days and fast lose flesh, showing all the symptoms 

 of ill health. 



One of the commonest causes is feeding dirty, 

 souring or decomposing factory skim milk in large 

 quantities at long intervals; even sweet skim milk 

 so fed may produce the trouble. To prevent scours 

 give calves a perfectly clean, airy, sunny pen and 

 yard attached. Separate any calf that scours. 

 Avoid dirty, dark, damp, poorly ventilated pens in 

 which scouring calves have been. Give all food 

 from clean, scalded, sun-dried vessels. Feed small 

 quantities of food often ; and in milk mix lime water 

 freely two or three times a week as a preventive; 

 and daily when scouring has been experienced. 

 Also see that the udders of cows nursing calves 

 do not become contaminated with manure or other 

 filth. 



Wash udders with a two per cent solution of coal 

 tar disinfectant before any calf is allowed to suck 

 for the first time, and then repeat to keep the udders 

 clean. Also disinfect the navel of each calf at birth 

 with a 1-500 solution of corrosive sublimate and 

 repeat the application twice a day until the navel 

 is perfectly healed over. At the first sign of scours 

 give castor oil shaken up in milk. Two to 6 table- 

 spoonfuls is the dose according to the size and age of 

 the calf. Follow two or three times daily with a i to 

 2-teaspoonful dose of a mixture of one part of salol 

 and two parts of subnitrate of bismuth in milk or 

 water. For calves scouring on skim milk mix in 

 each pint of milk i teaspoonful of a mixture of half 

 an ounce of formaldehyde in I5j4 ounces of dis- 

 tilled water, to be kept in an amber-colored bottle.
