Flaxseed is used ‘only to a limited extent for feeding purposes, 
viz., mostly as a calf feed, its high price being rather prohibitive 
for feeding to other farm animals. It is always ground for calf 
feeding and mixed with boiling hot water in the proportion of a 
pound of meal to a gallon of water. The jelly-like liquid thus 
formed has a laxative effect and forms a highly-prized component 
of calf rations. It is generally fed mixed with standard, easily- 
digested concentrates, as wheat middlings, ground oats, barley, ete. 
(p. 221). Flaxseed contains about 22 per cent protein, 33 per cent 
fat (oil), and 7 per cent fiber ; it has a high digestibility, containing 
over 20 per cent digestible protein, 17 per cent nitrogen-free extract, 
and 29 per cent fat; owing to the large content of digestible fat, its 
nutritive ratio is considerably wider than linseed meal, viz., 1: 4.0 
(p. 363). 
Cotton Seed.—Only relatively small amounts of cotton seed are 
now fed to stock on account of the value of the seed for the manu- 
facture of cotton-seed oil. Formerly the seed was used quite 
generally throughout the South as a feed for farm animals. It is 
fed either raw, roasted, steamed, or boiled. The composition of 
the cotton seed is, on the average, as follows:

It contains about 11 per cent of digestible protein, 83 per cent 
digestible carbohydrates, and 18 per cent digestible fat. Cotton 
seed possesses a high feeding value, especially as a cattle feed, but 
has sometimes proved injurious to stock on account; of the lint and 
the dust that it collects. The main reason for its present limited 
use as a stock feed is, however, that the seed can generally be sold
