NA VE — NA VICULAR DISEASE 



Nave. — The nave of a wheel is the wooden centre 

 from which the spokes radiate towards the felloe. (See 



Felloe^ 



Navel 111. — This is an unfortunately by no means 

 uncommon, though it is a most fatal disease amongst foals. 

 The cause of an attack is believed to be blood poisoning 

 through the entrance of some noxious germs into the wound 

 caused by the rupture of the navel string at the time of 

 birth, but cases are known in which a young animal has 

 been attacked whose navel cord had been healed for some 

 time. It is worthy of attention, too, that the young stock on 

 some land are far more susceptible to attacks of navel ill 

 than those belonging to a stud a few miles away ; a fact 

 which is worthy of the attention of breeders. 



Symptoms. — As a rule the foal is seized during the second 

 or third week of its existence, the first symptoms being 

 dullness, accompanied by fever and lameness. If examined, 

 a soft swelling will be found on one of the joints, possibly 

 on more than one, and this is invariably very tender and 

 there is considerable heat, and a tendency to suppurate. 



Treatment. — If not attended to at once the death of the 

 foal from the effects of blood poisoning is likely to occur 

 within ten days, but in most cases the prospects of a fatal 

 termination are considerable. The affected joints should 

 not be poulticed or fomented, but should be dressed with 

 biniodide of mercury one part, and lard eight parts. The 

 question of medicine must depend upon each individual case, 

 as sometimes the bowels are constipated and sometimes 

 not. (This disease is also known as Arthritis, Joint III.) 



Navicular Bone is situated on the back of the hoof 

 below the short pastern bone and above the pedal bone.
