This thesis reports on investigations into the influence of diet and a bentonite feed additive on blood parameters in the horse, and the effect of a bentonite feed additive on the process of digestion in the dog. In addition, the methodology of scientific research is examined, and reflections of learning experiences arising from contact with the Hawkesbury approach described. A high-concentrate low-roughage diet, consisting by weight of 70% oats and 30% lucerne chaff, when fed to horses was shown to influence blood red cell levels and blood L-lactate levels compared to three diets of equivalent energy content but reduced proportion of concentrate. Other blood parameters measured included pack cell volume, total plasma protein, total and differential white blood cell count. These demonstrated no significant alteration with diet. The inclusion of bentonite feed additive in a kibble and mince diet fed to dogs was demonstrated to improve the digestion of dry matter and organic matter components of the diet compared to the unmedicated control diet. Inclusion of bentonite food additive in the diet was also associated with an improvement in degree of stool formation and reduction in faecal odour. Part B of the thesis documents the learning experience developed from involvement in the Masters program and reflection on the research studies undertaken. A model for improved reductionist research is described. / Master of Science (Hons) (Systems Agriculture)
