New technology to reduce number of chickens used in research
"Discovering a way to easily freeze avian reproductive cells and subsequently bring back a genetically diverse flock will help the preservation of endangered breeds of poultry".
Surrogacy method to support the creation of a new chicken biobank.

Scientists at the University of Edinburgh are seeking to develop new technology that will limit the number of chickens used in research.

The approach involves freezing chicken reproductive cells and using sterile surrogates to hatch the required breeds. Researchers say this will ultimately support the formation of a new biobank, maintain genetic diversity and prevent problems with inbreeding.

The project is being conducted by researchers at The Roslin Institute and is being funded by the National Centre for the Replacement Refinement and Reduction of Animals in Research (NC3Rs).

Dr Mike McGrew from the Roslin Institute said: “Discovering a way to easily freeze avian reproductive cells and subsequently bring back a genetically diverse flock will help the preservation of endangered breeds of poultry, increase food security from disease outbreaks and reduce the numbers of animals used in research.”

In the project, researchers aim to optimise how to freeze reproductive cells by studying three breeds of chicken currently used in research. They then hope to demonstrate that a single, surrogate chicken can lay eggs that come from many individual donor birds.

Scientists say this will validate the creation of biobanks for flocks of poultry for research purposes, which will limit the number of animals bred for use in this way. The novel method could also help to preserve rare chicken breeds.

World Bee Day celebrations begin

News Story 1
 Today (20 May) marks the fifth annual World Bee Day, which raises awareness of the importance of bees and pollinators to people and the planet. Observed on the anniversary of pioneering Slovenian beekeeper Anton Jana's birthday, this year's celebration is themed: 'Bee Engaged: Celebrating the diversity of bees and beekeeping systems'.

Organisations and people celebrating the day will raise awareness of the accelerated decline in pollinator diversity, and highlight the importance of sustainable beekeeping systems and a wide variety of bees. Slovenia, the initiator of World Bee Day, will be focusing on teaching young people about the significance of pollinators.

Further avian flu cases confirmed

Three cases of highly pathogenic avian influenza (HPAI) H5N1 have been confirmed in recent days, bringing the total number of cases in England to 98.

On Thursday, the APHA confirmed two cases of HPAI H5N1 near Redgrave, Mid Suffolk and Market Weston, West Suffolk. A case H5N1 was also confirmed in poultry at a premises near Southwell, Newark and Sherwood, Nottinghamshire.

Protection and surveillance zones are in place around the affected premises. Further details are available at gov.uk
