Abstract:

Piglets of 60 days old were used as the animal model to evaluate in vivo apparent digestibility of starch of different coarse cereals such as taro, potato, Chinese yam and cassava. Results indicated that starch content varied in different species of coarse cereals. The apparent digestibility of taro and cassava starches in ileal digesta was significantly higher (P＜0.05) than that of potato and Chinese yam starches. The apparent digestibility of starches of all the coarse cereal species in faeces reached up to 99%. These investigations suggest that taro and cassava starches could supply piglets more glucose when digested in small intestine due to higher digestibility. Higher digestibility of potato and Chinese yam starches in feces could be resulted from the co-fermentation of microorganisms in hindgut of piglets.

Key words: coarse starch, pig, digestibility
