DISEASES OF CATTLE 149 



condition described shows a functional weakness, and tonic treatment is 

 necessary to build up the bodily vigor. 



LICE The lice that affect cattle are blood-suckers, with narrow heads 

 and long trunk-like sucking tubes. They leave the cattle when 

 turned on grass, but the nits remain in the stable so that thorough cleaning 

 and disinfecting of the premises is necessary to get rid of these pests. 



Treatment Conkey's Nox-i-cide Dip and Disinfectant, mixed with 60 to 

 75 parts water, should be sprayed or applied with a brush as 

 convenient. Begin at the head and work back over the animal, as the lice 

 will try to get out of the way of the mixture and especially try to hide 

 away in the ears. Go over the whole animal thoroughly and get at every 

 part with the Nox-i-cide Dip and Disinfectant. It will certainly kill the 

 lice, but the nits will hatch in 10 days and the animal should then be 

 sprayed again. In cold weather the mixture should be made with warm 

 water so as to avoid chilling, and the animal should be dried in the sun- 

 shine or a blanket put over it until thoroughly dried off. Instead of 

 Nox-i-cide Dip and Disinfectant, Conkey's Lice Powder can be used, sifting 

 it over the body thoroughly and rubbing it in so as to get to every part. 

 With the powder there is no danger of chilling, but powder is more trouble- 

 some to apply over a large surface than Nox-i-cide Dip and Disinfectant. 

 Treatment includes going over the barn or stable thoroughly, cleaning and 

 disinfecting, and if possible whitewashing it. 



LUMPY JAW This is a tumor-like growth, usually on the jaw but 

 sometimes on the tongue (wooden-tongue), or it may 

 affect the lungs. It is due to bacterial infection from the ray fungus, which 

 exists naturally on spears of oats, awns of barley, thorns, etc. If the sensi- 

 tive membrane of the mouth is cut by a bit of sharp forage, or if there 

 is a scratch or sore of any sort in the mouth, or a bad tooth, the animal is 

 easily infected by this ray fungus (in fact, inoculated) and symptoms of 

 lump jaw may quickly follow. At first there is a lump on the jaw bone, or 

 just back of the angle of the jaw, and in the early stages, while the bunch 

 is soft and not attached to the bone itself, it is quite easy to cure. If 

 neglected the lump continues to grow and when broken discharges thick, 

 yellow matter. This discharge is contagious and if any of it drops on the 

 food or the pasture other cattle are likely to be affected. We know of 

 instances where three generations kept on the same pasture developed lump 

 jaw. It usually starts with young cattle and in the last half of the year, 

 when sharp grain and hay is fed and mouth-sores are more common. 



Treatment As soon as the lump is discovered apply Conkey's Absorbent 

 as directed, first cutting away the hair. If the lump is small 

 this will absorb it. If the lump is large, this treatment will soften it so 

 that it can be opened and cleaned out, and the tumor r abscess then 

 packed with gauze or oakum saturated in Conkey's Absorbent. Or you can 

 dress these fistulous tracts with a lotion made by dissolving copper sulphate 

 (blue vitrol) 10 grains to one ounce of pure water. To hasten recovery 

 internal treatment can be given as follows, with due attention to the special 

 caution: Give potassium iodide, 2 to 3 drams daily, until the animal shows 

 signs of scurf, loses appetite, droops, etc. Then stop for a few days, then 

 commence again. Among veterinarians iodide of potash is considered a 

 specific for this disease. It is successful in 3 out of 4 cases, but if no im- 

 provement follows after four or five weeks the treatment should be given 

 up entirely. This drug should be used with full knowledge that it causes
