Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in pesticides, growth regulator...
Three essays on food security, agricultural productivity, and commodity basis
(University of Missouri--Columbia, 2021)
local, growing season, and regional precipitation, on Missouri corn and soybean basis. We document statistically significant linear and nonlinear basis responses in corn and soybean models for local and growing season precipitation variations. We also...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also humans. Results from our...
The effects of 6-weeks of resistance training on the gut microbiome in young adults with overweight and obesity
(University of Missouri--Columbia, 2022)
and obesity (BMI 25-45 kg/m2) were recruited to participate in this randomized controlled trial. Participants were randomized into 1 of 2 groups: RT (n=17) which participated in a 6-week resistance training program (3 days/week), or control (CT) (n=16) which...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method on surface soil nutrient...
Impact of grazing stockpiled tall fescue of lactating beef cows
(University of Missouri--Columbia, 2006)
Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of ...
Assessing strategies for achieving environmentally sustainable food systems using robust optimization
(University of Missouri--Columbia, 2023)
. For these reasons, it is important to determine the extent to which localized food systems can be realized, including urban agricultural activities, changing food diets, and agricultural conservation practices given the nutritional needs of the population as well...
The effects of exercise and fish oil on oxidative stress
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The purpose of this study was to investigate the effect of four weeks of fish oil supplementation and four weeks of fish oil supplementation and exercise training on measures...
Three essays on innovation, corporate control and household consumption-based asset pricing
(University of Missouri--Columbia, 2021)
Chapter I: Tracking more than 100 billion weekly transactions of two million products at the barcode level from 2007 to 2017, we identify and categorize new products as pioneers, followers and improvers to study corporate ...
Lifestyle treatment in the regression of NASH: insulin resistance, lipid synthesis, and methodological innovation
(University of Missouri--Columbia, 2022)
(liquid chromatography mass spectrometry) were used to track the synthesis of CERs within hepatic tissues of mice consuming 13C3 15N L-serine dissolved in their water and a high fat (60 percent energy, HFD) or a control (low fat, 20 percentE, CD) diet...
Role of preovulatory estradiol in uterine and luteal function
(University of Missouri--Columbia, 2018)
) was examined in Angus heifers having low (5.0 [plus or minus] 0.6; pg/mL n=6) or high (10.2 [plus or minus] 1.0 pg/mL; n=6) preovulatory concentrations of E2 on day 0 (P< 0.0005). In vivo produced embryos (n=5 per heifer) were transferred on day 7...
Phytase : anatomy of an invisible win-win technology
(University of Missouri--Columbia, 2009)
the farmer's knowledge and stated use of phytase using data from a spring 2006 of Missouri and Iowa poultry and livestock farmers. Responses to a number of questions in this survey reveal that knowledge of this win-win innovation is low. It also shows...
Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
Bottomland restoration of native hardwood species provides a variety of benefits to the environment and the landowners. However, when reforesting agricultural floodplains along the Missouri River, high soil pH often causes nutrient deficiencies...
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)

Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
were investigated in beef cattle. Colostrum volume and weight from nutrient restricted dams was 40 percent less compared with control dams. Although gestational nutrition did not affect gestation length or calf birth weight, calves born to control dams...
