DISEASES OF POULTRY. Ill 



possible to eradicate the disease and obtain a healthy- 

 flock. 



The medical treatment of diseased turkeys has not 

 been successful and it is doubtful if it could be profit- 

 ably undertaken in any but exceptional cases. Among 

 the remedies most likely to be beneficial are sulphur, 

 sulphate of iron, quinine, salicylic acid,benzonaphthol 

 and betol. Where a flock has recently been infected 

 it would be well to try these remedies with a view of 

 arresting the disease in the mildly affected birds, and 

 of preventing the infection of others by making the in- 

 testinal contents unsuitable for the multiplication of 

 the parasite. Sulphur 5 to 10 grains, sulphate of iron 

 1 grain may be combined and given at one dose. Or 

 give benzonaphthol 1 grain, salicylate of bismuth 1 

 grain. Or give sulphur 10 grains, sulphate of iron 1 

 grain, sulphate of quinine 1 grain. Hyposulphite of 

 sodium may be useful in doses of 2 to 4 grains, or be- 

 tol in the dose of 1 grain. It is necessary that such 

 remedies be repeated two or three times a day and 

 continued for a considerable time to obtain results. 

 The doses mentioned are for birds weighing four or 

 flve pounds. 



PARASITIC WORMS WHICH INFEST THE DIGESTIVE 

 APPARATUS. 



A large number of species of animal parasites are found 

 in the various organs of the digestive apparatus of the 

 domesticated birds . Some of these parasites cause dis - 

 turbances of the digestive functions or serious disease, 

 while others are apparently harmless. Those only are 

 referred to in detail which are of most importance as 

 disturbers of nutrition or producers of disease. The 

 parasitic worms may be grouped as tapeworms, flukes, 

 roundworms, and thorn -headed worms.
