BOVINE OBSTETRICS 



The diagnosis is not difficult. In the first instance we 

 define the position by the head lying under the fore legs, in the 

 latter by the hocks and tendo Achilles. 



Treatment. — As long as no part of the calf has entered the 

 pelvic canal, treatment is simple. The head is placed upon the 

 fore legs by placing the hand against the head and turning it. 

 The fore legs are fixed and a loop placed around the lower 

 jaw. After the head is once placed upon the fore limbs the 

 calf turns by itself. When the hind legs have passed into the 

 pelvic canal in the dorsal position, they are pushed back, and 

 rotation around the long axis is attempted, by introducing the 

 hand between the hind legs of the calf as far as the symphysis.

One hand now fixes the hind legs, the other twists the hind- 

 quarters ; also, by placing one leg across the other one and 

 pulling on it, rotation of the calf can be effected.

Diagnosis. — Both fore legs lie with the claws in the vagina, 

 the flexion surface turned upwards. On internal examination, 

 one feels the sternum, anterior surface of the neck and usually 

 the head, by gliding along the exterior surface of the fore legs.
