Identifying sow traits for productivity, longevity and welfare
Applications are now CLOSED
Modern sows stay for a short period of time in pig herds with approximately 50% of the herd females being replaced each year. The project aims to identify the gilt traits that aim to predict sow performance in relation to her productive potential, longevity and health and welfare.
Healthy sows are necessary to produce the next generation of pigs and provide them the best start in life. However, modern sows have their lifetime health, welfare and performance affected by having to rear large number of piglets, with litter size outnumbering the number of functional teats, produce high amounts of colostrum and high milk yields in successive cycles. Inadvertently these have profound effects on sow longevity. It has been suggested that, ideally, a sow should complete 8 parities and wean approximately 88 piglets before being replaced. Such situation would result in a sow herd replacing 30% of its females each year. However, sow replacement rate for the last 10 years has remained above 50% in the UK (and NI), with the top 10% UK herds having replacement rates above this average.
Whilst gilts that will enter the breeding herd are fed differently from gilts that are destined for meat production, there is no other selection criteria associated with their selection. The aim of this project is to identify which gilt traits are important to be destined as productive sows to ensure that the productivity, longevity and welfare is not compromised. This will be done by focusing on novel traits measured on gilts by using established and novel technologies.
1 We will interrogate a large dataset generated at AFBI on sow productivity; this process is ongoing. The dataset is based on longitudinal measurements on gilts and sows, for both productive and non-productive characteristics associated with their health and welfare. The dataset will be supplemented by additional novel traits such as udder conformation which will also be generated during the course of the project.
2 We will study the impact of gilt growth and cohort influence on gilt lifetime performance. As well as investigating the role of gilt growth during lactation (i.e, growth rate, weight gain from birth to weaning) the project will be the first to study the impact of the number of male siblings in a litter has on gilts' reproductive performance (the negative influence of in-utero testosterone from male siblings on females' reproductive capacity).
3 We will investigate whether udder health and colostrum quality during first lactation has an influence on piglet performance during lactation. Objective 1 above will have only provided indications about the relationship between these variables and subsequent piglet performance. We will use assessment of novel traits of udder health and colostrum quality, such as visual and morphological assessment combined with thermographic imaging assessment and study its impact on colostrum and milk composition, IgG content and yield, and on piglet pre-weaning performance and health.
4 We will provide recommendations for the traits that need to be included in future selection programmes of gilts in the productive herd.
Skills/experience required: This project would suit a graduate in a biological, veterinary or agricultural discipline with an interest in pig production and sustainability. Specific quantitative skills are not expected but an interest in developing these is important.

Biological Sciences overview
The School of Biological Sciences provides PhD and MPhil (research degree) programmes in subjects ranging from basic biochemistry, molecular genetics and cancer research, to agricultural science, marine ecology and the economic evaluation of ecosystem services and food retailing. If you have a topic or research question in mind, please use the Find a Supervisor link (see Apply tab) to identify the most appropriate member of staff to support your idea. If not, don't worry, we regularly advertise funded projects and there is no harm in browsing our academic staff profiles for inspiration and then contacting whoever seems best: we are very open to applications from suitably qualified people interested in scientific research. In every case, a PhD or MPhil course provides the means of being part of a cutting edge scientific research team and contributing to genuine new discoveries or the development of new methods for practical use. If you cannot study full time, we offer pro-rata part time research degree programmes as well.
There are three broad themes to research at the School:
- Agri-Food Systems and Human Nutrition
- Understanding Health and Disease
- Sustaining Ecosystems and Biodiversity
Agri-Food Systems and Human Nutrition:
This theme focuses on how Agri-Food systems can be better positioned to provide safe and healthy diets and high quality of animal products and support human and animal health in a way that is environmentally sustainable and resilient to climate change.
Underpinning these goals, the disciplinary expertise of the theme integrates basic and applied research from animal health and welfare, nutrition, performance and environmental impact (e.g. greenhouse gas emissions from livestock) to chemical contaminant detection, food microbiology, fraud detection and food systems traceability and transparency.
Supported by underpinning technological expertise in cutting edge molecular, genomic, transcriptomic/proteomic and metabolomic methods, the goal of the theme is to transform Agri-Food systems so that they benefit both human nutrition and health while simultaneously reducing the greenhouse gases emissions from livestock production systems, protecting ecological resources, supporting livelihoods and affordable foods, and upholding social, cultural, and ethical values.
Understanding Health and Disease:
The Understanding Health and Disease research theme covers humans, plants, and animals with research strengths in prevention, diagnostics, surveillance, epidemiology, and treatments. We study how health can be improved through food and nutrition and how diseases can be tackled by understanding their fundamental molecular mechanisms, including those underpinning the biology of pathogens and parasites. Our researchers work in human cancer and genetic diseases, in infections caused by bacteria, fungi, viruses, and parasites, and in how global health and disease will be affected by global warming and climate change.
We recognize that the only way to tackle the problems we face as a society is to take an interdisciplinary approach to our research. This means we have expertise in broad areas including molecular biology, biochemistry, bioinformatics, genomics, transcriptomics, modelling, bioanalytical chemistry, proteomics, metabolomics, microbiology, parasitology, and plant biology. We work internationally with researchers and partners in universities, charities, non-governmental organisations, industry, and government agencies to tackle local and global challenges.
Sustaining Ecosystems and Biodiversity:
This theme covers research in biodiversity and ecosystem services for environments ranging from tropical forests to deep oceans, using field techniques and skills such as wildlife tracking, taxonomy, geostatistics, molecular and genetic ecology, environmental microbiology, microbial ecology, food web analysis, microcosm and mesocosm experiments, and mathematical/computational methods. Within this theme we also study the behaviour and temperament of wild, agricultural or domestic animals and their implications for welfare and ability to respond to environmental change.
Potential research projects include phylogenetic analysis of rare and newly discovered species, examination of ecological interactions in tropical systems, agricultural soils, or marine communities, using state-of-the-art genetic analysis, surveys using drones or satellite tagging, or experiments in tanks and field plots, including careful and ethical examinations of animal behaviour. Projects range from theoretical analysis of stability in ecosystems, through discovery of new species and mechanisms of interaction, or responses to climate change, to the assessment of agri-environment schemes, development of new methods for commercial fisheries management and economic evaluations of conservation measures. Projects very often have an international dimension and include collaboration with other researchers worldwide.

