Ventilation of Stables 



Every stable should be equipped with a system of 

 ventilation that is capable of renewing in a short time 

 the air in the stable, taking in pure fresh air and eject- 

 ing the foul, dust-saturated air, without causing a 

 draught. 



In the milder climates, where the cows are going 

 in the pasture all the year round, the stables are as a 

 rule so lightly constructed that there is ample ventilation. 



In the colder ones the stables are made more sub- 

 stantial. No draught is coming thru the walls and the 

 doors are kept closed to keep the temperature of the 

 stable air up. Great care must be taken that sufficient 

 circulation of fresh air is provided for, and it will prove 

 an advantage to a dairyman, when constructing a barn, 

 to consult a farm adviser or County agent or other ag- 

 ricultural authority, about the most advisable system of 

 ventilation under the local conditions. Such advice is 

 free of expense and based upon careful studies, made 

 by competent men, on this important subject. 



The stable air may contain, as above stated, large 

 numbers of undesirable bacteria, resulting from manure, 

 hay, straw, bedding material, etc., which by air 

 currents, feeding and bedding, etc., come in motion, and 

 may fall in the milkpail. 



Consequently, no work should be done in the stables 

 immediately before or during the milking process, by 

 which dust of any kind is stirred up. 



Cleaning of the Stables 



The cleaning of stables and cows should do done be- 

 tween the milkings, taking care that sufficient time is 

 left for ventilation, before the next milking commences. 



In summer when the cows go in the pasture and are 

 only stabled to be milked, no bedding is necessary. After 

 the milking is finished and the cows have left the stables, 

 the manure is removed and if possible, the walls and
