This might influence the rate and extent of starch degradation in the rumen. Most commonly, degradation characteristics are studied in situ, but this technique is time consuming and labour intensive and thus hardly suitable for screening of a large number of genotypes. Because starch is the dominant fermentable substrate in the maize grain, in vitro gas production characteristics may be suitable for a fast and simple prediction of in situ starch degradation. The objectives of this study therefore were 1.) to characterize the in situ starch degradation of different maize genotypes, and 2.) to compare the in situ degradation characteristics with in vitro gas production kinetic data and to calculate multiple linear prediction equations.</span></span></p>
