278 Agricultural Experiment Station, Ithaca, N. Y. 



In table V it is seen there is no very marked change in the per- 

 centage of fat and yield of milk in the period when the cows were 

 on a full feed of tallow. While there are slight variations in the 

 percentage of fat, they rarely reach one-half of one per cent, and 

 what is of more significance they are not uniform. Some of the 

 cows gave richer milk and some poorer on a full feed of tallow than 

 they did before or after. 



It is of interest to note the average daily yield of milk and the 

 percentage of fat for each cow two months after the close of the 

 experiment which is included in Table Y. It will be seen that all 

 the cows except Pet were still giving practically the same amount 

 of milk of the same quality, and Pet at this time had practically 

 reached the end of her period of lactation. 



CONCLUSIOK 



In this quite extended trial there has been no increase in the fat 

 in the milk by feeding tallow to the cows in addition to a liberal 

 grain ration. These results were obtained with ten different cows, 

 of two breeds of various ages, in various periods of lactation, extend- 

 ing over a period of ten weeks, for at least six of which they ate 

 two pounds per head, per day of tallow.
