DISEASES OF THE GENERATIVE ORGANS 7I 



It is always a wise measure to remove the sow 

 from the herd, as the abortion may be infectious and 

 spread rapidly. In this latter form prompt measures 

 must be taken against the spread of the disease. This 

 consists mainly in disinfecting the pens, burning the 

 afterbirth and dead pigs, and keeping the sows that 

 have aborted away from the herd. The leucorrhoea 

 that may follow should be treated by injecting the 

 womb and maternal passages with a one per cent, 

 water solution of some of the tar disinfectants daily, 

 and keeping up this treatment for as long a time as 

 necessary. The sow must not be bred until the dis- 

 charge from the parts has stopped. 



INFLAMMATION OF THE UTERUS AND VAGINA 



Causes. — Inflammation of the womb and the pas- 

 sages leading to it frequently occurs as a complica- 

 tion of a difficult birth, or as a result of the retention 

 of dead fetuses and decomposition of the afterbirth. 

 Herdsmen, when assisting in a difficult birth, may 

 injure and infect the parts with germs, causing the 

 lining membrane of the uterus and vagina to become 

 irritated and inflamed. Dirty hands, cords, and in- 

 struments are the usual sources of germ infection at 

 the time of birth. 



Symptoms. — The disease usually occurs in connec- 

 tion with a difficult birth and the retention of one or 

 more dead pigs. The character of the symptoms 

 depends on the extent of the inflammation. In se- 

 rious cases the temperature is higher than normal.
