Extract

The potential problems concerning the use of manioc, from the processed roots of cassava (Manihot esculenta), have been reviewed by Oke (1978) and Walker (1983). Although current legislation has ensured that in recent years the levels of cyanogenic glucoside in imported cassava have been negligible (Walker, 1985), there is still conflicting evidence on the maximum level of manioc which can be included in pig diets without adverse effects on digestion and performance. In a previous study (Partridge, 1985), 300 g manioc per kg tended to increase the proportion of energy apparently absorbed from the large intestine compared with lower levels. This may have been partially responsible for some of the digestive upsets found with young pigs by O'Grady and Hanrahan (1979). Evidence of the effect of manioc on performance can be misleading due to palatability problems and therefore lower food intakes (Müller, Chou and Nah, 1975; Papodopoulos, Ziras and Kalaissakis, 1983).