Queen's postgraduates reap exceptional benefits. Unique initiatives, such as Degree Plus and Researcher Plus bolster our commitment to employability, while innovative leadership and executive programmes alongside sterling integration with business experts helps our students gain key leadership positions both nationally and internationally. Career prospects in the biological sciences are exceptionally good. To some extent it depends on the specific topic, of course, but laboratory-based and especially quantitative skills and the proven innovation of a PhD or MPhil are highly sought after. Degrees are very much in demand, both in commercial science and public sector research and development (e.g. drug discovery and development, crop and animal improvements and welfare, sustainable agriculture and resource use, human nutrition and health, animal health, ecological management, food safety and technology, scientific communications, regulation, and many more fields).
Employment after the Course
Graduates have gone on to be professional research scientists, consultants, or hold technical and junior executive positions in commerce and government.
People teaching you
Dr Gareth Arnott
Postgraduate Research Director
School of Biological Sciences
For a PhD you will have a principal and second supervisor who advise your independent studies and will be supported by a wider team from the academic staff - who they are, of course, depends on your project. For further details on any aspect of postgraduate research degrees within the School of Biological Sciences, contact: firstname.lastname@example.org. Research degrees are overseen by the School of Biological Sciences Director of Postgraduate Research, who currently is Dr Gareth Arnott.
Learning OutcomesA postgraduate research degree involves the undertaking of independent research under the guidance of a professional academic supervisory team, typically using the laboratory facilities on offer in one or more of the teams' labs. The student will be expected to develop their own ideas and learn the methods needed to test them empirically and theoretically. This usually involves learning and practising both laboratory (and or field) skills as well as developing a strong theoretical background in the relevant subject.
As well as practical work, all the activities of independent academic scholarship, such as literature searching and critical appraisal, written and verbal communications and academic networking will be developed during a research degree. Independence and innovation will be strongly encouraged, but the student will be supported by regular supervisory guidance and a wide range of courses will also be on offer, both in subject specific skills and generic skills, especially supported by the Graduate School (https://www.qub.ac.uk/graduate-school/).
Students are encouraged to interact with one another and with members of academic staff and postdoctoral scientists to build confidence and informal learning, through a range of ‘research culture’ activities, including peer groups where students get together to discuss topical research papers, or methods, or just chat about their interests.
Course structureResearch degrees vary in length, but typically for a PhD they are three or four years long (full-time) and double that for part-time studies. They follow an annual cycle of progress with formal panel-based appraisals of the progress, the outcome of which is typically practical and academic advice about how to overcome problems encountered and how to move to the next stage. During each year, students are expected to supplement their studies with some tailored courses, ranging from highly specific (e.g. learning to use a piece of apparatus or technique) to generic (e.g. developing oral presentation or leadership skills). Every stage is supported by the supervisory team, augmented by an independent panel of progress monitors as well as the full support of the Graduate School.
Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.
This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.
The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.
Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.
Full-time research students will have access to a desk in a shared office space.
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.

Biological Sciences costs
Students may incur additional costs for small items of clothing and/or equipment necessary for lab or field work
Additional course costs
Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.
Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
