THE WIBBERLEY FEEDING STANDARD 235 



Total . . 3-26 15-14 



In the case of a cow yielding, say, 4 gallons of milk 

 per day, it would not, as may be supposed, be suffi- 

 cient to increase the quantities of each of the foods 

 contained in Ration 2, in order to supply additional 

 nourishment. So doing, would make the ration too 

 bulky. 



In practice, 2 st. or 28 lbs. of dry fodder is about 

 as much as a cow can consume, especially when 6 st. 

 of green fodder is also being fed. It may also be men- 

 tioned that fed on green fodder alone, a cow will con- 

 sume up to 9 or 10 st. per day. 



We may look upon No. 2 as a basal ration, and for a 

 cow yielding over 3 gallons of milk per day (or even 

 2J gallons if the cow is in poor condition) we may 

 obtain the higher starch equivalent required, and the 

 extra digestible protein, by feeding concentrated food. 



A useful rule to follow would be to allow about 

 2 lbs. of concentrates for every \ gallon of milk over 

 the 3 gallons standard, or over 2\ gallons, if the cow 

 is in poor condition. 



According to the table a 4 gallon cow would require 

 a daily ration equivalent to 18 lbs. of starch and con- 

 taining 4 lbs. of digestible protein. 



The question arises, what concentrates should be 

 used to bring the basal, or No. 2, ration up to this 

 standard?
