  1. Behavior of grazing cattle exposed to small populations of stable flies ( Stomoxys calcitrans L.)

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L.

    The authors hypothesized that cattle grazing in the presence of low-level infections of stable flies may offset reductions of grazing time by increasing their rate of herbage intake, and that this may contribute to the determination of economic threshold populations. On 4 consecutive days, 4...

  2. Daily selection of feeding areas by cattle in homogeneous and heterogeneous environments

    Contributor(s):: Bailey, D. W.

    Plots containing 3 heterogeneous patches that varied in forage quality and quantity, and plots containing 3 homogeneous patches were grazed by yearling steers in a 2-part study. During the 1st trial, steers selected patches from a central decision area, and fences divided the patches. During the...

  3. Effects of habitat complexity on the aggressive behaviour of the American lobster ( Homarus americanus ) in captivity

    Contributor(s):: Cenni, F., Parisi, G., Gherardi, F.

    The American lobster, Homarus americanus, is one of the most economically valuable crustacean decapods worldwide, being mostly exploited to foster the live animal industry. Lobsters are typically held in storage facilities where individuals may suffer due to the repeated combats among each other....

  4. Face flies ( Musca autumnalis De Geer) and the behavior of grazing beef cattle

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Bradley, N. W.

    Zero, 400 or 800 laboratory-reared adult face flies (Musca autumnalis De Geer), which had been deprived of nutrients and water for 12 h, were released in large (5 m x 5 m x 2 m) screened enclosures each containing one tethered adult Angus beef cow (Bos taurus) grazing tall fescue (Festuca...

  5. Moderation of grazing behaviour of beef cattle by stable flies ( Stomoxys calcitrans L.)

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L.

    Three concatenated latin squares (4 x 4) were used to evaluate the effects of stable flies on the behaviour of Angus cows grazing in screened enclosures. Four populations (0, 50, 100 and 150) of starved, laboratory-reared stable flies were released into each enclosure at 15 min intervals during 1...

  6. Multiple releases of stable flies ( Stomoxys calcitrans L.) and behaviour of grazing beef cattle

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L., Bradley, N. W.

    A change-over statistical design with complete balance of first residual effects was used with a tethered grazing technique to evaluate the effects of arthropod ectoparasites on the behaviour of adult Angus beef cows (Bos taurus; body weight (BW), 465+or-30 kg) grazing vegetative tall fescue...

  7. Stable flies ( Stomoxys calcitrans L.) and the behaviour of grazing beef cattle

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Burg, J. G., Cornelius, P. L., Bradley, N. W.

    A change-over design with complete balance for first residual effects was used with a tethered grazing technique to evaluate the effects of arthropod ectoparasites on the behaviour of adult Angus beef cows (Bos taurus) (body weight (BW), 465+or-30 kg) grazing vegetative tall fescue (Festuca...

  8. Charismatic krill? Size and conservation in the ocean

    Contributor(s):: Leane, E., Nicol, S.

    The open ocean is an alien place for human beings and for most of history it has been studied using very indirect means. A great deal of what we know about animals that live on land, from ants to elephants, is based on centuries of direct natural history observations of animals alive and in situ....

  9. Does it bite? The role of stimuli characteristics on preschoolers' interactions with robots, insects and a dog

    Contributor(s):: Howard, L., Vick, S. J.

    While there is increasing interest in the impact of animal interactions upon children's wellbeing and attitudes, there has been less attention paid to the specific characteristics of the animals that attract and engage children. We used a within-subjects design to explore how differences in...

  10. Effects of having pets at home on children's attitudes toward popular and unpopular animals

    Contributor(s):: Prokop, P., Tunnicliffe, S. D.

    Having pets at home provides various social, health, and educational benefits to children. The question of how keeping pets at home affects the attitudes of children toward wild animals still has not been answered, due to various methodological issues, such as ignorance of some attitude...

  11. The firefly and the trout: recent shifts regarding the relationship between people and other animals in Japanese culture

    Contributor(s):: Laurent, E. L., Ono, K.

    Scholars of Japan like to point out that the Japanese are interested in tamed (miniature trees, ikebana, gardens) as opposed to wild nature, and that for the Japanese, culture and nature are not mutually exclusive concepts. Moreover, there hardly seems to be any direct relationship between the...

  12. A review of mulesing and other methods to control flystrike (cutaneous myiasis) in sheep

    Contributor(s):: Phillips, C. J. C.

    Flystrike (cutaneous myiasis) in sheep has the potential to have a major impact on the welfare of significant numbers of sheep worldwide, but particularly in Australia. The main control method used in Australia, the mulesing operation to remove folds of skin from the hindquarters of the sheep, is...

  13. Could empathy for animals have been an adaptation in the evolution of Homo sapiens ?

    Contributor(s):: Bradshaw, J. W. S., Paul, E. S.

    In humans, empathy has emotional and cognitive components, both of which are linked to caring and nurturant behaviour. Variations in each of these facets of empathy were likely to have been accessible to natural selection during the evolution of Homo, although the likely details of their...

  14. Protective behaviour of Konik horses in response to insect harassment

    Contributor(s):: Gorecka, A., Jezierski, T.

    The natural protective behaviour displayed by Konik Polski horses against flies was investigated. The factors considered were age (adults versus foals), management system (forest reserve versus pasture), weather conditions and type of horse activity. Twenty-five Konik Polski adults and 18 foals...

  15. Stunning and killing of edible crabs ( Cancer pagurus )

    Contributor(s):: Roth, B., Oines, S.

    The stunning and killing efficiency of ice, superchilling (N2 gas), freezing (-37 degrees C), gradual heating (40 degrees C), boiling, piercing of ganglia, salt baths (NaCl and KCl), gas (CO2) and electricity (50 Hz AC) on edible crabs was studied. Results showed that electricity was the most...

  16. The effect of essential oils showing acaricidal activity against the poultry red mite ( Dermanyssus gallinae ) on aspects of welfare and production of laying hens

    Contributor(s):: George, Sparagano, O. A. E., Port, G., Okello, E., Shiel, R. S., Guy, J. H.

    The poultry red mite (Dermanyssus gallinae) causes severe welfare concerns for laying hens arising from anaemia and disease transmission, and has been identified as an associated risk factor in cannibalistic feather pecking. Previous work suggests that essential oils may offer an alternative to...

  17. The husbandry, welfare and health of captive African civets ( Vivera civetica ) in western Ethiopa

    Contributor(s):: Tolosa, T., Regassa, F.

    A study was carried out during the period from September 2001 to August 2002 in Jimma zone, western Ethiopia to evaluate the husbandry and health of captive African civets (Vivera civetica). Wild civets were found in the wild in all 13 of the districts in the zone, although traditional...
