TAiiLi: XXVI.— An Increase of Pkotein with J.ittle Change 



OF Nutrients. 



Average at 65 rec- 

 ords from cows 

 averaj^iug 4.5 

 yrs. old aud 5.0 

 mouths in milk. 



AN INCREASE OP 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.
