THE PRINCIPLBS AND PRACTICE OF BREEDING FOR THE TURF AND FOB 



GENERAL PURPOSES. 



Before proceeding to enlarge upon the practical management of the 

 breeding stud, it will be well to ascertain what are the known laws of 

 generation in the higher animals. 



The union of the sexes is, in all the higher animals, necessary foi 

 reproduction ; the male and female each taking their respective share. 



The office of the male is to secrete the semen in tiie testes, and emit it 

 into the uterus of the female, where it comes in contact with the ovun> 

 of the female — which remains sterile without it. 



The female forms the ovum in the ovary, and at regular times, varying 

 in different animals, this descends into the uterus for the purpose of 

 fructification, on receiving the stimulus and addition of the sperm-cell of 

 the semen. 



The semen consists of two portions — the spermatozoa^ which have an 

 automatic power of moving from place to place, by which quality it is 

 believed that the semen is carried to the ovum ; and the sperm-cells, 

 which are intended to co-operate with the germ-cell of the ovum in form-
