New embryo identification IVF method in Cattle discovered
The breakthrough is set to reduce pregnancy issues in cows.
The new method is 'set to boost' the dairy industry.

Researchers from the University of Kent, the University of Nottingham and L'Alliance Boviteq Inc have established a method of significantly improving in-vitro fertilization in cattle.

Advanced programmes have been able to identify embryos with traits including disease resistance, food conversion and improved meat and milk production.

The researchers discovered a new way to identify a subset of embryos that rarely lead to a live birth – those with a less than 5 per cent chance – due to carrying chromosome disorders. The study found that this process improved overall pregnancy rates in cattle by 7.8 per cent after analysing 1,713 embryos.  

It is thought that this new research could inform future treatment in fertility clinics for humans, with preimplantation genetic testing for aneuploidy being one of the most debated areas of reproductive medicine in humans.

Professor Darren Griffin, senior author of the paper and professor of genetics at the University of Kent, told the University of Kent News Centre: “This new PGT-A method of embryo identification will be an enormous boost for the cattle production industry and will also be the platform for further research into this vital science, for which we anticipate seeing the benefits especially in fertility clinics.”

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

UK's BSE risk status downgraded

The WOAH has downgraded the UK's international risk status for BSE to 'negligible'.

Defra says that the UK's improved risk status recognises the reputation for having the highest standards for biosecurity. It adds that it demonstrates decades of rigorous animal control.

Outbreaks of Bovine Spongiform Encephalopathy, also known as mad cow disease, have previously resulted in bans on Britain's beef exports.

The UK's new status could lead to expanded trade and better confidence in British beef.

Christine Middlemiss, the UK's chief veterinary officer, said: "WOAH's recognition of the UK as negligible risk for BSE is a significant milestone and is a testament to the UK's strong biosecurity measures and the hard work and vigilance of farmers and livestock keepers across the country who have all played their part in managing the spread of this disease.
