Particle Size Changes in Rumens of Cattle Grazing Kansas Flint Hills Range
A ruminally fistulated Hereford steer and heifer grazing Kansas Flint Hills range were used with the objective of determining forage particle breakdown and distribution in different rumen sites over several hours post feeding during seasons of differing forage quality. During the first year, samples were taken after an overnight fast from 3 rumen sites and from feces early on the sample morning...
متن کاملNutrient Removal Rates from Ruminoretic- ula of Cattle Grazing Kansas Flint Hills
A Hereford steer and heifer were used to compare rumen removal rates of forage nutrients from Kansas Flint Hills range over a 2-year period. Rumens were emptied after an overnight fast and the contents sampled, weighed, and returned to the mmen. The cattle were then fed a known amount of range forage and fasted for 12 hours, at which time the rumen evacuation procedure was repeated. Removal rat...
متن کاملEffects of Range Burning on Kansas Flint Hills Soil
Highlight: Two tallgrass prairie areas burned annually for 20 (grazed) nnd 48 (un. grazed) years ar different fimeS showed differences in soil chemical and physical properties. Winter, early-spring, and mid-spring burned ungrared plots were generally higher in soil pH, organic ma~fer, and K than late-spring burned or unburned plots. Late-Jpring and winter burning lowered soil N on ungrazed and ...
متن کاملEvaluation of Eastern Redcedar Infestations in theNorthern Kansas Flint Hills
Highlight: Associations among cattle stocking rate, precipitation, and eastern redcedar invasion, and possibly redcedar control measures were investigated. Redcedar numbers generally decreased as stocking rate increased. Precipitation had only a slight effect on invasion rate. Fire, cutting, and fenuron granules appear to effectively kill red cedar. Loamy upland range site consists of soils hav...
متن کاملEffects of mineral-supplement delivery system on frequency, duration, and timing of supplement use by beef cows grazing topographically rugged, native rangeland in the Kansas Flint Hills.
The effects of mineral-supplement delivery system on patterns of supplement use by grazing beef cows were measured in 2 studies. Study 1 was conducted on 4 pastures grazed by pregnant, mature beef cows (BW = 562 ± 38 kg) from February to May. Study 2 was conducted on 4 pastures grazed by lactating beef cows (BW = 579 ± 54 kg) and their calves from May to September. Treatments were mineral deliv...
