TREATMENT OF MANGE AND SCABIES 129 



Plants for dipping cattle range from the simple to the elaborate after 

 various plans. Directions and estimates for the construction of such 

 plants, together with much other valuable detail as to dipping, may be 

 obtained from the Bureau of Animal Industry, United States Depart- 

 ment of Agriculture, upon application for bulletins relating to the sub- 

 ject (Bull. No. 152). 



The temperature of the dip when used should be from 102° to 108° F. 

 Each animal should be kept in it two minutes and be completely sub- 

 merged before coming out. The treatment is to be repeated in twelve 

 to fourteen days. 



After dipping the precautions against reinfection, already referred to 

 in connection with sheep scab, are to be observed. 



Treatment of Psoroptic Scabies of the Horse. — The treatment of 

 this scabies of the horse does not differ materially from that given for 

 mange in the same animal. From the fact that the mites do not burrow 

 and thus obtain a degree of protection from the acaricide, it is easier to 

 control than the latter form. 



The preliminary application of soap and water, as directed in the 

 treatment of mange, should be followed here, after which the same 

 general acaricide treatment may be employed. The lime and sulphur 

 preparation is probably of more use for this form of scab in the horse 

 than for the sarcoptic. It is prepared according to the formulae given 

 for scab in sheep (page 125), either formula No. 1 or formula No. 2 being 

 used, according to the age and extent of the lesions. It can be applied 

 as a spray or with a brush, being at the same time well worked into 

 the scabs. The treatment should be repeated at intervals of eight to 

 ten days until all indications of the presence of the mites have disap- 

 peared. 



The precautions against reinfection, involving disinfection of harness, 

 clothing, stalls, etc., as given under equine mange, are to be observed. 



Treatment of Chorioptic Scabies 



Treatment of Chorioptic Scabies of the Horse. — Clip the hair from 

 over the affected parts, usually from the hocks down. It is well in any 

 case to treat the fore legs in the same manner as these may have been 

 infected. A portion of the scales and crusts may be removed with a 

 brush, after which the parts are to be rubbed with a lather of soft or 

 green soap. Let this remain for an hour, then rinse with tepid water, 

 scrape, and allow to dry. 



The acaricides mentioned for the treatment of other forms of scabies 

 in the horse will apply here as well. The fact that the affected area in 

 chorioptic scabies is usually limited to the lower parts of the legs per- 

 mits of the use of remedies which would not be safe for application over
