Substitutes for Skimmed Milk in Raising Calves

to feed equal nirmbers of calves on each food during the course of the 

 experiment. From the results of 1907-8, it was considered not worth 

 while to continue feeding Lactina Suisse because of its high cost and 

 because of the generally poor results obtained by its use. The foods used 

 for trial were skimmed milk, skimmed milk powder, Schumacher Calf 

 Meal and Blatchford's Calf Meal. Calf No. i was fed Schumacher Calf 

 I^/Ieal, calf No. 2 Blatchford's Calf Meal, calf No. 3 skimmed milk, and 

 calf No. 4 skimmed milk powder. By alternating the calves as they were 

 born during the fall, the lots fed on the different foods would thus have 

 nearly equal numbers. However, owing to the fact that some of the bull 

 calves were sold from time to time and thus dropped from the experiment, 

 the calves in Lot D, fed skimmed milk, finally numbered seven, those 

 in Lot E, fed skimmed milk powder, numbered six, Lot F, fed on Schu- 

 macher Calf Meal, numbered four, and Lot G, fed on Blatchford's Calf 

 Meal, numbered four. 



All records of food, weight, etc., were kept separately for each calf. 

 The milk or gruel and the dry grain were weighed separately for each 

 calf. The hay eaten by all the calves on experiment was weighed daily, 

 and at the end of each month the amount of hay was averaged for each 

 calf according to his age. 



Each calf was kept on experiment from birth until he was 150 days 

 old, or through the first five months of his life. Table VIII gives in brief 

 the breed, sex, date of birth, etc., for each calf in the experiment. 



Each calf was weighed at birth and every Thursday thereafter up to 

 and including the last Thursday before he was 150 days old. He was 

 then weighed when 150 days old. The record of these weighings for each 

 individual is shown in Table IX. By weighing the calves each week, 

 a check was kept on their development.
