CREDIT FOR CALVES. 



The large credit of 95 calves for each 100 cows in the herds during 

 the first year was greater than one would ordinarily expect. It was 

 due to a considerable number of cows being sold out of the herds a 

 few months after freshening. 



During the second year calves brought lower prices, thus reducing 

 the income from that source.

CREDIT FOR MANURE. 



Three factors were considered in determining the credit for manure : 

 '(1) The proportion of fertilizing constituents in the feed which was 

 returned in the manure, as taken from standard tables; (2) the per 

 cent of manure voided in the barn; and (3) the per cent of the fer- 

 tilizing constituents saved in storing and handling.
