About the position

Research Context

This PhD position, hosted at Queen’s University Belfast, focuses on developing novel feeding strategies designed to reduce ammonia emissions from ruminant livestock while simultaneously improving animal productivity. Ammonia emissions from agriculture, particularly from ruminants, are a significant environmental concern, contributing to air pollution and nitrogen deposition. The project aims to address this challenge by exploring dietary interventions, feed additives, or management practices that alter nitrogen utilization in the rumen. The ultimate goal is to recommend feeding approaches that lower environmental impact without compromising growth, milk yield, or overall production efficiency. The research will combine knowledge of animal nutrition, rumen microbiology, and emission measurement techniques.

Candidate Profile

Applicants should hold a strong academic background in animal science, veterinary science, or a closely related discipline. Practical laboratory experience is essential, particularly in areas such as feed analysis, rumen fermentation assays, or quantification of gaseous emissions. Familiarity with ruminant metabolism and experimental design is highly desirable. The successful candidate will be expected to conduct independent research, manage data collection, and contribute to scientific publications.

Duties & Research Activities

The PhD researcher will design and execute feeding trials or in vitro experiments to test candidate strategies. Duties include formulating experimental diets, monitoring animal performance, measuring ammonia emissions, and analyzing biological samples (e.g., rumen fluid, blood, milk). The work will involve laboratory techniques such as gas chromatography, spectrophotometry, or nitrogen balance studies. Collaboration with academic supervisors and industry partners is anticipated, and the candidate will participate in training programs and conferences.

Eligibility

Candidates must meet the academic entry requirements for PhD study at Queen’s University Belfast. A minimum of an upper second-class honours degree (or equivalent) in animal science, agricultural science, or a relevant field is required. Demonstrated laboratory experience is mandatory. No specific funding details or salary information are provided in the source; interested individuals should consult the official advertisement for stipend and tuition fee arrangements.

How to Apply

Application instructions and deadlines are available through the official Queen’s University Belfast postgraduate admissions portal. Prospective applicants are advised to review the full vacancy description on the university website and submit the required documents, including a CV, academic transcripts, and a statement of research interest.
