Horses 'can communicate their preferences with humans'
Horses preferred to remain without a blanket in nice weather, but to have a blanket on in wet, windy or cold weather.
Study finds horses can indicate whether they want a blanket on or off

A new study suggests horses can learn to communicate with humans by touching different symbols to indicate whether they want a blanket on or off.

Reward based operant conditioning was used to teach a group of horses to approach and touch a board, and to understand symbols on three boards, which indicated either 'no change', 'blanket off' or 'blanket on'.

Scientists from the Norwegian Veterinary Institute found that horses preferred to remain without a blanket in nice weather, but to have a blanket on in wet, windy or cold weather.

When 22 horses were tested on one of two sunny days (20-23ºC) all 10 wearing the blanket touched the 'blanket off' board. The remaining 12 who did not have a blanket on touched the board meaning 'no change'.

The same 22 horses were tested again in colder weather (5-9ºC). In these conditions, all 10 wearing the blanket indicated 'no change' while 10 that were not wearing a blanket touched the 'blanket on' board and the remaining two without a blanket indicated 'no change'. However, the same two gave the 'blanket on' signal on two different test days when temperatures were -12ºC and 1ºC with sleet respectively.

Writing in the journal Applied Animal Behaviour Science, researchers summarised the findings: 'Horses chose to stay without a blanket in nice weather, and they chose to have a blanket on when the weather was wet, windy and cold. This indicates that horses both had an understanding of the consequence of their choice on their own thermal comfort, and that they successfully had learned to communicate their preference by using the symbols.'

The team believe their novel method could pave the way for further research on horse preferences regarding management and training routines.

Bristol uni celebrates 75 years of teaching vets

News Story 1
 The University of Bristol's veterinary school is celebrating 75 years of educating veterinary students.

Since the first group of students were admitted in October 1949, the school has seen more than 5,000 veterinary students graduate.

Professor Jeremy Tavare, pro vice-chancellor and executive dean for the Faculty of Health and Life Sciences, said: "I'm delighted to be celebrating Bristol Veterinary School's 75 years.

"Its excellence in teaching and research has resulted in greater understanding and some real-world changes benefiting the health and welfare of both animals and humans, which is testament to the school's remarkable staff, students and graduates."

Second edition of BSAVA's Thoracic Imaging manual released

The British Small Animal Veterinary Association (BSAVA) has released the second edition of the BSAVA Manual of Canine and Feline Thoracic Imaging.

This edition provides new knowledge, gathered from CTs and MRIs, some of which can be applied to radiographic interpretation.

The first section explores different imaging modalities for thoracic imaging, including recommended uses. The second section illustrates features of normalcy and disease in the main anatomic compartment of the thorax.

This includes structured information about thoracic imaging interpretation and individual body systems.

There is also a new chapter exploring how artificial intelligence could be applied to the practice.

Tobias Schwarz and Peter Scrivani, who edited the book, said: "We are grateful to the many radiologists and other specialists from around the world who contributed to this manual by writing chapters, supplying images, and providing feedback.

"Our aim was to ensure that the manual was as up-to-date, accurate and comprehensive as possible."

Print copies can be purchased in the BSAVA store, with a digital version in the BSAVA library.
