Grazing behavior and energy expenditure by sheep and goats co-grazing grass/forb pastures at three stocking rates
A study was conducted to assess effects of stocking rate (SR) on grazing behavior and energy expenditure (EE) by growing sheep and goat wethers co-grazing grass/forb pastures. Grazing was for 16-week periods in 2002 and 2003. Pastures consisted of various grasses, primarily bermudagrass (Cynodon dactylon) and johnsongrass (Sorghum halepense), and forbs (e.g., ragweed; Ambrosia spp.). Sheep (Kha...
متن کاملLivestock and Vegetation Responses to Stocking Rate and Grazing System
INTRODUCTION Vegetation and livestock responses from a 25 year (1982-2006) grazing system and stocking rate study in the northern mixed-grass prairie at the USDA-Agricultural Research Service, High Plains Grasslands Research Station near Cheyenne, Wyoming are presented here. This study was longest known grazing system X stocking rate study in North America and was one of the few studies to use ...
متن کاملMilk production of fall-calving dairy cows during summer grazing of grass or grass-clover pasture.
Milk production of fall-calving dairy cows during subsequent summer grazing was evaluated in two consecutive years using a total of 80 mid- to late-lactation Holsteins. Cows calved during September and October and grazed from April to August in the following year. In yr 1, 27 cows grazed a native grass pasture and 13 cows grazed a native grass-clover mixed pasture containing 26% red clover and ...
متن کاملGrazing methods and stocking rates for direct-seeded alfalfa pastures: I. Plant productivity and animal performance.
A 4-yr study was conducted to determine the effects of two grazing methods (GM) at two stocking rates (SR) on alfalfa pasture plant productivity and animal performance and to ascertain the effect of grazing systems on subsequent performance of steers fed a high-concentrate diet. Eight pasture plots (.76 ha) were seeded in 1988 with alfalfa (Medicago sativa L. var. WL225) and divided into two bl...
متن کاملForages and Pastures: Grazing and Forage Management
Pastures located on southern Iowa cow/calf farms, from 8 to 125 ha in size, were used to evaluate the effects of microclimate, shade, botanical composition, and other pasture characteristics influencing the temporal/ spatial distribution of cattle within and outside streamside zones of pastures. Cows were Angus and Angus-cross on 4 of the farms, and Mexican Corriente on the remaining farm. Duri...
