Straws are a residue obtained after harvest of the plants grown for their seeds and their nutritional value
it is a very low roughage. In our country and in the world

It is formed. 1.5 billion tons of straw every year in the world and
it is estimated that similar herbal remnants are obtained
(Açıkgöz 2001). When we say straw in our country,
it is understood that many wheat grasses. our Country

The nutritional values of the forage grasses legume
Although it is lower than straw, it is the most produced straw in agricultural enterprises. Barley straw
More than 90% of organic materials are of structural quality

The mineral content of wheat straw is higher. Feeding value among the forage grasses
One of the lowest is rye straw. Fresh
Rye straw is reported to cause colic.
It is necessary to take care that the rye straw is not contaminated with rye spurs and microorganisms.
Oat straw is better than summer wheat and barley straw.

Use of Hay in Animal Nutrition
Considering the raw nutrient content of straw, it is examined in the class of low quality roughages.
Therefore, they should be used in animal feeding at a limited level. The use of such roughages
the main factors limiting are high levels of cellulose and
This is because they contain low amounts of crude protein with lignin and their digestibility is low.
Low quality roughages, generally only for the feeding of adult ruminants and, to a lesser extent, horses,
It can be used close to the living share or at the living share level. Since these feed ingredients are bulky, feed
It also limits its consumption. In ruminant animals
One of the important factors limiting feed consumption is digestion.
