PARTURIENT PARESIS (Milk Fever) 



Milk fever is a non-febrile disease of cattle, swine and goats 

 occurring at or following parturition and characterized by general 

 paralysis and usually unconsciousness. 



The disorder is common among cows, especially valuable dairy 

 cows, which are heavy feeders and deep milkers. It usually occurs 

 at the acme of lactation in cows that are well bred and in prime 

 condition. Thin cows or very fat cows do not seem predisposed. 

 When delivery has been difficult, parturient paresis is less apt to 

 occur than when the birth has been easy and the expulsion of the 

 afterbirth prompt. Usually it occurs in cows from the third to the 

 fifth calving. The causes are unknown at the present writing. 



SYMPTOMS 



The symptoms usually begin twelve to forty-eight hours after 

 delivery. A few cases are recorded where the attack came on dur- 

 ing or before birth. The principal symptoms are suddenly develop- 



A typical case of milk fever in first stage.
