The Relation of Food to Milk-Fat. 8Y 



A comparison of the records of all the cows in table lY shows that 

 with one exception (Gem Valentine) there are no greater variations 

 among the cows which alternated from the nsnal ration to palm nut 

 meal than among those which were fed an unchanging ration. Thus, 

 taking everything into consideration, we do not feel warranted in 

 saying that the feeding of palm nut meal increased the per cent of 

 fat in the milk. 



Conclusions. 



For two terms of twenty-two weeks, nine cows were fed in lots 

 of three each on different i-ations, the nutritive ratios of which were 

 about 1:4, 1:6 and 1:9 respectively. During this time the percent- 

 age of fat in the milk of each lot increased slightly and gradually 

 without regard to the kind of ration. 



For continuous feeding, the medium ration appeared to give 

 better results as to yield of milk than either the narrow or wide 

 rations. 



"When tlie food of the cows was changed from the usual ration to 

 one containing from four to seven pounds of palm nut meal and 

 then to the usual ration again, there were variations in the fat con- 

 tent of the milk, but no more nor greater than when the food of the 

 cows was unchanged.
