The average daily cost of food per day was 12 . 1 cents 

 per cow with the farm-grown ration and 19.3^ with the 

 oil mill ration. 



While it cost much more to feed the cows on the pur- 

 chased ration, we may not pronounce this the least 

 economical ration until we have noted the amount of 

 butter produced by each. 



3Iilk and butter produced by feeding a ration consisting' 



largely of cotton seed and sorghum hay vs. one 



containing cotton seed meal and hulls. 



The product obtained was greater with the oil mill 

 ration, the increase in milk being 43 per cent and in but- 

 ter 34 per cent. This increased production of milk and 

 butter with the purchased ration is due largely, if not 

 entirely, to the larger quantities of food consumed. 



If we take 20 cents per pound as the value of the but- 

 ter and assume that the manure and skim milk have suffi- 

 cient value to pay for the labor of caring for the cows 

 and making the butter, we have the following statement 

 of the cost and profit on butter.
