The sizes of the doses are as follows: 



Lambs - % ounce 



Slieep V2 ounce 



Calves V2 ounce 



Yearling steers - - 1 ounce 



The dose for each animal is measured and mixed separately in lin- 

 seed oil, milk, or flaxseed tea, and administered by means of a bottle or 

 drenching tube. Gasoline should not be given in water. 



OTHER REMEDIES. 



Many other remedies in addition to those mentioned here have been 

 used in the treatment of stomach-worm disease with more or less suc- 

 cess. Several of the coal-tar dips on the market are recommended by 

 the manufacturers for the treatment of worms and the action of some 

 of them is mucn the same as that of coal-tar creosote. 



It is not the policy of the department to recommend the use of any 

 particular proprietary remedy, and as the action of some such agents 

 is very uncertain it is suggested that, if it is desired to use them, they 

 be used with caution and only in accordance with the printed directions 

 on the package. Whatever remedy is used, it is wise to test it on two 

 or three animals before the entire flock is dosed.

SCAB IN SHEEP. 

 Extracts from U. S. Department of Agriculture, Farmers' Bulletin No. 159. 



INTRODUCTION. 



The disease commonly called sheep scab is one of the oldest known, 

 most prevalent and most injurious maladies which affect sheep. It is a 

 contagious skin disease caused by a parasitic mite. Investigation has 

 shown that me disease is not hereditary, as the parasites which cause it 

 live on the external surface of the body. It is possible, however, for a 

 lamb to become infected from a scabby mother at the moment of birth 

 or immediately thereafter. The treatment must consist of external dies 

 to "purify the blood." 



The disease is one of the most serious drawbacks to the sheep industry 

 and results in enormous financial losses. The losses are due to the shed- 

 ding of the wool, failure of condition, and the death of the sheep. Yet, 

 despite its insidious nature, its ease of transmission, its severe effects and 

 its prevalence in certain localities, it is a disease which yields readily to 

 proper treatment. If all the sheep owners of the country would dip sheep 

 regularly and thoroughly, there is no reason why this scourge should 

 not be totally eradicated from the United States. 



In many cases, particularly among owners of small flocks, there are 

 erroneous ideas prevalent regarding the exact nature of the disease and 

 the methods by which it may be eradicated. It is to meet the demand 

 for information on the subject that this bulletin has been prepared.
