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.

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.

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.

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.

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.

Species targeted: Poultry;
Age: Young;
Summary:
The robustness of day-old chicks is a crucial parameter to optimize welfare, to limit their mortality, and to reduce the use of antibiotics. The age of the breeders and the time at the hatchery can have a negative impact on their robustness. The aim of this study was to test optimized environmental conditions during a prolonged wait (24 hours) before breeding of two sets of day-old chicks from breeders at the beginning of laying (DP) and at the end of laying (FP). Results show that chicks placed in cases of lower density, in controlled environment, and with empty space between each box to improve air circulation significantly have less in weight loss between hatching and arrival at the farm, a significant increase in weight at D12 in FPs, a cloacal temperature greater at D1, and at slaughter a higher breast yield.

In Significant Impact Groups: Specific alternatives \ Other Biosecurity
Species targeted: Poultry;
Age: Young;
Summary:
During cooling of freshly laid eggs, the porosity of the eggshell allows environmental microorganisms to penetrate the egg and it is a cause of poor health for chicks’. The presence of microorganisms on the shell, the time between laying and collection, and storage conditions of eggs can increase risk of contamination. The disinfection of hatching eggs is an effective way of prevention, but it is done several hours after laying, with some risk of bacterial proliferation. Therefore it is important to reduce the contamination of the eggs after laying and before their introduction in the hatching process. Several assays to test alternative practices to reduce bacterial contamination were done. Using air disinfection systems in the egg conveyor didn’t lead to decrease bacterial contamination on egg surface. However, quick isolation of freshly laid eggs from the rearing area led to a significant decrease of outer- and inner-shell bacterial contamination.

269 Research paper – Piel – 2017 – Software for monitoring of antibiotics consumptions in poultry breeding

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Poultry;
Age: Not stated;
Summary:
In the context of reasonable use of antibiotics, monitoring consumption is an indispensable step to have a better knowledge of practices, consumption levels in order to implement improvement actions and evaluate them. In this perspective, software for consumptions monitoring has been developed by the company DBM. It is an innovative follow-up tool that helps the breeder in an animal health sustainable management approach. This software can be used by the breeder and the veterinarian: it measures and assesses joint actions set up to reduce the use of antibiotics, compares the evolutions by production, sectors or breeders in relation to the results of all livestock monitored and also to reference indicators. For the breeder and his veterinarian, the software is a tool that enables a reactive “diagnosis” and that helps to make a decision. The software shows the efforts carried out by the breeders and veterinarians to their partners and networks.

In Significant Impact Groups: Housing and welfare \ Weaning age and management; AMU reduction strategies
Species targeted: Poultry;
Age: Young;
Summary:
Early rearing phase represents a key period in breeding and requires special technical and sanitary management to ensure the competitiveness of poultry production and welfare. 30 Label Rouge poultry flocks were sampled. Data on the environment, feeding, watering, cleaning and disinfection management, body weight and body condition monitoring were collected and a questionnaire was also sent to the farmer to identify its practices. The selected variables of interest, were: weight, homogeneity of the batch, rate of pododermatitis, mortality and welfare rating at 15 days. From the study it was found that the origin of the chicks had a significant impact on the weight, the homogeneity of the batch and the mortality at 15 days. Access to specific start-up feeding equipment also appears to influence the weight, homogeneity and rate of pododermatitis at the end of the start. This rate is also influenced by the quality of the litter in breeding.

In Significant Impact Groups: Specific alternatives \ Pre-/probiotics Feed / gut health
Species targeted: Poultry;
Age: Young;
Summary:
Reducing the use of antibiotics is a major challenge for the poultry sector. This work aims at assessing the efficiency of several different forms of food additive on technical performances and health status of Label Rouge broilers, produced in sub-optimal conditions (eggs storage before incubation for 18 days and distribution of less digestive food with essential amino-acid deficiency). The effects of pre-starter, rehydrating, and combination of the two products are tested for the first two days of rearing. The (day-old) chick quality, measured according to 8 criteria, is negatively impacted by the storage duration before incubation. For the first 2 days, the pre starter effect is positive. Its usefulness is clear when this is combined with the rehydrating association. The supplementation from 7 to 12 days has improved the broiler feed efficiency. For the second part of rearing (15-76 days), technical results are not significantly different regardless of treatments.
