The purpose of this trail was to determine the differences in ability of sheep and goats to degrade roughages.
Twenty-four rumen canulated (d. 25mm) animals, comprising of 6 Merino-, 6 Dorper wethers, 6 castrated Angora males and 6 castrated Boer goat males received the following diets in succession: 100% lucerne (D1); 75% lucerne & 25% straw (D2); 50% lucerne & 50% straw (D3); and 25% lucerne & 75% straw (D4).
Differences in degradability occurred between breeds on the better quality diets (D1, D2), while on the poorer quality roughages (D3, D4) these differences diminished.
These results suggest no major differences between breeds in their ability to degrade fibre in the rumen.
