Abstract

[The objectives of this study are:]
1.To fractionate and characterise rumen degradation kinetics of these fractions in grains (barley, corn, sorghum) and legume seeds (faba beans, peas, lupins).
2.To determine the chemical composition of these fractions by wet chemistry and by Near Infrared Reflectance Spectroscopy (NIRS).
3.To determine the fermentation kinetics and the fermentation end products of these fractions with the cumulative gas production technique.
4.To study the effects of some feed processing methods on fermentation characteristics of these grains. [Results]
At the first stage of this study a new method of feed fractionation was developed to mimic the washing machine procedure. According to this method feeds can be fractionated to a non washable fraction, an insoluble washable fraction and a soluble washable fraction.Using this method, we can study the degradative behaviour of these fractions
