Cattle feeding {Mississippi Sta. Rpt. 1895, pp. 55-59). — These experi- 

 ments are iu continuation of work previously reported in Bulletins 13 

 and 15 of the station (E. S. E., 2, pp. 362, G58; 3, pp. 16G, 875). 



The present experiments, to determine the relative value of different 

 foods (shown in the table) for the production of milk and butter, were 

 made in 1892 with 30 grade cows divided into G lots of 5 each (4 Jerseys 

 and 1 Holstein). The tests lasted 5 weeks. The results are summa- 

 rized as follows : 



Comparisons of different rations for cows. 



The results of these experiments agree very closely with those of 

 former years. From all the exj)eriments the following general conclu- 

 sions are drawn : 



"(1) Equal weights of Bermuda and timothy hay have practically equal values in 

 the production of milk and butter. 



''(2) At the prices at which they can be purchased in Mississippi, Bermuda hay 

 will produce milk and butter at a much less cost than timothy hay. 



"(3) The milk and butter from cows fed on steamed cotton seed costs less than 

 that from cows fed on raw cotton seed, and but little more than one half as much 

 as that from cows fed on cotton -seed meal. 



^ "(4) The butter from steamed seed is superior in quality to that from either raw 

 seed or from cotton-seed meal."' 



Feeding cotton-seed meal to dairy cows, C. F. Ci rtiss {loica Sta. 

 Bui. 32, pp. 437-447). — Using 5 grade Shorthorn cows fresh in milk, the 

 effect was studied of gradually substituting cotton-seed meal for the 

 bran in a grain ration of 12 lbs. of corn-and-cob meal and G lbs. of 

 bran daily. There were G periods of about 2 weeks each. In the first 

 period no cotton-seed meal was fed; in the second period 2 lbs. of cotton- 

 seed meal was substituted for 2 lbs. of bran, and in subsequent periods 

 it was increased 1 lb. at a time until in the sixth period all the bran was 

 replaced by cotton-seed meal. During the first, second, and third 

 periods each cow received daily 12 lbs. of corn fodder and 4 lbs. of hay, 

 and during the fourth, fifth, and sixth 12 lbs. of hay. The last 2 days 

 of each period butter was made from the milk. This was analyzed and 

 scored by several experts at the station and in Chicago. These data 

 are given in full, but no feeding record is given. Neither the volatile
