About This PhD Project

Project Description

Post summary

The student will be part of the UCD/Teagasc/WIT project PigNutriStrat. The aim of this project is to use a multidisciplinary research approach to develop solutions to prevent and manage multifactorial enteric diseases in pigs as a means of reducing the need for antibiotic use. Reducing infection pressure and optimising gut microbiome, immunity and enzyme secretory capacity will be the focus. The student will evaluate pre- and post-weaning management and nutritional strategies as a means of improving lifetime pig health, microbiome and productivity and reducing antibiotic use. The impact of the strategies tested will be evaluated by measuring variables such as pig growth performance, gut health, gut microbiome and immune parameters. The student will also contribute to tasks where specific alternatives to antibiotic feeding approaches are investigated and where hygiene and biosecurity, management, sow and piglet nutrition, health and antibiotic use are linked to economic outcomes. The work will be a combination of animal trials and laboratory analysis with the opportunity to conduct novel interdisciplinary research across areas such as animal nutrition, microbiology, molecular biology and immunology. The student will also receive discipline-specific and generic skills graduate training and will complete a number of courses tailored towards their area, as well as universal modules in areas such as project management, research integrity, academic writing and statistical analysis. The student will be based at Teagasc Moorepark but will be registered at WIT and will have the opportunity to spend time at the WIT and UCD collaborator sites.


Standard duties and responsibilities of the scholarship
• Literature review on pre- and post-weaning nutritional strategies to increase piglet growth and reduce antimicrobial usage
• Preparation of protocols and ethics and licence applications for animal experiments
• Animal work (maintaining records, sampling, weighing etc) on the following project tasks:
• Split suckling and post-partum analgesia to increase colostrum intake
• Supplementary milk for suckling pigs to introduce novel non-antibiotic dietary additives and improve pre- and post-weaning survival, growth and health
• Provision of supplementary liquid milk replacer and/or liquid feed to newly weaned pigs to reduce nutritional stress at weaning
• Low acid binding capacity and protein content diets to help ensure an acidic gastric barrier early post-weaning
• Planning and conducting laboratory analyses on samples from animal trials including gut microbial community (high-throughput 16S rRNA gene sequencing) and resistome (high-throughput shotgun sequencing) analyses, intestinal histology and gene expression analyses, immune assays etc
• Data collation and statistical analysis
• Preparation of reports, publications and conference papers, as well as oral and poster presentations, as required.
