  1. Do Ferrets Perceive Relative Pitch?

  2. Development of frequency modulated vocalizations in big brown bat pups

    Contributor(s):: Heather W. Mayberry, Dr. Paul A. Faure (adviser)

    Developing bat pups produce distinct vocalizations called isolation calls (I‐calls) that serve to attract the bat's mother. Mothers use spatial memory, auditory and olfactory cues to reunite with their offspring. Because I‐calls are unique to individual pups, vocalizations are crucial for the...

  3. Sources and frequency of use of pet health information and level of confidence in information accuracy, as reported by owners visiting small animal veterinary practices

    Contributor(s):: Kogan, L. R., Goldwaser, G., Stewart, S. M., Schoenfeld-Tacher, R.

  4. Voluntary automatic milking in combination with grazing of dairy cows. Milking frequency and effects on behaviour

    Contributor(s):: Ketelaar-de Lauwere, C. C., Ipema, A. H., Ouwerkerk, E. N. J. van, Hendriks, M. M. W. B., Metz, J. H. M., Noordhuizen, J. P. T. M., Schouten, W. G. P.

    Grazing was combined with a fully automatic milking system (AMS) for a group of 24 crossbred Holstein cows. It was assumed that the cows would visit the AMS voluntarily. Zero grazing (G0) was compared with restricted grazing (cows could spend up to 12 h outdoors daily; G12) and unrestricted...

  5. Mating activity and its relationship to reproductive performance in Merino sheep

    Contributor(s):: Fowler, D. G.

    Mating activity was observed in 22 flocks at 5 locations; each flock was joined with rams under paddock conditions. In the 1st series of observations, on 16 flocks at 5 locations, the sum of interservice intervals for all ewes during an observation period (T) was highly correlated ( more than or...

  6. Observations on the nursing behaviour of beef cows suckling Charolais cross calves

    Contributor(s):: Somerville, S. H., Lowman, B. G.

    Three separate 48 h observations were made of the suckling behaviour of (1) Hereford X Friesian cows under grazing conditions, (2) Blue Grey cows under grazing conditions, and (3) Blue Grey cows housed. All the cows suckled Charolais cross calves. The mean suckling frequencies recorded were 5.5,...

  7. Sexual responses of pullets to selection for mating behavior in male chickens

    Contributor(s):: Siegel, P. B., Cook, W. T.

    Bidirectional selection for number of completed matings in cockerels resulted in lines differing in male sexual behaviour. No correlated responses, however, were observed in the sexual behaviour of S12, S13 and S14 generation pullets. The sexual behaviour of females was measured as courtings...

  8. The relationship of male-male mounting to mate choice and sexual performance in male dairy goats

    Contributor(s):: Price, E. O., Smith, V. M.

    14 Alpine, 4 Lamancha, 7 Saanen and 6 Toggenburg [male][male], aged 1.5-4 yr, were observed for the incidence of mounting other [male][male] in their home enclosure, and were tested for choice of mate and mounting performance when exposed to [male] and [female] stimulus animals. 24 of the 31...

  9. Stimuli-related variation in urination frequency of female white-tailed deer during the estrous cycle

    Contributor(s):: Gassett, J. W., Osborn, D. A., Rickard, J. K., Marchinton, R. L., Miller, K. V.

    Variations in urination frequency of female white-tailed deer (Odocoileus virginianus) that appeared to be dependent on stage of the oestrous cycle and type of disturbance stimuli were observed, and possible causes for this potential chemosensory behaviour were evaluated. Eight does were exposed...

  10. The influence of mating conditions on the sexual behaviour of male and female pigs

    Contributor(s):: Hemsworth, P. H., Hansen, C., Winfield, C. G.

    Sixteen boars, aged 7 months, and 48 ovariectomised gilts, aged 7 months, were randomly allotted to mating in the boar's accommodation pen (boar pen treatment) or in an octagonal mating pen (mating pen treatment). One of 2 groups of gilts was induced into behavioural oestrus on alternate wk...

  11. Vocal individuality during suckling in the intensively housed domestic pig

    Contributor(s):: Blackshaw, J. K., Jones, D. N., Thomas, F. J.

    Nursing vocalizations, signalling lactation, were studied in 10 Large White x Landrace sows (parity 1-8; housed in the minimal disease piggery at the Veterinary Science Farm, University of Queensland, Australia). Nursing grunts were characterized using Canary 1.2 software to produce a...

  12. Effect of amount and frequency of head-only stunning currents on the electroencephalogram and somatosensory evoked potentials in broilers

    Contributor(s):: Raj, A. B. M., O'Callaghan, M.

    The effectiveness of head-only electrical stunning of broilers, with a root mean square (RMS) current of 100 or 150 mA delivered using either 50, 400 or 1500 Hz sine wave alternating current (AC), was investigated. The changes occurring in the spontaneous electroencephalogram (EEG) were evaluated...
