DAIRY COWS. ^21 



containing 19.758 lbs. butter-fat, showing an average of 3.65 

 per cent fat. Eighty-three H.-F. cows and heifers have made 

 30-day ollicial records exceeding 72 lbs. butter-fat, of which 

 24 made from 72 to 76 lbs.; 27, from 76 to 80 lbs.; 18, from 

 80 to 85 lbs.; 6, from 85 to 90 lbs.; 6, from 90 to 100 lbs.; i, 

 from 100 to no lbs.; and i made over no lbs. of butter-fat. 



A few H.-F. cows have been officially tested for longer periods; 

 and one cow produced in 100 days over 284 lbs. fat, while a 

 heifer under three years of age produced over 227 lbs. in the 

 same length of time. At the World's Fair at St. Louis, where 

 three Missouri H.-F. breeders pitted their individual herd against 

 the pick of the Jersey world, one H.-F. cow produced over 282 

 lbs. fat in 120 days, surpassing the foremost Jersey by over two 

 pounds; and since then a H.-F. cow- has produced officially 

 over 316 lbs. fat in the same time. One H.-F. cow has produced 

 over 453 lbs. fat in 182 1 days, while another produced over 721 

 lbs. fat in one year. This last w^as owned by the Michigan Agl. 

 College. Prof. Oscar Erf, Kansas Agl. College, writes that one of 

 their H.-F. cows has produced nearly 16,000 lbs. of milk in one 

 year, testing from 3.2 to 3.7 per cent fat, and that at the end of the 

 year she was still giving from 25 to 30 lbs. milk per day; while 

 Prof. A. L. Haecker, Nebraska Agl. College, states that a heifer 

 calving at just past three years has given in 39 weeks 15,063.9 

 lbs. milk, containing 492.05 lbs. butter fat, and that she was still 

 giving 45 lbs. milk per day, with 13 weeks before her in which 

 to complete the year's record. A heifer, calving at just past 

 three years of age, in semi-official test under the rules of the 

 Wisconsin Exp. Station, produced in one year, 13,213.6 lbs. 

 milk containing 584.080 lbs. butter-fat. Many H.-F. cows have 

 made very large private records; but it is not the practice of the 

 H.-F. Association to report private records. 



It has been asserted by some persons illy posted as to the facts, 

 that while H.-F. cows did yield large quantities of milk, the milk 

 was below standard in cjuality. Ten gallons of milk per day, by 

 weight 84 lbs., might be considered more than any cow could 

 ever produce; yet under the strictest official test 40 H.-F. cows 

 have yielded in excess of 588 lbs. in a period of seven consecutive 

 days. This herd of 40 cows, of which some were not of full age, 

 produced in a period of seven consecutive days 25,032.2 lbs. 

 milk, containing 821.497 lbs. butter-fat; thus showing an average
