The growing need to diversify animal production in the UK has Increased the interest in indigenous fibre production. Mohair production from Angora goats 1n this country dates back as recently as 1981 with the Importation of 15 Angora does and 3 bucks from New Zealand (Ryder, 1987). To date this production remains a very small enterprise producing less than 0.2% of the world's mohair production (Fisher, 1989) and is compared with an estimated 40% of the world's mohair Imported annually in the UK, valued at approximately £35 million (Fisher, 1989).

There is relatively little information available concerning the nutritional requirements of British Angora goats in relation to mohair production. The objective of the present study was to investigate the effects of feeding basal diets supplemented with Saccharomyces cerevisiae (Yea -Sacc, Alltech, Europe) and additional protein on growth performance, selected blood metabolites and fibre (mohair) growth 1n Angora goats.
