and dark in color, ana gradually changing to a yellow cast 'lha#e is much 

 loss in weight and the bird becomes poor. 



TREATMENT— Give free and open range if possible and see that birds 

 have plenty of exercise. Give as a purgative one rounded teaspoonful of 

 CONKEY'S POULTRY LAXATIVE to each two quarts of mash feed for 

 two days, then discontinue for two days and repeat. If this remedy cannot 

 be given in the feed, mix the LAXATIVE with a little sugar syrup and roll 

 into pills, giving each fowl one the first day and repeat the second day if 

 necessary. Change the diet, providing a supply of clover, or other green 

 food, especially in the mashes. _ Discard cornmeal, bread, potatoes, and all 

 starchy foods as much as possible, and substitute foods wliich are high in 

 protein, such as wheat, ground peas, oats, etc. Raw beef or green cut bone 

 will be found very beneficial. CONKEY'S POULTRY TONIC given ac- 

 cording to directions will be found excellent for bringing the birds back to 

 proper condition. 



BLACKHEAD 



(Infectious Entero-Hepatitis.) 



This is a parasitic disease which attacks the caeca, sympathetically affects 

 the liver and is confined principally to turkeys. 

 The Caeca is a sort of blind double-intestine and, 

 much like the vermiform appendix in human 

 beings. Its use is not fully understood. We do 

 know, however, from dissection, its exact form 

 in both normal and diseased condition. 



CAUSE — The disease is caused by a parasite 

 (Amoeba meleagridis) which is taken into the 

 digestive system with the food or drink. It at- 

 tacks the mucous membrane of the caeca and 

 brings on intense inflammation. The micro-para- 

 sites find their way from the diseased caeca into 

 the liver, which brings this disease under the head 

 of Liver Trouble. 



SYMPTOMS— General Weakness, loss of ap- 

 petite, and an almost constant diarrhoea. As the 

 disease progresses, the head becomes discolored, 

 turning quite dark, which gives the disease its 

 name.

TREATMENT— This must be largely preven- 

 tive. CONKEY'S POULTRY TONIC in the 

 mash food, and CONKEY'S CHOLERA REME- 

 DY in the drinking water, have been found ef. 

 fective. We have, however, a special BLACKHEAD REMEDY. While 

 we do not guarantee this remedy to cure all cases, it has proven so thoroughly 

 efficacious in so many instances, that we feel compelled to put it on the 

 market for those who wish to take advantage of it. (See Special Remedies, 

 page 68. 



Where the disease has reached its height heroic measures must be adopt- 

 ed. Remove all affected birds and disinfect the premises, utensils, houses, 

 etc., with CONKEY'S NOX-I-CIDE. Give the preventives to those not at- 

 tacked and give CONKEY'S SPECIAL BLACKHEAD REMEDY to the 

 affected fowls which you have separated. Keep up constant disinfection.
