Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Craig Krogstad

Department of Animal Science: Dissertations, Theses, and Student Research

Improving the digestibility of fiber and our understanding of how to feed it will optimize the ruminants’ niche in our society, which is to convert human inedible products to high quality protein in the form of meat and milk. Neutral detergent fiber (NDF) digestibility has been studied and modeled for decades, but it is increasingly important as livestock production is scrutinized for resource use and sustainability. Increasing the amount of NDF fed and improving models of NDF digestibility will improve sustainability by increasing the precision at which we feed livestock which results in less nutrient and greenhouse gas (GHG) emissions. …

The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1^st study assessed growth deficits in IUGR juvenile lambs and the benefits of treatment with adrenergic and inflammatory mediators. Growth metrics including bodyweight, rate of gain, and crown-rump length were diminished by placental insufficiency-induced IUGR through 2 mo. of age but were recovered by daily clenbuterol or curcumin supplementation. Body composition metrics indicated by bioelectrical impedance, proximate analysis, and loin size revealed that fat-free lean mass, specific muscle group sizes, and protein-to-fat ratios were reduced in unsupplemented IUGR lambs but recovered to or even past controls in clenbuterol-supplemented lambs. From these findings, we conclude that IUGR impairs postnatal …

Soybean Maturity Group And Planting Date Influence Grain Yield And Nitrogen Dynamics, Carrie C. Ortel, Trenton L. Roberts, Kyle A. Hoegenauer, Larry C. Purcell, Nathan A. Slaton, Edward E. Gbur

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Manipulation of soybean [Glycine max (L.) Merr.] maturity group (MG) and planting date will increase the yield of a soybean crop while simultaneously influencing the potential soil-nitrogen (N) credits. Variations in N returned to the soil by soybean can significantly affect the amount of fertilizer-N needed for the subsequent crop. Four soybean MGs (3.5, 4.7, 5.4, and 5.6) were evaluated at optimal and late planting dates in Arkansas. Grain yield was significantly different among MGs in 2016 (P = .0012) and 2017 (P = .0004), with the 4.7 MG consistently yielding the highest at 3,232 kg ha(-1). Plant total aboveground …

Velvet Longhorned Beetle (Trichoferus Campestris (Faldermann), Taryn M. Rodman, Lori R. Spears, Diane G. Alston, Cami Cannon, Kristopher Watson, Joey Caputo

All Current Publications

The velvet longhorned beetle is an invasive wood-boring pest that is native to Asia and Russia. It infests fruit, forest, and ornamental trees, as well as green and dry wood, such as timber and lumber. This fact sheet provides a description, and information on life history, plant hosts, injury symptoms, monitoring, and management.

This is a guide to help first detectors identify invasive insects, including biology, identification, and monitoring.

Bedstraw Eradication Program 2019/2020 - Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Three-horned bedstraw (Galium tricornutum) is a competitive weed that can cause considerable yield loss in crops, and its seeds are contaminants of fodder and grain. The presence of bedstraw requires infested areas to be quarantined whilst a nine-year program is undertaken – six years of herbicide treatments followed by a three-year ‘release phase’.

In 2019/20 the Program reached a major milestone with quarantine restrictions fully lifted from one property and lifted from the arable areas of a second property. This is a major step toward eradicating bedstraw from Western Australia.

Skeleton Weed Program 2019/2020: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

2019/20 saw the Skeleton Weed Program expand its surveillance and control activities, with financial support from the IFS, specifically:

- Landholder incentives for paddock surveillance were increased and made available for surveillance undertaken on reinfested ‘Code 2’ paddocks. These changes were anticipated to enhance the level of surveillance for skeleton weed, enabling plants to be identified and treated and, therefore, reducing the risk of seed-set and spread.

- The IFS covered the cost of chemical for winter spraying undertaken on heavily infested paddocks. It was anticipated that this would help landholders reduce the level of skeleton weed infestation and, in …

Selection Of The Most Appropriate Tillage System Based On Topsis Model With Emphasize On Impact Of Different Tillage Systems On Yield, Ali Mirzazadeh, Razieh Pourdarbani, Salman Fekri

Emirates Journal for Engineering Research

Among the various agricultural operations, tillage alone accounts for 60% of the energy consumed in agriculture. Other concerns, such as soil compaction, time management, economic issues, porosity reduction, moisture storage capacity, as well as a 25% increase in water and wind erosion, has further fueled efforts to improve tillage methods. In this regard, conservation tillage is more considered by experts. This study was conducted to evaluate important indices of wheat production in different tillage methods. Two plots located in Moghan Agro Co. were selected and were divided into four equal 2.8 hectares. Experiments were performed in randomized complete block design …
