. The sensitization of technical teams, from their initial training, to take these factors into account appears essential, to help them reflect on the practice of their future profession.

In Significant Impact Groups: Housing and welfare \ Weaning age and management; AMU reduction strategies
Species targeted: Poultry;
Age: Young;
Summary:
The first 10 days of poultry rearing are a critical period for the chick development. A study was conducted to identify the early postnatal rearing conditions of broilers influencing antibiotic use and mortality in the first 10 days. 50 broilers flocks were investigated in Brittany. Visits were conducted 24 hours after the arrival of the chicks (V1) and 3 days later (V2). The average mortality rate was 1.9%, and 47 % of the flocks received antibiotic treatment. Data analysis revealed that flocks with a mortality rate higher than the overall flocks (2.3 %), were frequently treated with antibiotics (58 % of the flocks), were characterized by presence of E. coli in chicks in V1 and lameness in V2 chicks, generally had higher concentrations of CO2 in V1 (> 3 000 ppm), were located further from the hatchery (> 200 km) and did not use detergent to wash the poultry house.
