440 MANAGEMENT AND FEEDING OF SHEEP 



emerge from the vat, it may be necessary to give them 

 some assistance when walking up the incline and to 

 squeeze some of the ooze out of the wool before they 

 reach the draining pens. When dipped in a tub, two men 

 are called for to lift them. One grasps the forelegs after 

 the sheep has been laid on its side and the other the 

 hind legs, and it is lifted into the tub with the back 

 downwards. 



Care of sheep subsequently to dipping — As soon as 

 sheep have been dipped, the aim should be to at once 

 change their quarters. In fact, it is imperative that this 

 shall be done, at least for a time, in the case of sheep scab ; 

 otherwise, re-infestation will take place. This may usually 

 be accomplished without difficulty after the season for 

 pasturing has arrived. But when the dipping must be 

 done in the winter season, change of quarters may not be 

 practicable. In such instances there is no way of escape 

 from the necessity for disinfecting the quarters occupied 

 by the sheep. The necessity for disinfecting would not 

 seem to be always imperative. When the quarters pre- 

 viously occupied by sheep have been completely vacated 

 for, say, six months, in the case of scab, disinfection 

 would not seem to be necessary. The labor and cost of 

 disinfection should not be imposed when the necessity 

 for it does not exist. 



When disinfection does take place, it should follow 

 the second dipping; that is, when the two dippings follow 

 each other in from lo to 14 days, as they should for scab. 

 The disinfection should be very thorough. It should be- 

 gin by removing all litter and manure from the quarters 

 previously occupied by the sheep, including the yards. 

 Thorough spraying of the sheds inside and out, of the 

 racks, mangers and alleys, and of the yards and fences 

 inclosing them should follow. Various ingredients may 

 be used in thus disinfecting the premises. A coal tar dip 

 will be very eflfective. A 5 per cent carbolic acid solu- 

 tion is also excellent. But whv not use the residue of the
