There is an increasing need for information on the involvement of micronutrients in the nutrition of goats under UK conditions and in particular the role of copper. There is particular interest in the interaction of copper (Cu) with molybdenum (Mo) and sulphur (S) which can form complexes which affect Cu absorption from the digestive tract and post-absorption bioavailability to metabolic sites (Gooneratne et al,1989). While there is considerable information in this subject area for sheep and cattle, information on goats is limited. The objective of the work reported here was to investigate the response of Angora goats to a basal diet with adequate Cu and S, and this diet supplemented with Mo at two concentrations.
