Effects Of Supplementing Corn Silage To Fall-Calving Heifers And Cows Grazing Bermudagrass And Calf Performance And Physiology, J. Wyatt L. Banks, Jaymelynn K. Farney, Karol E. Fike, Jason M. Warner

Kansas Agricultural Experiment Station Research Reports

The objective was to test the effect of supplemental feeding on cows grazing bermudagrass pastures on cow-calf performance and pasture management. In a completely randomized design, (n = 24) primiparous and multiparous Angus-based cross cows were allocated to bermudagrass pasture with one of two levels of supplemental feeding (non-supplemented or supplemented at 1% of BW on a DM basis of corn silage). Each treatment consisted of (n = 4) pastures stocked with three cows of different ages, a young (first-calf heifer), middle-aged (3-5 yrs.), and old (≥ 6 yrs.) cow, each averaging 155 ± 14 d of gestation at turnout. …

Evaluation Of Grazing Options During Summer For Growing Heifers – Year 3, Jaymelynn K. Farney, Larissa Muniz, Harley Allen Jan 2023

Evaluation Of Grazing Options During Summer For Growing Heifers – Year 3, Jaymelynn K. Farney, Larissa Muniz, Harley Allen

Kansas Agricultural Experiment Station Research Reports

Developing methods to provide high quality forage through most of the year is important for cattle operations. The purpose of this study was to determine forage management options to offset the summer “slump” with fescue. Four grass pasture treatments (10 pastures total; 4 acres each) were used in a completely randomized design and stocked with growing heifers (n = 49; initial wt 461 ± 65 lb). Pasture treatments consisted of novel fescue (FES), crabgrass (CRAB), bermudagrass (BERM), and sorghum-sudan interseeded into novel fescue (SS-FES). Heifers were weighed and they grazed pastures from May to September. Heifers on FES were continuously …

Evaluation Of Grazing Options During Summer For Growing Heifers, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Developing methods to provide high quality forage through a majority of the year is important for cattle operations. The purpose of this study was to determine forage management options to offset the summer “slump” with fescue. Four grass pasture treatments (10 pastures total; 4 acres) were used in a completely randomized design and stocked with growing heifers (n = 47; initial wt 419 ± 20 lb). Pasture treatments consisted of novel fescue (FES), crabgrass (CRAB), bermudagrass (BERM), and sor­ghum-sudan interseeded into novel fescue (SS-FES). Heifers were weighed and grazed FES/SS-FES pastures April to November (213 d) or CRAB and BERM …


Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch Dec 2020

Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch

Masters Theses

Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …


Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer Jan 2020

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 400 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, 2018, and 2019. 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, 2012, and 2019. Daily gains of steers that grazed wheat-crabgrass were greater …


Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas Jan 2020

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas

Kansas Agricultural Experiment Station Research Reports

Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in a bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod, and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen). Use of legumes in wheat-bermudagrass pastures did …

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 Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

MaxQ tall fescue, a wheat-bermudagrass double-crop system, and a wheat-crabgrass double-crop system have been three of the most promising grazing systems evaluated at the Kansas State University Southeast Agricultural Research Center in the past 20 years, but these systems have never been compared directly in the same study. The objective of this study was to compare grazing and subsequent finishing performance of stocker steers that grazed these three systems.

Methane Prediction By Nutrient Profiles In Ruminal Continuous Cultures Fed An All Forage Diet Of Bermudagrass Or Annual Ryegrass, Kaylin Young Dec 2013

Methane Prediction By Nutrient Profiles In Ruminal Continuous Cultures Fed An All Forage Diet Of Bermudagrass Or Annual Ryegrass, Kaylin Young

All Theses

Extensive research has been done on the effect of diet on rumen methane (CH4) production, and on developing equations to accurately predict CH4 in cattle. However, the majority of this research has been gathered from feedlot cattle or cattle fed a total mixed ration (TMR). To date, no studies have examined nutrient correlations with CH4 when feeding an all pasture diet of warm season or cool season grasses. This study included two in vitro experiments, one with a warm season forage and one with a cool season forage to see which nutrient characteristics of each forage best correlated with CH4 …

Evaluation Of Internal Markers For Predicting Digestibility And Fecal Output By Cattle Fed Bermudagrass Hays Of Varying Quality, Juvenal Kanani

Graduate Theses and Dissertations

The potential of in situ rumen undegradable dry matter (RUDM), indigestible neutral-detergent fiber (INDF), indigestible acid-detergent fiber (IADF), acid-detergent insoluble ash (ADIA), alkaline-peroxide lignin (APL), and acid-detergent lignin (ADL) to predict digestibility (DMD) and fecal output (FO) by cattle fed bermudagrass [Cynodon dactylon (L.) Pers.] hay-diets categorized by their low (L), medium low (ML), medium high (MH), or high (H) CP concentrations (79, 111, 131, and 164 g/kg DM, respectively) was evaluated. The second objective was to evaluate the effects of time (0600, 1200, 1800, and 2400 h) of fecal sampling on the prediction of FO and DMD. A replicated …
