CONKEY'S STOCK BOOK 



Prevention This is another case where the easiest and safest way is to 

 prevent infection. The anti-parasite mixture described above, 

 which can be mixed up at home cheaply, using common barrel salt, will 

 act as a preventive, if kept before the sheep all the time, so that they can 

 help themselves. This mixture is very cheap, costing only 2 l / 2 c. a pound. 

 Ninety pounds of salt and ten pounds of Conkey's Stock Tonic, costing less 

 than $2.50 for the hundred pounds, will be enough to last a flock of 50 sheep 

 for fully four months. 



SCAB This is the 

 scourge of the 

 sheep industry, which 

 annually costs sheep 

 owners thousands and 

 thousands of dollars. 

 Scab is very conta- 

 gious. It is caused by 

 an itching, mangy, skin 

 parasite, a kind of mite, 

 just big enough to be 

 seen by the naked eye. 

 The bite of this mange 

 mite or scab mite 

 raises itching blisters 

 on the skin and with 

 constant irritation and 

 scratching of the sheep 

 the skin becomes much 

 inflamed, the blisters 

 break and form yellow- 

 brown scabs which 

 give the name to the 

 disease. The scabby 



skin cracks and ulcerates and the wool falls out in bunches. Usually the 

 back and sides, rump and shoulders are the worst affected parts. The 

 picture, copied from a photograph, shows the actual work of scab mites. In 

 most sheep states the laws are very strict for treating scab in sheep, on 

 account of the contagion. It is known that old buildings, posts, or even 

 tufts of wool on bushes or range, will harbor these mites and start the 

 infection in a healthy flock. 



Treatment Dipping is the only remedy. There are various kinds of 

 dips; and while all of them kill the scab mite, many are ex- 

 tremely dangerous, if allowed to get into the mouth, eyes or nose. Such 

 poisonous dips not only endanger the sheep, but since they burn, curl and 

 stain the wool, they are absolutely unfit to use for dipping purposes. It 

 has long been a scientific problem to find a dip solution that would actually 

 kill the scab mite, and at the same time be safe for the sheep. Where the 

 fleece has already been destroyed by the disease, the poisonous dips (such as 

 arsenic, lime and sulphur, tobacco, etc.), are still unsafe to use on account 

 of the chance of the sheep's getting the dip in the mouth, nose or eyes, or 

 the danger of lambs nursing. We positively guarantee Conkey's Nox-i-cide 

 Dip and Disinfectant to be safe, non-poisonous, non-corrosive, and that it 

 does not even stain the wool. It does kill the scab mites. But as with e-very 

 dip, a second treatment 10 days later is necessary to kill the nits which Ijatch 

 out. The female scab mite lays its eggs (usually ten eggs) under the-.scab 

 and these hatch out and mature in about 15 days. Thus it is easy to see

 scab mites (psoroptes communis). These insects are larger 

 than the head mite and are easily seen by the naked eye.
