Research Interests

Over the past five years my research has been focussed on:

  1. improving the nutritive value of fibre-based feedstuffs for horses by using fibrolytic enzyme treatments and fibrous by-products, and
  2. investigating the effect of high-starch and high-fructan diets on the large intestinal environment of the horse. 

The foregoing has required the development of a) in vitro techniques for estimating the in vivo digestibility of feedstuffs for horses and for assessing the effect of extraneous treatments such as fibrolytic enzymes and probiotic supplements, and b) methodologies for detailed chemical analyses of fibrous feedstuffs as a means of predicting their in vivo digestibility. 

My research has been aimed at improving gut health in equids, and recently, this has become more focussed on the quantification of the microbial population in the gastrointestinal tract of equids using modern molecular techniques, with work directed towards quantification of candidate bacteria in the large intestine of the horse.

Achievements to date include:

  1. Development of in vitro gas production technique to estimate fermentation in the large intestine of the horse
  2. Evaluation of extraneous treatments (such as fibrolytic enzymes and probiotics) for improving fibre digestibility in equids.
  3. Investigation of the effect of high-NSC diets on the large intestinal environment in equids.
  4. Development of novel molecular techniques to quantify candidate bacteria in the large intestine of equids.
