Abstract
Dietary starch from feed grains represent the major energy-yielding
sources in diets for large animals and starch effective digestion has a
great impact on animal energy intake for meeting the substantial energy
requirement to improve meat or milk productions. In general, site,
extent and rate of starch digestion are affected by intrinsic and
external factors that can be interrelated and are thus not easily
defined. As a consequence, research to obtain a deeper knowledge on how
starch chemical and structural compositions may affect starch digestion
potential of feed grains and therefore their nutritional value has
progressed recently. The objectives of this review are: (1) to give an
overview on inherent starch primary structures and interactions with
other compounds within feed grains; (2) to discuss factors affecting
starch digestion potential in feed grains; (3) to explore starch
digestion mechanism, and linkages with animal performances, both for
swine and ruminants. The criticism of methods commonly used to estimate
starch digestibility from feed grains for swine and ruminants are also
discussed.
