Effects Of Prescribed Fire Timing On Native Plant Composition, Forage Biomass Accumulation, And Root Carbohydrate Reserves In The Kansas Flint Hills: Year 2 Of 6, Z. M. Duncan, A. J. Tajchman, M. P. Ramirez, J. Lemmon, W. R. Hollenbeck, D. A. Blasi, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Objective:The objective was to document the effects of prescribed fire timing on native plant composition, forage biomass, and root carbohydrate concentrations in key native tallgrass species in the Kansas Flint Hills.

Study Description:This experiment was conducted at the Kansas State University Beef Stocker Unit. Eighteen pastures were grouped by watershed and assigned to one of three prescribed-burn treatments: spring (April 7 ± 2.1 days), summer (August 21 ± 5.7 days), or fall (October 2 ± 9.9 days). Botanical composition, forage biomass, and root carbohydrate concentrations in big bluestem, little bluestem, Indian grass, and purple prairie clover were evaluated …

Yearling Cattle Grazing Pastures Burned During Summer Perform Similarly To Cattle Grazing Pastures Burned In Early Spring: Year 2 Of 6, Z. M. Duncan, A. J. Tajchman, M. P. Ramirez, J. Lemmon, W. R. Hollenbeck, D. A. Blasi, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Objective:The objective was to evaluate the impact of prescribed fire timing on grazing performance of yearling beef cattle in the Kansas Flint Hills.

Study Description:This study was conducted at the Kansas State University Beef Stocker Unit. Yearling stocker cattle were assigned randomly to one of three prescribed-burn treatments: spring (April 7 ± 2.1 days), summer (August 21 ± 5.7 days), or fall (October 2 ± 9.9 days) and grazed from May to August of 2019 and 2020. Individual body weights were recorded at the beginning and end of the grazing season to determine total body weight gain and …

Evaluation Of Implants, Clover, And Fescue Variety On Stocker Steers, Z. T. Buessing, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Sixty-four growing steers were used in a split-plot experiment, where the whole plot was pasture, and the split-plot was implants. Whole plot treatment was a 4 × 2 facto­rial with four levels of fescue (High Endophyte, Low Endophyte, Novel, or Endophyte Free) and two levels of legume (Legumes or No Legumes). The split-plot included four implant levels (No Implant, Synovex One Grass, Revalor-G, Ralgro). Data collected were weights, hair coat scores, hair length, rectal temperature (every 28 days), and ultrasound carcass characteristics coming off grass. Steers on High Endophyte had the lowest average daily gain (ADG), longest hair, and highest …
