Scientists work to ‘potty train’ cattle
Researchers say the scheme could improve cow welfare and hygiene.
Toilet training could bring welfare and environmental benefits 

Scientists in New Zealand are working on a project to ‘potty train’ cattle, in a bid to improve welfare and reduce environmental impacts.

AgResearch New Zealand began by training eight calves, moving them to a ‘potty stall’ with a remote-controlled feeding station at one end.

Calves were rewarded for urinating or defecating in front of the feeding station. After six weeks and around 60 training sessions, the cows were given free access to the stalls and tested to see if they would use it.

Researchers say the scheme could improve cow welfare and hygiene in dairy sheds, giving farmers greater control over effluent application on pasture. This would offer significant environmental benefits, with reduced nitrogen loss on farms.

Dr Alison Vaughan, who carried out early trial work at the University of British Columbia, is working as a consultant on this project. During a 2017 TED Talk, she said an average cow produces around 15l of urine and 30kg of faeces a day.

“Because of this, barns are often designed to make removing manure easier to keep cows out of manure, but some of these designs and structures can compromise cow comfort and restrict behavioural freedom.”

Data from the recent study will be analysed over the coming months before the findings are published.

Pair of endangered Amur leopard cubs born at Colchester Zoo

News Story 1
 Keepers at Colchester Zoo are hailing the arrival of a pair of critically endangered Amur leopard cubs.

The cubs were born to first-time parents Esra and Crispin on the 9 September. This is the first time the Zoo has bred Amur leopard cubs on-site.

Amur leopards originate from the Russian Far East and north-east China. In the wild they are threatened by climate change, habitat loss, deforestation and the illegal wildlife trade.

The cubs are said to be “looking well” and are expected to emerge from their den in a few weeks.

BEVA survey seeks views about antibiotic use in horses

Equine vets are being invited to participate in a BEVA survey that aims to find out more about antimicrobial resistance in equine veterinary practice.

Designed by researchers at the University of Liverpool and incoming BEVA president Tim Mair, the survey aims to fill gaps in knowledge about how antimicrobials are being used in equine practice and the landscape of resistant infections encountered in equine practice.

Researchers hope the results will lead to a greater understanding of the role of antimicrobial treatment and antimicrobial resistance in horses and protect antibiotics for the future of equine and human health.
