72 DUAL PURPOSE CATTLE 



petent authority to be "the finest lot of cattle of these breeds ever 

 seen together." The report also said "the feed of each cow was 

 weighed out daily and charged at prices fixed by the Exposition au- 

 thorities" considerably higher than the average farm value. 



The milk of each cow was weighed at each milking, three times 

 a day, and credited to her. A composite sample of the milk was taken, 

 and the per cent of fat ascertained every Wednesday by the Babcock. 

 By this percentage, combined with the average of the lactometer 

 reading, the total solids were determined. 



A churning of the milk from each herd was made one day each 

 week, and the week's yield of churned butter determined therefrom. 

 Butter was credited at 25 cents per pound on a basis of 85 per cent 

 butter fat. Total solids at 9 cents per pound. 



The "Dairyman" statement of results makes no note of the date 

 of calving other than by a footnote on five cows: No. 26 "did not 

 calve for two weeks after test began;" No. 29 "did not calve till May 

 7th;" No. 31 and 45 "arrived 18 days late;" No. 48, "last calf, Octo- 

 ber, 1900." No. 40, Tryste, was that cow of the Red Polled lot which 

 had given birth to her calf on February 18th, 1901, 70 days before 

 the test began. Moreover, she was born on April 15th, 1888, at Whit- 

 lingham, near Norwich, and was transferred to America in the au- 

 tumn of 1892, so that she did credit to her breed. It is well to note, 

 when considering the gain in weight of most of the cows, the con- 

 clusion from tests made at the Minnesota Experimental Station from 

 January 1st, 1893, as stated by Principal T. L. Haecker in Bulletin 

 No. 67, dated April, 1900, that "it requires as much dry matter to 

 produce a pound of gain in a cow while giving milk as it does to pro- 

 duce a pound of butter fat. . . . The chief factors that deter- 

 mine the adaptability of a cow for dairy work appear to be her feed- 

 ing capacity, the proportion of her food needed for body mainten- 

 ance, and the disposition made of the nutrients available for product."
