Agriculture, Rural Development and Potential for a ‘Middle Agriculture’ in Ireland
(2014)
Macken-Walsh, Aine
Abstract:
Working Paper
This paper gives a brief overview of current farm viability in Ireland and summarises some of the main ‘barriers’ to farm families’ engagement in contemporary rural development programmes. Against this backdrop, the paper discusses the potential of a middle agriculture model for rural development. The capacity of such a model to address some of the economic, social and cultural predicaments of Irish family farms is outlined. The potential of the model is also discussed in terms of how it may respond to contemporary EC rural development policy priority objectives.

Abstract:
End of Project Report
In the early 90’s, a new and novel means (liquid Flex system) of crop fertilisation was launched on the Irish market which was capable of supplying the crop’s total nitrogen, phosphorus, potassium and trace element requirement in liquid form, formulated to meet specific crop requirements. This system included novel chemistry, untested under Irish conditions and with little specific reference in the scientific literature. The chemistry of the liquid Flex system consists of an acid-based material. Stable compounds i.e. urea sulphate, urea phosphate and urea-metal complexes are formed by the reaction of urea with sulphuric acid, phosphoric acid and metal salts, respectively. Interest in these materials has been generated because they possess a number of physical and chemical characteristics, which, in theory, should be beneficial. However, the ability of the Flex system to effectively supply nutrients to the plant has not been researched. A field and greenhous...

Abstract:
End of Project Report
International experience has been that cervical insemination of sheep with frozen-thawed semen usually yields unacceptably low pregnancy rates (10 to 30%). An exceptional case has been Norway where non-return rates in on-farm usage are around 60%. The objective of the work described in this report was to develop an AI procedure for Irish conditions, based initially on Norwegian protocols, using semen from individual rams. Such a procedure would greatly facilitate and enhance genetic improvement programmes for sheep. The work undertaken had two separate aspects:- (i) studies on semen, including processing and freezing methods, laboratory evaluation of semen quality post thawing and the relationship of in vitro evaluation to fertilisation rate in vivo (ii) studies on pregnancy rate following AI in relation to issues such as ram breed effects, effects of synchronisation, operator differences and the role of ewe breed inducing the timing of ovulation and va...

Algal Proteins: Extraction, Application, and Challenges Concerning Production
(2017)
Bleakley, Stephen; Hayes, Maria
Abstract:
Stephen Bleakley is in receipt of a Teagasc Walsh Fellowship (Grant No. 2016073). This work forms part of the BioAlgae project funded by the Teagasc (Grant No. NFNY6889-142).
Population growth combined with increasingly limited resources of arable land and fresh water has resulted in a need for alternative protein sources. Macroalgae (seaweed) and microalgae are examples of under-exploited “crops”. Algae do not compete with traditional food crops for space and resources. This review details the characteristics of commonly consumed algae, as well as their potential for use as a protein source based on their protein quality, amino acid composition, and digestibility. Protein extraction methods applied to algae to date, including enzymatic hydrolysis, physical processes, and chemical extraction and novel methods such as ultrasound-assisted extraction, pulsed electric field, and microwave-assisted extraction are discussed. Moreover, existing protein enrichment methods used in the da...

Abstract:
Context: Current production from natural forests will not satisfy future world demand for timber and fuel wood, and new land management options are required. Aims: We explore an innovative production system that combines the production of short rotation coppice in wide alleys with the production of high-value trees on narrow strips of land; it is an alternative form of alley cropping which we propose to call ‘alley coppice’. The aim is to describe this alley coppice system and to illustrate its potential for producing two diverse products, namely high-value timber and energy wood on the same land unit. Methods: Based on a comprehensive literature review, we compare the advantages and disadvantages of the alley coppice system and contrast the features with well-known existing or past systems of biomass and wood production. Results: We describe and discuss the basic aspects of alley coppice, its design and dynamics, the processes of competition and facilitation, issues of ecolo...

Alterations in hepatic miRNA expression during negative energy balance in postpartum dairy cattle
(2014)
Fatima, Attia; Waters, Sinead M.; O'Boyle, Padraig; Seoighe, Cathal; Morris, Dermot G.
Abstract:
Background Negative energy balance (NEB), an altered metabolic state, occurs in early postpartum dairy cattle when energy demands to support lactation exceed energy intake. During NEB the liver undergoes oxidative stress and increased breakdown of fatty acids accompanied by changes in gene expression. It is now known that micro RNAs (miRNA) can have a role in mediating such alterations in gene expression through repression or degradation of target mRNAs. miRNA expression is known to be altered by metabolism and environmental factors and miRNAs are implicated in expression modulation of metabolism related genes. Results miRNA expression was profiled in the liver of moderate yielding dairy cattle under severe NEB (SNEB) and mild NEB (MNEB) using the Affymetrix Gene Chip miRNA_2.0 array with 679 probe sets for Bos-taurus miRNAs. Ten miRNAs were found to be differentially expressed using the ‘samr’ statistical package (delta = 0.6) at a q-value FDR of <...

Alternative Enterprises: Economic Performance and Viability.

