Can Precision Farming Technologies Be Applied To Grazing Management?, S. Mark Rutter Dec 2019

Can Precision Farming Technologies Be Applied To Grazing Management?, S. Mark Rutter

International Grassland Congress Proceedings

In arable farming, precision is used to monitor and manage crop variability. The same precision approach can be used to manage grassland, by using crop sensing, targeted fertilizer/herbicide/pesticide application and forage yield measurement when it is harvested mechanically. An additional challenge in grassland agriculture is developing precision approaches to manage the grazing process. This requires technologies to determine where an animal is, when, what and how much it is grazing which the system then needs to use in conjunction with other sources of information to control where the animal grazes next. This paper reviews the existing technologies in ...


Manipulation Of The Spatial Grazing Behaviour Of Livestock In Extensive Grassland Systems, Derek W. Bailey, Mitch B. Stephenson, Milton G. Thomas, Juan F. Medrano, Gonzalo Rincon Dec 2019

Manipulation Of The Spatial Grazing Behaviour Of Livestock In Extensive Grassland Systems, Derek W. Bailey, Mitch B. Stephenson, Milton G. Thomas, Juan F. Medrano, Gonzalo Rincon

International Grassland Congress Proceedings

Spatial behaviour of livestock is a critical factor in grassland management. Recent and ongoing research suggests that new approaches can be used to manipulate where cattle graze. The combination of strategic supplement placement and low-stress herding can be used to target cattle grazing and potentially may be useful for managing fine fuels. A phenotype to genotype association study of cattle spatial behavior suggests that use of rugged terrain and areas far from water is inherited. Although more research is needed, selection for animals specifically adapted for mountainous terrain or extensive paddocks may be an alternative for managing grasslands in the ...


Case Studies Which Demonstrate The Financial Viability Of Precision Dairy Farming, Ian Yule, Hayden Lawrence, Craige Mackenzie, Carolyn Hedley, Miles Grafton Dec 2019

Case Studies Which Demonstrate The Financial Viability Of Precision Dairy Farming, Ian Yule, Hayden Lawrence, Craige Mackenzie, Carolyn Hedley, Miles Grafton

International Grassland Congress Proceedings

A number of case studies are used to demonstrate the financial viability of precision farming methods for intensively managed pastures. Precision farming has sometimes been criticized as being technology-led where the management goals and desired outcomes are sometimes poorly defined. Case studies presented in this paper demonstrate a strong management approach where appropriate technologies are selected to contribute to the financial success of the farm. The first case study farm has increased milk production by 70% in four years, increased pasture production by 43%, reduced fertilizer costs to 43% of previous levels and has successfully predicted annual production to within ...


Life History And Population Dynamics Of Green Crabs (Carcinus Maenas), Alan M. Young, James A. Elliott Dec 2019

Life History And Population Dynamics Of Green Crabs (Carcinus Maenas), Alan M. Young, James A. Elliott

Biology Faculty Publications

Carcinus maenas (the “shore crab” or “European green crab”) is a very proficient invader (considered to be one of the world’s 100 worst invaders by the IUCN) due to its phenotypic plasticity, wide temperature and salinity tolerance, and an extensive omnivorous diet. Native to Atlantic Europe, it has established two well-studied nonindigenous populations in the northwestern Atlantic and northeastern Pacific and less-studied populations in Australia, Argentina and South Africa. Green crabs are eurythermal and euryhaline as adults, but they are limited to temperate coastlines due to more restrictive temperature requirements for breeding and larval development. They cannot tolerate wave-swept ...


Remediating Soil For Successful Vegetation Establishment Along Nebraska Highways, Shad Mills, Martha Mamo, Walt Schacht, Humberto Blanco-Canqui Dec 2019

Remediating Soil For Successful Vegetation Establishment Along Nebraska Highways, Shad Mills, Martha Mamo, Walt Schacht, Humberto Blanco-Canqui

Nebraska Department of Transportation Research Reports

Vegetation along roadsides is important to prevent soil erosion, provide habitat, and filter water running off the road. Vegetation close to the pavement along highways in Nebraska does not readily establish and persist. It is thought that the sodium and bulk density are the driving factors behind the lack of vegetation. After a construction project the shoulder is seeded into the compacted soil, and during winter salts can accumulate in the soil because of deicing agents being used. The purpose of our study was to determine if the sodium and bulk density are the driving factors of the vegetation cover ...

