THE OIL BY-PRODUCTS 209 



Its laxative effect and high protein content make it valuable 

 for this class of animals. 



For Milch Cows. — Up to three pounds per day, linseed 

 meal will improve almost any dairy ration. An excess of 

 linseed meal may affect the quality of the butter, as it tends 

 to produce a soft butter. 



For Work Horses. — One-half to one pound may be fed to 

 advantage to horses. McCampbell at the Kansas Experi- 

 ment Station ^ found that one pound of linseed meal was 

 equivalent to four pounds of bran when fed with com, oats, 

 and prairie hay. It is not necessary, however, when they 

 are on pasture. This feed gives the horse a gloss and sleek- 

 ness of coat which materially improves the appearance. 

 It is very good to restore overworked or overfed horses to 

 good condition. Some horses cannot use it, as it scours them 

 too much. 



Flax feed or screenings consist of a variable mixture of 

 inferior flaxseed, weed seeds, stalks, leaves, dirt, etc. Like 

 all screenings, it should be finely ground to destroy the vi- 

 ability of the weed seeds present. It is not recommended 

 at the prices usually asked for it. It is often used as a con- 

 stituent of mixed commercial feeds, and is sometimes sold 

 under fancy trade names, as " flax flakes," " linomeal," etc. 



Flax plant by-product consists of flax pods, inferior flax 

 seeds, and portions of the stem. It is usually used in mixed 

 commercial feeds, although it is sometimes sold as " flax 

 bran." Its feeding value is quite low. 



Unscreened flax oil feed is the by-product resulting 

 from the extraction of the oil from unscreened flaxseed. It 

 is lower in feeding value than oil meal from the screened seed.
