The gains of both calves were irregular from week to week, due per- 

 haps more to variation in the contents of the bowels than to differences 

 in the weight of carcass itself. In the following table the gains, aver- 

 age dry matter per pound of gain, and the average amounts of feed 

 required to produce 100 pounds of gain are given for the two calves for 

 periods of five weeks. 



Table IX. — Showing food required for 100 pounds of gain. 



BROWN SWISS. HOLSTEIN. 



These calves were able to make gains on a very low consumption of 

 dry matter. The Holstein, having fresh milk unskimmed after the 23d 

 of June, continued to put on flesh at a food expenditure of not quite 

 two pounds of dry matter per pound of gain, certainly a very creditable 

 performance. 



In the following table a comparison is made between the average 

 amount of grain and milk required by the Duroc Jersey and Poland 

 China pigs in the three periods reported in Table III for 100 pounds of 

 gain and the average amount of milk, hay and grain required for 100 

 pounds of gain by the Brown Swiss and Holstein calves. 



Table X.—Pigs and calves compared. 



The pigs and calves in these experiments were subjected to the same 

 conditions of weather and treatment. Their grain ration was different. 

 The pigs demanded a very much larger proportion of grain to milk than 

 the calves. 



Keeping these facts in mind the conclusion that the calves put on 

 their gains at an appreciably less expenditure of dry matter will not be 

 misinterpreted. The Holstein required more dry matter when consuming 

 whole milk than skim milk, simply because he was older at the time 

 he received it. While both calves were healthy and thrifty the fact that 

 the Holstein made more economical gains than the Brown Swiss is 

 worthv of note.
