A DUTCH HERD OF BELTED CATTLE 



The remarkable uniformity of the white pattern in this breed of cattle is a striking illustra- 

 tion of the laws of heredity. To retain perfection in the pattern it is necessary to keep the 

 cattle purebred, as the introduction of new blood, even from a pure strain of the same variety, 

 may upset the coat color. The breeding of these cattle in Holland has been declining except for 

 ornamental purposes, as it is found that in breeding solely to obtain the pattern, the other de 

 sired qualities of the animals were impaired. (Fig. 1.) 



RESULTS OF CROSSING BELTED AND PEED CATTLE 



This diagram illustrates the matings of the Lakenvelder (Dutch Belted) bull, Albert Wassen- 

 aar, with five piebald cows of the breed called Holstein-Friesian in America. P, illustrates both 

 sides of the bull, P2 both sides of each of the five cows, and Fi the five calves. The fourth cow 

 was red, the others black. Note the production of solid black calves by two of the cows. The sire 

 was shown to transmit self color in matings with cows of his own breed (See Fig. 4). Note the 

 transmission, by the fifth cow, of the white face similar to that of a Hereford. (Fig. 2.)
