The effect of some common management practices on the ease of handling of dairy cows
Autor: J. F. Hurnik, N.J. Lewis
Publikováno v: Applied Animal Behaviour Science. 58:213-220
Cows which are fearful of humans can be difficult and, in some cases, dangerous to handle (Hemsworth et al., 1989; Boivin et al., 1992; De Passille et al., 1996). Since fear is evoked by painful or otherwise aversive situations, and since many proced

Effect of music on voluntary approach of dairy cows to an automatic milking system
Autor: Katsuji Uetake, L. Johnson, J. F. Hurnik
Publikováno v: Applied Animal Behaviour Science. 53:175-182
The main objective of this experiment was to assess the effect of music on the voluntary approach of cows to an automatic milking system (AMS). A group of 19 mid- and late-lactating Holstein cows with 2 months prior experience of twice-daily milking

The Long-Term Productivity of Hens Housed in Battery Cages and an Aviary
Autor: Allison A. Taylor, J. F. Hurnik
Publikováno v: Poultry Science. 75:47-51
This study examined the long-term effects of housing system on several aspects of laying hen production. At 19 wks of age, 336 White Leghorn hens were placed, 3 birds per cage, into battery cages; 437 birds were assigned to an aviary with communal ne

The application of cost-benefit dominance analysis to the assessment of farm animal quality of life
Autor: J. F. Hurnik, H. Lehman, A. A. Taylor
Publikováno v: Social Indicators Research. 35:313-329
A holistic approach to the subject of animal well-being suggests that it cannot be attributed to (or measured by) a single biological factor, but rather results from a summation of all influences upon an individual's quality of life with a satisfacto

The behavior of gestating swine housed in the Hurnik-Morris system
Autor: M M Buhr, J. F. Hurnik, J R Morris, R M Friendship, O. B. Allen
Publikováno v: Journal of Animal Science. 71:3280-3284
A group housing system for sows, the Hurnik-Morris (HM) system, was developed to address several of the perceived animal welfare limitations of existing housing methods. The HM system permits socially coordinated eating and resting, controlled and so

The performance of gilts in a new group housing system: endocrinological and immunological functions1
Autor: J R Morris, J. F. Hurnik, M M Buhr, Bonnie A. Mallard, E. von Borell
Publikováno v: Journal of Animal Science. 70:2714-2721
The effect of a new group housing system on performance (132 gilts and litters) and endocrinological (35 gilts) and immunological functions (28 gilts) was studied. Animals were randomly assigned to a conventional system (control), involving greater t

Comparison of Behavior and Performance of Laying Hens Housed in Battery Cages and an Aviary
Autor: J. F. Hurnik, Toshio Tanaka
Publikováno v: Poultry Science. 71:235-243
Experiments were carried out to study the behavior and production performance of hens housed in battery cages (3 birds x 112 cages) and an aviary (437 birds). Direct visual observations and videotapings of hen behavior were collected at 24 to 25, 36

Use of body surface area to set minimum space allowances for confined pigs and cattle
Autor: J. F. Hurnik, N. J. Lewis
Publikováno v: Canadian Journal of Animal Science. 71:577-580
The necessity to set minimum space allowances for confined animals has become more urgent as economic pressures have forced the use of increasingly intensive housing. This paper proposes that 50% of body surface area be adopted as a minimum space all

Behavioral Responses of Hens to Simulated Dawn and Dusk Periods
Autor: Toshio Tanaka, J. F. Hurnik
Publikováno v: Poultry Science. 70:483-488
Behavioral responses to caged (3 birds by 6 cages) and aviary (437 birds) hens to sudden (S) and gradual (G) changes in illumination were recorded using an infrared camera. They were observed from 2 days before the change from S to G, to 7 days after
