Lame sheep adjust their behaviour to reduce discomfort, study finds
Best practice for lameness relies on fast treatment, but currently no validated commercial tools exist to help with diagnosis.

New sensing technology could improve sheep health

A study from the University of Nottingham’s School of Veterinary Medicine and Science has shown that lame sheep will adjust how they carry out certain activities, such as walking, standing or lying down, rather than reducing the amount of activity.

The study used a new prototype tagging and monitoring system, developed by Dr Jasmeet Kaler, associate professor in epidemiology and farm animal health, along with companies Intel and Farm Wizard. The technology is worn on a sheep’s ear tag and gathers accelerometer and gyroscope data to track the animal’s behaviour and movement.

Detecting lameness has previously been difficult as it relies on visual inspection. Researchers were not only able to detect the features of lameness using the new technology, they also identified behaviours which are far more difficult to spot with the human eye.

When walking, the main characteristics of lameness were frequency, linked to rhythm and pace, researchers say this could be the result of reduced mobility in lame sheep, leading to changes in acceleration and rotational movement.

There was also a change in the gait of lame sheep, with ‘peculiar head nodding’ in line with their stride, compared to smoother stride patterns in non-lame sheep.

According to the report, the results for classification of lameness had a higher accuracy within lying and standing activities.

The most notable features include a mixture of frequency and time-domain features, suggesting differences in the variability and smoothness of movements for both standing and lying down between lame and non-lame sheep that may be attempting to alleviate pain caused by the lameness.

Commenting on the results of the study, Dr Kaler said: “This has been the first report of its kind and given lameness classification is possible within all these activities this helps to improve the accuracy as well as flexibility in terms of energy requirements. This automated system for the lameness detection can help improve sheep health and welfare on farms.”

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
