remaining undigested. The absorption of fat and digestible carboliydrate 

 is on the contrary fairly good. It is however always necessary for each 

 food material, not only to be chemically and calorimetrically analysed, 

 but to be administered to the animal and estimations made of the com- 

 position and energy coiutent of tlie fseces so tliat the amount absorbed 

 and its energy value may be armn-atelv calculated.

IMPROVING THE MILK YIELD. 



/. ;]/. B. Connor, Dairy Supervisor. 



Silage as a Factor of Success. 

 The more I am brought into contact with the dan-y farmers supplying 

 milk to our large cities, the more I am convinced that silage is an im- 

 mediate and necessary requirement that deserves more than passing notice. 

 I do not suppose that any section of the community is so conservative in its 

 methods as the dairy farmer. Certainly none is so difficult to move out 

 ot a groove, no matter what that groove leads to. It is this alone, to my 

 mind, that prevents the sensible course of growing plenty of feed 

 for their dairy herds from being carried out. I find when inspecting 

 herds in different parts of the State that the question of the preparation of 

 silage as a necessary stand-by is occupying much attention at the present 

 time amongst the daindng communitv. With this in view, and the fact 

 that a heavy growth of grass and other favorable conditions may be rea- 

 sonably expected this season throughout Victoria, I wish to draw attention 

 to the benefits which can be obtained by seizing the great opportunity which 

 the fields and pastures afford ; for it is surprising how many know 

 little or nothing about the process or method of preserving and converting 

 into silage the green succulent grass which is so plentiful everywhere 

 durinc snrinc: time.
