" From the work so far accomplished it appears : 



"(1) That for the production of milk a ration composed of Lespedeza 

 [Japan clover] hay and cotton seed is the most economical. 



" (2) That cotton seed is more economical than cotton-seed meal as a 

 grain ration. 



" (3) That Lespedeza [Japan clover] hay is more economical than Ber- 

 muda hay. 



" (4) That corn meal is too expensive for use in this State. 



"(5) That the ration which will produce milk at the least cost is also 

 the most economical ration for butter, if no consideration be given to 

 the quality of the latter." 



Effect of time of milking and number of hours between 



MILKINGS ON THE BUTTER CONTENT OF MILK, E. R. LLOYD, M. S. — 



"A very constant difference was observed in the butter content of the 

 milk from the morning and evening milkings. * • * In a further 

 study of this matter two cows were used during August and September, 

 1890, in making a series of special tests of the effect of time of day of 

 milkings and number of hours between milkings. During the first week 

 they were milked at 7 a. m. and at 6 p. m., during the second week at 

 6 a. m. and 7 p. m., and during the third week at 6 a. m. and 6 p. m. 

 • * * Although the results show considerable irregularity, they seem 

 to indicate that day and night influence the amount of butter fat much 

 more than does the number of hours between milkings."