Connolly, Liam
Abstract:
End of Project Reports
The economic environment for Irish farming has changed dramatically over the last two decades. The reform of the Common Agricultural Policy with the introduction of quotas on the main farm enterprises in the 1980’s, forced farmers to consider diversifying into new or “alternative” uses for their land, buildings and other resources. The main objectives of this study were to identify the factors affecting the profitability and expansion in the main alternative livestock enterprises and also in rural tourism. Investment costs, returns on investment and market prospects for these new enterprises were investigated. The main livestock enterprises considered were deer, sport horses, dairy goats and free range poultry.

Alternative uses for co-products: Harnessing the potential of valuable compounds from meat processing chains
(2017)
Mullen, Anne Maria; Álvarez García, Carlos; Zeugolis, Dimitrios; Henchion, Maeve; O'Neill, Eileen; Drummond, Liana
Abstract:
Opportunities for exploiting the inherent value of protein-rich meat processing co-products, in the context of increased global demand for protein and for sustainable processing systems, are discussed. While direct consumption maybe the most profitable route for some, this approach is influenced greatly by local and cultural traditions. A more profitable and sustainable approach may be found in recognizing this readily available and under-utilised resource can provide high value components, such as proteins, with targeted high value functionality of relevance to a variety of sectors. Applications in food & beverages, petfood biomedical and nutrition arenas are discussed. Utilization of the raw material in its entirety is a necessary underlying principle in this approach to help maintain minimum waste generation. Understanding consumer attitudes to these products, in particular when used in food or beverage systems, is critical in optimizing commercialization strategies.

Alternatives to formic acid as a grass silage additive under two contrasting ensilability conditions
(2014)
Lorenzo, B. Fernandez; O'Kiely, Padraig
Abstract:
The effects of formic acid and four alternative additives on silage fermentation, in-silo DM losses and aerobic stability were compared in an experiment using both difficultto- ensile (DIFF) and easier-to-ensile (EASI) herbages. Both were ensiled in laboratory silos with either no additive or following the application of formic acid (FA; 850 g/kg) at 3 mL/kg herbage, Add-SaFeR® (ATF1) and GrasAAT® (ATF2), both based on ammonium tetraformate, at 4 mL/kg herbage, an antimicrobial mixture (MIX; potassium formate, sodium disulfite and sodium benzoate) at 3 g/kg herbage, or Ecosyl (LAB; Lactobacillus plantarum) at 3 mL/kg herbage. There were four replicates per treatment and the silos were stored for 132 days. DIFF silage made without additive was poorly fermented. All additives increased the extent and improved the direction of DIFF silage fermentation, and reduced in-silo losses. However, MIX did not reduce butyric acid concentration and increased the extent of aerobic deterioration. L...

Abstract:
There has been a move away from vaccines composed of whole or inactivated antigens toward subunit-based vaccines, which although safe, provide less immunological protection. As a result, the use of adjuvants to enhance and direct adaptive immune responses has become the focus of much targeted bovine vaccine research. However, the mechanisms by which adjuvants work to enhance immunological protection in many cases remains unclear, although this knowledge is critical to the rational design of effective next generation vaccines. This study aimed to investigate the mechanisms by which alum, a commonly used adjuvant in bovine vaccines, enhances IL-1β secretion in bovine peripheral blood mononuclear cells (PBMCs). Unlike the case with human PBMCs, alum promoted IL-1β secretion in a subset of bovine PBMCs without priming with a toll-like receptor agonist. This suggests that PBMCs from some cattle are primed to produce this potent inflammatory cytokine and western blotting confirmed the pre...

Abstract:
Deposition of urine and dung in pasture-based livestock production systems is a major source of ammonia (NH3) volatilization, contributing to the eutrophication and acidification of water bodies and to indirect nitrous oxide emissions. The objectives of this study were to (i) measure NH3 volatilization from dung and urine in three seasons, (ii) test the effect of spiking urine with the nitrification inhibitor dicyandiamide (DCD) on NH3 volatilization and (iii) generate NH3 emission factors (EFs) for dung, urine and urine + DCD in temperate maritime grassland. Accordingly, simulated dung, urine and urine spiked with DCD (at 30 kg DCD/ha equivalent rate) patches were applied to temperate grassland. Treatments were applied three times in 2014 with one measurement of NH3 loss being completed in spring, summer and autumn. The NH3-N EF was highest in spring, which was most likely due to the near absence of rainfall throughout the duration of loss measurement. The EFs across the experiment...

Abstract:
Fertilizer nitrogen (N) contributes to ammonia (NH3) emissions, which European Union member states have committed to reduce. This study focused on evaluating NH3-N loss from a suite of N fertilizers over multiple applications, and gained insights into the temporal and seasonal patterns of NH3-N loss from urea in Irish temperate grassland using wind tunnels. The fertilizers evaluated were calcium ammonium nitrate (CAN), urea and urea with the N stabilizers N-(n-butyl) thiophosphoric triamide (NBPT), dicyandiamide (DCD), DCD+NBPT and a maleic and itaconic acid polymer (MIP). 200 (and 400 for urea only) kg N/ha/yr was applied in five equal applications over the growing season at two grassland sites (one for MIP). Mean NH3-N losses from CAN were 85% lower than urea and had highly variable loss (range 45% points). The effect of DCD on NH3 emissions was variable. MIP did not decrease NH3-N loss, but NBPT caused a 78.5% reduction and, when combined with DCD, a 74% reduction compared with u...

