SECTION I 
Plants Dangerous When Included in Hay and 
Coarse Feeds. 
Certain animals are poisoned by hay, straw, ensilage, 
etc., when they could have pastured with impunity on 
the fields where the feed was raised. There are several 
reasons why this is so. In the first place, animals in pas- 
ture have a better chance to pick their food. The plants 
grow up separately and distinct from each other, and 
there is usually enough wholesome feed to allow of a 
choice. It thus often happens that a weed, refused 
by an animal in pasture, may be eaten when cured 
and mixed with the hay. This is especially so where the 
amount or concentration of the ration is insufficient. 
Again, certain weeds which are eaten with impunity in 
pasture may cause trouble when eaten by an animal con- 
fined to a non-succulent ration. The laxative nature of 
the green grass and the freedom of exercise give the ani- 
mal in pasture or on the range a much better chance to 
overcome the effects of toxic substances. It may also be 
pointed out that moulds and bacteria grow on forage 
under conditions that would rarely if ever obtain in the 
field.
