Extract

Information on starch degradation is required to promote a more efficient use of energy and protein in dairy cow diets. Several in vitro and in situ methods have been proposed to estimate starch degradability. However, they are not suitable for application in routine analysis as they often require the use of cannulated animals. The objective of this study was to determine starch degradation of cereal grains using a method based on boiling extraction for 30 minutes with αamylase solution. The starch degradation after incubation in sacco for 6 and 24 h was used to evaluate the new method proposed.
