434 TlIlRTIKTII AXNI'AL REPORT 



Another experiment was planned and conducted along the same 

 line so as to be a check on the first experiment. Some few changes 

 were made in that cottonseed meal was substituted for cottonseed 

 cake and the amounts of all feeds were increased. In addition to 

 the regular ration of alfalfa hay, silage and cottonseed meal, rolled 

 barley was given to those cows producing more milk than was 

 provided for in the regular ration. 



RATIONS 



All of the rations were figured so that each lot received the 

 same nutrients according to the amount of milk ])roduced. 



The rations used were as follows : 



Ration 1. Alfalfa hay, 22 lbs. Silage, 45 lbs. 



Ration 2. Alfalfa hay, 30 lbs. Cottonseed meal, 4 lbs. 



Ration 3. Alfalfa hay, 15 lbs. Cottonseed meal, 4 lbs., and 

 silage, 45 lbs. 



In addition to the above rations, the Holstein cows were fed 

 one pound of rolled barley for each three pounds of milk produced 

 over 30 pounds daily, while the Jerseys were fed one pound of rolled 

 barley to each three pounds of milk over 25 pounds. 



cows 

 Nine cows were used in the test. All of these cows were giv- 

 ing a fairly good flow of milk and none of them was about to go 

 dry. They were divided into three lots of three cows each. The 

 lots were balanced as well as possible in regard to breed, period of 

 lactation, and quantity of milk given. To overcome any differences 

 in the above points and in individuality, the lots were changed to 

 different rations each month. In interpreting results, the rations 

 and production have been calculated for three periods collectively 

 and no attempt has been made to draw conclusions for any one 

 period. 



The cows were divided into lots as follows :
