Optimising production systems for organic pig production (OF0169)

This is the final report of Defra project OF0169. There is a more comprehensive Executive Summary at the start of the attached main report. The overall objective of this project was to generate the scientific and financial information necessary to facilitate increased production of pigmeat on existing organic farms, and the conversion of conventional farms to this organic production. Information was collected through a series of experiments focusing on the effects of genotype, management and nutrition. The study was conducted on commercial organic pig farms, supported by literature searches, financial appraisal, and survey data collection. Organic production standards favour traditional breeds of livestock in preference to ‘improved’ genotypes, which may be less suited to the more extensive production systems. An experiment was carried out to compare performance, health and welfare of three different genotypes managed organically. These genotypes were chosen to represent different breeding strategies - British Saddleback (S), a pure-bred, traditional genotype; PIC Camborough 12 (C12), an improved modern genotype; and Saddleback x Duroc (SD) sow, suitable for ‘criss-cross breeding’ system by smaller organic farms. The modern improved genotypes of sows produced higher litter sizes than their more traditional counterparts, although the numbers of pigs weaned were similar across the genotypes studied. The results indicated that all three breeding strategies can be successfully adopted in organic production systems, and that choice of sow breed should depend on the ability of the farm to manage prolific sows, the implications for slaughter pig performance, and market requirements. A factorially designed experiment was carried out to investigate the effects on performance and carcass quality of three different genotypes of growing pig, three feeding systems and two housing systems. Overall, there were few significant treatment effects on product quality. In a further experiment, the herbage intake of growing pigs maintained at pasture was quantified. The results showed that, when offered a cereal- based concentrate ad libitum, the herbage intake of growing pigs from a good quality grass/clover sward contributed <5% to daily organic matter consumption. In these circumstances, modification of concentrate composition would not be appropriate. To facilitate efficient feed use in organic pig production, a ‘Feed Handbook’ (publication C3) was compiled, printed and made available to UK organic farmers. The effect of paddock management on the ranging behaviour of sows was also studied in a two by three factorial design, involving three sow genotypes. Two commercially applicable paddock management strategies were established: a) ‘Rotational’ (R) where a group of up to 6 sows was relocated to clean ground every four months, and b) ‘Set stocked’ (SS) where a group of up to 6 sows was relocated to clean ground every twelve months. Results suggest that during wet periods, the R paddocks may be advantageous as the pigs are moved off damaged pasture, whereas in drier periods, the SS paddocks maintain grass cover for longer than R and therefore incur less labour for moving without significant pollution risk. Pigs in the SS paddocks do use the further portions of the field, but this may require management manipulations to achieve satisfactory grass usage and distribution of excreted nutrients. In a survey conducted between August 1999 and April 2002 on the commercial organic farms, the main welfare issues reported related to keeping stock clean and dry in periods of high rainfall, managing Porcine Dermatitis and Nephropathy Syndrome and Postweaning Multisystemic Wasting Syndrome (PDNS/PMWS) within their herd, and recruiting and retaining good quality personnel. Mange and lice were the highest-ranking current health concerns, and post-mortem reports of endo-parasitism was the highest-ranking historical health concern. Two of the five farms surveyed reported problems with scouring in young pigs probably due to Coccidia, which may pose a significant risk in organic systems. Data collected on physical performance, capital investment and operating costs were used to establish bench-mark production levels for organic pig herds, the cashflow implications of establishing an organic pig herd, profitability, and sensitivity to movements in productivity, costs and prices. This showed the potential for profitability, which was vulnerable to price fluctuations. Information was disseminated widely through farmer conferences and talks at national conferences, scientific papers, conference proceedings, technical and press reports

Base of Pyramid (BoP) is nowadays one of global management’s top issues. Although several studies were focused on developing economies and their markets behaviour, very few have worked on the internal organization dramaBoP, developing economies, strategy, value chain

Ethnic Politics and National Integration in Nigeria: An Impact Analysis

Since Nigeria s independence in 1960 Nigerian politics has been bedeviled by ethnic politics as a result of ethnic polarization and sentimental coloration of all national issues This problem has been one of the major factors inhibiting national integration and national development in Nigeria Nigerian politics is tainted with ethnic sentiments and politically induced disharmony Ethnic politics has been one of the factors responsible for low productivity and the general poor socio - economic development in Nigeria The major focus of this study is to examine the challenges of ethnic politics in Nigeria as it relates to national integration with a view to critically evaluating the impact Secondary data was used to gather relevant information for this study One finding of the study is that ethnic politics was deliberately introduced and propagated in the Nigerian political system by the British colonial government through its divisive divide and rule policy to actualize colonial and imperialist economic and political objectives The situation has not abated in spite of several attempts to redress it through state creation and the Federal character principl

Rethinking Prebendialism in Nigeria’s Socio-Political Process: The Implication for Democratisation of South-South Region

This study examines Godfathers impacts in the Nigerian socio-political process and the implication on the nascent democracy in the South-South Region The design was exploratory and the study was descriptive combining secondary data from books and the internet The study uncovered that godfathers were patron-occupying state offices as pre-bends They became the gate-keeper determines the development initiative to be followed and employed benefactors of privileges This study s findings also indicated that the state s character and the natures of politics in Nigeria had impacted negative values which now threatens the very foundation of the country s blossoming democracy leading to unhealthy rivalry and competition among godfathers to have control over state powers using their favoured political godsons and denies the electorates of their right to elect a generally acceptable candidate This act renders no free and fair elections Also the struggle for control of state powers has resulted in electoral violence in Nigeria either before or during or after election

Participatory Budgeting in Nigerian Local Government Administration: A Panacea for Rural Development in Nigeria

Government annual budget is a public proclamation of its projected and actual expenditures which provide vital evidence of where a State sets its priorities Therefore this article seeks to show how the participatory budgeting offers citizens a large opportunity to learn about government operations and to deliberate debate and influence the allocation of public resources in the local government councils Through a descriptive historical analysis this study shows that the local government s current budget processes reveal that citizens have no understanding of what the local government council is committing itself to in its policy declarations and what it actually does in its budgetary allocations The extremely complicated technical and esoteric nature of the budget-making process and documents does not allow citizens to participate to have any say in it or to monitor the process it is the position of this paper that participatory budgeting programs are implemented at the behest of governments citizens nongovernmental organizations NGOs and civil society organizations CSOs to allow citizens to play a direct role in deciding how and where resources should be spent It is a tool for educating engaging and empowering citizens and strengthening demand for good governance It also enhanced transparency and accountability More so the study revealed that participatory budgeting helps reduce government inefficiency and curb clientelism patronage and corruption Besides recommending encouragement of citizen s participation in budgeting community-based organizations the civil society and the media should be involved and be stimulated to play the role of a conscience keeper on behalf of the poor and marginalized in the societ

Bioconjugation of peptides to biomaterial surfaces is one of the strategies that may overcome these limitations. Herein, norbornene-chitosan (NorChit) microspheres were engineered to react with thiolated peptides by thiolene “photoclick” chemistry. NorChit microspheres were produced by spray drying and crosslinked with dithiothreitol (DTT) to prevent their solubilization. Microspheres with a diameter of 5 ± 2 µm showed round and smooth morphology with pockets over the surface that could be related with hydrophobic interactions between internal norbornene groups. Thiol-ene bioconjugation carried out using a fluorescent model peptide, showed a yield of 45%, whereas using the peptide but without UV exposure indicated a maximum of peptide adsorption of 30%. Altogether, NorChit microspheres show the potential for carrying bioactive peptides, which may open avenues for AMP activity onto harsh environments in the bod
