  1. Daytime summer access to pasture vs. free-stall barn in dairy cows with year-long outdoor experience: A case study

    Contributor(s):: Shepley, Elise, Bergeron, Reneé, Vasseur, Elsa

    With its documented health and behavioural benefits, one would expect dairy cows to have near unconditional preference for pasture. However, dairy cow preference is multifaceted with numerous factors contributing to the choices and or actions of the cow. Experience is one such factor that may...

  2. Defaecation and urination behaviour in beef cattle grazing semi-natural grassland

    Contributor(s):: Orr, Robert J., Griffith, Bruce A., Champion, Robert A., Cook, James E.

    There is increasing global interest in the extent to which multi-species grasslands containing increased plant diversity compared with improved grasslands can also deliver higher resource protection. The objective of this experiment was to examine nutrient returns via faeces and urine by...

  3. Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes

    Contributor(s):: Cornelissen, P., Vulink, J. T.

    For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...

    Contributor(s):: Mheen, H. W. van der, Spoolder, H. A. M.

  5. Development of a methodology for studying feeding station behaviour of grazing ewes

    Contributor(s):: Roguet, C., Prache, S., Petit, M.

    A test apparatus was developed to study feeding station (FS) use and abandonment by sheep, by controlling FS number, characteristics and distance between FS. It consisted of a rectangular pen with openings in one of the long sides through which the sheep could extend its head to graze. FS...

  6. Diet choice in grazing sheep: a new approach to investigate the relationships between preferences and intake-rate on a daily time scale

    Contributor(s):: Prache, S., Bechet, G., Damasceno, J. C.

    For the herbivore grazing heterogeneous vegetation, optimal foraging theory has been proposed to predict which food components would be included in the diet on the basis of their relative profitability. We investigated the relationships between preferences and intake-rate in four groups of six...

  7. 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...

  8. Diet selection in dairy goats grazing woody Mediterranean rangeland

    Contributor(s):: Perevolotsky, A., Landau, S., Kababia, D., Ungar, E. D.

    Species selection, diet quality and voluntary intake were studied in Anglo-Nubian x Damascus dairy goats grazing woody Mediterranean rangeland in the Jerusalem Hills, Israel. Measurements comprised direct observation of grazing behaviour, with the recording of all species encountered along the...

  9. Diet selection of bonded and non-bonded free-ranging sheep and cattle

    Contributor(s):: Anderson, D. M., Hulet, C. V., Hamadeh, S. K., Smith, J. N., Murray, L. W.

    Previously published data have demonstrated that when young lambs are bonded to cattle, they will follow cattle under free-ranging conditions. This close association under free-ranging conditions has been shown to reduce coyote (Canis latrans) predation on lambs. However, in addition to...

  10. Dietary preference of dairy heifers grazing ryegrass and white clover, with and without an anti-bloat treatment

    Contributor(s):: Rutter, S. M., Orr, R. J., Yarrow, N. H., Champion, R. A.

    The effect of an antibloat treatment on the dietary preference of nonpregnant Holstein x Friesian heifers for ryegrass and white clover was studied. Eight groups of two heifers grazed 0.51 ha plots containing adjacent monocultures of grass alongside clover with either 25 or 75% clover (by ground...

  11. Differences among beef sire breeds and relationships between terrain use and performance when daughters graze foothill rangelands as cows

    Contributor(s):: VanWagoner, H. C., Bailey, D. W., Kress, D. D., Anderson, D. C., Davis, K. C.

    A study was conducted on foothill rangeland to determine if breed of sire affected grazing distribution patterns and to evaluate relationships between individual grazing patterns and performance of beef cows. Angus (AN), Charolais (CH), Piedmontese (PI), and Salers (SA) sires were mated to dams...

  12. Differences in behaviour of free-ranging cattle in the tropical climate

    Contributor(s):: Langbein, J., Nichelmann, M.

    The grazing behaviour of Holstein Friesian and Siboney de Cuba (5/8 Holstein Friesian X 3/8 Cuban Zebu) lactating cows was studied during the dry season and the rainy season in the tropical climate of Cuba. Grazing, total activity, standing and lying, time spent in the sun and time spent in the...

  13. Differences in ewe and wether behavior when bonded to cattle

    Contributor(s):: Anderson, D. M., Estell, R. E., Havstad, K. M., Shupe, W. L., Libeau, R., Murray, L. W.

    The intra- and inter-species associations of cattle and sheep grazing the same pasture were investigated. Under mixed stocking, sheep did not associate with cattle; however, sheep consistently stayed close to (bond) and followed cattle if they were forced in close association with cattle at an...

  14. Differences in home range and habitat use among individuals in a cattle herd

    Contributor(s):: Howery, L. D., Provenza, F. D., Banner, R. E., Scott, C. B.

    A field study was conducted on the Maxfield-Thompson Grazing Allotment in the Sawtooth National Forest, Idaho, to investigate the differences in home range (HR) and habitat use (HU) of individual cows (that use certain areas (e.g. riparian grasslands) more than others (e.g. upland grasslands))...

    The effects of time of day on the ingestive behaviour of groups of 5 sheep grazing monocultures of ryegrass (Lolium perenne cv. Parcour) or white clover (Trifolium repens cv. Kent Wild White), were measured over periods of 1 h starting at 07.30, 11.30, 15.30 and 19.30 h in August 1993. Grazing...

  18. Do sheep use umami and bitter tastes as cues of post-ingestive consequences when selecting their diet?

    Contributor(s):: Favreau, A., Baumont, R., Ferreira, G., Dumont, B., Ginane, C.

    Grazing herbivores use their senses to select their diet. As tastes could reveal certain plant properties, we investigated whether sheep use them as cues to anticipate post-ingestive consequences. We focused on umami and bitter tastes reported to be associated with protein and toxin contents,...
