5O ELEMENTARY TREATISE ON STOCK FEEDS AND FEEDING 



spiration of a horse is probably about 14 pounds of water per 

 24 hours. 



COMPOSITION OF HORSES' SWEAT. 



The mineral matter in sweat is very high and exists princi- 

 pally as soda and potash. The nitrogenous matters (albumin and 

 globulin) make up most of the organic matter. It will be ob- 

 served that the mineral matter exceeds the organic matter; in 

 horses which have sweated freely the hair mats, due to the nitrog- 

 enous substance, albumin, and is often covered with salty matter 

 due probably to the salts excreted. The loss of albumin perhaps 

 accounts for the weakening effect in animals produced by sweat- 

 ing freely. 



Suggestion : Make a schematic drawing showing the entrance 

 of the nutrients into the blood, the circulation of the blood and 

 its functions.
