THE HOLSTEIN-FRIESIAN

white, as previously referred to, occurs in Dutch herds, and from 

 time to time calves of this color marking are dropped in herds 

 of black-and-white cattle in America, this being probably a form 

 of reversion. The subject of color markings has also received 

 formal action by the Holstein-Friesian Association of America," 

 the executive committee in May, 1910, adopting the following 

 report, which thereby became a rule of the association relative to 

 colors barring animals from registration, "(i) Solid black. (2) 

 Solid white. (3) Black switch. (4) Solid black with white on 

 belly only. (5) Black 

 on legs, beginning at 

 feet and extending to 

 knees and hocks. (6) 

 Black on legs, begin- 

 ning at feet and ex- 

 tending to knees, with 

 white interspersed. 

 (7) Gray, or mixed 

 black and white pre- 

 vailing. (8) Patches 

 of other colors than 

 black and white 

 red, brown, dun, etc. 

 (9) Red and white." 



The size of the 

 Holstein-Friesian puts 



it among the largest breeds of cattle. At birth calves usually weigh 

 from 90 to 100 pounds, sometimes reaching the extreme weight of 

 125 pounds. The Advanced Registry standard of the breed speci- 

 fies weights of at least 1 800 pounds for the bulls and 1000 pounds 

 for the cows, at maturity. B. W. Potter, following an investiga- 

 tion of weights of 60 large record cows tested between 1894 and 

 1906, reports on only 13 weighing more than 1500 pounds each 

 and only 27 surpassing the i4OO-pound mark. Only 9 weighed 

 less than 1200 pounds, and the average weight of the 60 was 

 1383 pounds. Of the 25 bulls not one weighed less than 1800 

 pounds and only 5 less than 2000 pounds, while only 3 weighed 

 over 2400 pounds. The average weight of the bulls was 2164
