Common Parasites of Farm Animals 



INTRODUCTION. 



We have no accurate means of determining the losses to our live 

 stock industries through parasitic infestation and the diseases inci- 

 dent thereto. It is sufficient to say that without a doubt these losses 

 amount to several millions of dollars to the live stock owners of 

 Georgia every year. A few of the most common animal parasites 

 found in the state are the Cattle Tick; Hog Louse; Bot Fly of Cattle; 

 Stomach Worm of Cattle, Sheep and Goats; Kidney Worm of Hogs; 

 and Intestinal Worms of Horses, Hogs, Sheep and Dogs. 



The Cattle Tick, (Margyropus annulatus) is undoubtedly the 

 greatest drawback to the development of a profitable cattle industry 

 in the state and the direct cause of greater financial loss to cattle 

 owners than any other single factor. 



The Hog Louse (Hematopinus suus) causes enormous losses, yet 

 the parasite is not difficult to control through the use of proper 

 measures. 



The Bot Fly of Cattle (Hypoderma lineata) is responsible for loss 

 of flesh and milk, lack of growth and development and great com- 

 mercial damage to hides. 



The other parasites mentioned above are all responsible, in greater 

 or lesser degree, for loss of condition and vigor and in some cases 

 the death of animals. 



Several forms of parasites infesting farm animals are transmissible 

 to people and their presence constitutes a serious menace to the 

 health of the people in the locality in which they are to be found. In 

 this connection it may also be stated that several parasites that in- 

 fest people are transmissible to farm animals and that measures of 

 control practiced will have beneficial effect in both directions. 



The importance of the subject of parasites is so great that its 

 study is necessary on the part of the live stock man in order that 

 he may be able to prevent the enormous losses, make the animal 

 industries more profitable and at the same time produce a more 

 healthful meat supply. 



It is the purpose of this bulletin to discuss the most important 

 forms of animal parasites, giving a brief description and life his- 

 tory of each together with treatment for destruction or removal, 

 and recommendations of measures of sanitary precautions and of 

 disinfection.
