AN INCREASE OF PROTEIN AND OF TOTAL NUTRIENTS. 
One hundred and thirty-four records, each of which covers a 
period when there was an increase of total nutrients with that 
of the protein, show, on the average, no shrinkage in the milk 
yield. Without change of ration, there is usually expected, dur- 
ing a similar period, at this stage of lactation, a diminution of 
about 2.5 per cent. The very slow rate of gain in live weight 
was moderately increased.
