LUMPY JAW (AcrixoMYCOSis). 



The first appearance is a painful swelling on either jaw. Later this may break 

 and discharge a yellowish, sticky pus. The bone is eaten into and the teeth may 

 be affected. Sometimes the tongue is the affected part* The parasite causing this 

 disease must be destroyed as quickly as possible. Paint or inject the affected parts 

 daily with tincture of iodine. Give also internally iodine of potash 2 to 3 drams 

 daily (in two doses) with a pint of warm water. This should be kept up for two 

 weeks, discontinued for a week, and then repeated if necessary. 



FAILURE TO BREED STERILITY. 



During a normal heat period in females a ripe egg or ovum from the ovary 

 descends into the Fallopian tube. Without the presence of this mature egg and its 

 union with the male sperm conception cannot occur. Persistent abnormal sexual 



excitement may not be accompanied by the 

 rij>ening of the ovum, in which case the female 

 rile. In some cases the male spermatozoa 

 may lack the vitality necessary to reach and 

 fertilize the ovum, due to the bull being over- 

 worked, underfed, or in want of exercise. Fluid 

 extract of nux vomica may be given to induce 

 animals coming into heat. Commence with !-_. 

 dram and gradually increase the dose. Should 

 the animal show an involuntary twitching of the 

 muscles or restlessness and excitability after 

 the medicine has been given for some time, go 

 hack to the first dose and repeat Nux vomica 

 is poisonous and must be carefully used. Fat 

 animals must be made muscular by exercise and 

 thin animals built up by generous feeding. 

 Where the young are suckling, they may have 

 to be weaned before the mother will breed. 

 Errors in feeding must be corrected: more 

 protein may be necessary. A young robust bull 

 should be tried. Mechanical obstructions often 

 prevent conception. Vaginal tumours may have 

 to be removed, or a persistent hymen obliterated, 

 or the mouth of the womb may need to be 

 opened artificially (before service) by a qualified 

 practitioner. Sterility may also be caused by 

 the abortion germ. 



Yeast Treatment for Sterilitt/. As sterility 

 may be due to any one of a number of different 

 causes, there can be no one cure for all. In 

 many cases the yeast mixture has aided concep-

tion by bringing about a right condition of the vaginal passage. 



The mixture is made as follows: Thoroughly moisten one cake of comi': 

 yeast or dried yeast with fresh boiled water, used lukewarm. Allow to stand in a 

 warm room for at least twelve hours; then stir in a pint of lukewarm water and 

 let stand twelve hours more. At the end of twenty-four or thirty hours the mixture 

 may be used, after straining it through cheese-cloth. First cleanse the vagina by 

 syringing out with warm water; then inject the yeast mixture into the vagina by 

 means of a syringe or clean i^-inch rubber hose, with funnel stuck in the end which 

 is elevated above the cow. It is best to inject the mixture when the animal is first 

 seen to be in heat and have her bred when the period of heat is about over. The
