Horse-Breeding Methods 77 



It would also tend to increase his average 

 age as a sire. 



We will come to these things later when we 

 consider the ages at which horses with and 

 horses without race records appear in the 

 pedigrees of 2 : 10 trotters, and also when we 

 consider the number of performers sired 

 by two brothers, one of which went to the 

 race track and the other of which did not. 

 Consider two horses, one of which retired 

 from the race track at the age of seven and 

 thereafter spent his life in a box stall, and 

 another horse which was not raced but was 

 driven regularly all his life. At what ages 

 will the two horses be in their best dynamic 

 condition? This will also come up in the 

 pedigrees of 2 : 10 trotters when we consider 

 the ages at which these two kinds of horses 

 get their best progeny. The best progeny are 

 those which "breed on," and those which 

 breed on are not always the star performers. 

 Good performance on short distances comes 

 from energy of high potential even when that 

 high potential does not mean a large quantity.
