dc.description.abstract
Efficient estrus detection in high-producing dairy cows is a permanent
challenge for successful reproductive performance. In former studies, dogs
have been trained to identify estrus-specific odor in vaginal fluid, milk,
urine, and blood samples under laboratory conditions with an accuracy of more
than 80%. For on-farm utilization of estrus-detection dogs it would be
beneficial in terms of hygiene and safety if dogs could identify cows from the
feed alley. The objective of this proof of concept study was to test if dogs
can be trained to detect estrus-specific scent in saliva of cows. Saliva
samples were collected from cows in estrus and diestrus. Thirteen dogs of
various breeds and both sexes were trained in this study. Five dogs had no
experience in scent detection, whereas 8 dogs had been formerly trained for
detection of narcotics or cancer. In the training and test situation, dogs had
to detect 1 positive out of 4 samples. Dog training was based on positive
reinforcement and dogs were rewarded with a clicker and food for indicating
saliva samples of cows in estrus. A false indication was ignored and
documented in the test situation. Dogs with and without prior training were
trained for 1 and 5 d, respectively. For determining the accuracy of
detection, the position of the positive sample was unknown to the dog handler,
to avoid hidden cues to the dog. The overall percentage of correct positive
indications was 57.6% (175/304), with a range from 40 (1 dog) to 75% (3 dogs).
To our knowledge, this is the first indication that dogs are able to detect
estrus-specific scent in saliva of cows.
