Sheep Scab : Its Cuke and Prevention. [Aug., 



(lipping is properly carried out; otherwise Scab can never be 

 eradicated. 



When dipping to comply with Orders of the Ministry of Agri- 

 culture or Kegulations of the Local Authority, it is of the utmost 

 importance to remember that : — 



(1) the dip used must be oue that has been approved by the Ministry of 

 Agriculture. There are a large number of effective dips for scab, 

 non-poisonous as vjell as poisonous, which have been so approved and 

 the responsibility in selecting an approved dip rests with sheep-ovmers, 



(2) the dipping bath must be mixed in the proportions specified as 

 approved by the Ministry. It is inadvisable to make up a dipping 

 bath by mixing two or more dips together, as this may result in 

 neutralising the etfect of both dips for scab, and may in some cases 

 be injurious to the sheep, 



(3) the directions and precautions indicated by the manufacturer on the 

 label must be strictly observed, 



(4) the sheep must be kept immei sed in the bath for the period mentioned 

 on the label. Special attention should he paid to the heads, necks 

 and tails, 



(5) during the dipping operations proportionate quantities of dip and 

 water niust be added to keep the bath up to proper strength, 



(6) after each lot of sheep have been dipped and before the bath is re- 

 mixed the dipping bath should be carefully cleaned out, the residue 

 being disposed of in such a manner that it cannot injure animals or 

 pollute streams. A satisfactory method is to run the residue from 

 the bath into a trench or pit, the sides and bottom of which have 

 been plentifully sprinkled with lime, so that the liquid from the bath 

 runs through the lime before passing into the soil. This is sjjecially 

 important when poisonous dijys are used in order to avoid risk of 

 ijijary to sheep through accumulation of poisonous matter. Under no 

 circumstances, however, should the lime be added to the liquid while 

 it is still in the bath. 



(7) If Arsenical Dips are used, the second dipping should be at half the 

 strength of the first dipping, when two dippings are required, with an 

 interval of not more than 14 days between them. 



Persons using poisonous dips must take the precautions neces- 

 sary for the avoidance of accidents or injury to sheep through 

 the use of such dips, and the Ministry will not entertain any 

 claim for compensation for injury or loss due to their use. The 

 choice of an approved dip rests entirely with the user. The 

 responsibility for the class of ingredients is a matter for the 

 manufacturer of the dip. The approval of the Ministry only 

 means that the ingredients of a dip are effective for Scab in the 

 proportions approved. 



WARNING. — All persons having or having had under their charge a sheep 



affected with, or suspected of. Sheep- Scab, are required by Law to gi\'e notice 



to the Police with all practicable speed. Persons failing to do so are liable to 



heavy fines, and in certain circumstances to imprisonment.
