Diseases of Animals 227 



The reason that no special mention of bleeding is made is that 

 it is not now considered the preventive that it once was. Some 

 people appear to have fair success with it, and others no success at 

 all. The Bureau of Animal Industry states that the evidence in- 

 dicates that bleeding, nerving, roweling or setoning have neither 

 curative nor protective value and, therefore, should be discarded for 

 vaccination which is now widely used as a preventive. 



Poor Feeding, Depraved Appetite. 



/ have three cows. They have been fed alfalfa hay all zvinter and 

 are in very good condition and seem otherwise in good health, and have 

 salt to run to. Every time they chance to come to the yard they will 

 pick up an old bone and chetv it for perhaps a half hour. I alzvays take 

 the bone aivay from them zvhen I discover it. 



These cows have a depraved appetite, owing to the fact the 

 tissues of the body are crying out for something lacking that is re- 

 quired in the S5fstem. Administer the following powder; also put 

 a lump of lime in the watering trough: Pulv. gentian, 1 ounce; 

 pulv. elm bark, 2 ounces; pulv. iron sulphate, 1 ounce; pulv. bicarb, 

 soda, 4 ounces; pulv. aniseed, 2 ounces; pulv. red pepper ^ ounce; 

 pulv. oilcake meal 10 pounds. Mix thoroughly and give a table- 

 spoonful in scalded grain once daily. 



Cows Swallowing Foreign Substances. 



We recently lost a valuable cow, and when zve opened her we found 

 a large tumor or abscess at the top of the heart as large as a gallon jar. 

 What caused it, or is there any danger of other cozvs taking it, and if 

 so, what can we do? 



This is a common disease among cows and is called traumatic 

 pericarditis. The trouble ari.^es from the habit of the cows picking 

 up foreign substances such as wire, nails, or hairpins, and swallow- 

 ing them. Thej^ are taken into the paunch and the digestive move- 

 ments of this organ cause the foreign body to penetrate the lining 

 and enter the heart, where it gradually causes death as it enters 

 deeper. It is very common to find nails, etc., in the stomachs of old 

 dairy cows which are killed at the slaughter-houses. If you had 

 examined the animal carefully, you would find that some foreign 

 body had penetrated the heart and caused death. There is no danger 

 of any contagion arising from your cow. 



Defective Urination. 



/ have a cow that seems to be in good health and gives plenty of 

 milk. Nearly every morning when she is being milked she seems to 

 want to urinate and zvill stand letting the water drip from her. 



This trouble often results from the cows eating alkaline hay. 

 Give her two quarts of flaxseed tea daily. Mix it with her food in 

 which there has been placed one-half teaspoon of powdered Buchu.
