content of the coarse fodder was left out of account, as this was constant 

 in all the periods. It was 0.5 kg. in the preparatory period. In sub- 

 sequent periods palm-nut cake and two kinds of cocoanut cake were 

 substituted for a portion of the grain ration, so as to maintain the 

 protein content exactly the same as in the preparatory period, and to 

 increase the fat content of the ration up to 1.706 kg. per 1,000 kg. live 

 weight. In the second and the last periods disembittered lupine was fed 

 with the basal ration of coarse fodder and wheat bran, giving a ration 

 relatively poor in fat. The changes from one ration to another were 

 made gradually and were not accompanied by any apparent disturbance 

 of tbe cows. 



A summary of the average results with each cow is given in the 

 following table : 



Effect on milk of feedhuj rations rich and poor in fat. 



Cows 655 to 3579 were of the Simmenthaler breed and 1 to 5 of the 

 Altmiirker. 



The authors conclude that a one-sided increase of the fat content of 

 the ration up to 1 kg. of fat per 1,000 kg. live weight had no influence
