Average amount of milk and hntter produced daily. 



Comparing tlie product obtained when the cows 

 grazed on cowpeas with that made from ordinary pas- 

 turage, we find that the cowpeas gave an average in- 

 crease of 15.8 per cent in milk and 9.5 per cent in butter. 

 It should be noted that this increase occurred in spite of 

 the fact that the cows were further advanced in the 

 period of lactation when grazing on cowpeas than when 

 on ordinary pasture. 



The total amount of product obtained from the three 

 cows during the 19 days while they grazed on cowpeas 

 in a corn field of 3.03 acres was 1129.5 pounds of milk 

 and 59.17 pounds of butter. During this time the three 

 cows consumed a total of 171 pounds of cotton seed 

 meal. 



The three cows Ida, Susan, and Houron, during the 

 19 days while pasturing on coTN^oeas made gains in live 

 weight of 2687 pounds, subsisted for a period of 

 85 pounds for the lot. When the field was grazed so 

 close as to threaten to reduce the milk fiow, these three 

 cows were removed and three dry Jersey cows were sub- 

 stituted. These three drv cows, with a total initial 

 weight of 2687 pounds, substituted for a period of 

 9 days on what remained of the grazing on 3.03 acres, 

 meantime receiving no other food whatever and making 

 gains of 12, 16, and 25 pounds, a total of 53 pounds 

 for the lot. Adding this to the 85 pounds gained by the 

 cows giving milk, we have a total gain in live weight of 

 138 pounds.
