  1. Behaviour of pigs with viral and bacterial pneumonia

    Contributor(s):: Escobar, J., Alstine, W. G. van, Baker, D. H., Johnson, R. W.

    The behavioural response to infection is well organized and may enhance disease resistance and facilitate recovery, but the behaviour of pigs with an acute respiratory infection has not been assessed. Therefore, the purpose of this study was to evaluate behaviour of pigs inoculated with...

  2. Effect of suckling ('restricted suckling') on dairy cows' udder health and milk let-down and their calves' weight gain, feed intake and behaviour

    Contributor(s):: Froberg, S., Gratte, E., Svennersten-Sjaunja, K., Olsson, I., Berg, C., Orihuela, A., Galina, C. S., Garcia, B., Lidfors, L.

    The aim of this study was to evaluate the effects of restricted suckling (RS) in Holstein cattle on the weight gain, health and behaviour of calves and on udder health and milk let-down in cows compared to artificial rearing (AR). The study was conducted in Mexico. The 27 cows with calves were...

  3. Human handling, flock size and responses to an E. coli challenge in young chickens

    Contributor(s):: Collins, N. W., Siegel, P. B.

    The effects of human handling and flock size on physiological, behavioural and production traits of female chickens were examined in two flocks of 10 and 20 chicks handled gently and spoken to for 1 minute, 3 days a week, and in two similar groups which were not handled. Pullets maintained in...

  4. Pet ownership and knowledge of zoonotic diseases in De Kalb County, Georgia

Respondents were poorly informed about the potential health hazards associated with animals. Only 63% of household heads believed that diseases of pets could be transmitted to humans...

  5. Comparison of indoor and captive, free-roaming management in golden-headed lion tamarins ( Leontopithecus chrysomelas ) at Zurich Zoo

    Contributor(s):: Steinmetz, H. W., Zingg, R., Ossent, P., Eulenberger, U., Clauss, M., Hatt, J. M.

    Traditional husbandry practices for the public display of Callitrichidae involve strict separation of animals and public. An important consideration for the evaluation of such management is the occurrence of health problems and potential zoonotic risks. This study compared animal data and...

  6. The impact of genetic selection for increased milk yield on the welfare of dairy cows

    Contributor(s):: Oltenacu, P. A., Broom, D. M.

    Milk yield per cow has more than doubled in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation. The increase in production should be viewed with concern because: (i) the increase in milk yield has been accompanied by declining fertility, increasing leg and...
