Influence of supplementation method on forage use and grazing behavior by beef cattle grazing bluestem range.
Two 25-d trials (late summer and early winter) were conducted to determine the influence of supplementation method on forage use and grazing behavior. Fifteen ruminally and 12 esophageally fistulated steers (316 and 400 kg, respectively) were blocked by weight and assigned randomly to one of three treatments: 1) self-feeding supplement (via Calan gates) with salt as a limiting agent; 2) daily h...
متن کاملForages and Pastures: Grazing and Forage Management
The objective of this study was to compare summer annuals for fall and winter grazing on irrigated pastures in the Intermountain West. The cool desert areas of this region have short growing seasons (≤120 d) with high daytime temperatures and cool nights resulting in sufficent growing degree days, but impaired production on cool season forages during late summer. Five species were planted in Ca...
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...
متن کاملPredicting Forage Intake by Grazing Beef Cows
The control of feed intake by ruminants is complex, and developing a cohesive theory of intake control in ruminants continues to be a challenge. Because our understanding of factors that regulate intake by cattle is inadequate, predicting feed intake, even under the best of circumstances, is difficult. In grazing cattle, this difficulty is exacerbated by additional influences that can sway basi...
متن کاملSupplementary Feeding of Grazing Beef Cattle
Some 60% of Australia% beef cattle are located in the tropics and subtropics, grazing, in general native pastures of low digestibility and N content. Production per head is low, as also are reproductive rates. The nutritional problem centres around the low contents of phosphorus, sulphur and nitrogen in pastures from June to December. This paper discusses responses in breeding cattle to supplem...
