in her being excessively fat at parturition. Beginning ten 

 days after the birth of the calf, this cow in seven days pro- 

 duced 291 pounds of milk containing 5.1 per cent of fat. Her 

 average for the entire milking period of eleven months was 

 3.2. During the year she was fed a normal ration for a dairy 

 cow, resulting in her being in a moderate condition only at 

 the time of next parturition. Beginning the same interval 

 after calving as before she produced 224 pounds of milk in 

 seven days with an average fat percentage of 3.63. The 

 average for the entire milking period was 3.00 per cent.
