MANNER OF CALCULATING A RATION. 



43 



\Ve shall now give a general idea of how a farmer may cal- Manner of calcu- 

 culate a ration. No technical skill is required, only very careful latinfl a ration - 

 handling of the data contained in the tables previously referred to. 



In the present example, we may suppose that a farmer has 

 50 cows of an average weight of 1000 Ibs., and that all condi- 

 tions are favorable for cattle feeding ; also that the winter 

 feeding lasts from November to May, we may say 200 days, 

 and that the barn contains 40,000 Ibs. clover hay and 70,000 

 Ibs. oat straw. Residuum cossettes have been obtained at 

 the beet-sugar factory and siloed, the quantity being 200 tons 

 or 440,000 Ibs. As 70 tons of beets offered to the factory have 

 been refused, they must also be kept cturing the winter, and 

 represent 154,000 Ibs. Under the best circumstances, it is not 

 desirable to consume all the hay on hand, but for the present 

 we may simply suppose that it is all fed, other fodders being 

 put aside for spring feeding. The 40,000 Ibs. clover hay to be 

 consumed in 200 days means 200 Ibs. per diem or 4 Ibs. per 

 oow. In the same manner the consumption of oat straw 

 should be 7 Ibs. per diem, 44 Ibs. cossettes, and 15 Ibs. of beets. 



If we should use only what is on hand, the daily ration for 

 each cow would be as follows:
