CARE AND MANAGEMENT OF THE DAIRY HERD. 



81 



Sudden changes in the feed and extremes should be avoided. To keep 

 the bull strong and vigorous he must receive regular exercise. This 

 may be obtained in a small lot, by tread power or in running up and 

 down under a strong overhead line. The tread power is responsible 

 for many a good bull retaining his strength, vigor and ability to breed 

 successfully until an advanced age. It is a common opinion among 

 some that when the bull gets to be three or four years old he should 

 be killed and a yearling take his place. Not so, he has just reached 

 the period of greatest usefulness in his life if he is rightfully handled. 

 Any one with good judgment can see where it would be advisable to 

 secure the services of a tried, mature sire rather than take chances with 

 an untried immature sire. 



In feeding the herd bull it must always be remembered that to main- 

 tain vigor considerable nitrogenous food must be supplied. A grain 

 mixture of oats three parts, wheat bran three parts, corn meal two parts 

 and linseed meal one part, fed along with good leguminous hay and a 

 small amount of corn silage will keep the bull in excellent condition. 

 Some people think that the bull should get his feed from what the cows 

 leave, but this is poor policy as the bull is going to have too much in- 

 fluence over the future of the herd to be treated in this way.

 the age of greatest usefulness. 



Figure 6 shows the pure bred Jersey bull Eminent 19th in breeding 



mdition. This bull has as fine a lot of daughters as can be found 



inywhere and the majority of them are out of grade Jersey cows. The 



iniformity of his get is something remarkable, yet is just what can be 



rpected of a high class, splendid individual with such ancestry back 



)f him.
