From the figures presented, the buttermilk lot did not make 

 quite as rapid gains as the skim-milk lot. Nevertheless the ex- 

 periment shows beyond a doubt that calves can be successfully 

 raised on buttermilk. In this experiment the buttermilk calves 

 had less trouble from scours than the skim-milk calves. 



Feeding Whey. 



While there are comparatively few cheese factories in the 

 state, they are numerous enough to make the question of how to 

 utilize whey an important one. Whey, unlike skim-milk, has 

 the casein as well as the butter-fat removed. Our experience 

 consists of two trials; the first one began January 31, 1900, and 

 extended to March 21 of the same year. 



On account of the low nutrient quality of whey, an effort 

 was made to increase the nutrients of the calf ration by feeding 

 plenty of alfalfa, Kafir-corn meal, oats, and soy beans. This 

 ration figured out very nicely as far as composition was concern- 

 ed, but when we came to feed it we found that we had two feeds, 

 namely, alfalfa and soy beans, that were very loosening, and the 

 combination of the two with whey was too much for the calves ; 

 we found later that it is impossible to feed soy beans in large 

 quantities, as they invariably cause scours. After the above 

 experience the grain ration was changed to Kafir corn alone. 

 The results of this experiment are recorded in table XIII.