Connectivity Differences Between Gulf War Illness (Gwi) Phenotypes During A Test Of Attention, Tomas Clarke, Jessie Jamieson, Patrick Malone, Rakib U. Rayhan, Stuart Washington, John W. Vanmeter, James N. Baraniuk

Faculty Publications, Department of Mathematics

One quarter of veterans returning from the 1990–1991 Persian Gulf War have developed Gulf War Illness (GWI) with chronic pain, fatigue, cognitive and gastrointestinal dysfunction. Exertion leads to characteristic, delayed onset exacerbations that are not relieved by sleep. We have modeled exertional exhaustion by comparing magnetic resonance images from before and after submaximal exercise. One third of the 27 GWI participants had brain stem atrophy and developed postural tachycardia after exercise (START: Stress Test Activated Reversible Tachycardia). The remainder activated basal ganglia and anterior insulae during a cognitive task (STOPP: Stress Test Originated Phantom Perception). Here, the role of ...

Cancer Risk Prediction With Whole Exome Sequencing And Machine Learning, Abdulrhman Fahad M Aljouie

Dissertations

Accurate cancer risk and survival time prediction are important problems in personalized medicine, where disease diagnosis and prognosis are tuned to individuals based on their genetic material. Cancer risk prediction provides an informed decision about making regular screening that helps to detect disease at the early stage and therefore increases the probability of successful treatments. Cancer risk prediction is a challenging problem. Lifestyle, environment, family history, and genetic predisposition are some factors that influence the disease onset. Cancer risk prediction based on predisposing genetic variants has been studied extensively. Most studies have examined the predictive ability of variants in known ...


Perivascular Waste Metabolites Clearance In Central Nervous System (Cns), Yiming Cheng Dec 2019

Perivascular Waste Metabolites Clearance In Central Nervous System (Cns), Yiming Cheng

Dissertations

Efficient clearance of interstitial waste metabolites is essential for normal brain homeostasis. Such effective clearance is hampered by the lack of a lymphatic system in the brain, and the cerebrospinal fluid (CSF) is unable to clear large size waste metabolites in the brain. Here, a novel idea that brain arterial endothelium and smooth muscle cells reactivity regulates the clearance of these water-insoluble large size waste metabolites through the perivascular dynamic exchange, and that low dose ethanol promotes this perivascular clearance is proposed.

In Aim 1, the biodistribution of a large size waste metabolite (Amyloid-β protein mimic) in rat perivascular space ...

Agronomy & Horticulture -- Faculty Publications

Shaded perennial agroforestry systems (AFS) are regarded as desirable land‐use practices that improve soil carbon sequestration. However, most studies assume a positive correlation between above ground and below ground carbon without considering the effect of past and current land management, textural variations (silt and clay percentage), and such other site‐specific factors that have a major influence on the extent of soil C sequestration. We assessed SOC stock at various depths (0–10, 10–30, 30–60, and 60–100 cm) in shaded perennial coffee (Coffea arabica L.) AFS in a 17‐ year‐old experimental field at the Centro ...

Growth Of Bali Bulls Fattened With Forage Tree Legumes In Eastern Indonesia: Leucaena Leucocephala In Sumbawa, Tanda Panjaitan, Muhammad Fauzan, H. Dahlanuddin, Michael J. Halliday, H. Max Shelton

International Grassland Congress Proceedings

The contribution of West Nusa Tenggara Province to domestic beef supply in Indonesia is relatively small, however, beef cattle are very important for the livelihoods of smallholder farmers in the region.

Bali cattle (Boss javanicus) are the predominant breed as they are adapted to harsh nutritional conditions, are highly fertile and have low calf mortality (Toelihere 2003). While genetically capable of achieving a growth rate of 0.85 kg/d (Mastika 2003), Panjaitan (2012) identified poor nutrition as a severe limitation to animal growth in traditional village systems. Improving feed quality and supply is vital to increasing growth rates and ...

International Grassland Congress Proceedings

Brazil is a country of continental size, and more than seven million ha are occupied with tropical pasture. Worldwide animal production from tropical pastures is also very significant where Cynodon, Panicum and Paspalum are important genus. These grasses are widely used in the production of cattle, and are growing in importance for sheep production, but their potential for producing quality lamb is not fully known.

The objective of this study was to evaluate the potential of two tropical grasses for finishing lambs in autumn to reduce the seasonality of production of lamb for meat.


Alternative Pasture Development System And Breeding Weight For Beef Heifers, H. A. Lardner, Daalkhaijav Damiran, Steve Hendrick, Kathy Larson Dec 2019

Alternative Pasture Development System And Breeding Weight For Beef Heifers, H. A. Lardner, Daalkhaijav Damiran, Steve Hendrick, Kathy Larson

International Grassland Congress Proceedings

Proper development of replacement beef heifers is critical and needs to be accomplished at lower costs without sacrificing reproductive performance. The current recommendations indicate heifers should reach approximately 65% of mature body weight (MBW) at breeding for successful reproduction (Patterson et al. 1992; NRC 1996). Meeting heifer maintenance and gestation nutrient requirements are getting more economically challenged for beef producers in western Canada. Therefore, producers are moving from drylot development systems where cattle are housed and fed in pens to the adoption of extensive grazing systems (Kelln et al. 2011) in field paddocks. Limited research has been conducted to determine ...

