Extract

In spite of the importance of starch-based feeds for all sectors of the livestock industry, it is difficult to obtain reliable starch estimates. Much of the variation in the accuracy relates to differences in the procedures used. Most starch analyses are enzymatic, relying on the specificity of the enzymes to distinguish the glucose in starch from that in other carbohydrates following gelatinisation. The aims of this study were to compare the accuracy of five different techniques with the aim of selecting the most optimum for future in vitro and in vivo degradation studies.