Abstract:
End of Project Report
This project was supported jointly by the Commission of the European Community (Contract AIR 3-CT94-1953) and by Teagasc, Agricultural Research and Development Authority.
The overall objective of the EU funded project was to evaluate the ability of ammonium thiosulphate (ATS) to act as an inhibitor of urease and nitrification processes and as a source of plant nutrient S when added to solid and liquid fertilisers and to slurries. These initial experiments have shown the need for further research on (a) applying ATS directly to the soil rather than to the herbage surface, and (b) adding ATS to the slurry in the storage tank simultaneously with slurry excretion.

A grazing trial using beef animals (mean weight 260 kg) was used to determine optimum soil phosphorus levels for dry stock farming. · The trial commenced in 1968. There were three fertiliser P treatments, 0, 15 and 30 kg P/ha applied annually. There were two stocking rates, 3300 and 2400 kg liveweight at turn out, respectively. Animals were rotationally grazed around six paddocks per treatment and stocking rates were reduced in June and September to match feed supply. The trial continued until 1998. ¸ Nitrogen was applied at a rate of 220 kg/ha per year to all treatments. ¹ Liveweight gains/ha/year were monitored annually. Soil P levels were monitored by sampling to 10 cm depth. º The distribution of phosphorus in the soil was recorded by analysing P levels at various depths from 0-2 mm to 100 cm.

Abstract:
End of Project Report
This report summarizes research that the author undertook as part of his doctoral studies in the Department of Agricultural Economics at the University of Missouri- Columbia.† The policy environment within which the Irish beef sector operates is changing such that the demand for Irish beef will increasingly be of a market rather than a policy determined nature. This changing environment makes knowledge concerning the demand for Irish beef important to understanding the economic prospects of the sector. The objectives of this research were thus two fold. The first objective was to investigate the demand for Irish beef in the UK. The second objective relates to how such consumer demand models are econometrically estimated. The empirical results show that the demand for beef in general in the UK is not price elastic and that the demand for Irish beef in the UK is price inelastic. The expenditure elasticity of demand for beef in the UK is also inelastic. The im...

An economic analysis of the Irish milk quota exchange scheme.

Hennessy, Thia; Lapple, Doris; Shalloo, Laurence; Wallace, Michael
Abstract:
In Ireland, the trade of milk quota is subject to regional restrictions and a large variation in quota prices between regions has caused some controversy. This article investigates this issue by analysing the functioning of the Irish milk quota exchange market. For this purpose, the economic value of milk quota is estimated using an optimisation framework. The estimated values are then compared to milk quota prices paid at the exchange market. The analysis reveals that quota is undervalued in the border, midlands and west and south-west regions, while milk quota is overvalued in the east and south regions. This implies that farmers in certain regions overpay for additional quota, while other farmers secure good value for their quota investments. The paper concludes by discussing that the identified regional differences are only partly explained by economic and production factors.

Abstract:
Pigs reared in intensive farming systems are more likely to develop damaging behaviours such as tail and ear biting (EB) due to their difficulty in coping with the environment and their inability to perform natural behaviours. However, much less is known about the aetiology of EB behaviour compared to tail biting behaviour. Application of new intervention strategies may be the key to deal with this welfare issue. The discipline of Precision Livestock Farming (PLF) allows farmers to improve their management practices with the use of advanced technologies. Exploring the behaviour is the first step to identify reliable indicators for the development of such a tool. Therefore, the aim of this study was to develop an ethogram of biter and bitten pigs during an EB event and to find potential features for the development of a tool that can monitor EB events automatically and continuously. The observational study was carried out on a 300 sow farrow-to-finish commercial farm in Ireland (Co. ...

For the laboratory studies, soils were sampled at four different locations throughout Ireland. These soils were subjected to soil classification and hydraulic conductivity tests. Since this series of experiments had been conducted using water as the permeating fluid, further investigation was undertaken to examine the effect of animal slurry flowing through a soil liner. It was concluded that the presence of suspended solids in the slurry had a pronounced sealing effect on the soil liner, significantly reducing the effective permeability of the soil due to the deposi...

Since 1985 the rate of genetic improvement increased markedly to about 1.5% per year in 1992 (Coffey, 1992). This high rate of genetic progress has mostly been achieved through the importation of North American and European genetics. The relative merit of these sires has been obtained from the performance of their progeny in systems of milk production which differ greatly from those operated in Ireland. The term “high genetic index” (HGI) is used to describe a cow, which as a result of selection, is generally predisposed to produce significantly more milk than a cow of lower merit status. Studies from New Zealand have shown that cows of high “genetic index” at pasture, produce more milk (20 to 40%), consume more herbage (5 to 20%), were more efficient ...
