Abstract
Effect of maize grain treatment on ruminal fermentation and the site and extent of starch digestion in cows
Highlights
The chemical composition and structure of starch in the individual grain types are primary factors which affect the rate and extent of starch digestion in the rumen (French, 1973; Kotarski et al, 1992; Mills et al, 1999a)
The proportion of starch escaping rumen digestion can be altered by changing the source of starch or grain processing method
Maize starch is less degradable in the rumen than wheat, barley or oats starch, up to 40% of maize starch can be found to escape ruminal fermentation (Lebzien et al, 1997; Philippeau et al, 1999a)
Summary
The chemical composition and structure of starch in the individual grain types are primary factors which affect the rate and extent of starch digestion in the rumen (French, 1973; Kotarski et al, 1992; Mills et al, 1999a). The proportion of starch escaping rumen digestion can be altered by changing the source of starch or grain processing method. The quantity of starch digested in the intestines has been discussed by many authors (Nocek and Tamminga, 1991; Huntington, 1997; Mills et al, 1999b; Matthé, 2001; Hindle et al, 2004; Kowalik et al, 2004). The higher resistence of starch against rumen degradation decreased starch digestion in the small intestine (Nocek and Tamminga, 1991; Mills et al, 1999b). Type and degree of grain processing have altered the site of starch digestion and the use of nutrients by the animal (Galyean et al, 1981)
