2. Composition of Alfalfa and its Use as a Feed for Farm Animals. 
Preparation. 
Name all the green forage and hay crops in this vicinity. 
Which one of these do you consider the most important ? Why ? 
Presentation. 
Our lesson today is the studj^ of the composition of alfalfa 
and its uses as a feed for farm animals. 
Why do the farmers prize the alfalfa so highly? (One 
of the richest forage crops in America. Contains a high per¬ 
centage of protein. A good quality alfalfa hay contains at 
least 15 per cent of protein, 2 per cent fat, and about 25 per 
cent fiber. It is highly digestible and greatly relished by all 
classes of farm animals.) 
Name some different ways it is used in feeding. (As a 
soiling crop, for hay, silage or for pasture. It is one of our 
most valuable green feeds.) 
What animals especially thrive on it as a green food? 
(Cattle, hogs and sheep.) 
Why is it especially good for dairy cattle and young 
animals? (Its high protein content supplies the protein in 
milk; also acts as a tissue builder for young growing animals. 
Its protein content is too high to feed it only.) 
What feeds will you give with it? (Starchy feeds such 
as corn; they are low in protein.)
