Feed
evaluation methods aim to give information on the feeds to meet the nutritional
needs of the animal. Therefore feed evaluation is needed to assess the nutritional
value between feeds. The methods to express the feed value incline to measure
mainly digestibility of the feedstuff. Many feed evaluation methods have been
developed and modified over the years to predict the nutritional component of
the feed. The nutritive value of ruminant feeds is assessed by the chemical
composition, concentration and rate and extent of digestion of feed in the
rumen. Chemical, digestibility and enzymatic methods are the main methods that
have been used for feed evaluation. The
Weende and detergent analysis systems are the commonly used chemical methods of
feed evaluation. For many years, feed digestibility has been measured by
in-vivo, in situ and in-vitro digestibility techniques. This paper aims to
review the feed evaluation methods of chemical, digestibility and enzymatic
with emphasis on performance/outcomes, economic consideration and environmental
effects/ footprints.
