Cholesterine. — Cholesterine is a substauce somewhat resembling 

 fat of au uncertain nutrient value. 



Dextrin. — Dextrin is an intermediate product between starch and 

 sugar. 



Digestive Co-ekficient. — A digestive co-eflicient is a figure indi- 

 cating the percentage of a food ingredient which can be 

 digested and assimilated by au animal — the same having 

 been deduced from actual ex[)eriineut. 



Dry Matter. — Dry matter signifies a material free from water. 



Ether Extract. —Ether extract is that portion of the plant soluble 

 in ether. It comprises the group of fatty substances, occur- 

 ring in the largest amounts in seeds and b^'-products, such as 

 gluten, corn germ, cotton seed, and bean meals. 



Among these ether soluble bodies may be mentioned neu- 

 tral fats, free fatty acids, vegetable wax, resins, cholesterine, 

 lecithin, and coloring matters such as chlorophyll, etc. 



As a nutrient, ether extract produces heat and energy for 

 bodily warmth and force to run the mechanism, serves to 

 prevent undue waste of albuminoid*, and when in excess is 

 transformed into animal fat. 



Fat, Crude. — Same as ether extract. 



Feeding Standards. — Feeding standards are definite combinations 

 of the several groups of nutrients (protein, fat, aud carbo- 

 hydrates) to be fed daily to farm animals in order to attain 

 specific ends. These standards are deduced from the results 

 of a large number of carefully conducted feeding experiments. 



Fibre, Crude. — By crude fibre or crude cellulose is meant the 

 woody structure or frame work of plants. As a nutrient it 

 produces heat and energy, acts as au economizer of protein, 

 and when in excess of bodily needs is transformed into fatty 

 tissues. 



Fodder Ration. — A fodder ration is a distinct amount by weight of 



coarse fodders and concentrated feeds, so proportioned as to 



secure a definite feeding standard. 

 Glyceride. — Glyceride is but another term for ordinary fats. 



Chemically speaking a fat is a combination of fatty acids 



with glycerine. 

 Gums. — Gums are classified wnth the carbohydrates and so far as 



digestible have an equal food value. 

 Hydrocarbons. — Hydrocarbons are bodies composed of carbon and 



hydrogen, but rarely present to any extent in ordinary feed 



stuffs. 

 Hydrogen. — Hydrogen in its natural state is the lightest of all gases ; 



when combined with carbon, oxygen and sometimes with 



nitrogen, sulphur and phosphorus it forms all kinds of 



organic substances.
