Automating The Milking Process Within A Grass-Based System, John Shortall
Automating The Milking Process Within A Grass-Based System, John Shortall
Theses
The successful integration of automatic milking (AM) and grazing has resulted in AM becoming a feasible alternative to conventional milking (CM) in pasture-based systems. The objective of this thesis was to establish (i) the social, environmental and economic effects of adopting AM technology and (ii) the factors affecting cow traffic, which once the AM is adopted, can also impact on the sustainability of AM. A theme across this thesis is the examination of AM in the context of a seasonal pasture-based milk production system. Electricity and water meters were installed on seven AM fanns. Milking and livestock/^miscellaneous processes were the …
Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell
Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell
Theses
While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year (Health and Safety Authority, 2015). This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector (Health and Safety Authority, 2015). Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to …

An Application Of Time Series Methods To Investigate Eu Dairy Commodity Price Dynamics, Dennis Bergmann
An Application Of Time Series Methods To Investigate Eu Dairy Commodity Price Dynamics, Dennis Bergmann
Theses
Fundamental changes to the common agricultural policy (CAP) have led to greater market orientation which in turn has resulted in significantly changed price dynamics of EU dairy prices. These changed dynamics include sharply increased price variability of EU farm gate milk prices as well EU dairy commodity prices such as butter and Skimmed Milk Powder (SMP). In addition it was expected that EU dairy prices will align to Word dairy prices. This alignment of prices would also see an alignment of volatility levels which were significantly higher for World dairy prices than EU dairy prices. The aim of this thesis …

Comparative Study Of Nutrient Uptake Between Sorghum X Drummond Ii And Cyperus Conglomeratus, A Desert Sedge Native To The Uae, Safaa Alm1ed Alghasyah Aldhanhani
Theses
Sudan grass (Sorghum x drummondii) is commonly grown for the production of animal fodder in the UAE. Cyperus conglomeratus (locally termed ‘Thenda’) is a sedge native to the UAE, and one of the very few plants that colonize soils of shifting desert dunes. The native plant is grazed by camels, and may thus have a potential for animal feed production. While Sudan grass is a mycotrophic plant that normally lives in symbiosis with arbuscular mycorrhizal fungi for facilitation of nutrient uptake, C. conglomeratus is a non-host to these root symbionts. In the desert sedges rhizosheaths comprising of dense coats of …

In Vitro Re Generation And Marker Assisted Evaluation Of Genetic Fidelity In Endangered Tree Species Moringa Peregrina (Forsk) Fiori, Salama Mohammed Al Dhaberi
Theses
Moringa peregrina is a native plant in the United Arab Emirates; it is called “Shua”.It is an endangered species with important nutritive and medicinal properties. It shows high adaptability to the arid condition with short germination time after irrigation. Unmanaged grazing and slow regeneration rate after browsing leads to the endangerment of the species causing erosion in biodiversity. One way to protect these rare species is by multiplying the planting material through tissue culture system and re-introducing at the habitat. Micro propagation is an in vitro method used for plant clonal multiplication under controlled condition. This technique allows conserving the …

Exploration And Implementation Of Innovative Efficiencies/Devices In Beet Processing For Energy Production, Patrick Mcinerney
Theses
The imminent depletion of fossil fuels, as well as concerns for energy security and the obligation to respond to climate change has led to expanding worldwide popularity of Anaerobic Digestion (AD) of energy crops. Sugar beet is a popular AD feedstock due to its favourable characteristics; however it can be quite labour intensive requiring a range of specialist equipment to process the crop prior to undergoing AD. A crucial stage of this process involves the size reduction of beet by a mechanical chopper unit; this pretreatment breaks open the cellulose structure of the crop and increases the surface area available …

Evaluation, Adaptation And Validation Of A Model To Predict Grass Growth In Ireland, Christina Hurtado Uria
Evaluation, Adaptation And Validation Of A Model To Predict Grass Growth In Ireland, Christina Hurtado Uria
Theses
Budgeting grass supply allows producers to minimise the quantity of purchased feed required in the diet of grazing livestock. One tool for managing grass supply could be a mathematical model that can simulate grass growth. The development of such a model would allow better management around the variability of feed supply and help identify feed surpluses and deficits, and therefore increase the accuracy of management decisions. This would be a key feature of profitable milk and meat production systems in the future which will be hugely important as global food demand increases due to population growth. It is forecasted that …

The Suitability Of Ground Date (Phoenix Dactylifera L.) Pits And Ghaf (Prosopis Cineraria L.) Pods As Horticultural Growth Media Or Soil Amendments, Saeed Khalifa Alshaali
Theses
The UAE and its neighboring countries are encountering scarcity of water resources and soil degradation due to salinization. The current over-exploitation of aquifers by the agricultural sector is a major concern for the government. Open field production of forage as a feed for camels, cows and small ruminants requires particularly high amounts of irrigation water. Greenhouse production of fodder might save water, but would require a suitable growth substrate that is readily available in the UAE, and ideally constitutes a palatable fodder itself. The objective of this study was to evaluate the suitability of ground D.pits and G.pods as growth …
