The calves thus reared were kept to be brought into the dairy herd, 

 and although weights are not given, sliowing their later rate of increase 

 in live weight, it is reported that the animals of the different lots 

 appeared to possess equally good constitutional vigour. 



It will be noticed that the cost per lb. of live weight increase was 

 very satisfactory as compared with that made in the experiments already 

 described. 



It may perhaps be considered that I have not solved the question 

 of how to rear calves on milk substitutes, as Lot II., though not fed 

 milk in the dry condition, were fed the dry matter of milk, and that 

 the food of Lot III, contained at least a little condensed milk. All 

 I can say is that at present there appear to be no really good milk 

 substitutes for calf rearing generally available, but assuming the milk 

 producer makes butter or cheese, he has separated milk or whey to 

 fall back upon, which, as has been shown, can be usefully employed 

 for the purpose; and if he sells all his milk, he can, if procurable, 

 purchase separated milk up to at least 3d. ner gallon, and raise calves 

 economically on it (and cotton seed oil) even at that price. 



Should separated milk powder* be available at less than 3d. per lb., 

 it would seem to form a fairly economical food on which calvea can 

 be profitalilv raised, if fed with cod liver oil or some food butter-fat 

 substitute. 



In conclusion I need only ein,phasize the importance of strict clean- 

 liness in all matters connected with calf rearing; the scalding of the 

 feedinsr buckets and other utensils in which the food is fed or stored, 

 lime-washing the walls of the calf-pen& periodically, and the use of 

 sufficient bedding material for the calf to have a dry bed at all times. 

 Cleanliness is the chief factor, and because a man finds he is unable to 

 rear calves on milk fat or milk substitutes, which others have found 

 satisfactory, may be due to the neglect of these points, and not to any 

 faultiness of the food.
