Total and Average Daily Yield of Milk {I'ounds), 



First period: lx)th herds, standard grain ration. 



In the first period Herd II. produced o.l per cent, more milk 

 tlijin Herd I., and in the second period 1 per cent. more. It 

 Avould appear, therefore, that the amount of protein fed in the 

 fir.st i)eriod was ample, and that the increase given to Herd 

 II. in the second period was not needed and did not increase 

 the milk flow. In the first period Herd I. gained (5 ])ounds in 

 live weight, and Herd II., 83 pound.s. In the second i:)eriod 

 Herd I. lost 87 pounds, and Herd. II., 73 pounds. 



Average ComposHion of the Herd Milk {Per Cent.). 



First period: botli herds, standard grain ration. 



The analyses for the first period represent the average of 3 

 separate samples, each covering a period of five days ; those for 

 the second i)eriod represent the average of 5 separate samples, 

 each covering a period of five days. Each five-day composite 

 represented the average composition of the herd milk for one 

 week. The sejiarate analysis of each cow's milk was not made.
