Description
| - The aim of this experiment was to improve the washing process during in vitro estimation of degradation rate of starch particles. The knowledge of degradation rate of starch particles in the rumen is needed to enhance micro-bacterial protein synthesis and energy supply for dairy cows. The washout of very small particles of starch (M-fraction) in the rumen prevents determination of its degradation rate in situ. However, it is possible to measure in vitro degradation rate of both a non-washable, potentially degradable fraction (D) and the M fraction. Centrifugation appeared to be a faster, easier and more reliable method to collect the M fraction of various cereal grains compared to filtration. Medium test bags of 50 cm by 33.3 cm were found to be the most effective for collection of M and D fractions in maize, peas and barley. Results obtained with in vitro incubation with amyloglucosidase did not present satisfactory starch degradation curves. Further research will be conducted to improve this technique, or to replace it with an alternative method, such as in vitro incubation in rumen fluid.
