Case Study: Effect of cattle and sheep grazing on stocking rate and botanical composition of subirrigated pasture
Changes in commodity pricing and environmental concerns are changing animal agriculture throughout the United States. Adopting multispecies grazing as an alternative production system could result in improved forage utilization, increased animal performance, and reduced production costs, and thereby improve the financial stability of livestock operations. This study focused on the Silver Spur R...
متن کاملThe Estimation of Pasture Intake by the Grazing Sheep
The few estimates in the literature of the quantity of food eaten by the grazing sheep have involved calculations based on some component of the faeces. ’ The “apparent digestibility” of this component was first calculated with sheep fed on known amounts of cut pasture. Faeces were then collected from grazing sheep and the amount of the particular component in the faeces was used to predict the...
متن کاملSoil Changes Associated with Cessation of Sheep Grazing in the Canterbury High Country, New Zealand
Soil degradation has been implicated as a cause of the poor vegetation condition over much of the unimproved tussock grassland in the South Island high country and as a threat to the sustainability of extensive pastoralism (Parliamentary Commissioner for the Environment, 1991; South Island High Country Review Working Party, 1994). A key requirement for assessment of sustainability is an ability...
متن کاملFORAGES AND PASTURE MANAGEMENT Herbage Productivity and Botanical Composition of Hill Pasture as a Function of Clipping and Site Features
factors influencing the distribution of prairie species in complex terrain in central Canada (Lieffers and LarkinComplex topography and varied soil of hill-land pastures create Lieffers, 1987). Slope aspect also influenced diversity microsite conditions that support an array of floristic associations and herbage production patterns. This complicates management for forage of naturalized flora oc...
متن کاملStable carbon isotope composition of perirenal adipose tissue fatty acids from Engadine sheep grazing either mountain or lowland pasture.
To provide further insights into ruminant lipid digestion and metabolism, and into cis-9,trans-11 18:2 synthesis, 12 growing Engadine lambs grazing either mountain pasture (2,250 m above sea level; n = 6) or lowland pasture (400 m above sea level; n = 6) were studied. Both pastures consisted exclusively of C(3) plants. Before the experiment, all animals grazed a common pasture for 6 wk. Grasses...
