Research Interests

Nutrition and production of pigs and poultry

The overall aim of my research is to develop feeding systems which enhance animal health, performance and meat quality in a sustainable manner. This research requires a fundamental understanding of the underlying physiological, metabolic and genomic responses to nutrients so that mechanisms already existing within the animal may be triggered to respond in an optimal way. Two critical periods in the pig’s life are immediately after birth and immediately after weaning. The latter is of particular importance at present following the recent ban on in-feed antibiotic growth promoters which were used routinely in weaner feeds prior to 2006. This research involves defining fundamental changes in the pig that help it to be successful and how these may be stimulated by nutrition. A number of factors influence piglet success following weaning:

Sow and litter
  • Comparing piglets produced in our indoor versus our outdoor facilities we found that rearing environment affects both survival and performance. Can we use nutrition to equalise environment effects?
  • Certain feed additives e.g. zinc oxide, help pigs to resist disease. Can we create a similar response without using a heavy metal?
  • Another area we are investigating is the voluntary feed intake of the weaned animal since, unsurprisingly, pigs which eat well post weaning do better than those which do not, but what makes some pigs eat more than others at this time? We have developed a group feeding recording system to help us answer this question.

Other areas currently under investigation are:

  • Role of butyrate in stimulating gut development
  • Mode of action of ZnO in controlling pig diarrhoea
  • Developing sustainable alternatives to therapeutic use of heavy metals in pig diets
  • Feeding for enhanced meat quality (with University of Bristol)
  • Genomics of gut development

Funding for these projects currently comes from BBSRC, AHDB and industry.
