Use Of Uav Imagery And Nutrient Analyses For Estimation Of The Spatial And Temporal Contributions Of Cattle Dung To Nutrient Cycling In Grazed Ecosystems, Amanda Shine
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Nutrient inputs from cattle dung are crucial drivers of nutrient cycling processes in grazed ecosystems. These inputs are important both spatially and temporally and are affected by variables such as grazing strategy, water location, and the nutritional profile of forage being grazed. Past research has attempted to map dung deposition patterns in order to more accurately estimate nutrient input, but the large spatial extent of a typical pasture and the tedious nature of identifying and mapping individual dung pats has prohibited the development of a time- and cost-effective methodology. The first objective of this research was to develop and validate …
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2017, Leah English, Jennie Popp, Wayne Miller
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2017, Leah English, Jennie Popp, Wayne Miller
Research Reports and Research Bulletins
Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, and also leads to economic activity in other parts of the economy. This report is the eleventh in a series of reports examining agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value …
Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer
Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
A total of 360 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, and 2018. Daily gains of steers that grazed MaxQ fescue, wheat-bermudagrass, or wheat-crabgrass were similar (P>0.05) in 2010, 2016, 2017, and 2018. Daily gains of steers that grazed wheat-bermudagrass or wheat-crabgrass were greater (P>0.05) than those that grazed MaxQ fescue in 2011 and 2012. Daily gains of steers that grazed wheat-crabgrass were greater (P>0.05) than those …
Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer
Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
A total of 180 steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014, 2015, 2016, 2017, and 2018. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the primary source of energy. Supplements were formulated to provide the same quantity of protein and energy per head daily. Supplementation with the starch-based or fat-based supplement during the grazing phase resulted in higher (P<0.05) grazing gains than feeding no supplement during all five years. In 2014, 2016, 2017, and 2018, grazing gains of steers supplemented with the starch-based or fat-based supplement were similar (P>0.05). In 2015, steers supplemented with …

Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing And Subsequent Finishing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer
Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing And Subsequent Finishing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
One hundred ninety-two yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and interseeding ladino clover on available forage, grazing gains, and subsequent finishing performance in 2016, 2017, and 2018. Fescue cultivars evaluated were high-endophyte ‘Kentucky 31,’ low-endophyte Kentucky 31, ‘HM4,’ and ‘MaxQ.’ In 2016 and 2018, steers that grazed pastures of low-endophyte Kentucky 31, HM4, or MaxQ gained significantly more (P<0.05) and produced more (P<0.05) gain/a than those that grazed high-endophyte Kentucky 31 pastures. Gains of cattle that grazed low-endophyte Kentucky 31, HM4, or MaxQ were similar (P>0.05). In 2017, steer gains were similar (P>0.05) among all cultivars. High-endophyte Kentucky 31 pastures had more (P<0.05) available forage than low-endophyte Kentucky 31, HM4, or MaxQ pastures during both 2016 and 2017. Steer gains and gain/acre were similar (P>0.05) between pastures fertilized with nitrogen (N) in the spring and those interseeded …
Including Legumes In Wheat-Bermudagrass Pastures, L. W. Lomas, J. L. Moyer
Including Legumes In Wheat-Bermudagrass Pastures, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
Use of legumes in wheat-bermudagrass pastures did not affect summer cow gains in 2018. Forage availability was greater (P<0.05) where nitrogen (N) alone was used than where crimson clover and ladino clover were used in the Legume system. Estimated forage crude protein (CP) was similar (P>0.05) for the Legume and Nitrogen systems.
Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer
Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
A total of 150 heifer calves grazing smooth bromegrass pastures were used to compare supplementation with 0.5% of body weight per head daily of corn or dried distillers grains (DDG) in 2014, 2015, 2016, 2017, and 2018. Daily gains of heifers supplemented with corn or DDG were similar (P>0.05) in all years except 2018, when heifers supplemented with DDG had greater (P<0.05) gains than those supplemented with corn.
Cattle Preference For Annual Forages, J. K. Farney
Cattle Preference For Annual Forages, J. K. Farney
Kansas Agricultural Experiment Station Research Reports
Many plant species that are available to use as cover crops also have potential as forage for cattle. With this array of options it can be daunting to decide which plants to establish to meet goals as either a cover crop, forage, or for both. Therefore, the purpose of this study was to identify the annual forages fed to cattle in the fall, winter, or summer that cattle preferred. To summarize, grasses were the most highly preferred forage for cattle regardless of grazing period. Low glucosinolate brassicas such as ‘Graza’ forage radish was the most highly preferred brassica that was …
