When research meets farming to lift welfare (article in Poultry World, dd 12-6-2018).
The EU-funded Hennovation project was an exercise in bringing egg farmers together with researchers to develop practical ways to improve welfare, as Tony McDougal discovers.
Researchers have partnered with farmers to draw up practical new measures for improving the health and welfare of farmed poultry.
The 2 ½ year EU-funded Hennovation project, which ended this autumn, has been finding ways to introduce practice-led innovation in sustainable animal welfare through the development of innovation networks.

The battle against red mites
By Marleen Teuling, Poultry World, Oct. 13, 2017.
Controlling red mite is an emerging issue of great significance to the global egg industry. But it is also an underestimated problem by many poultry producers, who aren’t always aware of the full impact of a red mite infestation. Here’s an insight into the consequences.

Challenges and solutions in coping with poultry red mite
Delegates at the International Egg Commission’s conference in Bruges were given an update on the spread of poultry red mite, the ongoing scientific work and solutions to controlling outbreaks.

From the article:
Poultry red mite (PRM) is widespread across Europe, the Middle East and the Far East. Only North America is currently free from mite.
PRM thrives in high temperatures and high humidity and has a life cycle of between 7-17 days.
It led birds to become restless at night, caused skin and feather irritation, could lead to feather pecking and cannibalism and disturbed the egg function at night. In moderate to severe cases, it led to anaemia, weight loss and immune-suppression.
They can survive without a single meal for a year or longer and can tolerate temperatures of up to 45°C and below -25°C.
The total annual cost of poultry med mite infestations in the European egg laying industry is estimated to be €231m and €3.2bn worldwide.
Integrated pest management is the way forward in tackling the mite.
Hennovation: “Practice lead innovation supported by science and market-driven actors in the laying hen and other livestock sectors”
The Hennovation project demonstrated the potential of innovation led by producers and industry (on-farm, during transport and at the abattoir) through the establishment of innovation networks that proactively searched for and utilized new ideas to make their business more efficient and sustainable. The networks initially tackle two particular issues of concern in the production chain: injurious pecking and the transport and use of end-of-lay hens. 19 innovation networks were mobilized at different levels of the production chain, local, national and European level in five countries (United Kingdom, Sweden, The Netherlands, Spain and The Czech Republic) These networks were supported by science driven-actors, such as veterinary surgeons, farm advisors and scientific researchers, and market-driven actors, such as those that buy eggs e.g. retailers, packers, food processors, and those certifying egg production e.g. farm assurance companies and certification schemes.
The on-farm networks, 15 in total, focussed on various aspects that are known to have influence on injurious pecking. Injurious pecking is a problem that has many risk factors and the networks tested a variety of innovative ideas. The off-farm networks, four in total, focussed on various aspects that are relevant for catching and transport of End-of-Lay hens.
Alongside product or technical innovation (e.g. new design of trolleys for depopulation, new type of litter material to reduce stress and encourage natural behaviour or the use of alpacas in organic systems to reduce predation), a variety of often less expected and sometimes unintended ‘soft’ innovations also emerged through these networks. These were related to protocol or process (e.g. a new way of monitoring Poultry Red Mite infestation and new relationships between production chain actors, for example the pullet rearers).
Based on the innovative ideas tested by the innovation networks 38 Practice Abstracts and an additional five technical notes were developed by the network facilitators for use in practice by end-users.

We’ve updated our description on poultry red mite, and added a checklist in English as well as a more elaborated description of integrated pest management of poultry red mite, intended to reduce the need for chemical treatments through monitoring of the red-mite population. Descriptions are available in Dutch and in English. For more information in Dutch see also here.

A Dutch survey on poultry red mite, which has also been conducted throughout Europe, showed the following results:
At around 80% of the laying-hen farms, red mites were seen. 32% of the
participating farms were able to find the red mites in cracks and crevices; a mild to moderate contamination. At 27% of the farms groups or clusters of mites were visible on the housing system, indicating a serious infection. Main treatments used against red mites were silica products and soaps. Most laying-hen farmers saw a decrease in the number of red mites after treatment, although only 14% of the respondents monitored the red-mite population. Treatments are especially applied when (the first) red mites are visible. Hygiene measures against red mites are mainly taken when the house does not contain laying hens. On average, poultry farmers spent € 0.15 / hen / production period of 73 weeks (min-max; € 0.0005 – € 0.67). It is not possible to draw firm conclusions based on this survey because only 44 farmers responded, i.e. 5% of the total number of Dutch layer farms

Webinar series Hennovation
Webinar 1: Possibilities to control Poultry Red Mites
Hennovation is a project supporting practice led innovation in the laying hen sector. Groups of farmers, the so called networks, addressed various problems related to feather pecking in laying hens and end-of-lay hens. In total 19 networks were active. Four networks focused on Poultry Red Mites.
The live webinar on ‘Possibilities to control Poultry Red Mites’ took place on Thursday 29 June 2017.
