VETEEINAEY HYGIENE 



The cubic space allowed to a cow occupying a byre of this 

 kind is 446-6 feet. We are told the Ayrshire County Council 

 fixes the minimum cubic space for a cow at 375 feet, and 

 considers a fair size for a byre is one that affords 450 

 cubic feet to the occupants ! 



Fig. 133 is described by Henderson as the more common 

 form of shed ; the cows face the outer walls with a passage 

 down the centre. The space afforded per head is 429 cubic 

 feet.

Fig. 134 is regarded by Henderson as the best and is also 

 the most expensive ; it affords 578 cubic feet per head. 



The ventilation in all these buildings is whatever may 

 find its way through such windows and doors as exist, 

 while the outlet is an opening in the ridge of the roof, 

 which is common to this part of Scotland. 



Henderson proposes to light his cow-house from the 

 roof and not from windows ; for the purpose of inlet venti- 

 lation he introduces pipes 6 inches in diameter in the wall 

 close to the level of the wall head, and controls the amount 

 of air these admit by means of a piece of wood so arranged
