All dairymen are aware that their animals do better, eat 

 better, digest their food better, and give more milk in good, 

 clean, bright surroundings (barns) than can be secured under 

 reverse conditions. Pure air is necessary for the good health 

 of every animal, and especially necessary for the working ani- 

 mals. 



To command this feature, a certain amount of air space 

 must be allotted to each animal. This amount of " air space " 

 varies to a certain extent with regard to the size of the animal. 

 Figures have been submitted from time to time as to the amount 

 of air space necessary for cow barns when situated in country 

 or cities, and in accord with the size of the animal. 



(It is no place to keep cows in the confines of a city. It 

 should be proscribed by law.) 



One should not build a barn for the housing of cows unless 

 he has air space enough to allot to each animal. The rule has 

 been that the minimum air space allowed for each animal should 

 correspond to one cubic foot for each pound weight of the ani- 

 mal's body, and we think it would enhance the good health of 

 the animals if they were given two cubic feet of air space, in- 

 stead of but one cubic foot. 



We know of barns where large herds are kept, where the 

 latter space has been given to each animal, and with plenty of 

 sunlight admitted. This herd is never sent to pasture. It is 

 turned out once a day, in suitable weather, into a paddock ad- 

 joining the cow barn, for a few hours only. 



Every precaution known to science is observed in keeping 

 all disease out of this herd, especially Tuberculosis. Whenever 

 any new stock are added they are not placed with the herd un- 

 til after they have been subjected to a thorough examination 

 and tested out with the " Tuberculine Test." 



They are studied, the milk is examined by the microscope 

 as well as by the Babcock Test. Cultures are made of their 

 dung for the germs of Tuberculosis. Cultures are also taken 

 from the mouth, and blood counts are made. 



They are detained in what is called the ' ' observation barn ' ' 

 from four to six weeks, regardless of any certificate of health 

 that accompanies the animals, before they are allowed to be 

 placed with the herd.
