  2. Ultrasonographic examination of equine fetal growth parameters throughout gestation in pony for Equine-Assisted Therapy

    Full-text: Available

    | Contributor(s):: Gao, Y., Hannan, M. A., Murata, K., Rajabi-Toustani, R., Nambo, Y.

    Equine-Assisted Therapy (EAT) is gaining popularity. Ultrasound examination is used to decrease the abortion rate in horses. In this study, to monitor fetal well-being throughout the gestation for EAT, we measured fetal heart rate (FHR), fetal eye orbit (FEO), fetal gonad length (FGL), fetal...

  3. The effects of cage color and light intensity on rat affect during heterospecific play

    | Contributor(s):: LaFollette, Megan R., Swan, Melissa P., Smith, Rebecca K., Hickman, Debra L., Gaskill, Brianna N.

  4. Can dolphins heal by ultrasound?

    | Contributor(s):: Brensing, K., Linke, K., Todt, D.

  5. Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?

    | Contributor(s):: Burwell, A. K., Baldwin, A. L.

    In animal facilities, noises, often poorly controlled, occur over a wide range of frequencies and intensities. Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology, but it is not known how they affect the autonomic nervous system (ANS). This study...

  6. Ultrasound observations of fetal movements in the pig: an exploratory study

    | Contributor(s):: Cohen, S., Mulder, E. J. H., Oord, H. A. van, Jonker, F. H., Weijden, G. C. van der, Taverne, M. A. M.

    The feasibility and practical conditions of repeated, non-invasive ultrasound scanning for fetal movements during late gestation in the pig were studied. After a short training period of the sow, good quality recordings of fetal movements were obtained for 60 min using a 3.5 MHz ultrasound...

  7. Foetal behaviour and the possibility of its detection in farm animals

    | Contributor(s):: Bielanski, A.

    Foetal behaviour in terms of various foetal activities and bodily functions as well as methods of observation of that in farm animals are briefly reviewed with respect to their practical usefulness and limitations. Emphasis is given to the foetal heart and kinetic activity as the first functions...

  8. Some features of an ultrasonic study of bovine foetal kinesis

    | Contributor(s):: Fraser, A. F.

    Following the use of doppler ultrasound to study equine foetal kinesis, further observations on this form of behaviour have been made on bovine subjects using similar apparatus. Pregnant cows were examined with an intrapelvic transducer probe introduced per rectum and directed over the dorsum of...

  9. The efficacy of an ultrasonic cat deterrent

    | Contributor(s):: Nelson, S. H., Evans, A. D., Bradbury, R. B.

    Ultrasound deterrents for a variety of mammals, including cats, are widely available in the commercial market, but few have been independently tested for efficacy. This study tested the efficacy of an ultrasonic cat deterrent 'Catwatch copyright ', using 63 and 96 volunteer observers in two...

  10. A note on behavioural responses of farm animals to ultrasound

    | Contributor(s):: Algers, B.

    Horses, cattle, swine, sheep and poultry all reacted to ultrasound from a device used to clear rats from buildings. Most animals were drawn towards the sound at first and then turned away and kept their ears pointing away from the sound. Poultry showed the least reaction. The device is considered...

  11. Aversive responses of dogs to ultrasonic, sonic and flashing light units

    | Contributor(s):: Blackshaw, J. K., Cook, G. E., Harding, P., Day, C., Bates, W., Rose, J., Bramham, D.

    Two experiments were conducted to test the ability of various ultrasonic devices to repel dogs at a distance of 1 m. In experiment 1, three ultrasonic devices (Unit 1, a commercial unit with bursts from 14 to 42 kHz and overall sound pressure of 60 dB; Unit 2 had bursts of 7-15, 25-30, 26-35 and...
