 considt'rable portions of all the nutrients an- 

 not dip'sted. Consefiuently, in «n-ery ration therr 

 is more or less material of which the animal 

 makes no use, and which may be saiil t<» merely 

 add to the l)ulk of the rati(»n. Water and liber 

 are, above all other thinirs, the substances wliieli 

 give bulk to a fod(h'r or ration.

 of either or both of tlieso substances are said to 

 b.' coarse or bulky ; fodders which have a min- 

 imum amount are said to be concentrated. If 

 a ration is too liulky, the animal is unable to 

 eat enough to obtain sufficient nutrients. On 

 the other hand, a ration may be so cunceutrated 

 that the proper amount of digestible nutrients 

 do not sufficiently distend the digestive organs 

 so that the ga.stric flui«ls may fully act. This is 

 particularly the case with nuninant.<* (38*2-384,
