NUTRITION OF FARM ANIMALS 



Grouping the results regarding the fat content of the milk 

 according to the total amount of milk yielded, it appears that 

 an increase in the percentage of fat in the milk was in general 

 associated with a decrease in the total yield and vice versa. 



TABLE 146. EFFECT OF INCREASING FAT OF RATIONS 



Striking individual differences in cows, however, were ob- 

 served. For example, in two of the experiments the range of 

 increase or decrease for the individual animals consequent on 

 the substitution of fat for carbohydrates was as follows : 



TABLE 147. INFLUENCE OF INDIVIDUALITY ON EFFECTS OF FAT INCREASE 



It seems clear from the foregoing results that under the 

 average conditions of practice no material advantage can be 

 expected from increasing the digestible fat of dairy rations
