Bulletin 304 



The results with the several calves in each lot may now be averaged and 

 summarized : 



Table VII. Summary of Tables II, V, and VI, for 1907-1908 



Conclusions from work in 1907-8 



A careful study of Tables II, V, and VI, which summarize the results 

 for each calf, and then of Table VII, which shows the average for each 

 lot, warrants the following conclusions: 



(i) While skimmed milk gives the best results as a substitute for whole 

 milk, good strong calves can be raised without milk of any kind after 

 the third or fourth week. 



(2) It will cost at the present prices of milk, skimmed milk, hay, grain, 

 etc., $12 to $15 to raise a calf to five months of age. 



(3) Under normal conditions, a calf well cared for and properly fed 

 should make an average daily gain of one to one and one-half pounds 

 during the first four months of his life. 



(4) Schtmiacher Calf Meal does not appear from this feeding trial to 

 be a complete substitute for skimmed milk, yet the gains from the use 

 of this meal are good and the cost of a pound of gain is fairly low. 



(s) In the results derived from feeding Lactina Suisse, the gains per 

 day became greater as the calves grew older, but this food did not seem 

 to be nearly equal to skimmed milk or Schumacher Calf Meal at any 

 corresponding periods of age. 



II. EXPERIMENT AT CORNELL STATION, 1908-9 



Since a part of the calves in the experiment of 1907-8 were older than 

 the others, it was considered best to repeat the experiment in 1908-9, 

 keeping a record of each calf from birth. 



The calves to be fed on the different foods in 1908-9 were not selected 

 in any way. The plan was to put each calf on experiment at birth and
