ACUTE SERO-FIBRINOUS PLEURISY IN CATTI.E. 



Milch cows and work oxen most liable. Causes Damp buildings and 

 locations, sudden transitions from heat to cold, exposure when fatigued, etc. 

 Symptoms, rigor, reaction, cold horns and limbs, later hot, excited pulse, 

 catching breathing, hyperthermia, 104° to 105°, tender chine andintercostals, 

 friction sound, later dullness, creaking, weaker murmur, subacute cases 

 often tuberculous, effusion unilateral, chronic cases. Lesions, as in horse 

 with superficial marbling of lung. Treatment, laxative, warm drink, 

 compresses, derivatives, sedatives, diuretics, heart tonics, diaphoreiics, 

 thoracentesis. 



This is not common in young growing cattle, but is more 

 frequent in milch cows and work oxen. It is due to the same 

 causes as in the horse, and especially to chills when heated, 

 damp buildings and locations, cold draughts between open windows 

 or doors, and cold storms. The greatest danger comes from 

 hot, close stables, like many distillery stables, approximating to 

 the temperature of the animal body and from which the stock are 

 suddenly turned out of doors, or shipped by car or boat with a 

 temperature near zero, and, above all, if furnished ice water to 

 drink. Such animals taking no exercise to increase the circu- 

 lation and heat, are especially liable to shiver and contract illness. 

 Rigors, too, are easily induced in animals standing in hot buildings, 

 when, in connection with the cleaning, an adjacent door is thrown 

 wide open or two on opposite sides of the house. Working oxen 

 heated with exercise and then exposed to extreme cold and con- 

 pulsory inaction are endangered. 



Symptoms. The attack is manifested by the same general 

 symptoms as in the horse. The rigors are often very well marked, 

 especially over the shoulder ; the tenderness of the chine and 

 intercostal spaces is striking ; the breathing is catching but there 

 is rarely the same restlessness as in the horse ; the bowels are 

 costive, appetite and rumination impaired or suspended, and the 

 paunch is often distended with gas. The tenderness of the spine 

 and intercostal spaces, the friction sound of the pleura, and the 

 maintenance of the respiratory murmur and the normal resonance of 

 the lung, become the ultimate diagnostic symptoms. The pulse 

 may be 70° and upward, the temperature above 104° to 105".
