One-hundred-and-forty-four steers were given one of three human handling and yarding...

  6. Relationships between bunk attendance, intake and performance of steers and heifers on varying feeding regimes

    Contributor(s):: Schwartzkopf-Genswein, K. S., Atwood, S., McAllister, T. A.

    Six crossbred heifers (average weight 481+or-22 kg) and six crossbred steers (average weight 471+or-44 kg) were penned individually in pens 2 m x 5 m in size. Feeding behaviours during ad libitum (Day 0-28) and restricted intake (95% of ad libitum; Day 29-54) were derived from bunk attendance...

  7. The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle

    Contributor(s):: Olmos, G., Turner, S. P.

    A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...

  8. Effects of social learning on foraging behaviour and live weight gain in first-season grazing calves

    Contributor(s):: Hessle, A. K.

    When livestock are turned out to semi-natural grasslands, an effective onset of grazing is important both for animal productivity and for defoliation of the sward, which preserve the biodiversity of the vegetation. The aim of this study was to investigate whether foraging behaviour of naive...

  9. Floor quality and space allowance in intensive beef production: a review

    Contributor(s):: Wechsler, B.

    In intensive beef production in Europe, finishing beef cattle are typically reared in pens with fully slatted floors and low space allowances. These housing conditions were questioned in a report published by the Scientific Committee on Animal Health and Animal Welfare in 2001. The report...

  10. Effect of repeated regrouping and relocation on behaviour of steers

    | Contributor(s):: Sandeep, Gupta, Earley, B., Nolan, M., Formentin, E., Crowe, M. A.

    To investigate the effect of repeated regrouping and relocation (R&R) on behaviour of steers, 72 Holstein-Friesian (14-month-old; 441+or-3.2 kg) steers were assigned to either control (n=30; C) or regrouped (n=42; R) treatments and housed six per pen in 12 pens. The R steers were exposed to...

  11. Effects of pre-haul management and transport duration on beef calf performance and welfare

    | Contributor(s):: Schwartzkopf-Genswein, K. S., Booth-McLean, M. E., Shah, M. A., Entz, T., Bach, S. J., Mears, G. J., Schaefer, A. L., Cook, N., Church, J., McAllister, T. A.

    Behavioural and physiological indicators of stress as well as growth performance, and morbidity rates were assessed in 174 steer calves (220+or-37 kg) for 30 days after transport from ranch-to-feedlot. The calves were conditioned (C) or not (NC), and subjected to short- (2.7 h, S) or long-hauling...

  12. Behavioural response to mixing of entire bulls, vasectomised bulls and steers

    | Contributor(s):: Mohan Raj, A. B., Moss, B. W., McCaughey, W. J., McLauchlan, W., Kilpatrick, D. J., McGaughey, S. J.

    Four groups of cattle each consisting of 2 entire bulls, 2 vasectomized bulls and 2 steers, were created by mixing the constituent animals together and their homosexual (teasing and mounting) and aggressive (butting and pushing) behaviours were investigated in detail for the initial 4-h period....

  13. Changes in temporal and spatial associations between pairs of cattle during the process of familiarisation

    | Contributor(s):: Patison, K. P., Swain, D. L., Bishop-Hurley, G. J., Robins, G., Pattison, P., Reid, D. J.

    Mixing unfamiliar individuals is a common practice in livestock production systems. However, a change in social structure can create social stresses, which can adversely affect animal welfare and reduce production. In this study, social interaction metrics were used to investigate interaction and...

  14. Social companionship versus food: the effect of the presence of familiar and unfamiliar conspecifics on the distance steers travel

    | Contributor(s):: Patison, K. P., Swain, D. L., Bishop-Hurley, G. J., Pattison, P., Robins, G.

    The social motivation of a grazing individual to remain in close proximity to its peer is dependent on many factors, particularly the level of familiarity with its peers and the desire to forage further away. This study examined the trade-off individual cattle have to make between a food reward...

  15. Diet selection by cattle offered a choice between swards treated or untreated with slurry: effects of application method and time since application

    | Contributor(s):: Laws, J. A., Rook, A. J., Pain, B. F.

    Grass turves 0.25 msuperscript 2 were placed on a 20-cm deep soil base in a sward box. Dairy cow slurry, applied at a rate of 36 msuperscript 3/ha, was spread evenly on the surface (S), or poured into 2 slots cut into the sward 10 cm apart and 5 cm deep, to simulate shallow injection (I). Control...

  16. Individual differences in the reaction of beef cattle to situations involving social isolation, close proximity of humans, restraint and novelty

    | Contributor(s):: Kilgour, R. J., Melville, G. J., Greenwood, P. L.

    Forty-eight steers and 46 heifers were each subjected to a series of 11 behavioural tests on 3 occasions, separated by intervals of 3 and 4 weeks. The tests performed were restraint in a crush, flight time, fear of humans, flight distance, ease of sorting, following, lateralisation, open field,...

    | Contributor(s):: Corkum, M. J., Bate, L. A., Tennessen, T., Lirette, A.

    Hereford steers, average weight 230+or-23 kg, in a 28-day trial period, had access to an individual electronically controlled Calan Broadbent feeder or to 3 or 4 feeders (groups A, B and C, respectively). The steers were fed grass legume silage ad libitum with fresh silage added 4 times daily. 24...

  19. Diet and habitat selection by cattle: the relationship between skin- and gut-defense systems

    | Contributor(s):: Cibils, A. F., Howery, L. D., Ruyle, G. B.

    Animals possess an external or skin-defense system that protects them from aggressions inflicted by predators, and an internal or gut-defense system that deters them from over-ingesting toxins. We conducted a study with cattle to investigate the relation between skin- and gut-defense systems and...

  20. Foraging mechanics and their outcomes for cattle grazing reproductive tropical swards

    | Contributor(s):: Benvenutti, M. A., Gordon, I. J., Poppi, D. P., Crowther, R., Spinks, W.

    For grazing animals an important determinant of animal performance is the rate of nutrient intake (RNI) which depends on diet quality and instantaneous intake rate (IIR). In turn, diet quality and IIR are the outcome of the interaction between the morphology and behaviour of the animal and the...
