504 MANUAL OF MODERN FARRIERY 



In tracing the original cause of the outbreak of 

 contagious abortion, and its continuance in a herd, 

 it is all-important to remember that the contagion 

 may be carried by the bull as well as the cow, and, 

 all things considered, it is advisable to keep two 

 bulls for service in a herd where contagious abortion 

 has obtained a footing. It is also advisable to 

 divide the herd into two portions, and to graze 

 and house all the cows who have aborted by 

 themselves, and to serve them by the one bull. 

 The sound cows and the other bull should congregate 

 together, and, if possible, have separate attendants. 



FALLING DOWN OF THE CALF BED. 



The extent to which this takes place varies. In 

 some cases it is only a prolapsus of the walls of 

 the vagina, and is only seen to take place when 

 the cow lies down. In other cases not only the 

 vaginal wall descends, but also the whole body of 

 the womb or calf bed. 



REMEDIES. Where the prolapsus is restricted to 

 the vagina, and only takes place in the recumbent 

 position, all that is required in general, is to lower 

 the floor in front, or raise the floor behind, so that 

 when the animal is lying down, her body behind 

 will be raised up, and the calf in the womb will 

 gravitate forwards, instead of downwards and 

 backwards. 



When the womb has become inverted the first 

 thing to be done is to remove the placental 

 membranes, support and protect the womb with 

 a clean cloth underneath, and have it returned at 

 once, and this as a rule can only be accomplished 

 by a veterinary expert, so that we need not describe 

 the operation in detail.
