28 BREEDING AND REARING OF 



undue weight on one of his limbs, springing is likely 

 to result. 



Now when the short grazing is the cause of the 

 trouble the colt can be put in the stable and fed with 

 suitable food. Green food can be cut and carried to 

 him so he will not have to expose the limbs by grazing. 

 Should the springing be caused by the dam being so 

 low, it may be obviated by the colt being put in a 

 stable and fed on cow's milk, or milk from his dam; 

 some jennets give large quantities of milk. I am 

 aware that this course of treatment would give the 

 owner much trouble and worry. But after the colt 

 is from one to two years old, he is not so liable to 

 spring. When the bony matter predominates over the 

 animal matter the trouble subsides. A fine, well-bred 

 jack colt, that promises to make an extra good animal, 

 will pay his owner to give him some attention when 

 young. From my long experience in handling this 

 stock, I do not know of any animal that is more 

 remunerative than the growth of a fine jack colt. 



From what has been written as regards rearing 

 jacks and jennets, you will perceive how careful we 

 should be in the selection of our stock to commence 

 rearing a herd. In selecting a jennet jack we should 

 bear in mind that as a general rule in breeding 

 stock like begets like ; hence we should select a model 

 jack as near as possible in every respect — form, size, 

 color, constitution and a good general make-up. In 

 judging of the constitution the animal should have a 

 well developed chest, plenty of room for the heart and 

 lungs to play. Bear in mind that they are the principal 

 vital organs in all domestic animals. Length is an 

 essential point in the make-up of a jennet jack. I re-
