Two ruminally cannulated steers were used in an in situ incubation study to test the effects of raw cull Great Northern beans ( Phaseolus vulgaris ), canola meal, and sunflower meal on rate and extent of digestion of forage DM, NDF, ADF, and N and to

Comparative foraging strategies of sheep and goats in a T-maze apparatus

Autor: R.W. Richards, David M. Swift, E. Hosoi, L.R. Rittenhouse

Publikováno v: Applied Animal Behaviour Science. 44:37-45

The foraging behavior of eight sheep and 11 goats was studied using a T-maze. In the first experiment, animals were given two free choices in the maze. In each case, the selection of either arm would result in their obtaining high quality food—a si

Foraging strategies of cattle in a Y-maze: influence of food availability

Autor: E. Hosoi, L.R. Rittenhouse, David M. Swift, R.W. Richards

Publikováno v: Applied Animal Behaviour Science. 43:189-196

Three studies were conducted to investigate how cattle determine where to begin a foraging bout. Studies were designed to measure (1) the inherent tendency of cattle to shift after a successful foraging bout, and (2) the way cattle cognitively change

Effect of trailing to water on temporal behavior and ingestion of herded sheep in Morocco

Autor: L.R. Rittenhouse, A. El Aich, M. El Asraoui

Publikováno v: Applied Animal Behaviour Science. 31:251-257

A case study was conducted in the Ait M'hamed (Middle Atlas, Morocco) to document the effect of trailing to water on the temporal behavior and ingestion by herded sheep. When the sheep were watered every other day, it was found that on the watering d

Sequential analysis of cattle location: Day-to-day movement patterns

Autor: Derek W. Bailey, John W. Walker, L.R. Rittenhouse

Publikováno v: Applied Animal Behaviour Science. 25:137-148

Studies were conducted in Texas and Colorado to determine if there were consistent movement patterns of grazing cattle. Based on optimal foraging theory, we hypothesized that cattle would select the same area of a pasture to graze for several days in

Research observation: Daily movement patterns of hill climbing and bottom dwelling cowsfull access

Autor: Derek W. Bailey, L.R. Rittenhouse, Martina R. Keil

Publikováno v: Journal of Range Management. 57

Individual animal selection has been proposed as a tool for increasing uniformity of grazing on rugged rangeland. Daily grazing patterns of cows previously identified as preferring steeper slopes and higher elevations (hill climbers) were compared to

Grazing and Plant Performance

Autor: M. J. Trlica, L.R. Rittenhouse

Publikováno v: Ecological Applications. 3:21-23

Grazing is more than just defoliation of plants. The impact of herbivory affects ecosystem structure and function, both above and below ground. Ultimately, effects of herbivory are expressed to varying degrees at many levels of the ecosystem. Herbivo

Performance of beef cows receiving cull beans, sunflower meal, and canola meal as protein supplements while grazing native winter range in Eastern Colorado

Autor: J.C. Whittier, D N Schutz, L.R. Rittenhouse, H.H. Patterson

Publikováno v: Journal of animal science. 77(3)

A 2-yr grazing performance study was conducted in Eastern Colorado to evaluate the effects of feeding raw cull beans (Phaseolus vulgaris) or canola meal, compared to sunflower meal, to beef cows grazing dormant, native winter range on body weight and
