259 Research paper – Wejden – 2019 – Modeling heat and Carbon Dioxide production of a broiler house at hourly time step

In Significant Impact Groups: Housing and welfare \ Climate
Species targeted: Poultry;
Age: Not stated;
Summary:
Models of heat production of broilers are used to design the thermal equipment to optimize climate control. The reference models are now around fifteen years old. Daily values of heat productions are deduced from the live weight of broilers and do not integrate the diversity of livestock systems and the genetic progress’s evolution. Animal welfare and environmental issues now require simulations at an hourly time step or even shorter. Our objective is to propose an hourly model of heat, carbon dioxide and water vapor productions incorporating the zoo technical parameters specific of a commercial batch of broilers. To update the reference equations, experiments were performed so that models replicated conditions similar to commercial farming. We propose a new model design for heat production. The perspectives are to apply this modeling to climate control and thermal design of broiler houses.

258 Research paper – Allimonnier – 2019 – Assessment of the innocuity and immunostimulant properties of plant extracts in chicken cell lines

In Significant Impact Groups: Specific alternatives \ Immunomodulators
Species targeted: Poultry;
Age: Not stated;
Summary:
The use of plant extracts in poultry feed is a promising approach to reinforce the animals’ natural defenses. However, this approach is limited by the lack of robust references and solid methodological bases. Our objective was to develop and test a simple, reliable and repeatable method to determine capacities of plant extracts in stimulating the natural defenses of poultry. A bibliographic study helped identifying 4 plant extracts: Astragalus, Echinacea, Ginseng and Melissa. We have shown that Astragalus, Echinacea, Ginseng and Melissa had little or no cytotoxic effects. Results from experiments with Melissa and Ginseng suggest these may have immune stimulating activities. The Melissa and Ginseng extracts appear to be non-cytotoxic candidates, capable of stimulating the natural defenses of poultry.

In Significant Impact Groups: Housing and welfare
Species targeted: Broilers; Poultry;
Age:
Summary:
This directive was produced for Dutch poultry veterinarians to provide guidance in veterinary practice concerning the start-up of and management in the first week of live of broiler chicks. Apart from the procedures to follow in prescribing antibiotic treatments the directive provides a vast amount of practical tips and norms for managing and monitoring the optimal start-up of broiler chicks. For example, regarding optimal climate, lighting scheme, water management, feed and supportive measures such as advice on pre- and probiotics, vitamins and minerals, organic acids and fytobiotics. So while this guide is directed to veterinarians and offers a lot of veterinary medicinal information regarding the risk for illness and pathogens and its treatment in the early life of broilers, it can also be an interesting information source for broilers farmers keen on finding insights to improve their start-up management.

256 ToolsChecklists – EMA Categorisation of antibiotics for use in animals for prudent and responsible use by European Medicines Agency

In Significant Impact Groups: Prudent use AB \ Veterinarian
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age:
Summary:
Veterinarians are encouraged to check and consider EMA’s updated scientific advice on the categorisation of antibiotics when prescribing these medicines for animals in their care. This categorisation can also be used as a tool for the preparation of treatment guidelines. The classification now comprises four categories, from A to D: Avoid, Restrict, Caution and Prudence. Category A: These medicines may not be used in food-producing animals and may be given to individual companion animals only under exceptional circumstances. Category B: The use of these medicines in animals should be restricted to mitigate the risk to public health. Category C: These antibiotics should only be used when there are no antimicrobial substances in Category D that would be clinically effective. Category D: These antibiotics can be used in animals in a prudent manner.

255 Research paper – Le Guenic – 2018 – Joining advising and innovative training in order to reduce antibiotic use in the dairy sector

In Significant Impact Groups: AMU reduction strategies \ Prudent use AB
Species targeted: Dairy;
Age: Not stated;
Summary:
A training-program involving virtual classes and personalized advice on farm has been evaluated by an exposed/non exposed study on two themes: control of clinical mastitis and implementation of selective dry cow therapy. Exposed farmers significantly improved their knowledge regarding intramammary infections and selective dry-cow therapy compared to non-exposed farmers. Those from the “control of clinical mastitis” group have decreased the use of antibiotics against mastitis during lactating and dry period from 4 days/year/cow of antibiotic treatment to 3.1. Main messages are : precise knowledge on the role of antibiotics at drying-off, mastering use of a teatseal, respect of low cellular thresholds to sort the cows out.

254 Industry Innovation – Cow bath by Timmerman

In Significant Impact Groups: Specific alternatives \ Other
Species targeted: Dairy;
Age: Adult;
Summary:
Cows that are stranded on the ground as a result of milk fever, a heavy birth or a fall are helped back into their legs with the use of a warm bath. Water helps the cow to get up because they only weigh 30 percent of their own weight. Muscles are relieved, the pressure decreases and the blood circulation improves. The cow bath is brought to the location together with a tank of hot water. The cow is placed on a mat and pushed into the bath. Then the watertight doors are attached and the water tap opens. The water is 38 degrees and the cow stays in the bath for six hours. The halter is tied so that the cow does not drown. The cow usually stands immediately.

253 Industry Innovation – in case of heat feed more often and clean boxes by Gezondheidsdienst voor Dieren (GD)

In Significant Impact Groups: Feed / gut health \ Feeding management; Housing and welfare
Species targeted: Dairy;
Age: Adult;
Summary:
A cow can suffer from heat stress from 21 degrees. To prevent this, dairy farmers should not feed at the hottest time of the day, according to the Gezondheidsdienst voor Dieren (NL). To keep the feed tasty and fresh, it is advisable to provide fresh feed several times a day (at least twice) and to (mechanically) ventilate the barn well over the feed alley. In order to prevent rumen acidification, which occurs more often in heat, a buffer can be added in consultation with the feed supplier in order to maintain the acidity level in the rumen. Bring the cows inside at the hottest time of the day and make sure there is unlimited water available. Clean cubicles are also necessary in case of heat. Bacteria in cubicles thrive in the heat and grow exponentially. There is then an increased risk of Kiebsiella mastitis. Therefore clean the cubicles extra often.

250 ToolsChecklists – Welzijnscheck by POV

In Significant Impact Groups: Housing and welfare
Species targeted: Pigs;
Summary:
Since mid-June 2020, welfare checks for sucking piglets, weaned piglets, fattening pigs and rearing sows have been available on www.welzijnscheckvarkens.nl. They show the risks of welfare problems on the farm per animal category.
This concerns in particular the risk assessment of the biting behaviour of pigs. The indicators (animal-bound and non-animal-bound) that influence the bite behaviour are assessed. The aim of the risk assessment is to improve animal welfare, animal health and overall operating results.
Purchasers in the Netherlands and abroad place high demands on the animal welfare of pigs. The welfare check for pigs has been developed to demonstrate good animal welfare. It also enables pig farmers to properly identify the risk of biting their pigs’ flanks, ears or tails.
