White Scour in Calves. 



of the disease and the modes of its transmission, and to 

 justify him in recommending, with full confidence in their 

 efficiency as preventive measures., the following simple rules r 

 White scour is generally the consequence of an umbilical 

 infection which occurs at the moment of parturition, occurring 

 through the wound resulting from the rupture of the navel 

 cord. The disease may be warded off by observing exactly 

 the following precautions : — 



1. Provide the cows that are about to calve with dry and 

 clean bedding, and keep it in good condition until after the 

 calf is born. If possible, a special stall or loose-box should 

 be provided for calving cows. Strict regard to cleanliness is 

 of the utmost importance. 



2. When the cow shows signs of being about to calve, the 

 vulva, the anus, and the perineum should be disinfected with 

 a warm solution of lysol in rain water — 20 grammes of lysol 

 to one litre of water [i.e., two parts of lysol to one hundred 

 parts of water). The vagina should also be washed by 

 injecting, by means of a large syringe, a considerable quan- 

 tity of the same warm solution of lysol. 



3. Whenever possible, the calf should be received upon a 

 piece of clean sacking or some such material, or at least 

 upon a thick bed of fresh clean straw, unsoiled by urine or 

 excrement. Or the calf may be received into the arms of an 

 attendant, and held there until the treatment is completed. 

 The object is to keep the umbilicus or navel cord of 

 the newly-born calf from being soiled or infected before 

 treatment. 



4. The cord should be tied immediately after birth with a 

 ligature of twine which has been steeped in the lysol 

 solution ; the cord then should be cut about an inch below 

 the ligature. 



5. The portion of the cord still attached, as well as the 

 region of the umbilicus, should be dressed with the following 

 solution, applied by means of a large brush : — 



Rain water - - - i litre — if pint. 



Iodine .... 2 grammes = 31 grains (by weight) 



Iodide of potassium - - 4 grammes = 62 grains (by weight).
