 I saw one case where the manger and floor of a box 

 stalj was literally covered in the morning with 

 boluses of partially masticated hay. It gave off a 

 very offensive odor, which was due to decomposition 

 of the saliva and food. Some animals will hold their 

 head to one side, in order to keep the feed from get-

 from one or both nostrils (from one side only if there 

 are carious teeth on one side, and from both sides if 

 there are carious teeth on both sides) with more or less
