136 INVESTIGATION IN MILK PRODUCTION. 
for when it was increased she regained her weight. The de- 
crease in total nutrients at this stage of the experiment was 
due to the reduction in silage and at attempt to replace it 
it with beet pulp. The change in the amount of nutriment 
was due to the addition of 4 pounds of pulp and resulted in 
an increase in the flow of milk, but there was an abnormal 
depressionin the fat content which raised the nutriment used 
to 7.36 pounds to a pound of butter fat. The increase in 
nutriment the 59th and the 70th week was due to an error 
in feeding 7 pounds of grain instead of 5, the amount as- 
signed to her. Duchess and Leeoma were the only cows in 
the herd that were fed according to yield of milk and butter 
fat, and the result was that both returned butter fat and 
milk solids for the normal amount of nutriment regardless 
of advanced stage of lactation. Duchess returned a pound 
of butter fat to 6.35 pounds of nutriment, while Leeoma re- 
quired .14 less; though this would naturally follow because 
Duchess’ milk contained more solids not fat, and on this ac- 
count she was enabled to return a pound of total solids to 
2.45 of nutriment, while Leeoma used 2.47.
