Calcium And Magnesium Absorption And Retention By Growing Goats Offered Diets With Different Calcium Sources, Jennifer E. Long, Kenneth P. Coffey, James D. Caldwell, Dirk Philipp, Robert T. Rhein, Ashley N. Young 2016 University of Arkansas, Fayetteville

Calcium And Magnesium Absorption And Retention By Growing Goats Offered Diets With Different Calcium Sources, Jennifer E. Long, Kenneth P. Coffey, James D. Caldwell, Dirk Philipp, Robert T. Rhein, Ashley N. Young

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Calcium addition is necessary in order to balance the high phosphorus concentrations that are characteristic of high-concentrate ruminant diets. However, calcium sources differ in their bioavailability. Our objective was to determine apparent calcium and magnesium absorption and retention in goats offered diets containing different sources of calcium. Spanish-Boer goats (n = 18; 19.6 ± 1.88 kg) were stratified by body weight (BW) and sex and randomized to dietary treatments consisting of Purina Antlermax 16 containing either calcium carbonate (CC), Calmin (CM) or Milk Cal (MC). Goats were adapted to a control, corn-based high-concentrate diet on pasture and then moved to …


Effects Of Intensive Late-Season Sheep Grazing Following Early-Season Steer Grazing On Population Dynamics Of Sericea Lespedeza In The Kansas Flint Hills, J. Lemmon, W. H. Fick, J. A. Alexander, G. W. Preedy, C. A. Gurule, K C. Olson 2016 Kansas State University, Manhattan

Effects Of Intensive Late-Season Sheep Grazing Following Early-Season Steer Grazing On Population Dynamics Of Sericea Lespedeza In The Kansas Flint Hills, J. Lemmon, W. H. Fick, J. A. Alexander, G. W. Preedy, C. A. Gurule, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Sericea lespedeza (Lespedeza cuneata; SL) is a high-tannin, invasive forb in the Tallgrass Prairie ecosystem. In Kansas, sericea lespedeza infests 980 square miles of pasture, primarily in the Flint Hills region. Sericea lespedeza infestations reduce native grass production by up to 92% through a combination of aggressive growth, prolific reproduction, canopy dominance, and chemical inhibition (allelopathy). Herbicides retard the spread of sericea lespedeza, but application is laborious and expensive; moreover, herbicides are lethal to ecologically-important, non-target plant species.

Increased grazing pressure on sericea lespedeza by domestic herbivores may slow its spread and facilitate some measure of biological control. …

Failure Of A Heterologous Recombinant Sca5/Ompb Protein-Based Vaccine To Elicit Effective Protective Immunity Against Rickettsia Rickettsii Infections In C3h/Hen Mice, Sean P. Riley, Marissa M. Cardwell, Yvonne G. Chan, Ludovic Pruneau, Fabio Del Piero, Juan J. Martinez

Faculty Publications

Spotted fever group (SFG) rickettsial species are obligate intracellular tick-borne pathogens that are responsible for important human diseases. Previous reports have demonstrated the feasibility of using recombinant surface cell antigen Sca5/OmpB to elicit protective immunity against homologous challenges using murine models of Mediterranean spotted fever and Rocky Mountain spotted fever. In addition, the feasibility of generating cross-protective immunity against related rickettsial species has also been established, but the molecular basis for these phenomena was not explored. Here, we demonstrate that vaccination of C3H/HeN mice with a recombinant OmpB domain derived from Rickettsia conorii induced high titer humoral immune responses that …


Investigations Into The Cross-Infectivity Of Nematode Parasites Of Cattle And Sheep, Eva Marie Wray 2015 University of Arkansas, Fayetteville

Investigations Into The Cross-Infectivity Of Nematode Parasites Of Cattle And Sheep, Eva Marie Wray

Graduate Theses and Dissertations

The existence of anthelmintic resistance is not singular in parasite species, host species or geographic region. It has become a problem of worldly stature, especially when considering sheep nematodes. Recommendations have been modified from chemical-based control to multipart, managerial intervention. Compared with nematodes of cattle, the worldwide resistance of sheep nematodes to anthelmintic remedies is much more pronounced and urgent. As the resistance to essentially all anthelmintic classes approaches a cautionary level, the implementation of non-chemical controls has grown increasingly essential. Six-6 to 8 month old Holstein steer calves, six-5 month old Katahdin ram lambs and eight-5 month old Suffolk …


Grass Finishing Systems For Lambs, Erin Leigh Smyth 2015 University of Arkansas, Fayetteville

Grass Finishing Systems For Lambs, Erin Leigh Smyth

Graduate Theses and Dissertations

There is strong interest in sustainably produced meat. Grass-fed lamb could fulfill this market by reducing off-farm inputs. The objective was to examine the effect of grass-finishing or minimal supplementation on performance of lambs in the southeastern US. Katahdin lambs born in October 2013 and 2014 and February 2014 were weaned in January 2014/2015 and May 2014, respectively. Lambs were blocked by gender (fall; winter included only ram lambs) and randomly assigned to receive no (NON) or grain co-product supplement (SUP; 15% CP) at 0.5% of BW/d. Lambs were rotationally grazed on predominantly grass. Body weight, fecal egg counts (FEC), …

Volatile Organic Compound Flux From Manure Of Cattle Fed Diets Differing In Grain Processing Method And Co-Product Inclusion, Kristin Hales, David B. Parker, N. Andy Cole 2014 USDA, Agricultural Research Service

Volatile Organic Compound Flux From Manure Of Cattle Fed Diets Differing In Grain Processing Method And Co-Product Inclusion, Kristin Hales, David B. Parker, N. Andy Cole

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Odor emissions from livestock production have become increasingly important in the past decade. Odors derived from animal feeding operations are caused by odorous VOC emitted from the mixture of feces and urine, as well as feed and silage which may be experiencing microbial fermentation. Distillers grains are a by-product of corn grain fermentation used to produce fuel ethanol, and this industry has grown rapidly throughout the U.S. in past years. Therefore, the use of wet distillers grains with solubles (WDGS) in feedlot cattle diets has also increased. The objective of this research was to determine specific VOC emissions from feces …
