protein and starch required according to standard for the production of 

 the niilk obtained. The average amount of digestible protein fed was 

 1. 98 lbs. per day, that required 2.04 lbs. ; the average starch equivalent 

 of the food fed was 12.83 lbs., that required 11.64 ^bs. 



As in previous 3'ears the home grown foods were valued according 

 to the following arbitrary scale. 



Haj- £. 15s per ton. Swedes los od per ton. 



Oat Straw £1 los " Mangels ids 6d " 



Barley Straw £1 3s " Turnips 8s od " 



Grass 3.S 6d per week for sprinsr calvers. 



These prices are probably on the whole, rather higher than the bare 

 cost of production and represent what may be termed the feeding or 

 consuming value. The purchased foods were taken at full cost without 

 any deduction for the value of the manurial residties arising from the 

 consumption. 



The estimated average cost of feeding per cow per annttm was as follows.

There were considerable variations from the mean, the maximum cost 

 of food per head being £ 20 los and the minimum £ 13. The hay and grass 

 represent on the average one-half, the arable crops one-fifth and the 

 purchased foods one-third of the total cost, results in close agreement with 

 those found in previous years. 



Of the total number of cows 42 did not yield milk equivalent in value 

 to the estimated cost of feeding when the milk was valued at 6d per gal- 

 lon, 24 per cent when the value was yd per gallon, 15 per cent when 8d per 

 gallon, 10 per cent when qd per gallon and 7 per cent when Lod per gallon. 



Assuming that 100 gallons of whole milk give roughly 90 gallons of 

 skim milk and valuing the latter at 2d per gallon, then deducting the value
