Breeding and Some of its Effects. 181 



The symptoms are well marked, every dairyman being 

 more or less familiar with them, probably the first seen 

 is a slight unsteadiness of the gait, crossing of the hind 

 legs and a swaying motion when walking; later on the 

 head droops, no notice is taken of the calf; there is 

 stamping of the feet and whisking of the tail, paralysis 

 conies on; the vow becomes stupid and the eyes dull, 

 and may lie on the breast bone, with the head around to 

 the flank or else flat on the side. The breathing is loud, 

 the urine and feces are retained and rumination (chew- 

 ing of the cud) ceases, the amount of milk given is 

 lessened, and in bad cases bloating may occur. 



The most satisfactory treatment is of the preventive 

 order, by limiting the quantity of concentrated food and 

 by giving a purgative dose of salts just before and im- 

 mediately after calving. Schmidt's treatment is highly 

 lauded; it consists of the injection of a drug (iodide of 

 potash) into the udder by means of a funnel to which is 

 attached rubber tubing and a milk tube. 1 One or two 

 drams of the drug are dissolved in one pint of cold 

 boiled water, one-fourth of the amount being siphoned 

 into each teat, the udder being well hand-rubbed after 

 the injection; a one- ounce dose of aloes is also given if 

 the cow is conscious. The udder injection may be re- 

 peated twice or three times in the day; reports of this 

 treatment seem to indicate that two injections at the 

 most are sufficient for the usual cases. The following 

 treatment has been very successful in the hands of Dr. 

 Hugo Eeed, of Guelph, Canada; it is: 



i Other investigators recommend Chinosol or a half pint of a 5 per cent, 

 solution of lysol as the udder injection.
