QUANTITY AND QUALITY. 



In addition to furnishing the re- 

 quisite amount of nutrients, the 

 food must have a certain bulk. The 

 required bulk is secured by feeding 

 a certain amount of coarse fodder, 

 which aids digestion and helps to 

 kee>p the animal satisfied and healthy. 



The measure of the bulk or total 

 solid matter is the weight of dry mat- 

 ter in the ration. The dry matter is 

 the solid or water-free portion of the 

 food. More latitude is allowable in 

 this than in the case of any single 

 nutrient. 



FEEDING STANDARD VALUE. 



It should be borne in mind that 

 feeding standards are simply a con- 

 cise and approximate statement of 

 the amounts of the different nutrients 

 required by animals, as indicated by 

 the results of experiments and obser- 

 vation. They are not to be regarded 

 as infallible or as absolute formulas 

 which can be followed blindly without 

 regard to the conditions. They are 

 intended toi apply to the average con- 

 ditions. No single standard can be 

 laid down for all conditions. Good 

 judgment and intelligent observation 

 on the part of the feeder are neces- 

 sary in the application of feeding 

 standards as the calculation of ecot- 

 nomical rations is not merely a mat- 

 ter of applied mathematics. The local 

 conditions, as regards the feeding 

 stuffs which can be grown and pur- 

 chased economically, and the value 

 of the products, will have much to 

 do in determining hoiw closely the 



feeder can afford to adhere to the 

 standard. But such standards or for- 

 mulas, used in connection with the 

 feeder's observation of his animals 

 and the markets, are very useful, and 

 have served a good purpose in im- 

 proving the practice of feeding. It 

 is in their abuse that the chief dan- 

 ger lies. 



Ration and Yield. 



In making allowance for the dif- 

 ference in milk yield in different 

 cows, a uniform basal ration may be 

 fed to all the cows, and the amount 

 of the richer grain food varied to 

 suit the demands. Such feeds as 

 roughage and the less concentrated 

 grain foods may be fed uniformly to 

 all the animals. To the allowance 

 of these feeds could be added a 

 quantity of some such feed as gluten 

 meal, linseed oilcake meal or cotton- 

 seed meal, the amount being varied 

 to suit the milk yield of the cow.
