Jacks, Jennets, and Mules 365 



Usually this cross is harder to obtain than the cross 

 producing the mule, as the stallion usually refuses to 

 breed jennets. This necessitates that the larger number 

 be produced by artificial impregnation, or by a stallion 

 that has been raised in company with the jennets, and 

 not allowed to serve mares. Because jennets are smaller 

 than mares, it has been argued by many that the cost 

 of keep is correspondingly less and therefore the hinney 

 is a more profitable market animal than the mule, as the 

 feed for the jennet costs less than for the mare. One difii- 

 culty with the enterprise is that good jennets are not 

 used for the production of hinnies but for the production 

 of jacks, and therefore the smaller and pony-like jennets 

 are the ones used for hinney production. This results 

 in a small type of animals of low marketable value. 

 The other difficulty is in the management, on accoimt 

 of the use of artificial impregnation or the care 

 which must be taken with the stallion. It is probable 

 that hinney production will be increased to some extent 

 in the future, but it is extremely doubtful whether it 

 will ever become large enough to produce any noticeable 

 effect on the market situation.