Variation Of Rumen Bacterial Diversity In Steers After The Beginning Of Grazing, Miwa Nakano, Satoshi Haga, Masanori Tohno, Kazuhiro Matoba, Ryuichi Uegaki, Hiroshi Ishizaki

International Grassland Congress Proceedings

Holstein heifers before or after puberty often are herded on public pastures in Japan. The herbage intake and rumen fermentation of grazing heifers that are not adapted for fresh herbage decreases due to a change of feed from stall-fed dried forage to fresh herbage. This limits their performance during the first several weeks on pasture. Thus, the feeding program such as supplementation before and after the beginning of grazing is important. An increase in ammonia concentration and a decline in fibre degradation in the rumen of a heifer (both of which occur simultaneously with low herbage intake and rumen fermentation ...


Forage Systems Effect On Forage-Fed Beef Production, Guillermo Scaglia, Basu Bhandari, Jeffrey M. Gillespie, Jim J. Wang Dec 2019

Forage Systems Effect On Forage-Fed Beef Production, Guillermo Scaglia, Basu Bhandari, Jeffrey M. Gillespie, Jim J. Wang

International Grassland Congress Proceedings

Locally produced forage-finished beef offers high value while enhancing economic, environmental, and social sustainability. It enhances environmental quality and the natural resource base, and makes good use of resources both on and off-farm. On the farm, it makes the most of the ability of cattle to convert grass to meat in a low-input system, making efficient use of solar energy, improving soil nutrient cycling, conserving soil and water, and limiting reliance on non-renewable resources (DeRamus 2004). Although the major causes of increased greenhouse gas emissions are due to population growth and industrialization, agriculture contributes to carbon dioxide (CO2) emissions through ...

Activity, Physiology And Milk Production Of Yaks And Two Different Yak Crossbreds Grazing Himalayan Pasture Sites At 4700 M And 3000 M, Shanker R. Barsila, Naba R. Devkota, Michael Kreuzer, Svenja Marquardt

International Grassland Congress Proceedings

Yaks (Bos grunniens) and crossbreds of yaks with different local cattle breeds are important for the livelihood of local herders in the Himalayas. They are often kept in a system of transhumance comprising the use of different pasture sites for grazing along an altitudinal gradient throughout the year. The animals are moved upwards to the high altitude pastures in spring/early summer and gradually moved downwards in late summer/autumn. Yaks are suitable for very high altitudes as they are especially adapted to low oxygen partial pressure, forage scarcity and cold and harsh environment (Wiener et al. 2003). However, yak-cattle ...

Fatty Acid Metabolism On Pasture- And Feedlot-Finished Cattle, Cuk T. Noviandi, Robert E. Ward, Jong-Su Eun, Dale R. Zobell, Rusty D. Stott, Blair L. Waldron, Mike D. Peel

International Grassland Congress Proceedings

Feeding high-grain diets to finishing beef cattle results in high proportions of saturated fatty acids (SFA) in the beef, which is considered to confer negative impacts on human health. In contrast, pasture-finished cattle produce lower proportion of SFA, greater n-3 and less n-6 polyunsaturated fatty acids (PUFA), and higher conjugated linoleic acids (CLA) compared to high grain-finished beef (Noviandi et al. 2012). Increased n-3 PUFA, especially C18:3 n-3, can reduce the risk of heart disease, hypertension, inflammation, and mammary cancer, and lower cholesterol concentration in blood (De Deckere et al. 1998; Tapiero et al. 2002).

Nitrogen fertilisation can increase ...

Development Of Feeding System Based On Azolla (Azolla Pinnata) And Sheanut Cake (Vitellaria Paradoxa) For Nellore Sheep Reared In Different Production Systems, K. Sarjan Rao, Y. Ravindra Reddy

International Grassland Congress Proceedings

Since protein sources such as ground nut cake and soya bean are too expensive to feed as supplements to livestock in India, steps have been taken to reduce cost by utilizing alternative feedstuffs to replace the traditional sources in ration formulation (Parashuramului et al. 2013). Azolla which is a free-floating nitrogen fixing water fern has a potential to be used as a protein supplement for ruminants (Ahirwar and Leela, 2012). Sheanut cake (Vitellaria paradoxa) which is produced after extraction of fats use in cosmetics and as a cocoa butter substitute in chocolate making, is also a rich in carbohydrates and ...
