234 FARMING ON FACTORY LINES 



It will be noticed that in the table, starting with a 



2 gallons per day cow as standard, an additional \ lb. 

 of digestible protein is allowed and the starch equiva- 

 lent of the ration is increased by 1\ lbs. daily for every 

 additional j gallon of milk yielded. 



As an example of the use to which the table given 

 may be put, and to demonstrate the comparative prin- 

 ciple previously referred to, on which rations may be 

 compounded, a winter dairy cow, yielding from 2J to 



3 gallons of milk per day, would be considered to be 

 well fed on a daily dietary of 1| stone of meadow 

 hay, 4 stone of swedes, 3 lbs. of decorticated cotton 

 cake, and 3 lbs. of maize meal. We can set out the 

 digestible protein and starch equivalent of this ration 

 in the following manner: — 



1| et. meadow hay 

 4 st. swedes 

 3 lbs. decorticated « 

 3 lbs. maize meal . 



Total . .2-21 15-08 



This ration, according to the table, whilst having a 

 correct starch equivalent, even for a 3 gallon cow, is 

 deficient to the extent of approximately f lb. of digest- 

 ible protein per day for such an animal, whereas the 

 following Continuous Cropping ration has practically 

 the same starch equivalent and contains over 3 lbs. of 

 digestible protein : —
