DAIRY HERD M.—TESTS 44 AND 46. 
The tests on this herd were made during February and 
March, with the usual interval between the tests. "There were 
eight cows in each of the tests, six being pure Jerseys and two 
grade Jerseys. The average estimated weight of the animals 
was 725 pounds, the average age was 8 years, and, at the 
beginning of the first test, the average time since producing 
the last calf was about 2% months. The ration fed in the 
first test was as heavy, and as large in protein as is commonly 
recommended for cows of this weight. The protein was pur- 
posely increased by a large amount (one pound per day) in the 
second test, and the nutritive ratio was thus made quite nar- 
row. Both rations seem to have been well eaten by the cows,
