Method for measuring fiber digestibility |
摘要 |
Described is a method of measuring fiber digestion in ruminants and calibrating spectrophotometers using the measured fiber digestion values. The method includes the steps of harvesting rumen fluid from at least one ruminant animal and combining the rumen fluid with a primer composition comprising a carbohydrate. The rumen fluid and carbohydrate are then incubated in a sealed container until a pre-determined pressure is achieved within the sealed container. A plant matter sample is digested with the rumen fluid so treated. The digested sample is the measured for absorbance or reflectance using a spectrophotometer. The digestion values and the absorbance or reflectance values are then correlated to construct a standard curve for predicting fiber digestion values using spectrophotometric analysis, preferably NIRS analysis.
