  1. Patterns and frequency of social interactions in young grazing bulls and steers

    Contributor(s):: Hinch, G. N., Lynch, J. J., Thwaites, C. J.

    Two herds of Hereford cattle, each containing bulls and steers, were observed at ages between 10 and 18 months. Bulls showed higher frequencies of all interactions except grooming and running, but the differences between bulls and steers were significant only at ages greater than 14 months. A...

  2. Relationship between dispersion behaviour of free-ranging cattle and forage conditions

    Contributor(s):: Dudzinski, M. L., Muller, W. J., Low, W. A., Schuh, H. J.

    Distribution of cattle grazing the rangeland communities of a 170-km2 paddock in central Australia was determined by aerial survey at fortnightly intervals over 4.5 years. Cattle groups were generally more clumped than would be expected at random. Cattle aggregated into larger groups, and the...

  3. Social behaviour in domestic livestock: the basis for improved animal husbandry

    Contributor(s):: Squires, V. R.

    Factors affecting social behaviour of cattle, sheep and goats are discussed including factors of the plant community, grazing behaviour, environment and management.

  4. Social organization and leadership in a grazing herd of suckler cows

    Contributor(s):: Benham, P. F. J.

  5. Spatial analysis of grazing animals: a critique of some methods

    Contributor(s):: Eddison, J. C., Wood-Gush, D. G. M., Muetzelfeldt, R. I.

  6. Spatial relationships within a herd of young sterile bulls and steers

    Contributor(s):: Hinch, G. N., Thwaites, C. J., Lynch, J. J., Pearson, A. J.

  7. Statistical and probabilistic estimators of forage conditions from grazing behaviour of Merino sheep in a semi-arid environment

    Contributor(s):: Dudzinski, M. L., Schuh, H. J., Wilcox, D. G., Gardiner, H. G., Morrissey, J. G.

    The flock structure of Merino ewes and rams was recorded from the air in 22 surveys over 3 yr in a large semi-arid area of W. Australia. Forage production and body wt. data were collected over the same period. A dispersion index, DI (with zero value when all the sheep were in 1 group and with...

  8. Studies on the formation of ungrazed eliminative areas in fields used by horses

    Contributor(s):: Odberg, F. O., Francis-Smith, K.

    Horses accepted cut grass from areas left ungrazed and used for elimination as long as faeces were not present. This indicated that aversion to faeces rather than a difference in palatability led to ungrazed areas in pastures.

  9. The effects of fasting prior to sampling and diurnal variations on certain aspects of grazing behaviour in cattle

    Contributor(s):: Chacon, E., Stobbs, T. H.

    In cattle grazing tropical grass pastures, bite size varied with the pasture species and stage of defoliation, but only varied slightly following overnight fasting. Data were given on DM yield, sward structure and nutritive value of Setaria anceps cv. Kazungula, Panicum maximum var. trichoglume,...

  10. The effects of maternal influences on sheep: breed differences in grazing, resting and courtship behaviour

    Contributor(s):: Key, C., Maciver, R. M.

    Clun Forest and Welsh Mountain sheep were lambed over the same period in a lowland area and half the lambs were cross-fostered by the other breed. 2 wk after lambing was over, half the female lambs with their dams were transferred to fenced upland pastures, the breeds being kept separate, until...

  11. The influence of shape of paddock, type of fence and stocking rate on grazing behaviour and social facilitation in Merino sheep

    Contributor(s):: Lynch, J. J., Hedges, D. A.

    Grazing behaviour trials were carried out between Oct. 1964 and Sept. 1965 with Merino ewes, 18 months old, in paddocks on a predominantly Phalaris aquatica/white clover pasture with some perennial ryegrass, tall fescue and subterranean clover. It was concluded that grazing patterns adopted by...

  12. A method for assessing the relative sociability of individuals within groups: an example with grazing sheep

    Contributor(s):: Sibbald, A. M., Elston, D. A., Smith, D. J. F., Erhard, H. W.

    We describe a method for quantifying relative sociability within a group of animals, which is defined as the tendency to be close to others within the group and based on the identification of nearest neighbours. The method is suitable for groups of animals in which all individuals are visible and...

  13. A note on diet selection by goats on a semi-arid temperate rangeland throughout the year

    Contributor(s):: Ricardi, C., Shimada, A.

    A descriptive study and an experiment assessed the selectivity of goats on restricted grazing on a semi-arid temperate rangeland. In 1987 a mixed-breed herd was monitored once a week for 16 consecutive weeks from April to July. In April, July and October of 1989, and January of 1990, the same...

  14. A note on eating behaviour of dairy cows at different stocking systems - diurnal rhythm and effects of ambient temperature

    Contributor(s):: Taweel, H. Z., Tas, B. M., Smit, H. J., Tamminga, S., Elgersma, A.

    This experiment was aimed at studying the diurnal rhythm of dairy cows eating behaviour at different stocking systems, and quantifying the effect of daily ambient temperature on this diurnal rhythm. In two experiments carried out in the summer of 2003 in The Netherlands, eight dairy cows were...

  15. A test for measuring individual variation in how far grazing animals will move away from a social group to feed

    Contributor(s):: Sibbald, A. M., Erhard, H. W., Hooper, R. J., Dumont, B., Boissy, A.

    This paper describes a test for gregarious grazing animals, which measures trade-offs between feeding and social companionship. Four groups of 10 female Scottish Blackface sheep were used for the study and bowls containing food pellets were used to draw individuals away from the group. The sheep...

  16. Bactrian camel foraging behaviour in a Haloxylon ammodendron (C.A. Mey) desert of Inner Mongolia

    Contributor(s):: Zhao, MengLi, Willms, W. D., Han, GuoDong, Jin, Ye

    The Bactrian camel (Camelus bactrianus ferus) is uniquely adapted to the deserts of China and Mongolia. It was domesticated about 3000 years ago but the wild Bactrian camel is endangered with less than 1000 remaining in China. We observed the foraging behaviour of 10 domestic Bactrian camels...

  17. Bite dimensions and grazing movements by sheep and cattle grazing homogeneous perennial ryegrass swards

    Contributor(s):: Rook, A. J., Harvey, A., Parsons, A. J., Orr, R. J., Rutter, S. M.

    Pairs of ewes or heifers were allowed to graze for short periods from previously prepared 'homogeneous' areas of ryegrass, in order to study their bite dimensions and movement patterns and to investigate the role of different species in initiating spatial heterogeneity. Apparent bite area was...

  18. Bite mechanics of cattle and sheep grazing grass-dominant swards

    Contributor(s):: Woodward, S. J. R.

    Numerous experiments have shown that animals grazing pasture remove only a portion of the sward height offered and that bite area increases with sward height but decreases slightly as sward bulk density increases. A number of theories have been proposed to explain these patterns. One suggestion...

  19. Cattle generalise visual cues from the pen to the field to select initial feeding patches

    | Contributor(s):: Renken, W. J., Howery, L. D., Ruyle, G. B., Enns, R. M.

    Free-grazing ruminants forage in environments containing multiple levels of complexity; the forage selection process operates at the landscape scale, when selecting feeding sites, and at the plant part level when selecting actual bites. Pen trials have shown that livestock associate visual cues...

  20. Classifying cattle jaw movements: comparing IGER Behaviour Recorder and acoustic techniques

    | Contributor(s):: Ungar, E. D., Rutter, S. M.

    The identification and classification of jaw movements is essential to a mechanistic understanding of the intake process. Two methods for the detection and classification of jaw movements in grazing dairy cattle were compared: the IGER Behaviour Recorder (IBR) and acoustic monitoring (ACM)....
